Yevin Goonatilake hasn’t slowed down since becoming George Mason �鶹����’s youngest graduate with a 4.0 in December. In fact, he’s only picked up speed.����

Now 16, the Leesburg, Virginia, native has added another milestone to his remarkable journey—completing a , making him the youngest person in university history to do so.

Along the way, Goonatilake landed a job, earned his learner’s permit, and continued playing professional cricket—all while finishing graduate classwork that would challenge even seasoned scholars.

“Graduate life has definitely been a lot busier and more challenging,” he said. “These last few months have been the most demanding yet.”��

Enrolled in the through the , Goonatilake appears on track to finish his master’s with the same 4.0 GPA he held as an undergraduate.

“I’m proud to hold onto the record for the time being,” he said. “I’m sure it will be broken in the future, but it’s nice to be George Mason’s youngest ever master’s graduate for now.”

Taking four graduate courses this semester—including three advanced-level classes—meant longer hours and greater expectations. But Goonatilake has proven he’s up for the challenge of graduate study.

“One of the biggest differences I noticed in the graduate program is that it requires more independence,” he said. “The specific implementation details are often left to you. The focus shifts from following set instructions to producing meaningful results.”

His academic interests have sharpened, too. He’s especially drawn to cryptography, which involves applying encryption and decryption schemes to messages in order to conceal them.

As a master’s student research assistant, Goonatilake is working with Computer Science Professor and Eminent Scholar on cutting-edge research at the intersection of cryptography and large language models (LLMs). His current focus: cryptographic watermarking—embedding hidden signals in artificial intelligence (AI)-generated content to identify its source.

Ateniese said he was “quite astonished” upon learning Goonatilake’s age.

“But age aside, I’m impressed by his maturity, diligence, and ability to grasp extremely complex topics,” he said. “I’m delighted to have him on my team, and I have no doubt that he will continue to achieve remarkable success.”

Despite a demanding schedule, Goonatilake remains committed to cricket, playing for the , part of Minor League Cricket. He trains several times per week and played in winter tournaments this past year in both Tampa and Miami.

“Balancing academics and cricket has kept me a little busier than I would prefer,” he said. “But I need both. Cricket keeps me grounded and gives me the outlet to clear my mind, giving me something to look forward to outside of academics.”

Celebrating his 16th birthday earlier this year has made that balancing act a little easier: with a learner’s permit in hand, Goonatilake is beginning to practice driving. “Now that I have my permit, I have been trying to drive whenever I can,” he said with a smile.

As for what’s next? Goonatilake hopes to remain at George Mason in the fall to pursue a PhD in computer science.
