Welcome to my homepage! I run the UCSB MIRAGE Lab to research in computer graphics, imaging, visualization, and computer vision. I graduated with a Ph.D. in Electrical Engineering from the Graphics Lab at Stanford University, where my adviser was Pat Hanrahan.

Mini Biography

Pradeep Sen is an Associate Professor in the UCSB MIRAGE Lab in the Department of Electrical and Computer Engineering at the University of California, Santa Barbara. He attended Purdue University from 1992 - 1996, where he graduated with a B.S. in Computer and Electrical Engineering. He then attended Stanford University where he received his M.S. in Electrical Engineering in 1998 in the area of electron-beam lithography. In 2000, he joined the Stanford Graphics Lab where he did research on real-time rendering and computational photography. He received his Ph.D. in Electrical Engineering in June 2006, advised by Dr. Pat Hanrahan. His research interests include algorithms for image synthesis, computational image processing, and computational photography, and he is a co-author of over 50 technical publications, including more than ten SIGGRAPH/SIGGRAPH Asia/ToG publications. Dr. Sen has been awarded more than $2.2 million in research funding, including an NSF CAREER award in 2009.

Selected Awards/Honors

Research Interests

My research interests are in the area of rendering/image synthesis and computational image processing. I study novel rendering algorithms to accelerate global illumination, as well as image-based techniques for capturing light transport. I am also interested in real-time rendering and graphics hardware. On the computational image processing side, I am interested in novel imaging architectures as well as new ways to combine processing and acquisition to capture new kinds of imagery.

Current Students

At UCSB, I have the pleasure of working with many great graduate students:

I am also looking for a several more Ph.D. students who are interested in computer graphics, computer vision and image processing. If you want to work in these areas of research, applications can be found here.
