Molecular modeling and simulation can provide crucial insights into the structure, dynamics, and interactions of various systems at the molecular level, to both complement and enrich experimental measurements. Computational and Modeling Core of the UMass Institute for Applied Life Sciences (IALS) provides expert consultative and collaborative services to both academic and industrial partners. As a collaborative partner, we contribute directly to research and development, such as performing simulations, interpreting results, providing actionable decisions, and preparing materials for scientific manuscripts and grant applications. We also assist scientists who are unfamiliar with computational tools and high-performance computing to apply these techniques in their research projects. Our expertise includes ab-initio/classical molecular dynamics simulations, quantum chemistry/electronic structure calculations, computational spectroscopy, small molecule design, and protein-ligand docking and screening.

Li-Jun Ma, PhD
Dr. Ma received her PhD in Molecular Biology from the State University of New York. She is currently an Associate Professor in Department of Biochemistry and Molecular Biology in University of Massachusetts, Amherst. Her lab studies genetic mechanisms that sustain structural and functional flexibility while maintaining the integrity of the organism using the model fungal system Fusarium oxysporum. Specifically, Specifically, her research combines experimental and computational biology approaches to study the molecular interactions within the genome and between the “core genome” and the horizontally transferred chromosomes, to investigate the plant-fungal interactions using a Fusarium-Arabidopsis pathosystem for the development of optimized management strategies to control the Fusarium vascular wilt diseases; and to dissect virulence factors that contribute to emerging infectious disease using Fusarium-animal model systems for the development of novel therapeutics.
Craig T. Martin, PhD
Dr. Martin obtained his PhD in Chemistry from California Institution of Technology. He is currently a Professor in Department of Chemistry in University of Massachusetts, Amherst. The overall goal of his research is to understand the chemical and enzymological basis of complex and fundamental processes in biology. His research group combines the powerful quantitative tools of biophysical chemistry with equally powerful techniques found in modern molecular biology to provide detailed information on specific chemical interactions in enzymology.
