Trivia

Before making Ph.D., I used to program a lot of programs and tools and create cool 3D tracks (1 and 2) and cars for a game called Re-Volt. I also used to make a lot of add-ins and features in PHP/JQuery/Javascript/CSS/HTML in the now-defunct Re-Volt Live forum. Now I make cool research papers, too.
