Hi, I'mHamster.

A
Self-driven, quick starter, passionate researcher with a curious mind who enjoys solving complex and challenging real-world problems.

About

I am a First Year Master Student at University of Michigan - Shanghai Jiao Tong University Joint Institute. I enjoy problem-solving for the fields of time-critical computing and coding, of course! Always strive to bring 100% to the work I do. In my undergraduage study, I have worked on technologies like C/C++, Python, Shell, Cuda, MatLab, MySQL, Java during research and course projects. I have 6 months of professional work experience which helped me strengthen my experience in Python and Shell. I am passionate about developing complex applications that solve real-world problems impacting millions of users.

Research Interests:
  • Real-Time System Scheduling for Heterogeneous Systems
  • Mathematical Timing Analysis for Real-Time Computing
  • Time Critical Computing in Modern Operating Systems
