My first-author papers (Nature, NeurIPS etc.) are highlighted by 1000+ tweets, 50+ press including:
A special collection of Nature, DeepMind, The Economist, Harvard Medical School, Chemical & Engineering News, Tech Crunch, Yahoo! News, a few Wikipedia pages, Tech Xplore, University of Cambridge, healthcare-in-europe.

Besides AI/ML, I'm trained and have published in Physics (my foundation and childhood's favorite, High School Olympiad), Biology (wild learner, also High School Olympiad), Chemistry, Materials / Electronics, Medical Sciences, and Clinical Trials :)

Postdoc, in Novel Therapeutics & Data-Centric AI for Science, Aug 2023-26


Along my postdoc fellowship, I'm excited about the potentials of single cell genomics and AI in developing novel therapeutics. I'm exploring the use of frontier AI (e.g., Foundation Model, Generative AI, ML System, LLM Agent), along with bio frontiers including live cell imaging, organoids, lab-in-the-loop paradigms, AAV & LNP deliveries. Besides, using graph machine learning, I'm developing data centric methods that could benefit many sciences (Biology, Math, Materials etc). Stay tuned!!

Doctoral Thesis: Learning from Structured Data with Weak Supervision

During my three-year PhD (with full fellowship), I shifted to AI, published my 1st paper till the end of my 2nd year (ICCV '21). I have been working on data including votes from polls, point clouds, CT/CXR scans, histological and pathological images, molecular and relational graphs, as well as scRNA-seq. I develop methods (many are pre-training) that can learn structures from these data with weak supervisions. Aside from this, I spent some time on quantum computation also did four interns in tech and biotech industries (Google -> Amazon -> BioMap -> Iambic). Back in 2019, I co-founded a startup (as the CTO) with friends from Stanford and Cal, aimed at transforming electronic health records via language models, with partnerships among 37 hospitals. Though things didn't work out then, my commitment to harnessing AI's power in healthcare remains steadfast.
Last batch of works are near completion: a new cell atlas, a llm for math, a robotics lab. Stay tuned!!!

Undergraduate, in Physics, Sep 2014-18


In addition to studying Theoretical Physics, I researched next-gen electronic devices such as transistors and solar cells, a field at the nexus of Solid-State Physics, Material Sciences and Electrical Engineering. I primarily worked in Xinran Wang's and Ali Javey's groups. I also accumulated experience in the finance sector, initially focusing on bonds then transitioning to roles in quantitative trading of equity and crypto. These diverse experiences ultimately cemented my commitment in advancing Science and Engineering with the aim of improving human life. Finance is boring, technology is fun and the future :)
