Brooks Groves

GIS Analyst & Data Scientist Β· Zillow Β· Lakewood, WA

I was born in Sonora, California and grew up in Groveland β€” a small mountain town at the western edge of Yosemite, elevation 2,800 feet, population not many. My parents were Forest Rangers, which meant I grew up around the Evergreen Lodge and Mather, CA, with the whole of the Sierra Nevada as a backyard. I learned to swim in the Tuolumne River β€” Rainbow Pools specifically, a classic California swim hole carved into the granite just downstream, the kind of place that only makes sense to people who grew up near one. I hiked Yosemite before I knew what hiking was. Every summer when Tioga Pass opened, the world got bigger β€” over the pass and down to Mono Lake, that strange alkaline otherworld on the east side.

The Sierra Nevada shaped how I see the world: as terrain first, elevation second, everything else a distant third. Then came a detour to the Texas Hill Country β€” Brenham, Blinn College, a different kind of landscape entirely β€” trying to figure it all out deep in the heart of Texas before heading back west to Nevada and eventually north to Seattle.

After studying molecular biology and desert ecology at the University of Nevada, Reno β€” lichenology, bryology, C4 photosynthesis, the cryptobiotic world living on rock faces across the Great Basin β€” I spent time at the University of Cape Town working with Doug Rawlings on bioleaching and acidophilic microorganisms. Then graduate work in astrobiology at the University of Washington, studying sea ice bacteria and extremophile microbiology. That ended abruptly when the WTO Riots hit Seattle in November 1999 and I had to defer and go to work full time. Then I ended up in the Westin, where I spent 21 years as bell captain at the Westin β€” one of the largest hotels in the Pacific Northwest. That job taught me more about human nature than any classroom. I watched the city change from the inside of a revolving door: the dot-com boom, 9/11, the slow recovery, the tech explosion. I met several sitting presidents, dozens of world leaders, Hall of Fame athletes, and Snoop Dogg β€” more than a few times. I wrote most of it down.

In 2017 I went back to school at the University of Washington and completed a certificate in Geographic Information Science and Cartography. I've been at Zillow since 2019 β€” first as a GIS Technician, now as a GIS Analyst and data scientist β€” building spatial pipelines, analyzing market data, and finding patterns in the geography of real estate.

Outside of work I build open-source dashboards and data tools: streamflow monitors, snowpack trackers, wildfire response analyses, Mariners analytics. I run, swim, and ride. I geocache. I watch too much pro cycling. I read constantly and write when I can.

This site is the place where all of it lives β€” the technical work, the writing, the data, the mountains.

1970
Born in Sonora, CA Β· Grew up in Groveland, CA
Tuolumne County. Parents were Forest Rangers β€” grew up around the Evergreen Lodge and Mather, CA. Learned to swim in the Tuolumne River at Rainbow Pools, a granite swim hole on the South Fork. Hiked Yosemite before knowing what hiking was. Tioga Pass opening every summer meant the east side β€” Mono Lake, the high desert, a different California entirely. The Sierra Nevada as a classroom that never closed.
~1980
Donald L. Rheem Elementary β€” Moraga, CA
4th grade. Moraga, Contra Costa County β€” a different California entirely from the Sierra Nevada.
~1981–82
Janesville Elementary β€” Janesville, CA
5th and 6th grade. Dad transferred to the Plumas National Forest. Go Wildcats β€” again. Played Little League baseball at 1st base for both the Janesville Pirates and the Janesville Dodgers. In an enrichment program focused on national parks, wrote a letter to President Ronald Reagan about establishing a new national park in the area β€” and he wrote back. Still need to find that letter.
~1988
Sonora Union High School β€” Sonora, CA
Go Wildcats. Tuolumne County. The mountains were right there the whole time.
~1988–90
Blinn College β€” Brenham, TX
Deep in the heart of Texas Hill Country β€” trying to figure it all out far from the Sierra Nevada. Rolling limestone hills, live oaks, a completely different geology and a completely different pace. Brenham sits between Austin and Houston, bluebonnet country. Eventually figured out enough to point the compass back west.
1990–96
University of Nevada, Reno β€” B.S. + Graduate Studies
B.S. Molecular Biology, then graduate studies. Worked with Dr. Lee Weber on heat shock proteins in Lahontan cutthroat trout and the Tui chub around Pyramid Lake. Coursework with Dr. Vineyard in Desert and Montane Ecosystems β€” the kind of class that changes how you read a landscape. Working with Dr. Don Prusso deepened an interest in lichenology and bryology in desert ecosystems β€” the cryptobiotic world living on rock faces and soil crusts. Developed a deep fascination with the C4 photosynthetic pathway found in many desert plants including cacti β€” the biochemical workaround that lets plants fix carbon efficiently in extreme heat. The Basin and Range as a living laboratory. Still carrying most of it.
1996
University of Cape Town β€” Cape Town, South Africa
Between UNR graduate work and arriving in Seattle β€” spent time with Doug Rawlings in the early days of what would become UCT's Centre for Bioprocess Engineering Research (CeBER) β€” now one of the top mineral bioprocessing programs in the world. Work focused on iron- and sulfur-oxidizing acidophiles for bioleaching and metal recovery. The intersection of microbiology and mining engineering, before either field fully knew what to do with the other.
1997–99
University of Washington β€” Graduate Studies, Astrobiology
Arrived in Seattle to study astrobiology β€” specifically sea ice bacteria and extremophile microbiology, the organisms that survive at the edges of what life tolerates. The research had direct connections to the search for life in analogous environments beyond Earth. Studied through late 1999 until the WTO Riots upended the city in November. Had to defer graduate work and go full time at the Westin Seattle. Stayed 21 years.
1997
Joined the Westin Seattle
Started as a bellman on the graveyard shift. Eventually became bell captain. Watched Seattle transform from the inside of a revolving door: the dot-com boom, 9/11, the tech explosion, Amazon moving in. Met several sitting presidents, dozens of world leaders, and Snoop Dogg β€” more than a few times. Wrote most of it down.
