PhD, in Machine Learning, Oct 2019-22 Thesis: Learning from Structured Data with Weak Supervision During my 3-year PhD (supported by 2 fellowships), I shifted to AI and didn't publish ANY paper till the end of the 2nd year. I develop methods (many are pre-training) that can learn structures from data with weak supervisions. I've been working on polls, point clouds, CT/CXR scans, histological and pathological images, molecular and relational graphs. I also explored quantum computing, and interned in tech then biotech (Google -> Amazon -> BioMap -> Iambic). Back in 2019, I co-founded a startup (as the CTO) with friends from Stanford and Cal, building language models on EHRs, partnering with 37 hospitals. Though the startup is short-lived, it deepened my ego to advance sciences, therapeutics and healthcare with AI.

Undergraduate, in Physics, Sep 2014-18 In addition to studying Physics, I researched next-gen electronic devices such as transistors and solar cells, an intersection of Solid-State Physics, Material Sciences and Electrical Engineering. I worked in Xinran Wang's and Ali Javey's groups. I also had some fun in finance, starting with bonds, then moving to equity and crypto trading. Yet these experiences sharpened my ego to make real-world impacts, like using AI to push science forward and improve lives.
