Research Interest
Additive Manufacturing
Implemented 2D thermal finite element model (2d-heat-ded on GitLab) of directed energy deposition additive manufacturing process (animations) in Python using FEniCS framework. The model matched pyrometer measurement of melt pool length and was presented at FEniCS'19 conference and published in the Journal of Manufacturing Processes.

Particle Motion in Fluids
Parallelized 3D LBM code for partially saturated computational cells, coupled with Discrete Element method (summary), featured in MSU headline news.

Alloy Solidification
Parallelized 2D and 3D alloy solidification code (JCP article with source code, presentation), achieved a landmark featured in the 2012/09/19 HPC research spotlight.
XSEDE - single largest Mississippi allocation in 2013
Electrokinetic Phenomena
Revealed Charge density effects on the nanoflow (DOI), presentation, animated pressure equilibarion.

Density Functional Theory, Molecular Dynamics
Developed a MEAM potential for Al, Si, Mg, Cu, and Fe alloys (included in a NIST database), PRB journal article - results reproducible with Python ASE scripts published in GitHub repository, presentation

Speech Recognition using Hidden Markov Models
Worked on ISIP ASR system, sample C++ code and documentation.
