Welcome
Welcome to the Soft Matter Interfaces and Energy Laboratory in the Department of Mechanical Engineering, University of Maryland, headed by Dr. Siddhartha Das. The main research focus of the group is to devise new theoretical and numerical models to explain different fascinating physical phenomena related to soft matter and interfaces. Our research endeavour range from better understanding the colloidal dynamics in an ubiquitous drying coffee drop and the response of an elastomer to surface tension forces to pinpointing the interplay of rheology and electrohydrodynamics in relevant biophysical and micro-nanofluidic problems. The group is also involved in extensive collaborations in several projects with strong experimental components — the main focus of the group for such problems is to clearly identify and hypothesize the central phenomena dictating the experimental observations.
