For the first time in its 168-year history, the University of Melbourne has awarded simultaneous PhDs to identical Sri Lankan twins.

The Melbourne University has said in a media statement that Nadeesha and Thejani Gunaratne commenced PhDs with the University, in 2016, following studies in Food Science and Technology at the University of Sri Jayewardenepura in their home country of Sri Lanka.

Both received their doctorates on Saturday 17 December in Melbourne, one day before International Twins Day.

During their PhD, both twins researched new ways to measure and analyse consumers’ emotional and sensory responses to chocolate in complementary research, with Thejani focusing on the impact of chocolate flavour and Nadeesha on the impact of packaging.

According to the University of Melbourne, their PhD research topics were:

Nadeesha Gunaratne – Implementation of non-invasive biometrics to identify effects of chocolate packaging towards consumer emotional and sensory responses

Thejani Gunaratne – Development and implementation of novel sensory evaluation procedures of consumer acceptability towards chocolate, based on emotions and biometric responses.

Their graduation ceremony was originally planned for March 2020 but delayed due to the pandemic.

Thejani is now a Senior Experimental Scientist – Sensory and Consumer Science at CSIRO in Melbourne and Nadeesha is a Research Scientist – Sensory and Consumer Products at Amway in Los Angeles.

“Being born twins, we have a unique bond that’s hard to explain to other people,” Thejani said.

“The fact that we have completed all important milestones together, primary school, high school and now university, has made our lives even more enjoyable. We were eagerly waiting to attend the PhD graduation together as it means a lot to us.”

Although the twins now live on opposite sides of the world, Nadeesha says they’re closer than ever.

“We still talk multiple times a day whether it’s by text, over the phone or on Zoom,” she said. “The fact that we’re finally together and were able to graduate together in person is a dream come true for both of us and our family.”

Under the supervision of Professor Frank Dunshea, Associate Professor Sigfredo Fuentes and Dr Damir Torrico, during their individual PhDs, the twins used technology developed in the University of Melbourne’s Sensory Lab, to apply biometrics – including skin temperature, facial micro-expressions and heart rate – to develop machine learning models and an evidence-based understanding of how consumers respond to both chocolate and its packaging, consciously and unconsciously.

They achieved seven academic journal publications in their PhDs, all with both twins as co-authors.

Their research highlights that our enjoyment of chocolate products and other foods – and our decisions to purchase them – are driven by far more factors than taste alone.

“When we buy food, based on its packaging and labels, we expect it to both taste good and match what that packaging tells us,” Nadeesha said.

“In the past, sensory research relied heavily on what participants said or did, which provides useful information on how consumers consciously respond to products, but limited on scientific data such as unconscious and emotional responses, which have a major impact on their experience and whether they’ll buy the same product again.”

Professor Dunshea said the biometric techniques, applied by Nadeesha and Thejani in their research, at the University, has added to our ability to conduct data-based sensory science research in recent years.

“For the food industries, particularly small and medium-sized enterprises, in Australia, with an export focus, this allows greater certainty that new foods will appeal to consumers and are more likely to result in repeat purchases. For consumers, it means more enjoyable foods that live up to the promise of what the packaging communicates,” Professor Dunshea said.

Prime Minister Dr. Harini Amarasuriya attended the special ceremony marking the 40th anniversary of the Sri Lanka Nippon Educational and Cultural Centre (SNECC), along with the 75th birthday of its Secretary General, the Chief Incumbent of Sri Mahindaramaya, Ethul Kotte, the Chief Sangha Nayake of the Western Province, and scholar Ven. Meegahathenna Chandrasiri Thero.

The primary objective of the event was to appreciate the service rendered by the Sri Lanka Nippon Educational and Cultural Centre, which has functioned as a bridge between Japan and Sri Lanka since 1986, contributing significantly to the development and welfare of children in Sri Lanka.

Addressing the gathering, the Prime Minister stated that the social service carried out by Ven. Meegahathenna Chandrasiri Thero through the Nippon Centre, aimed at fulfilling the educational aspirations of Sri Lankan children, is highly commendable. She further emphasized that the Centre’s contribution to nurturing skilled children into disciplined and responsible citizens, as well as strengthening cultural ties between the two countries, is appreciated by the Government.

Over the past four decades, thousands of students have benefited from the “Nippon Scholarship” programme implemented by the Centre. In addition to providing school supplies, monthly financial assistance, medical support, and spectacles, the programme offers Japanese language education and guidance for employment and training opportunities in Japan for Sri Lankan youth. Annual study tours to Japan and collaborative programmes organized to enhance mutual understanding between students of the two countries were also highlighted at the event.

Marking this special occasion, the Prime Minister extended her best wishes to Ven. Meegahathenna Chandrasiri Thero on his 75th birthday and wished him continued strength to successfully carry forward this invaluable service.

The event was attended by the Mayor of Kotte, Arosha Atapattu, representatives of sponsoring organizations from Japan, scholarship recipients, and other distinguished guests.

The Offshore Patrol Vessel P 628, which was formally handed over to the Sri Lanka Navy by the U.S. Coast Guard in December 2025, departed for Sri Lanka from Baltimore, United States on 20th February 2026. The home bound journey began, after the modernization work of the ship to suit the operational needs of the Sri Lanka Navy.

The EX-United States Coast Guard Cutter, USCGC Decisive was officially handed over to the Sri Lanka Navy on 02 Dec 25, as the latest addition to the SLN fleet under the Pennant Number P 628. Upon her arrival in Sri Lanka, the ship is scheduled to be formally commissioned into the fleet.

Measuring 64 metres in length, this ‘B-Type Reliance Class 210-foot Cutter’ is equipped with advanced technological systems and facilities, capable of conducting extensive surveillance operations spanning up to 6,000 nautical miles per patrol.

The vessel’s voyage to Colombo is historic, possibly marking the longest-ever passage undertaken by a Sri Lanka Navy ship. Covering approximately 14,775 nautical miles, the journey will see the P 628 navigate from Baltimore through the Atlantic Ocean, the Panama Canal (a first for a Sri Lankan naval vessel), the Pacific Ocean, and into the Indian Ocean via the Straits of Malacca. The ship is expected to arrive in Sri Lanka during the first week of May 2026.

During the transit, the P 628 is scheduled to make port calls to replenish supplies and services, providing opportunities to further strengthen diplomatic ties with partner nations.

This transfer represents the fourth vessel provided to the Sri Lanka Navy by the United States Coast Guard, reinforcing a long-standing partnership aimed at addressing common maritime challenges.
