Ana Nora (Sovarel) Evans

I am a PhD candidate at the University of Virginia, advised by Professor Mary Lou Soffa.
I am interested in applying formal methods to improve the quality and safety of software.

I have a MS in Mathematics (2014) and Master of Computer Science (2006), both from UVa.

I am hosting the Charlottesville Math Circle with David Evans. If you have a five to seven year old girl interested in Math and puzzles please join us.
