I am a graduate student in the Department of Physics, Michigan Technological University since fall 2007. I work under the guidence of Dr. Ranjit Pati. Before joining MTU, I obtained my Masters of Science in Physics from Indian Institute of Technology (IIT) Madras in 2007 and Bachelor of Science degree with Physics Honors from Scottish Church College, under the University of Calcutta (India) in 2005.
My research is focused on understanding some of the open issues in quantum transport in nanoscale devices that exploit electron's charge and spin degrees of freedom. Based on the density functional theory, my research primarily deals with modeling of different nanoscale materials for the use of new generation electronic devices. The devices we model in our research, are mainly made of single molecules, semiconducting and metallic nanowires and nanotubes. These atomic scale devices exhibit interesting features like negative differential resistance, phase transition, spin valve effect. Thus, it opens up ample opportunities for the theoretical physicists to investigate the materials at the scale of atoms and electrons. Being actively involved in this area, we particularly try to answer the questions, which not only help in understanding fundamental science in the atomic scale but it can also help experimentalists to design the devices. Through our studies, we investigate different possible ways to control some of the important characteristics of these materials and try to look for some generalized model that would explain different observed phenomena.
Besides Physics, I enjoy Photography very much. Few months after I landed in the beautiful Upper Peninsula in the northern Michigan, I started capturing nature in my camera. Unconditionally, this hobby became a passion. Through my lens, I try to explore the natural beauty and wilderness of upper Michigan. You can get a flavor of it in my Photography section.
