Yichun He
I'm a Ph.D. candidate at Harvard University School of Enginnering and Applied Sciences and the Broad Institute of MIT and Harvard.
I'm fortunate to be advised by Prof. Jia Liu and Prof. Xiao Wang.
I also interned in Prof. Aviv Regev's lab at Genentech with Hanchen Wang and Paula Coelho during the summer of 2024.
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 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 Biological Processes and Behaviors
- (4) Integrating Diverse Biological Data to Understand Cell States and Dynamics
- (5) Enabling Autonomous Experimentation, Analysis, and Scientific Discovery
