Rich Pauloo, PhD

Hydrologist and data scientist

About me

Groundwater resources support global food supply and civilization, yet are in decline worldwide. I use my background in hydrogeology and data science to develop scalable and scientific methods to monitor, model, and manage regional-scale aquifers. I've built open source frameworks for real-time groundwater monitoring, models that predict if a well may run dry during drought or unsustainable management, and 3D physical simulations of groundwater flow and contaminant transport.

I'm passionate about data literacy and STEM education, the outdoors, and expedition behavior. Before pursuing a PhD, I taught environmental science to middle and high school students in Yosemite and the Marin Headlands for the educational nonprofit NatureBridge, and spent summers leading expeditions in the wilderness, and in Thailand for National Geographic Student Expeditions. I love the challenge of guiding tight knit groups from different cultures across difficult terrain, speaking to large crowds, communicating to diverse audiences, and improvising.

In my free time, I enjoy alpine climbing, running, surfing, tinkering on bikes, reading, playing guitar, and cooking extravagant dinners.
