Research

My peer-reviewed publication list is available at Google Scholar Profile.

At QuesTek, I lead and contribute to various government/commercial/internal projects. Most of these projects are research-oriented, focusing on different topics in the field of integrated computational materials engineering (ICME) and materials genome. To name a few:

  • CALPHAD in the Cloud
  • Materials Genome and Integrated Computational Materials Engineering Toolkit
  • Mechanistically Enhanced Machine Learning for Materials Design and Process Optimization

During my PhD and postdoc, my research has focused on atomic-level computational studies of materials:

  • Energetics and phase stability of chemically (partially) disordered alloys and oxides
  • Phonon vibrations in crystalline materials
  • Density functional theory (DFT) simulation of alloys with magnetism
  • Defect formation in solid solution alloys
  • Transition state of point defects in crystalline materials using nudged elastic band method
  • Marchov Chain Monte Carlo simulation combined with DFT
