Yuba Dahal (Assoc)

NIST-CHiMaD Postdoctoral Fellow

NIST-CHiMaD Postdoctoral Fellow  (2019- Present)

  • Develop and validate all atom molecular dynamics simulations protocols to study polymers/block copolymers' properties such as density, radius of gyration, surface tension, glass transition temperature etc

  • Study effects of block composition in random block copolymers on surface tension and density

  • Collaborate with external researchers (prof. Juan de Pablo and Paul Nealey labs in the University of Chicago) to develop block copolymers materials for lithographic applications

Postdoctoral Fellow (2017 - 2019)

Department of Materials Science and Engineering, Northwestern University, Evanston IL

Supervisor: Prof. Monica Olvera de la Cruz

  • Developed coarse-grained molecular dynamics simulations approaches to study proteins self-assembly

  • Studied effects of surface charge density, solution pH/protein charges, salt and protein concentrations on protein adsorption modes (“standing up” vs “flat on” vs a mixed state) and pattern formations on surfaces

  • Investigated physical properties of linkers (both free linkers and grafted linkers to protein surface cases) for constructing porous yet order protein superlattices

Graduate Research Assistant (2012 - 2017)

Department of Physics, Kansas State University

Supervisor: Prof. Jeremy Schmit

  • Developed models to represent protein states for understanding mechanism of salting in/out and Hofmeister effects

  • Calculated free energies of protein states at various conditions such as salt concentration, salt type, and solution pH

  • Developed and implemented Monte Carlo simulation model to investigate protein crystal growth and associated growth self-poisoning (one of the kinetic traps)
