Pau Batlle

I am a mathematician currently working in industry. I was previously a postdoctoral scholar in the Computing and Mathematical Sciences Department at Caltech, working with Professor Houman Owhadi. I obtained my PhD in June 2025 in the same research group. During my PhD, I was a research affiliate at NASA Jet Propulsion Laboratory.

My research is at the intersection of Statistics and Applied Mathematics, including:

• Frequentist confidence intervals in ill-posed inverse problems using optimization

• Game-theoretical Uncertainty Quantification

• Theory and Applications of Gaussian Processes

See my research page for an in-depth explanation. I have applied my work to different domain applications, including remote sensing, biology, earthquake prediction, epidemic modeling, and telecommunications engineering.

Before joining Caltech, I graduated from Universitat Politècnica de Catalunya with a double undergraduate degree in Mathematics and Engineering Physics as part of the CFIS program, and I was a research visitor at the Center for Data Science at NYU.
