Title: Machine Learning for Science: A Journey from Astrophysics to Climate
Abstract: The two realms of my research are Astrophysics and Climate Science, thanks to a PIVOT fellowship that supports a transdisciplinary arc. I am generally interested in understanding how we can learn from multi-scale simulations using data science tools, and more broadly, in reflecting on how scientists can foster a more responsible AI revolution in society. Some research questions I am considering are: how we can build confidence in machine learning models trained on simulations when they are applied to data; how we can formulate and test hypotheses for model discovery using symbolic regression and causal structure learning; how we can learn effective representations that retain physical meaning and interpretability; and what is the process for building and validating custom metrics to evaluate machine learning models with complex outputs. I will describe some of my work that touches upon these themes, from past and current work in galaxy formation and evolution to early-stage work about global climate models.
