Research: I have worked in, roughly speaking, two areas relating to Computers: Graphics, and Vision along with my students and staff. Follow this (sorry, old, dated) for some papers. Check out some of my (again older) talks too if you have time. You may also want to look at some infrequently updated publications, and the aforementioned talks and papers (check out the abstract to figure out what is going on).

Teaching: I am teaching Math for Visual Computing (MVC) this semester. Please note that this course is strictly for entering post graduate students, and is not available for students with undergraduate preparation in (currently or earlier from) the older IITs.

Courses I have offered in the past include (all course notes work under the Creative Commons model): CS101: Basic freshman programming , Software Systems, Parallel Programming Paradigms (PPP), Math for Visual Computing, Graphics I, Multimedia Systems, Computer Vision, Digital Image Processing, Graphics II, Digital Signal Processing, Algorithms, Spatial Data Structures, Multimedia (in distance mode), and (in the era when HTML did not exist) Data Structures and Algorithms, and Advanced Computer Graphics.
