Yeonjoo Park is an Assistant Professor in the Department of Statistics and Data Science at The University of Texas at San Antonio. Prior to UT San Antonio, she was a visiting assistant professor in the Department of Statistics at the University of Illinois at Urbana-Champaign.

Dr. Park's research centers on functional data analysis, particularly on developing statistical methodology for prediction and inference for data with complex dependence structures, including spatial correlation and outliers. She is also interested in extending these methods to spatial data and higher-dimensional settings, and in integrating machine learning techniques with functional data analysis. In addition to methodological research, she has collaborative research experience in biomedical engineering, marketing, and communication.
