Dr. Bajaj is the Computational Applied Mathematics Chair in Visualization, professor of computer science, and director of the Center for Computational Visualization at the Institute of Computational Engineering and Sciences. Bajaj's research areas of interest include Image Processing, Computational Geometry, Geometric Modeling, Computer Graphics, Data Analysis, Visualization, Computational Biology, Bioinformatics, and Computational Mathematics. Current research topics include the design and development of efficient and robust 2D/3D/4D image and geometry filtering,
reconstruction, compression, matching and meshing algorithms. He applies these algorithms to (a) the structure elucidation and construction of multi-scale domain models of molecules, organelles, cells, tissues and organs from multi-modal, microscopy and bio-imaging and (b) a fast high-dimensional search and scoring procedure for identifying energetically favourable binding of proteins with bio-compounds (virtual screening for anti-viral drugs). He is also involved in developing integrated approaches to computational modeling, mathematical analysis and interrogative visualization, especially for dynamic bio-medical structures and phenomena.
