Research Description: Most of my research work has been in quantum many-body techniques and nanophysics. I am studying problems where strong electron-electron interactions dominate the physical properties of nanostructures such as quantum dots, wires, and rings. Experimental accessibility of such structures provides a crucial testing ground for many important concepts of nanoscopic and many-body physics.

Advanced computational techniques such as quantum Monte Carlo and configuration interaction methods are necessary for accurate calculations on strongly interacting systems. By combining these "exact" methods, and using other numerical techniques such as Keldysh Green's functions formalism, density-functional theory, and Hartree-Fock equations as complementary tools, we are studying physical properties such as electronic structure and transport properties.

My earlier work was on calculation of quantum transport properties of quantum dots using Keldysh Green's function formalism, and photoluminescence, electronic and transport properties of multiple quantum well structures, using a bipolar semiclassical Monte Carlo method.

I am a postdoctoral fellow with Harold Baranger at Duke University. Our goal is to develop quantum Monte Carlo methods to study electronic and transport properties of nanostructures.
