Yasantha Rajakarunanayake is a Sri Lanka-born American mathematician, technologist, researcher, professor and data scientist. He is best known for befriending Amazon CEO Jeff Bezos who was his classmate at the Princeton University. He was also widely acknowledged for having assisted Bezos in solving a tough, tricky mathematical problem and he also received social media fame and widespread attention for having sought the mathematical problem for Bezos.

Biography

Yasantha grew up in the suburb of Colombo, in Ratmalana. He grew up with humble beginnings and hails from a middle-class family. His mother Ethel Rajakarunanayake served as a school teacher at St. Mary's College in Dehiwala. His father, Hilary Rajakarunanayake, served as an accountant in the Middle East region. His father also spent a short stint working at Daily News as its Deputy Editor before his retirement.

He attended the Royal College in Colombo and he made a name for himself by excelling in academic studies. Notably, he was a batch top at his school and he managed to receive the highest marks in the GCE Advanced Level Examination in the Combined Mathematics stream by obtaining satisfactory results of 4A's. He subsequently passed out from his school with flying colours.

He suffered from bad asthma since his childhood and his father advised him to find a well maintained air conditioned office so that he does not have to breathe dusty air while working. Yasantha took his father's advise seriously and began focusing on making a career in IT field.

Career

He pursued his higher education at the University of Moratuwa in the field of electronic engineering, which he had to stop halfway through as an opportunity to get enrolled in a prestigious university like Princeton University came knocking on the door, and it was hard to forgo for Yasantha. He eventually received a scholarship offer to attend Princeton University, which he himself considered his dream while growing up. He left Sri Lanka in 1982 to pursue his undergraduate education at Princeton University. The stars aligned for him at Princeton University when he also happened to coincidentally meet Jeff Bezos, who later went on to become the chief executive officer at Amazon.

Bezos was impressed with the work ethic and professionalism of Yasantha and Bezos even called him the "smartest guy at Princeton". On 13 September 2018, during a talk at The Economic Club of Washington, D.C., Bezos heaped praise on Yasantha indicating that Yasantha was the brightest and smartest person to have ever been seen at Princeton University.

Bezos, during the talk, further revealed that Yasantha had defeated him to solve a mathematical problem and as a result, Bezos himself admitted that he gave up his dreams of becoming a theoretical physicist. Bezos and Yasantha, though, had not maintained a close connection after the college days, as both lost touch owing to busy schedules and both moved into different career pathways. Soon after Bezos had mentioned Yasantha's name in the September talk, people apparently went to search about him in the internet and several of them even sent emails and text messages to reach out Yasantha. Yasantha revealed that most of the mail messages from anonymous persons repeatedly asked whether "Are you Jeff Bezos’ Yoshanta’?" Yasantha confirmed that he received spam emails in his LinkedIn inbox, as he initially had cast doubts and suspicions about whether someone had hacked his email.

He successfully completed his undergraduate studies as an Electrical Engineering and Computer Science major in 1985. He obtained his Doctor of Philosophy in the field of Applied Physics at California Institute of Technology. He worked for few years as a university professor in Physics and he established his reputation with over 50 technical publications to his name before switching career trajectory into internet technology in 1995 after being aware about the potential of Broadband internet. He has been serving as a senior technologist and scientist with a vast experience spanning three decades. As of August 2019, he reportedly had about 94 US patent applications for his inventions which also included pending applications prior to approval. He created several innovative applications and Artificial intelligence algorithm designs for human presence and gesture detection with mmWave radar systems. He also stamped his authority further by developing and designing systems algorithms that could leverage AI in novel MedTech and medical imaging applications. He successfully implemented and improved techniques and methodologies that could improvise and enhance medical diagnosis. He has also immensely contributed to several basic fundamental technologies of the Internet and Mobile ecosystem during his illustrious career as a high tech scientist and researcher. He also went onto serve as senior director for Taiwanese semiconductor firm MediaTek.
