Yichun He

I'm a final-year Ph.D in the School of Enginnering and Applied Sciences at Harvard University and Broad Institute of MIT and Harvard , advised by Prof. Jia Liu and Prof. Xiao Wang. I also worked with Prof. Aviv Regev and Prof. Jie Ding. I received bachelor's degree in Electrical Engineering at the University of Science and Technology of China with the highest honor Guomoruo Scholarship.

My research explores the complex biological systems across multi-scales, from molecular features and cell identities to tissue structures, functions and behaviors. I develop artificial intelligence (AI), machine learning (ML), and multi-agent systems solutions with applications in spatial multi-omics and brain machine interfaces to advance the understanding of biology and health.

Research

I am passionate about accelerating discovery in biology and health through advanced AI/ML approaches. My work spans multiple directions, including:

(1) Mapping Spatially Resolved Cell Types and Molecular Profiles at Scale
(2) Linking Cellular Characteristics to Spatial Contexts Across Technologies and Conditions
(3) Uncovering Long-Term Cell Functions and Behaviors
(4) Integrating Diverse Biological Data to Understand Cell States and Dynamics
(5) Enabling Autonomous Experimentation, Analysis, and Scientific Discovery
