Rich Pauloo, PhD


About me

I'm a hydrogeologist developing scientific methods to monitor, model, and manage regional-scale aquifers, with applications in sustainable groundwater management, agricultural water use, and real-time natural resource monitoring. I've built simulations of groundwater flow and contaminant transport, open source frameworks for real-time groundwater monitoring, and models that predict if a well may run dry during drought or unsustainable management.

Science communication is core to my interests. 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 for weeks on end in far corners of the Earth, speaking to large crowds, communicating science to diverse audiences, and improvising.

Outside of work, I like to learn new things, cook, playing guitar, explore the alpine environment with a rope and harness, take bike tours, and catch waves in the cold California ocean.
