Amitabh Varshney is a professor of computer science and director of the University of Maryland Institute for Advanced Computer Studies.

Varshney's research focuses on exploring the applications of graphics and visualization in engineering, science, and medicine through advances in geometry processing, illumination models, perceptual rendering, and high-performance visual computing. His research results are being used in a variety of application domains such as therapeutic drug design, climate modeling, plasma physics, nano manufacturing, medical imaging, and gene sequencing.

Varshney has worked on the design and implementation of virtual walkthroughs of proposed structures, such as buildings, automobiles and submarines. His research in molecular graphics has involved devising new algorithms for parallel and analytical computation and visualization of molecular surfaces, their interfaces, and electrostatics.

Varshney has also contributed toward the development of new algorithms for a number of research areas in graphics and visualization including visual saliency, summarization of large visual datasets, automatically generating multiresolution hierarchies, procedural textures, and rendering with points, images, meshes, and volumes. He is currently exploring several applications in general-purpose high performance parallel computing using clusters of CPUs and Graphics Processing Units (GPUs). He has consulted and collaborated with NVIDIA, Honda, IBM, Daimler Chrysler, General Dynamics, and Reuters.

Varshney received a National Science Foundation (NSF) CAREER Award, given to outstanding junior faculty who exemplify the role of teacher-scholars so they can further their research in their areas of expertise, in 1995 and the IEEE Visualization Technical Achievement Award in 2004.

He was elected as a fellow of the IEEE in 2010. He is the director of the NVIDIA CUDA Center of Excellence at UMD and serves as the chair of the IEEE Visualization and Graphics Technical Committee.

Varshney received a B. Tech. in computer science from the Indian Institute of Technology, Delhi in 1989 and an M.S. and doctorate in computer science from the University of North Carolina at Chapel Hill in 1991 and 1994.
