About Me

  • I’m Yun-Yun (Alice) Tsai (蔡昀芸), an incoming Ph.D. student in the Department of Computer Science at Columbia University, advised by Professor Junfeng Yang.
  • My research interests lie in Security and Artificial Intelligence, which I am particularly interested in improving trustworthy, security, and robustness over machine learning (ML) algorithms and computer systems.
  • I received M.S. and B.S. in computer science, both from National Tsing Hua University (NTHU), Taiwan. Previously, I was advised by Professor Tsung-Yi Ho and Dr. Pin-Yu Chen from IBM Research Trusted AI group.

Extra Activites

    Besides my academic research passion, I am also a versatile musician and have participated in many extracurricular music activities. With over 20 years of performing and training in playing the piano and viola, I was selected as the 1st chair of viola in Tsing Hua Symphony Orchestra for 4 years in college and performed more than 20 concerts on public stages such as National Concert Hall. I also won the NTHU concerto competition in 2017 and was honored to be the piano concerto soloist at the annual concert of NTHU Orchestra.
