Sidharth Kumar

Assistant Professor at UAB CS

My research lies at the intersection of HPC and Data Analytics. More broadly, I work on problems in parallel computing, big data processing, parallel I/O, scalable algorithms, large data file formats and performance modeling.

I am looking for students!
