Huan Ke is a PhD student in the Department of Computer Science at the University of Chicago. Her supervisor is Professor Haryadi S. Gunawi. Currently, she is doing her internship in Los Alamos National Laboratory, where she primarily works with Bradley Settlemyer. Her research interests lie in the system performance, reliability and scalability. Particularly, she works on modelling system behaviors, detecting concurrency bugs, optimizing tail-latency problems, and checking scalability issues. Now her research agenda explores how to develop new data layouts to tolerate massive failures in the large-scale storage systems.
