Congratulations to Yuni Dewaraja, PhD, my little cousin

Published

"Dr Yuni Dewaraja, "my little cousin" in the essay, is the little girl on the right. On the left is her older sister, Aruni Dewaraja Wijewardena, who served as Foreign Secretary from 2022 to 2024".

It gives me a great sense of pride and delight to write this. We all change as we traverse the pathway of our lives. I have had very little contact with Yuni after I left Sri Lanka until now, but Yuni will always remain my little cousin. We moved in our different worlds outside of our home country with a trajectory that is remarkably similar.

Yuni Dewaraja is the William Martell endowed Professor of Radiology (Division of Nuclear Medicine) at the University of Michigan, where she has spent her entire career. She received her PhD in Nuclear Engineering from the University of Michigan in 1995, specializing in the area of radiation detection and measurement. With the recent Food and Drug Administration (FDA) approval of her invention, Yuni immediately becomes a trailblazer in her field, which opens a new chapter that will inevitably result in new ways of delivering radiation to patients with cancer. Truly, a gift to humanity.

The diagnosis of cancer strikes fear into the hearts of patients. Depending on the cancer site and type, there are four potential methods of treatment: surgery, chemotherapy, immunotherapy, and radiation therapy. Radiation is used as the primary treatment for tumors that are in places that are not amenable to surgical removal and for which there is no effective chemotherapy. It is also used as an adjuvant treatment after surgery to control residual tumor that surgery has failed to remove. To the patient who hears that radiation is necessary for control of the cancer, there is often a sense of dread. At the present time, that sense of dread is often justified by side effects of treatment. This may change with Yuni’s invention.

Sad to say, this is the limit of my knowledge regarding radiation in the treatment of cancer. I do not treat cancer patients or use radiation. For the past few days, I have tried to understand what Yuni has been doing for the past twenty-five years and failed miserably; her work is beyond my comprehension. I tried to decipher a Press Release about her work and had enormous trouble understanding the language of her academic world. Medicine is so specialized.

Dr. Yuni Dewaraja

Fortunately, upon request, Yuni sent me a summary of her work yesterday. This was wonderful. She writes:

“Radiation for cancer treatment can be delivered from external beams or as an internally administered radiopharmaceutical therapy, sometimes referred to as nuclear medicine therapy. Radiopharmaceuticals are designed to specifically target cancer cells, while limiting uptake in healthy tissue. The specific area I work in is called Radiation Dosimetry, which is the measurement and calculation of the ionizing radiation that is absorbed by different tissues in the human body.

“Early in my career, I was able to secure funding from the National Institute of Health to develop methods to perform personalized dosimetry calculations for patients undergoing nuclear medicine therapies. We first worked on dosimetry calculations for radioimmunotherapy, where antibodies labeled with radioactive iodine (I-131) target and destroy non-Hodgkins’s lymphoma cells.

“Accurate dosimetry was needed to determine how much of the I-131 can be injected without causing too much damage to the bone marrow. My group developed a software code to perform these calculations in a highly personalized manner starting with the patient’s own images. The Positron Emission Tomography (PET) and the Single Photon Emission Tomography (SPECT) images show how the injected radiotracer is distributed in the body.

“Computer Tomography (CT) images provide the density of the different tissue in the human body. Starting with these images, we used the Monte Carlo method to simulate how the radiation is transported throughout the body and where the radiation energy is deposited.

The Monte Carlo method is a numerical technique widely used in many fields for solving statistical problems.

 “Over the past 20 years, we have further developed our software, Dose Planning Method for Radiopharmaceutical Therapy (DPM_RPT), to expand its use in other therapies such as Lu-177 peptide receptor radionuclide therapy for neuroendocrine tumor and Lu-177 PSMA radioligand therapy for prostate cancer. An ongoing clinical trial at our university uses DPM_RPT dosimetry estimates to determine if additional external beam radiotherapy is needed to parts of the tumor that do not get enough radiation from radioembolization, a therapy where radioactive microspheres are implanted in liver tumors.

