I joined the Computer Science & Engineering Department
at the University of California Riverside as an Assistant Professor
in 2015, where I am a member of the RIPLE research group.
I was fortunate to work under the supervision of
Xipeng Shen and collaborate with excellent researchers from Pacific Northwest National
Lab, Huawei, Intel and Mozilla.
Program optimization, parallelization, and reliability analysis
on multicore and heterogeneous computing platforms, especially for
automata-based applications (e.g., searching, parsing, querying, and decoding)
and applications with irregular or nested data structures (e.g., tree/graph
Smartphone and mobile app optimization (esp. on Android).
