I am a senior data scientist working on natural hazards and climate risk analytics at Cotality. Views on this personal website represent my own and not that of my employer. I help the financial sector understand natural hazard risk posed to properties and the built environment. I work on algorithms for generating a property portfolio from geospatial and tabular inputs as well as data crunching and AI/ML processing of climate model data for hazard probabilities and severities I work in BigQuery (GoogleSQL), Python, and R to handle O(100M) row (geospatial) tabular data and TB's of high resolution climate model rasters. Accomplishments include spearheading an inter-team data quality and improvement effort, pushing a data audit that saved $100k+ per year in cloud costs, and a data science organization award for boosting collaboration with the University of California San Diego. I have also served as a mentor for the UCSD Data Science undergraduate capstone course.
In prior roles I applied statistical and data science techniques to identify and characterize patterns in the large volumes of remote sensing imagery, climate data, and in-situ observations and to relate these patterns to physical processes. This enables us to make data-based and physically-informed evaluations of landscape vulnerability and resilience. I earned a PhD in the Department of Civil and Environmental Engineering at the University of California Irvine where my research was supported by a NASA Earth Space and Science Fellowship and a UC Laboratory Fees In-Residence Graduate Fellowship involving collaboration with Los Alamos National Laboratory. The incredible advisors who have guided my research journey include Efi Foufoula-Georgiou, Alejandro Tejedor, Joel C. Rowland, and Naresh Devineni.
My PhD research focused on how permafrost influences the morphology and hydrology of arctic deltas (ADs). We are working to understand how the patterns of thermokarst lakes on these landscapes contain information on permafrost process influence on delta formation and the fate of arctic deltas under warming. Another coastal geomorphology question of interest is the quantitative characterization of river delta shorelines. Lastly, I am presently collaborating with researchers at UCI and internationally on other coastal dynamics topics including understanding why some delta channel networks have become stagnant, graph theoretic characterization of delta channel networks, and analyzing the space-time variability of Southern California's metropolitan beaches.

A little bit about me: I am a strong believer in Free and Open Source Software and reproducible research. The above research was conducted almost entirely in R & Python and portions have been published on GitHub. One of my favorite hobbies is reading; some favorite authors, in arbitrary order, include George Orwell, Philip K. Dick, Robert A. Heinlein, Brian Fagan, Ursula K. Le Guin, Carl Sagan, Howard Zinn, Barbara Ehrenreich, David Graeber, Gabriel Garcia Marquez, Hannah Arendt, and many more. I also enjoy hiking, camping, cooking, and (reading) history.
