Amartya Sengupta - About Me
During my graduate studies at Rutgers University and NJIT, I had extensively used ultrafast optical methodologies to generate terahertz radiation to study defect states in semiconductors, high energetic materials and scattering from granular materials.
After that, I worked in two different post-doctoral positions: At the University of Leeds, UK on the development of portable sources and detectors of THz radiation for a year before moving to Washington State University, USA to work exotic states of the "greenhouse gas", CO2 at extreme conditions of pressure and temperature for carbon sequestration applications and for understanding the composition of the earth's core.
Currently, I am working at Princeton University in the Dept. of Geosciences as an Associate Research Scholar with Thomas Duffy.
My current research interest revolves around the understanding of the changes of physical properties of condensed matter systems and minerals under extreme conditions using different spectroscopic techniques such as Raman spectroscopy and Brillouin spectroscopy. Currently, I am exploring the reaction mechanisms of various transitions of different minerals to understand the various aspects of the formation and composition of the earth. I am also actively involved in the NSLS at the Brookhaven National Lab to develop the laser heating instrumentation for high P-T experiments.
