Howard Chen

I recently received my PhD in CS from Princeton, where I was co-advised by Danqi Chen and Karthik Narasimhan.

My research goal is to build systems that can continually learn.
Specifically, I aim to build lifelong agents that can operate reliably over long interactive horizons and evolve through self-update. I approch it through the lens of memory in both its in-context and parametric forms: designing challenging evaluation to stress test long-horizon agentic capabilities (WebShop), developing algorithms that let models self-organize and manage its long-term memory (MemWalker), examining reliability under context accumulation (Tracking Belief Shift), and understading how model parameters can be updated without drastic forgetting of old knowledge/capabilities (Continual Memorization, RL Mitigates Forgetting). I am also broadly interested in topics like interpretability and safety from the memory perspective.

During my PhD, I have interned at Meta (FAIR) working with Asli Celikyilmaz and Jason Weston. Prior to Princeton, I was an ML researcher at ASAPP working with Tao Lei. I was also a research assistant at Cornell Tech working with Yoav Artzi.

I recieved my M.Eng. in CS from Cornell and B.S. in EE from
National Taiwan University.
