Current Research

Our current research focuses on applying computations to solve problems in predictive toxicology and further the field of safer chemical design. Chemicals and materials created through advanced chemistry are the basis of our society and our economy. Yet, with all of the excellent toxicology that has helped us understand and in some cases predict toxicity  associated with industrial chemicals, little progress has been made in answering the fundamental scientific questions that would allow for the design of chemicals with reduced hazard to humans and the environment. The potential threat that commercial chemicals can pose to our society and the environment through unintended biological activity has become  increasingly clear in recent years. Our group focuses on translating the advances made in computational chemistry, and specifically computer­aided drug discovery, to the design of safer chemicals. The goal is to be able to design new (or re­design exisiting) chemicals in such a way that minimizes their biological activity while maintaining desired function. We employ sophisticated modeling techniques, such as quantum and statistical mechanics using free  energy perturbation calculations, to better understand key intermolecular interactions in various  toxicity pathways, such as skin sensitization, mutagenicity, AChE inhibition or oxidative stress.
