I teach computer science instructor at the University of Colorado. I'm interested in numerical computation, languages and compilers, and computer science pedagogy.
I’m currently teaching for the post-baccalaurate program. I teach:
DSLs and Search for Linear Algebra Performance
Advisor: Elizabeth Jessup
I designed search algorithms and ran performance testing for two domain-specific languages, in the domains of matrix and tensor algebra. These languages allow the user to specify high-level mathematical kernels, and the search algorithms automatically test many code transformations and optimizations, searching for best performance on CPUs and GPUs.
Genetic Algorithms with Chaotic Population Dynamics
Advisor: Elizabeth Bradley
I created a genetic algorithm with a population that could grow and shrink periodically or chaotically. I then evaluated the algorithm's performance under fixed, periodic, and chaotic populations in solving optimization problems.
