Leah Jackson hails from a variety of places, but most recently from the West Texas Oil Patch. She earned her undergraduate degree in geology at Sam Houston State University in Huntsville, Texas. Her thesis research involved hydrogeochemically characterizing epikarst processes in telogenetic karst systems within the Pennyroyal Sinkhole Plain in South-Central Kentucky (boy, that’s a mouth-full!). Before pursuing her graduate degree at WKU, Leah published a women’s fiction novel called Sweetwater Farm. She hopes one day to be an instructor for clean water living and climate change mitigation tactics via the development and implementation of education and practicality programs through the PeaceCorps. But, for now, she is working on her Ph.D. in the great state of Michigan.

Oh, and then there’s time spent being a chicken keeper…he and his wife have 23 chickens which they keep for eggs.


Nick came to CHNGES from Burkesville, KY. While at the Center, he investigated aquifer processes and evolution in the karstic groundwater systems of Warren County, KY with a specific focus on the Lost River karst aquifer. His aim was to characterize the physical and chemical conditions present during storm flows through the use of high-temporal-resolution data loggers, field sampling of chemical parameters, and computational methods. His purpose was to further understanding of local groundwater systems for city planners, residents, and businesses. Currently, Nick serves as an Environmental Scientist for the Kentucky Department of Natural Resources, where he is responsible for writing cumulative hydrologic impact assessments for watersheds impacted by coal mining, as well as reviewing and critiquing acid mine drainage remediation plans, groundwater monitoring plans, subsidence control plans for underground mines, and general mining permit applications. And in his spare time…he moonlights as a wildland firefighter through the Division of Forestry and US Forest Service. Nick has played rugby for more than ten years, including 3 years at WKU, and is an avid whitewater kayaker. Contact him at


Jason “Jay” Lively is from Wilbraham, Massachusetts. His thesis research focused on understanding the mechanisms behind ion exchange and selectivity in micro- and nano-porous silicate materials. He is also interested in finding ways that these materials can be applied in industry, medicine and in environmental remediation. In fact, he has left us to work in the pharmaceutical industry using the chemical and technological skillsets he learned during his thesis. We are proud to know he may just be the next person to have a medicine breakthrough. Fun fact, Jay has a love-hate relationship with coffee. It’s his life force, but his wallet hates it…
