My colleague, Ray Tuminaro, and I from a Sandia Lab News article on our land-ice modeling work.
I am currently a Principal Member of Technical Staff (PMTS) in the Quantitative Modeling & Analysis Department at Sandia National Laboratories in Livermore, CA. Prior to joining this group, from October 2011 to September 2014, I was a Senior Member of Technical Staff (SMTS) in the Computational Mathematics Department at Sandia in Albuquerque, NM. I received my Ph.D. in Computational and Mathematical Enineering (CME) from Stanford University in 2011. My advisor at Stanford was Professor Charbel Farhat and I was a member of the Farhat Research Group (FRG). My Bachelors and Masters degrees are in pure mathematics, awarded by the University of Pennsylvania in 2006. While a Ph.D. student at Stanford, I had the opportunity to work part time and during the summers as a Graduate Technical Intern in Sandia Albuquerque's Aerosciences Department.
In 2019, I was named one of the recipients of the Presidential Early Career Award for Scientists and Engineers (PECASE) for “developing new, impactful mathematical methods and computer algorithms to enable real-time analysis, control, and decision-making on computationally prohibitive problems relevant to nuclear security mission and climate modeling.” Other honors I have received include winning the Robert J. Melosh medal for the best student paper in finite element analysis in 2008, and, in 2007, being awarded two fellowships which funded my graduate studies, the National Defense Science and Engineering Graduate (NDSEG) fellowship and the National Physical Science Consortium (NPSC) fellowship.
In January 2015, I got married and changed my last name from Kalashnikova to Tezaur. As a consequence, I have publications/presentations under both names.
- Numerical solution to PDEs.
- Enriched finite element methods.
- Stability and convergence properties of numerical methods.
- Reduced Order Modeling (ROM).
- Climate modeling.
- Multi-scale coupling methods.
- Performance portability of codes to next-generation architectures.
- Scientific computing/HPC.
- Software engineering.

Here is also a very nice video of my colleague Kara Peterson describing the latter project that accompanies the article in the report.

July 2019: President Donald J. Trump issued a press release announcing that I am one of the recipients of the Presidential Early Career Award for Scientists and Engineers (PECASE) for “developing new, impactful mathematical methods and computer algorithms to enable real-time analysis, control, and decision-making on computationally prohibitive problems relevant to nuclear security mission and climate modeling.” Additional press releases have been issued by the NNSA, Sandia Lab News, SNL's Center 8000, the ABQ journal, the Livermore Independent News, and the Secretary of Energy Rick Perry. Below are a few photos from the White House and DOE ceremonies, both of which took place in Washington D.C. on July 25.
