Hanchen Wang

Hey, I am a 2nd Year PhD (2019-) in Info Engineering (i.e. Computer Science) at Cambridge, where I work with Joan Lasenby and Adrian Weller, mainly on Efficient Geometric Deep Learning (i.e., 3D & Graph Representations).
Previously I worked with Hao Dong, Ali Javey and Xinran Wang on various topics incl. Electronic/Photovoltaic Devices and Computational Biology.
My PhD is supported via donations from Kathy Xu and Cambridge Trust.

I've obtained bachelor degrees in Physics and Info Engineering from Nanjing University (-2018, admitted at 15). During college, I've spent time in places incl. Berkeley EECS, Stanford EE, Meiji Japanese, MingShi Investment and China International Capital Corporation.
