Hanchen Wang

Hey! I am a third/final-year PhD in Machine Learning at Cambridge, working with Prof. Joan Lasenby from Trinity. During PhD, I also spend some time at Isaac Newton Institute, Cambridge Math, Google Research, Amazon Alexa, BioMap, ZhenFund, Entos, and Caltech (with Prof. Anima) [where I live].

I earned a Physics BS from Nanjing University (2018), visited Stanford & Cal, worked in Finance (S&T, Quant), co-founded a Startup on Digital Health. I was admitted to University at age 15, and later served as the Valedictorian.

Research Interest

I work on 3D and Graph structured data, emphasizing Representation Learning & Health topics.
I also spent time on Federated Learning, MLSys, Quantum Computing & Signal Processing.
I now mainly work on AI/ML + Functional Genomics (Editing) & Synthetic Biology.
