Dr. Siddhartha Das, FRSC joined the Department of Mechanical Engineering, University of Maryland, College Park in March, 2014. He was promoted to Associate Professorship (with tenure) in August 2019. Dr. Das received his Ph.D. from the Indian Institute of Technology Kharagpur in 2010 in the area of theoretical microfluidics. Following his Ph.D., Dr. Das joined the Physics of Fluids Group in University of Twente, the Netherlands as a Postdoc and worked on surface nanobubbles, capillarity and soft wetting. After his stint in the Netherlands, Dr. Das went for his second Postdoc in the Department of Mechanical Engineering, University of Alberta, Canada. In Alberta, Dr. Das was honored with the Banting Postdoctoral Fellowship, the most prestigious postdoctoral fellowship of Canada.

Dr. Das' research interests span different areas of micro-nanoscale fluid mechanics and interactions of soft matter and complex interfaces with fluid mechanics. He is particularly interested in understanding issues such as the wetting of a soft solid, electrohydrodynamics past a soft interface, evaporation-mediated self-assembly of soft and rigid particles, mechanics of complex fluids during 3-D printing, interactions of liquid with 2-D materials like graphene and hexagonal Boron Nitride, micro-nanoscale water transport in trees, etc.

Dr. Das has authored 132 journal publications (as of December 2019), including publications in such prestigious journals as Nature Materials, Proceedings of the National Academy of Sciences USA, Nature Communications, Advanced Materials, Energy and Environmental Sciences, Advanced Functional Materials, Advanced Energy Materials, Journal of the American Chemical Society, ACS Nano, Physical Review Letters, Physical Review E, Physics of Fluids, Journal of Fluid Mechanics, Soft Matter, Journal of Chemical Physics, Journal of Physical Chemistry, Journal of Applied Physics, and Scientific Reports.