“Four years ago, I received an Academic Industry partnership grant from the NIH, where the goal is to work with industry to translate research findings and tools into clinical practice.  Working with the technology transfer office of our university, we licensed DPM-RPT to our industry partner GE Healthcare’s MIM Software. The software was recently approved to be marketed in the USA. Furthermore, to streamline the dosimetry process, DPM_RPT was coupled with other tools including Artificial Intelligence based contouring of organs such as kidney and liver on the patient images.”

 Yuni’s story is the successful first end-point to the work of an intensely dedicated medical researcher. It started off with entry into the prestigious PhD program at the University of Michigan. To be selected, she must have been one of the best graduates. Here she learned the basic rules of research and stimulates students to develop specific and highly selective topics to work on. The more successful of these PhD graduates like Yuni are offered faculty positions to begin, plan and execute their ideas. This initial research is funded by the university and carries with it collaborations with other like-minded scientists.

Now comes the hard part. The researchers must immerse themselves completely in their research. They must dedicate the rest of their lives toward producing results. They must obtain grant funding from various sources to continue.

The majority of researchers never attain success. Yuni is a golden exception, who was able to reach multiple objectives to get her research into the patient care world, transforming the lives of many patients now and into the distant future. Those who read about Yuni’s story must understand how exceptional her achievements are. Yuni’s research has led to over 150 publications in medical journals, and authorship of books.

Yuni’s parents were exceptional people. Her father became the Director of Archives of Sri Lanka. He may not have agreed, but I believe the major success in his life was to convince Lorna, my aunt, to marry him while they were students at Peradeniya. Lorna punchiamma was a brilliant historian who went to Oxford University as a Rhodes Scholar from the University of Ceylon. She published numerous papers and books on various aspects of Sri Lankan history.

Our families were close while my mother and aunt were alive and there are many stories. I will tell you just one: I must have been in my teens. I do not know why (I think this was when Lorna punchiamma was doing her stint in England as a Rhodes scholar). Yuni and her sister Aruni were staying in our house in Fifth Lane. My room had two beds added to accommodate the two little girls. One night we all went to sleep. In the middle of the night, Aruni wakes up and says she is thirsty and wants water. I get the water and we all go to sleep. A few minutes later, Yuni awakes and says: Praki aiya, bayai (frightened by nightmares). I remember sitting with her until she fell asleep again. Imagine: this little girl in Colombo turning out to contribute a miracle that has the potential to improve the treatment of millions of cancer patients all over the world.

Yuni, the world is grateful to you and your family is proud of you.

Complexities in global politics deepen as economic pressures intensify

Published

UK Prime Minister Andy Burnham meets Ukrainian President Volodymyr Zelensky in Kyiv. (BBC)

The present offer by the UK to strengthen Ukraine’s defense capabilities in the missile technology field in particular comes as ‘a stitch in time’ and the initiative is also likely to be appreciated considerably by democratic opinion world wide for the possible morale-boosting effect it would have on Ukraine. Besides continuous arms support, the conviction that the world’s frontline democracies are behind it would prove a huge plus in Ukraine’s eyes in its grinding fightback against the Russian invasion.

While continued US support for Ukraine could not be considered ‘a given’ any more, British Prime Minister Andy Burnham’s words during a recent visit to Kyiv that the UK would stand by Ukraine ‘for as long as it takes’ is the kind of assurance that Ukraine needs at present. For, the conflict in Ukraine is essentially a war of liberation conducted by the latter against an invader and deeply at issue here is the upholding of International Law and its foundational concepts, such as national sovereignty and a nation’s right to political self-determination. The world of democracy is of the firm view that the latter ideals cannot be compromised, come what may.

The UK has its work cut out in this connection. It would find it difficult to convince the Trump administration that it should staunchly stand by Ukraine but it could campaign vigorously with the rest of the West and the EU fold in particular to unflaggingly support the embattled and over-run country.

