Research

I work on computational geometry algorithms for the GPU. I am advised by Prof. Tan Tiow Seng.

Automatic PSF Estimation for Coded Exposure
A technique for automatic estimation of the Point Spread Function (PSF) using a coded exposure camera. The camera was simulated in Matlab. The project presentation is here [PDF].
Rigid Body and Fluid Interplay Solver
A solver that can simulate the interaction between an enclosed fluid and rigid bodies introduced inside it. The solver was implemented in Cg utilizing the parallel processing capabilities of the GPU. The presentation is here [PDF].
Karya
A stack based CPU emulator that accepts postfix expressions. The expressions converted into tagged instruction bundles using a hardware tagging unit. The bundles are scheduled for execution using a scoreboard of registers and execution units. The project was implemented as part of the CS5222 course.

In the current semester (Sem 2, AY 2010-2011), I am a full-time teaching assistant for the course CS3215 (Software Engineering Project). For updates, please see my CS3215 blog.
I tutored 5 teams of students in CS3215 (Software Engineering Project) during Sem 1, AY 2010-2011. The teaching feedback given by my students can be seen here [PDF].
I tutored 2 batches of students for their lab sessions in CS3241 (Computer Graphics) during Sem 1, AY 2008-2009. Feedback from my students is here [PDF].
I tutored 2 batches of students in CS1101C (Programming Methodology In C) during Sem 2, AY 2006-2007. Feedback from my students can be seen here.
