Eureka Joshi is an environmental scientist whose research focuses on studying the ecological impacts of biosolids and reclaimed water reuse in terrestrial ecosystems. She received her Ph.D. in Environmental Science from the University of Idaho, M.S. in Environmental, Safety and Health Management with an emphasis in Environmental Management from The University of Findlay, and B.S. in Microbiology from St. Xavier’s College, Kathmandu. Before joining Southwestern University, she was the Thomas McKenna Meredith ’48 Postdoctoral Fellow in Environmental Science at Trinity College, Hartford. When she isn’t teaching or doing research, she enjoys nature, art, and spending time with her cat Audrey Hepburn.

CV

Eureka has collaborated with waste reuse facilities, Native American tribes, state and federal agencies, and landowners to conduct research on forest responses to municipal reclaimed water. She studied impacts on forest growth and vegetation diversity, drainage and soil nutrient leaching potential, and soil biological responses. As a postdoctoral fellow, she collaborated with regional waste reuse facilities in New Hampshire to study the impacts of biosolids land application on soil carbon, nitrogen and phosphorus cycling. At SU, she continues to closely work with regional facility managers, regulators, and SU undergraduate scholars to explore the legacy effects of biosolids land application on soil health in Texas ecosystems.
