RESEARCH EXPERIENCE (Highlights)

University of Washington, Seattle, WA (Dec. 2014 – Dec. 2016), Postdoctoral Research Fellow

Performed atomic-level molecular dynamics simulations of proteins (up to 0.5 million atoms) at air/water interfaces and in solution using high performance computing Linux cluster.

Implemented mathematical models in Python to quantify molecular orientations, relaxation, and protein self-assembly from a very long (~0.5 billion time steps) atomic simulation trajectories.

Validated the mathematical model by collaborating with an experimental research group and published the results in a peer-reviewed international journal.

The University of Akron, Akron, OH (Aug. 2010 – Dec. 2014), Researcher

Performed atomic-level molecular dynamic simulations (0.3 million atoms) of a conjugated polymer using high-performance computing Linux cluster.

Developed analysis codes in Perl that convert atomic trajectories to quantified structure, dynamic and interfacial properties; and validated work with experimental measurements and published the results in 3 peer-reviewed international journals.

Implemented an algorithm in Perl to map simulation parameters from all-atom model to coarse-grained model for a conjugated polymer.

Simulated a conjugated polymer using the coarse-grained model that reduced the system’s size by 6x and accelerated it by 100x while predicting structural properties with 95% accuracy.

Eindhoven University of Technology, Eindhoven, The Netherlands (Oct. 2005 – Nov. 2008), Researcher

Developed Fortran code and simulated charge-carrier mobility in disordered host-guest semiconductors.

Fitted the numerical results to physics-based empirical model that was used to simulate devices under different operating conditions; results were published in 2 peer-reviewed international journals.

Developed a Monte Carlo algorithm in C++ that calculated charge-carrier conductivity in molecular-doped semiconductors and validated the numerical results by collaborating with experimental researchers.
