About Me

RK I am a Ph.D. student in computational chemistry and machine learning at Department of Chemistry, University of Zurich, Switzerland. My current research relies on atomistic simulation with ab initio molecular dynamics (based on quantum chemistry) and enhanced sampling techniques to calculate free energies of condensed phased systems. I am now interested in applying machine learning and graph theory to design new molecules and investigate chemical reactions. My interest also extends to the development and improvement of open-source software using cloud-based and full stack technology. I am currently a member of LightChEC and NCCR Catalysis advised by Prof. Sandra Luber.

Before Zurich, I was a scientist at the New Equilibrium Biosciences (from 2019 to 2020) working on computational chemistry and machine learning for drug discovery. I helped the team design and set up AWS infrastructures for performing high-performance molecular dynamics simulations and training neural network models for developing specific-purpose molecular force fields for studying intrinsically disordered proteins (IDP) structures.

In 2016 and 2019, I received Bachelor's and Master's degrees respectively from Thammasat University, Thailand, where I focused on several research topics in computer modeling ranging from density functional theory to multiscale (coarse-grained model) simulation under the supervision of Prof. Yuthana Tantirungrotechai. During my education at that time, I received the NCTU Taiwan Elite International Internship Scholarship and worked at NCTU in the research group of Prof. Jen-Shiang K. Yu in 2015 and 2018, respectively. In 2016, I was also a visiting student at ICTP, Trieste, Italy. In addition, I won the royal winner award of Thailand Computational Chemistry Challenge (TCCC) 2016. For the competition, I used the dissipative particle dynamics technique to investigate the mechanical properties of crosslinking-polyisoprene (natural rubber) reinforced by single-walled carbon nanotubes.
