Welcome

CV: See here. It is being updated regularly.

Research Interest: Distribution-free Uncertainty Quantification, Spatial-temporal Data Modeling, Optimization, Anomaly Detection, Change Detection.

Introduction: I am a 2nd-year Operations Research (OR) Ph.D. student in Georgia Tech ISyE, advised by Professor Yao Xie. I am particularly interested in modeling data with complex spatio-temporal dependency through statistical and optimization techniques and subsequently, provide uncertainty quantification for the estimates with provable guarantees. Please see my Google Scholar page for a list of works. Feel free to contact me at cxu310@gatech.edu if you share similar research interests and/or find my work interesting and inspiring.

Before my PhD, I received my joint BS/MS degrees during 2016-2020 from the University of Chicago. My MS Thesis advisor is Professor Rina Foygel Barber and my MS degree is in Statistics. My BS degrees are Computational and Applied Mathematics (CAM) and Economics (specialized in data science).

Hobby: weightlifting, basketball, reading.

Updates:

  • Septembter 2021: Passed the Ph.D. Comprehensive Exam in Operations Research.
  • August 2021: To work as a part-time intern for Healthcare Xplorers @ Roche Diagnostics on “Develop machine learning-based methods for early anomaly detection in diagnostics instrument and assay data”. The position starts in early 2022.
  • July 2021: To work as a full-time intern in Fall 2021 for the Energy Systems @ Argonne National Laboratory and I am supervised by Dr. Feng Qiu.
