Janardan's research interests are focused in geometric computing and applications. Broadly speaking, geometric computing is concerned with the design of efficient computational techniques for representing, reasoning with, and manipulating geometric entities. His research here encompasses algorithm and data structure design and analysis, software development, and deployment of solutions into applications. Application areas of current interest include computer-aided design and manufacture, biomedical simulation and modeling, geometric computing under uncertainty, and spatial query processing. To get a flavor for some of this, check out some of his work on layered manufacturing (a.k.a. 3D-printing) here.
