Key Research Directions
I believe artificial intelligence should serve humanity and the social good, and that comes from transparency, alignment, and broad collaboration. We pursue AI that is accessible, reliable, responsible, and mechanistically explainable, empowering people rather than replacing them.
Driven by a commitment to AI for humanity, I am personally deeply interested in boosting collaborative intelligence between carbon-based and silicon-based minds to generate new hypotheses and discoveries across the life sciences, transforming human health and well-being.
🎓 We are offering PhD opportunities via A*STAR AGS Scholarship and co-supervision, and actively looking for Research Interns (both full-time and part-time are welcome) and CSC visiting students. If interested, please email me your CV!
