BIOGRAPHY
Dr. Yicheng Zeng is currently a research scientist in Shenzhen Research Institute of Big Data. Before that, he was a postdoctoral fellow in Statistics at the Department of Statistical Sciences, University of Toronto, from 2019 to 2022, hosted by Prof. Qiang Sun and Prof. Yuying Xie. He earned his Ph.D. in Statistics from Hong Kong Baptist University in 2019, under the supervision of Prof. Lixing Zhu and Prof. Heng Peng. Prior to that, he received his B.S. from Tianjin University in 2014, and his M.S. from Zhejiang University in 2016, where he was supervised by Prof. Zhonggen Su. His research interests include high-dimensional statistics, statistical learning, statistical applications of random matrix theory, dimensionality reduction, and order determination, etc. He has published several peer-reviewed papers on statistical journals and machine learning conferences including Statistica Sinica, JMVA, CSDA, ICML and UAI. He also serves as an anonymous reviewer for statistics journals and conferences, including Biometrics, Communications in Statistics - Theory and Methods, AISTATS (2022&2023). Dr. Zeng is currently the PI of a Shenzhen Excellent Science and Technology Innovation Talents Cultivation Project (PhD Start-Up) from Shenzhen government.
