About
I am a research scientist jointly at NASA’s Goddard Space Flight Center and the University of Maryland Baltimore County. I led several NASA R&D projects and founded the Goddard Lunar Data Analysis Center. I am an expert in the high-precision modeling of dynamic physical systems, and I use various tracking data like laser, radio, images, and their derivatives to optimize these models.
Research interests
Dr. Vishnu Viswanathan’s research is focused on the analysis of tracking data to determine geophysical, orbital and rotational properties of planetary bodies.
