Dr. Shanti Bhattacharya joined the Department of Electrical Engineering in the year 2005. At that time, her group worked mainly in the design, development, and fabrication of novel diffractive optical elements, fiber-based interferometry, and optical MEMS. Her areas of research have now expanded to include complex light generation and diffractive metasurface design and fabrication.
