Career History: Dr. Jayasekera joined the Department in the Fall of 2011. She graduated with a Ph.D. from the University of Oklahoma, with Prof. Kieran Mullen and Prof. Michael A. Morrison. She did her postdoctoral work with Prof. J. W. Mintmire at Oklahoma State University, and with Prof. M. Boungiorno Nardelli and Prof. K. W. Kim at North Carolina State University.
Research: Dr. Jayasekera's research expertise/interests are in engineering electron structure, electron transport and heat transport in low-dimensional nanostructures for device applications. Most of her recent work are based on ab-initio calculations. Her current/recent work involves electronic band engineering of graphene related systems, and investigating thermal transport in oxide based nanostructures for thremoelectric applications. Visit the research page for more details.
Teaching: Her teaching materials are maintained in a webpage "Physics and Fun with Clicks". This page is frequently updated as she develops new materials.

One summer night, when I was living in Stillwater, Oklahoma, my mind started flashing back in time with a pen in hand; This happens rarely: though my mind frequently flashes back in time, my pen does not move as my mind roams around. Here I am sharing my thoughts from Summer of 2006.
I was born and brought up in a small village in Sri Lanka, a beautiful island in the Indian Ocean. My father used to teach at high school and my mother took care of us. I have two brothers. My grand parents were with us and passed away several years back. You know... When you move with grand parents, so many rules. my grand mother was very nice but, she was very strict. My grand father was one of the nicest individuals I have seen ever.
I can't believe that my parents are now grand parents of three little ones. I have two beautiful nieces and two cute nephews. (Sounds like I cant count... Not really, one nephew is from my cousin sis...)
Thanks to the free education system in Sri Lanka, I had my education all for free until I graudate with my first degree. I had my primary education in a high school in the nearby village: Batepola Maha Vidyalaya, which is around 20 minuites walk from my home. We, a bunch of kids used to walk this distance with a lots of fun. Absolutely a wonderful time!!! After 4 years, I entered to Gothamy Primary School, Gampaha, one of the best primary schools in the island. I was there until I was selected to enter Devi Balika Vidyalaya, Colombo, one of the top girl's schools in the nation.
I always liked mathematics. But I was never studious. In Sri Lanka, it was not easy to enter the university. Due to the limited faciliteis, university entrance exams were very competitive. Thanks to my family, teachers and friends (they did encourage me), I managed to enter to study fundamental sciences in University of Peradeniya. This is a wonderful place...for studies and also for fun!!!
I really like Physics and Chemistry both. I enjoyed learning both the subjects at the University. My brother made me moving more towards Physics. I fell in love with Physics since then... I won several awards. Remarkable!!!!!, That was the first time I managed to be the first where I was awarded with the Appapillai Prize. I graduated with a first class honors.... I was so happy, My family and every one close to me were so proud of me. I chose to come over seas to continue my education. I enterd OU in the Fall of 1999. There I became the outstanding first year graduate student and was awarded with Lin Fellowship. (Yeh... I was again first....)I won several other awards as well. To learn about my academic side at OU, please visit my research page. I defended my Ph.D in 2005 September.
After my graduation, here I am now... working as a postdoc in the Oklahoma State University. Almost always, you can find me staring at the computer or reading books.....................
No No...Not always...I do enjoy a lot. I like traveling (especially road trips), spending time with my friends and my family, chit-chatting with people (a lot), watching TV .... I also do enjoy driving. (Surprising aha for all those who know how I learnt). Please visit my photo album page to read about my traveling............. If you are Curious !!!....
Thanks for being curious and reading my thoughts...
