My research interests are in areas of computer graphics concerned with using computers to produce realistic images (photorealistic images). Specifically, I am interested in how to represent interesting natural phenomena like diffraction which produces the color streaks we observe when we look at a CD-ROM and interference which produces color in oil slicks and soap bubbles.

I am also interested in an emerging area of computer graphics known as appearance models. This area tries to introduce effects like weathering of stones and aging of paint pigments to make computer graphics images even more realistic while reducing the almost plastic look of previous models.
