Yangfan Li

Yangfan joined the Clinical Trial Service Unit and Epidemiological Studies Unit (CTSU) in October 2024 as a DPhil student, under the supervision of Associate Professor Christiana Kartsonaki from CTSU and Professor Ruth Keogh from the London School of Hygiene & Tropical Medicine (LSHTM). His project focuses on developing advanced risk prediction models in case-cohort studies and other complex study designs, with emphasis on adapting machine learning methods to account for the sampling scheme.

Prior to his DPhil, Yangfan completed his MPhil and then served as a health data scientist at the University of Cambridge. His MPhil project, in collaboration with AstraZeneca, focused on developing Bayesian hierarchical and neural network models for drug screening evaluation. During his role as health data scientist, he studied the robustness and transferability of risk prediction models, quantifying the distributional shifts in electronic health records across time and cohorts and their impact on cancer risk prediction models.
