Meet The Headwaters Team
University of Nevada, Reno
In 2019, Gabriela completed her second Master’s of Science in fungal ecology at the University of Nevada, Reno. She researched the disease dynamics of fatal bat fungal disease, White nose syndrome. While she worked as a graduate student she also worked at UNR’s Museum of Natural History where she taught all ages natural history and science lessons using real museum specimens. She had the unique opportunity to bring these lessons to the Black Rock Desert at Burning Man for the last few years. Previously, she managed a amphibian disease lab in New Mexico where she mentored students in designing research projects and data collection. Gabriela enjoys paring research with learning and has also developed scientific inquiry based curriculum as a part time Truckee Meadows Community College Biology instructor in Reno. She hopes to continue to mentor in science for the rest of her career.
Boise State University
Kerri has her MS in Geoscience from Boise State University, with a focus on geomorphology and landscape change. For her research, she used geochronology and geochemistry to understand how drylands have been influenced by climate change over glacial-interglacial cycles. She works as an environmental scientist, mainly in water and soil quality monitoring and remediation. She has also worked for several outdoor science education programs with students of all ages, and really enjoys the opportunity to teach science in the field. She also likes to backpack, mountain bike, and explore new places.
Ashley M. Pierce is an environmental scientist with a background in atmospheric pollutants, specifically, mercury, ozone, and particulate matter. A Master’s and Ph.D. in Environmental Science gave her experience in environmental measurement and monitoring, requiring extensive field site management, cooperation with multiple agencies, and proficiency with analytical instrumentation, technological systems, data analysis programs, and software. Ashley previously was the grants coordinator for the Headwaters Science Institute and helped develop science programs for K-12 students with a focus on underserved communities. She is currently a AAAS Science and Technology Policy Fellow placed at the National Science Foundation where she works on programs that are cross-disciplinary with a focus on sustainability. Ashley is interested in creating and improving scientific conversations that will lead to collaborative solutions to some of the most pressing current and future environmental problems
University of California, Berkeley
Anna Holmquist is currently a Ph.D. candidate at the University of California, Berkeley in the department of Environmental Science, Policy and Management. Her dissertation focuses upon the interplay of ancient versus modern processes in structuring biodiversity of spiders on the island of Sulawesi in Indonesia. Previously, Anna studied the impact of the urban heat island effect, in which urban areas are hotter than surrounding suburban and rural regions, on communities of spiders living in street trees. Outside of her own research, Anna enjoys encouraging students of all ages in their scientific interests and is passionate about finding effective ways to make science more accessible and more exciting for all. In her free time, Anna likes surfing, backpacking, and playing her upright bass.
University of California, Davis
Aviva is a PhD candidate at the University of California, Davis, where she studies the genetics of North America’s largest freshwater fish, the white sturgeon. Her work focuses on using molecular genetics to advance our understanding of sturgeon population dynamics with the goal of improving conservation efforts for endangered populations of white sturgeon. She also helped start a program at UC Davis called GOALS (Girls’ Outdoor Adventures in Leadership and Science) a free two-week summer backpacking and field science expedition in California’s Sierra Nevada mountains for high school girls. In her free time, she enjoys rock climbing, mountain biking, backpacking with her dog, and gardening. She loves mentoring young scientists, and is excited to be a part of Headwaters Science Institute!
University of California, Davis
Hanna Kahl is a Ph.D. student at UC Davis in the Department of Nematology and Entomology, National Science Foundation Graduate Research Fellow, and co-lead of Women in Data’s Sacramento Chapter.

Important notes about our staffing and emergency policies:
Headwaters Science Institute is committed to maintaining the highest safety and security standards for our programs. When your children are in our care, you can trust that they are safe.
- All employees and contractors are background checked before they start working with us. We use a national-level background check program called National Crime Search (nationalcrimesearch.com) that searches all states and county records for any criminal records, sex & violent offenders, and includes a terrorist search.
- Our staff members are all first-aid and CPR certified. Some are Wilderness First Responder certified as well.
- We have a safety plan for every field site we use and know where the nearest fire station is located. We are never more than a few minutes walk to the nearest road.
- In the unlikely event of an emergency, we always work in areas that are easily served by 911. Our field site on Donner Summit is less than 2 miles from the nearest fire station with full-time EMT services and the hospital is a short 10-minute ride away.