Ukraine has shown an impressive adeptness in using drone technology in particular against her enemy and has even manufactured her own hardware in this respect but using the relevant blueprints handed over by the UK for the manufacture of more sophisticated cruise missiles, for instance, may prove financially difficult, going forward. It is left to be seen whether the UK and the rest of the West who are with Ukraine will continue to be with her, considering their own rising financial constraints.

The latter impediments could only multiply in the future. Oil, gas and energy prices are on the rise and the latter costs are glaringly reflected in kitchens and meal tables the world over. As we go along consumer discontent would steadily intensify and governments, East and West, would need to figure out with considerable rigour and foresight how such disaffection could be ably managed. Failing which, in most democratic societies, the chances are that publics would be out on the streets demanding that their grievances be redressed forthwith.

These rising concerns are reflected in a recent move by some EU governments to consider imposing what is described as ‘a windfall tax’ on the profits specified major oil companies operating within their shores have made in the wake of the US-Israel war on Iran. The rationale apparently is to use such tax earnings to cushion the rising cost of living of their publics and bolster the respective countries’ social expenditure.

In a recent letter to the president of the EU Council the EU governments referred to said, among other things, while drawing attention to the ‘discontent that is growing over the rising cost of living’: ‘A common approach’ is needed that ‘ensures those who profit from the crisis contribute their share to reducing the burden on the general population.’ Meanwhile, Oxfam with reference to the above development is on record as calling for a ‘permanent windfall tax of at least 50% on profits exceeding a 10% return on investment.’

Such are the rising economic pressures on the majority of Western governments. The question to be posed is how consistent they would be in their assistance to Ukraine if they decide consensually to stand by her. The soaring cost of living in the West compels the conclusion that there could be no guarantee that Western assistance to Ukraine, particularly in the defense and security fields, would be of a longstanding kind.

Of particular concern would be the fact that the weapons systems on offer from the UK to Ukraine could be increasingly costly to manufacture going forward. Besides they would need to be manufactured and put into action without delay.

However, these considerations should in no way deflect Ukraine’s supporters from the principled policy stance of defending her to the extent possible. Because at issue is the defense of International Law and the democratic system of government from their enemies; fascism and authoritarian rule.

While during World Wars 1 and 2 the US was with the major democracies of the West, this time around with regard to Ukraine, the US has chosen to be at cross-purposes with them. For instance, in relation to tariff matters and defense expenditure, in the NATO context, the US is pursuing a hard line which puts it at polar opposites with the West. Thus it is no longer possible to talk unreservedly of a ‘Western democratic alliance’. Put plainly, the cause of democratic development has been weakened.

A measure of relief for the supporters of Ukraine in the West could come by way of the upcoming mid-term polls in the US. If the Democratic Party fares well in them the pressure would be on the Trump administration to defer to opposition opinion at home, accommodate the best interests of Ukraine in its West European policy and perhaps even work towards a diplomatic solution to the Ukraine crisis in cooperation with Russia. Accordingly, the Democratic Party would need to put the Trump administration on the defensive, so to speak.

Until such time Ukraine’s Western supporters have no choice but to remain committed to it, ensure its steadfast defense against the invasion and work judiciously towards keeping the economic pressures at home in check.

Interestingly, at the present juncture in international politics the US could be said to be more weak than strong. For example, it has to some extent been militarily humbled by Iran; so much so it is resorting to economic means to keep Iran in check.

In keeping with this strategy, the US has launched ‘a new big wave of anti-Iran economic sanctions’ at the time of writing, aimed at cutting Iran away from all its major income sources. Some of these relate to digital assets, technology, gold, aviation and shipping. The hoped for result is the complete severance of Iran from the US dollar system.

However, while the UK and EU have no choice but to adhere to their policy of backing Ukraine, going forward they would need to dialogue more closely with the US and ensure that it cooperates with them on outstanding questions, such as Ukraine and the strengthening of democracy. The well being of the world is served when the latter aim is pursued.

