I am a first-year PhD student at UC San Diego, advised by Prof. Rose Yu. I was a research intern at Palo Alto Research Center (PARC) in summer 22 (and continue being affiliated as a visiting researcher) working with Dr. Kalai Ramea at the intersection of climate modeling and machine learning (ML). Before, I had the pleasure to be researching at Mila - Quebec AI Institute, with Prof. David Rolnick on climate change+ML.

I got started in ML research through a project on weakly supervised learning with Ben Boecking and Prof. Artur Dubrawski at Carnegie Mellon University's Auton Lab. I also led a diverse team of fellow undergraduates in our research project on improving El Niño forecasts with graph neural networks, in terms of both performance and interpretability. We were supported by a Microsoft AI for Earth grant ( see our spotlighted profile).

I am German-Peruvian, and was privileged to be able to grow up in both countries and that volunteering/work enabled me to have a wonderful time living in Colombia, India, and Canada for extended periods of time. I enjoy immersing myself into nature and new cultures, travelling, and exotic fruits. As I now live in sunny San Diego, surfing will probably be on that list soon too!

My goal is to develop and use machine learning methods for positive real-world impact in areas like climate science, climate change, and sustainability. On the machine learning side, I am particularly interested in self-supervised learning, graph structure learning, spatiotemporal forecasting, and conditional generative modeling (including diffusion models, of course :).
