Research in Molecular Biophysics

The Straub Group investigates fundamental aspects of protein dynamics and thermodynamics underlying the formation of protein structure, through folding and aggregation, and enabling protein function, through pathways of energy flow and signaling.  Student and postdoctoral research scientists in the Straub Group work to develop and employ state-of-the-art computational methods while working in collaboration with leading experimental research groups.

    Amyloid-β (Aβ) protein biogenesis

  • Kinetic and thermodynamic properties defining protein aggregation are elucidated through pioneering computational studies of the earliest stages of amyloid protein aggregation including amyloid protein biogenesis.
  • Novel computational algorithms for enhanced sampling of conformational ensembles in complex biomolecular systems are developed for global optimization and enhanced conformational sampling in complex molecular systems.
  • The role of membrane heterogeneity in protein structure and function is explored to elucidate its role in membrane protein function and protein aggregation. Professor Straub’s book, Proteins: Energy, Heat and Signal Flow, co-edited with David Leitner, captures the state-of-the-art in theoretical studies of protein dynamics and signaling.

Textbook for Undergraduate Mathematical Methods

Mathematical Methods for Molecular Science

Version 1.0 (August 2019)

It is widely acknowledged that the traditional calculus sequence required of most molecular science majors, consisting of a year of differential and integral calculus and possibly a semester of multivariate calculus, does not provide the mathematical background needed for success in the quantum mechanics and statistical thermodynamics courses that follow.

The textbook Mathematical Methods for Molecular Science is designed to support a one semester course that builds on the introductory calculus sequence and covers critical topics in multivariate calculus, ordinary and partial differential equations, and linear algebra. Published through a Creative Commons license, the full textbook is available for download.