Prime Minister Dr. Harini Amarasuriya opening the event

OPA 39th Annual Conference calls for Sri Lanka to move Beyond Recovery towards Sustainable Transformation

The Orgnisation of Professional Associations (OPA) successfully concluded its 39th Annual Conference, held recently at the Cinnamon Grand Colombo, under the theme “Envisioning Sri Lanka: Beyond Recovery”.

Held under the patronage of Jayantha Gallehewa, President of the OPA, with the leadership and guidance of Tisara De Silva, President-Elect and Chairman of the 39th Annual Conference, the Conference brought together leading professionals, academics, business leaders and representatives of the public and private sectors to deliberate on Sri Lanka’s next phase of national development.

The Inaugural Session, on August 2026, was graced by Prime Minister Dr. Harini Amarasuriya, as the Chief Guest; Andrew Patrick, British High Commissioner to Sri Lanka, as the Guest of Honour; and Murtaza Jafferjee, Chairman of the Advocata Institute, Sri Lanka, as the Keynote Speaker.

In her address, Prime Minister Dr. Harini Amarasuriya emphasised that overcoming the economic crisis alone should not be Sri Lanka’s ultimate objective, stressing that recovery must serve as the foundation for a broader economic and institutional transformation necessary for sustainable national progress. Reflecting on the difficult period experienced by the country, the Prime Minister noted that Sri Lanka had faced significant economic, social and institutional challenges, which had weakened public confidence and created uncertainty about the country’s future.

She stressed that “recovery only provides the foundation” and that Sri Lanka can move forward sustainably only by using that foundation to bring about meaningful transformation.

The Prime Minister observed that the theme of the OPA’s 39th Annual Conference, “Envisioning Sri Lanka: Beyond Recovery,” aptly encapsulated these national aspirations. She emphasised that Sri Lanka’s objective should not merely be to return to the conditions that existed before the crisis, but to forge a stronger national foundation characterised by robust institutions, a resilient economy, high-quality public services and an enabling environment in which every citizen has the opportunity to thrive.

She further underscored that Sri Lanka’s future development cannot be secured through economic growth and physical development alone. She emphasised that the effective mobilisation of the country’s knowledge, skills and professional expertise, is equally essential to achieving sustainable and inclusive national progress

The Technical Sessions held on 12 August 2026 brought together 19 distinguished experts and professionals representing academia, industry, banking and finance, public health, technology, management and business leadership. Their diverse expertise provided a multidisciplinary platform to examine the critical challenges, emerging opportunities and strategic choices that will shape Sri Lanka’s next phase of development, with particular emphasis on economic transformation, institutional strengthening, digitalisation, private-sector growth, human capital and sustainable development.

The deliberations were structured around four principal sub-themes: “Resilient Recovery and Sustainable Economic Development”; “Future Readiness: Innovation & Transformation”; “Policy for Impact: Advancing Equity, Sustainable Living, and National Well-Being”; and “Leadership, Governance and National Responsibility.”

Across these thematic areas, the sessions explored the structural reforms, institutional requirements and policy choices necessary to move Sri Lanka beyond economic stabilisation towards a more productive, competitive, resilient and inclusive economy. The discussions brought together diverse professional perspectives, enabling participants to examine national priorities through economic, technological, industrial, financial, social and governance lenses.

Particular emphasis was placed on the need to move beyond the diagnosis of problems towards pragmatic, evidence-based and implementable solutions. The deliberations recognised that sustainable national progress requires not only sound policies, but also effective institutions, professional competence, innovation, responsible leadership and the capacity to translate policy into tangible outcomes.

The sessions further underscored the importance of collaboration across sectors, recognising that Sri Lanka’s complex development challenges cannot be addressed in isolation. Stronger engagement among Government, private sector, professional associations, academia and civil society was identified as essential to fostering a coherent national response and ensuring that professional knowledge and expertise are effectively translated into policy and action.

Collectively, the Technical Sessions provided a substantive platform for knowledge exchange, critical reflection and forward-looking dialogue, reinforcing the OPA’s commitment to bringing the country’s professional expertise to bear on the task of building a resilient, innovative, equitable and prosperous Sri Lanka.

