Welcome to Karianne's Website!
I am an Assistant Professor of Data Science and Earth, Environmental & Planetary Sciences and Assistant Professor of Computer Science at Brown University.
My research interest is in scientific machine learning (SciML). My past work has focused on machine learning for pattern recognition and discovery in large, noisy sensor data sets, with applications in earthquake seismology and biodefense. My research group's recent and upcoming work focuses on (1) machine learning-based surrogate models (emulators) and data enhancement (downscaling), with applications in Earth and Climate science, (2) explainable AI (XAI) for scientific data, and (3) scientific foundation models.
I did my postdoctoral training at Harvard University as a Data Science Initiative Postdoctoral Fellow in Computer Science. I earned my Ph.D (and M.S.) in Computational and Mathematical Engineering at Stanford University, and my B.Sc. in Applied Mathematics from Brown University. I have also worked as a data scientist at MIT-Lincoln Laboratory.
I am also passionate about data science education and workforce development in data science, including supporting women interested in exploring data science careers. I have taught a number of courses and workshops that aim to make data science accessible to students and professionals from a range of disciplinary backgrounds.
Thanks for visiting!
