CALEB KOOSTRA | ENVIRONMENTAL FIELD TECHNICIAN

Caleb Koostra is an undergraduate senior working for the Center. He is also currently researching paleoclimate reconstruction through cave deposits and advanced analytical techniques. Caleb is our resident ‘bad boy.’ Did you know that his hands are registered as lethal weapons? Nonetheless, Caleb has big dreams and is ready to continue his path in the geosciences. Contact him at caleb.koostra892@topper.wku.edu.

KEGAN McCLANAHAN | LEAD WET CHEMIST & FIELD ANALYST

Kegan is the lead wet chemist and field analyst (jack of all trades, master of none!), for CHNGES and the HydroAnalytical Lab. He earned his Bachelor of Science in Geology from the University of Cincinnati and a Master’s in Geoscience from Western Kentucky University. His thesis investigated inorganic carbon cycling along the Green River in south-central Kentucky. His research passions revolve around the applications of low temperature stable isotope systems to climate change, karst geochemistry, water resources, and water quality. In his spare time, Kegan enjoys taking drives through the country with classic rock and roll blaring, getting muddy in caves, and exploring the world through overlanding. Contact him at kegan.mcclanahan@wku.edu.

GRAY P'POOL | OFFICE ASSOCIATE

Gray P'Pool is the Office Associate for CHNGES. Yep, she’s the one that drives the day-to-day operations of the Center. She stays busy wrangling and caring for our crazy group, and doesn’t even have time for a photo. In her “spare” time, she enjoys working in her garden, investigating genealogy, and traveling. Gray is our resident animal and nature lover. Her favorite animals are dogs, horses, moose, foxes, squirrels, and birds, but those default to whatever animal is in front of her at the time! Email Gray at gray.ppool@wku.edu.