The OPA expressed its sincere appreciation to Prime Minister Dr. Harini Amarasuriya, the Chief Guest; Andrew Patrick, British High Commissioner to Sri Lanka and Guest of Honour; and Murtaza Jafferjee, Chairman of the Advocata Institute, Sri Lanka and Keynote Speaker, for their distinguished contributions to the Conference.

Much of what the 39th Annual Conference achieved would not have been possible without the leadership, commitment and generous contributions of Jayantha Gallehewa, President of the OPA; Tisara De Silva, President-Elect and Chairman of the 39th Annual Conference; Eng. Ravi Rupasinghe, General Secretary; Dharshana Wijemanne, Treasurer; Bhanu Wijayaratne, Convener & the Chairman of the Session Planning Committee of the 39th Annual Conference Committee, Past Presidents and Office Bearers; Presidents and representatives of Member Associations; members of the Executive Councils and General Forum; and the distinguished Session Chairmen, Resource Persons and professionals who shared their time, expertise and insights in pursuit of the Conference’s shared vision. The OPA remains immensely grateful to all those whose collective contributions enriched the 39th Annual Conference and strengthened its role as a meaningful platform for professional exchange, informed dialogue and national reflection.

‘Avurudu Musical Show 2027,’ a uniquely styled musical Avurudu celebration … Ceymphony Band style.

For Sri Lankans living 14,000 kilometres from home, the sound of home has never felt closer — and that’s thanks to one man and his band.

Since stepping into the spotlight, Gamini Hemalal and the Ceymphony Band have turned into the heartbeat of the Sri Lankan community in Toronto.

Their mission is simple: bring the music, bring the memories, bring the people together. And it’s working.

What turned out to be the talk-of-the-town was their intimate musical evening with Sri Lanka’s legendary crooner Sohan Weerasinghe.

Sohan Weerasinghe: Had
everyone on their feet at the
Angus Glen Golf Club, in
Toronto, Canada

It was a ‘full house’ long before the big date. Tickets vanished within days — demand was that overwhelming.

According to those who were there, it was a truly amazing evening. The hall was packed, the energy electric. Sohan didn’t just sing — he owned the stage.

With his velvet vocals, his charm, and that signature style, he had everyone on their feet. The ladies, especially, couldn’t get enough. No wonder they call him “The Ladies’ Man!”

One attendee summed it up perfectly:

“We had so much fun. It is truly a blessing to have our kids around us, enjoying these beautiful moments together. Thank you, Gamini Hemalal, for such a wonderful evening, with an amazing crowd and an incredible atmosphere. Your hard work and dedication truly made it a special night.

“We also need to say a big thank you to the Ceymphony Band for delivering such an outstanding performance. You all were absolutely amazing! Our entire family had a fantastic time, and we truly enjoyed every moment.

Ceymphony Band: Extremely popular in the scene in Toronto

“Wishing you all continued success. Keep up the amazing work, we can’t wait for the next.”

And the next is already on the cards: ‘Halloween Pissu Baila Party 2026,’ on Friday, 30th October, at the famous Angus Glen Golf Club.

Gamini promises a crazy night of baila, music, dancing and Halloween vibes with the Ceymphony Band. Action runs from 8:00 PM to 12:00 midnight, with plenty of prizes to be won.

Gamini Hemalal: Amazing work for the Sri Lankan community,
in Toronto, Canada

Gamini is also putting together a special event, connected with the 2027 Avurudu celebrations — ‘Avurudu Musical Show 2027,’ a uniquely styled musical Avurudu celebration … Ceymphony Band style.

It’s scheduled to be held on Saturday, 10th April, 2027, also at the Angus Glen Golf Club.

Through music, Gamini Hemalal and Ceymphony are doing what diaspora bands do best — they’re shrinking the distance between two worlds.

One baila beat at a time, one full house at a time, they’re making sure that even in Canada, Sri Lankans feel like home.

Yes, there is plenty of action, indeed, for the Sri Lankan community in Toronto, Canada.
