Rich Pauloo, PhD

Data Scientist

Hi ๐Ÿ‘‹, my name is Rich.

I'm a data scientist at LWA and spend most of my time in R automating ETL pipelines for sensor networks ๐Ÿ“ก, building Shiny Apps and dashboards ๐Ÿ–ฅ, designing approaches with spatial statistics and hydrologic models, and generally wrangling lots and lots of data.

I have a PhD in Hydrology and my dissertation is titled ‘Emerging consequences of regional-scale aquifer depletion: data-driven and numerical models of well failure, basin salinization, and contaminant transport’ (my exit seminar can be viewed here). Early in my PhD, I found that I really enjoyed data science and programming, and I used these years to sharpen those skills. My published research includes NLP and network analysis, spatial statistics, and physical modeling of 3D, subsurface contaminant transport.

I'm an #rstats nerd and automation/reproducibility fanatic. My favorite tools include tidyverse (dplyr, ggplot2, purrr), shiny, flexdashboard, DT, RMarkdown (for dashbaords/reporting), sf, sp, raster, leaflet (for spatial data), and DBI for databases. A few projects I'm proud of include an R package to query water quality data ๐Ÿ“ฆ, R data science curriculum ๐Ÿ“š, a dashboard that makes millions of water quality observations understandable ๐Ÿ“ˆ, and a model that predicts the risk of wells going dry ๐Ÿ’ง funded by Microsoft's AI for Earth Grant.

Before my PhD, I taught environmental science to middle and high school students in Yosemite and the Marin Headlands for the educational nonprofit NatureBridge. I spent summers leading expeditions in the wilderness, and in Thailand for National Geographic Student Expeditions.

In my free time, I enjoy anything that puts me in a flow state: alpine climbing ๐Ÿง—๐Ÿผ, running ๐Ÿƒโ€โ™‚๏ธ, surfing ๐Ÿ„โ€โ™‚๏ธ, tinkering on bikes ๐Ÿšดโ€โ™‚๏ธ, reading ๐Ÿ“š, playing guitar ๐ŸŽธ, and cooking ๐Ÿง‘โ€๐Ÿณ.
