I am a Ph.D. student at the Department of Computer Science at Dartmouth College. I am a member of the DartNets (Dartmouth Networking and Ubiquitous Systems) Lab, under the supervision of Prof. Andrew T. Campbell.
Before joining Dartmouth, I had 3 years industrial experience at KLab and Works Applications as a software engineer. I obtained my Master's degree from Waseda University under the supervision of Prof. Satoshi Goto. I obtained my bachelor's degree in Software Engineering from Nanjing University in China.

Research Interests

  • Human behavioral modeling using data from mobile systems and social networks
  • Ubiquitous computing, mobile sensing applied machine learning, mobile health and data mining
  • Design and implementation of mobile sensing systems, including apps on iOS and Android platforms, back-end, and human-generated data management

What's New

  • Jul. 2018: Second paper newly accepted by UbiComp'18!
  • Feb. 2018: The recruiting and screening website for Mobile RDoC is online!
  • Jan. 2018: Our paper accepted by UbiComp'18!
  • Oct. 2017: Project kick-off at UW, Seattle (Mobile RDoC). The project uses smartphone technology to understand auditory verbal hallucinations.
  • Sep. 2017: Launch a new NIH study at Dartmouth. The study will follow a large cohort of participants over their four years of college to assess how changes in self- affect are predicted by relevant brain networks as well as how those networks change over time.
  • Sep. 2017: Great time at Ubicomp'17, Maui. Rui presented our work in predicting symptom trajectories of schizophrenia using mobile sensing.
  • Jun. 2016: Start to work in the EUREKA NIH project which tries to achieve illness monitoring in schizophrenia from the behavioral data collected by smartphones.
