About Me

Hello! This is Jiachen. More about my name… Jiachen is pronounced “chia-ch’en”, and my name is written as Chinese in Chinese. Feel free to call me James!

I’m a Ph.D. student in Computing and Mathematical Sciences at Caltech, where I am fortunate to be advised by Professor Anima Anandkumar. My research lies at the intersection of generative modeling and scientific computing.

Prior to my PhD, I completed my undergraduate studies at Tsinghua University, where I had the privilege of working with Professor Jun Zhu and Professor Hang Su on physics-informed machine learning. I am also grateful for the opportunity to conduct research at Stanford University, where I worked with Professor James Landay and Professor Monica Lam on human-AI interaction.

Research Interests

My long term goal is to develop a unified framework that learns and uses efficient representations of data, domain knowledge, and available observations to model complex systems. I am particularly interested in generative approaches to achieve this objective.

I am interested in the intersection of generative modeling and physical sciences. Scientific problems are often ill-posed, and the strong priors offered by generative models can significantly enhance robustness and efficiency. However, these models typically require vast amounts of data and lack physics guarantee. Therefore, I focus on developing scalable, uncertainty-aware methods for generative models + scientific inverse problems.
