$ whoami

I am Tianyin, a Night's Watch and a day dreamer who tries to do relevant systems research. I am enjoying my PhD at sysnet and opera, UC San Diego, working with YY (my rock star advisor). The biggest thing I learned is being serious and sincere—Winter is coming! Don't fight a fake war or someone else's war. Fight for what matters to the living and the dead!

I work with NetApp where I research system products and observe system users. I had a very short experience in Whova and learned dedication and responsibility. Before came to UCSD, I worked in Germany for 1.5 years at Goettingen.

$ head research_interests

The goal of my research is to make computer systems reliable and secure. My mission is to help today's systems defend against all kinds of errors and defects, such as software bugs, configuration errors, and design flaws. I am proud that some of my research helps improve real software systems. See the list of issues I helped.

As a systems guy, I am interested in various inter-disciplinary black magic, e.g., program analysis, machine learning, and NLP. My view of systems research is to build the right swords to kill the dragon (not windmills!).
