Keith Cassidy

Keith Cassidy is an Assistant Professor in the Department of Physics at the University of Missouri, where he leads the Cassidy Research Lab focused on Biological Physics. His work integrates computational techniques to study biomolecular systems, particularly the signal transduction mechanisms in bacterial chemosensory arrays.

Education:

• PhD in Physics from the University of Illinois at Urbana-Champaign

Research Interests include molecular dynamics simulations, protein structure modeling, and computational biophysics of bacterial chemotaxis. His lab employs multi-scale simulations and collaborates with structural biologists and biochemists to connect computational models to cellular behavior using cryo-electron tomography and hybrid modeling approaches.

Recent Publication Trends highlight his focus on:

• Integrative structural modeling combining simulations and cryo-EM
• Signal transduction mechanisms in microbial systems
• Protein-lipid interactions in membrane complexes
• Software development for biophysical analysis (e.g., PyLipID)
• Dynamic organization of chemosensory arrays
• Environmental microbiology applications

Laboratory: The Cassidy Lab develops computational frameworks to explore biomolecular dynamics, bridging atomic-level simulations with cellular-level observations.
