Introduction
I am a graduate student in physical chemistry and scientific computing at the University of Michigan. My current research is on the quantum dynamics in light-harvesting systems using a combined approach of Ehrenfest dynamics with a modified version of the Generalized Quantum Master Equation. I have an M.S. in chemical engineering from Cornell University where I worked with Dr. Paulette Clancy on determining the relationship among the unit cell parameters of 6,13-TIPS pentacene, its energy profile, and its various polymorph configurations.

The generalized quantum master equation (GQME) provides a general and formally exact framework for simulating the reduced dynamics of open quantum systems. The recently introduced modified approach to the GQME (M-GQME) corresponds to a specific implementation of the GQME that is geared toward simulating the dynamics of the electronic reduced densit...
Determining the Effects of Unit Cell Parameters and Solvent Size on the Energy Profile of Organic Semiconducting Crystals

Organic semiconducting materials are gaining popularity as solar cell materials, in large part because of their ab...
Understanding crystal polymorphism is a long-standing challenge relevant to many fields, such as pharmaceuticals, organic semiconductors, pigments, food, and explosives. Controlling polymorphism of organic semiconductors (OSCs) in thin films is particularly important given that such films form the active layer in most organic electronics devices an...
A crystal's structure has significant impact on its resulting biological, physical, optical and electronic properties. In organic electronics, 6,13(bis-triisopropylsilylethynyl)pentacene (TIPS-pentacene), a small-molecule organic semiconductor, adopts metastable polymorphs possessing significantly faster charge transport than the equilibrium crysta...
