I am a staff scientist in the Energy Systems Division at Argonne National Laboratory. Prior to this position, I was a post-doctoral appointee from September 2011 – January 2014 and a pre-doctoral appointee from September 2009 – August 2011 in the Mathematics and Computer Science Division. I received a Ph.D. degree from Illinois Institute of Technology in 2011. Since 2009, I’ve been involved in the development of the high performance library PETSc.

Current projects

Research Interests
My area of research is numerical methods for electrical power system analysis, specifically involving high performance computing and dynamics analysis.

Transient stabilty analysis

  • Adaptive time-stepping and multirate algorithms.
  • Iterative linear solvers and preconditioners.
  • Scalable (parallel) algorithms for large-scale transient stability simulation.
  • Trajectory sensitivity.

Multiscale modeling and simulation

  • Coupled transient stability and electromagnetic transients simulation.
  • Combined transmission-distribution system modeling and simulation.


  • Transient stability constrained optimal power flow.
  • Model predictive control.
