I am currently an assistant professor in the Department of Biostatistics and Health Data Science at Indiana University School of Medicine. Previously, I was a postdoctoral fellow in the Department of Biostatistics and Bioinformatics at Emory University, under the supervision of Dr. Amita Manatunga, Dr. Limin Peng and Dr. Ying Guo. My research interests include:

  • high-dimensional tensor data analysis with application to multimodal neuroimaging data,
  • joint analysis of intermittently observed longitudinal data and complex time-to-event data, including right-censored and interval-censored survival data, and panel count data,
  • statistical analysis for mental health studies, criminology and clinical trials.

I obtained my Ph.D. in statistics from the University of Missouri, advised by Dr. Jianguo (Tony) Sun. I earned my M.Phil. in statistics from The Hong Kong Polytechnic University, supervised by Dr. Xingqiu Zhao and Dr. Zhisheng Ye, and a Bachelor of Science from the same institution.

I am looking for potential doctoral students with strong quantitative and computing skills. If you are interested, please send your CV and other relevant documents to dayusun [at] iu.edu.
