Meet Our Team
Dr. George Shillinger, Executive Director
George develops scientific partnerships and leverages data to set conservation priorities, build support in key constituencies and advance protections for turtles at sea.
George has worked in environmental conservation since 1986, including satellite-tracking pelagic species such as sea turtles, billfish, sharks and tuna. As a Great Turtle Race co-founder, he used satellite-tracking data to raise global awareness for critically endangered leatherbacks.
George has a PhD in Marine Biology and an MS in Ecology and Evolutionary Biology from Stanford University, an MBA from the Yale University School of Management and a BA in the Biological Basis of Behavior from the University of Pennsylvania.
Dr. Heather Harris, Wildlife Veterinarian
Heather is a wildlife veterinarian and board-certified specialist in veterinary preventive medicine. She applies an integrative One Health approach to study marine wildlife as sentinels for ocean and human health at the land-sea interface.
Heather conducts sea turtle health assessments, investigates causes of mortality, evaluates toxin exposure, and documents human impacts to sea turtles worldwide. She provides veterinary expertise to local, national, and international partners on safe capture methods, field research techniques, mass stranding events, oil spill response, rehabilitation, and postmortem examinations.
Heather has a DVM in Veterinary Medicine and MPVM in Wildlife Disease Ecology from the University of California, Davis, and a BA in Environmental Studies from the University of California, Santa Barbara. She is a diplomate of the American College of Veterinary Preventive Medicine.
Kayla Horner, Research and Administrative Manager
Kayla provides support to Upwell's sea turtle research and conservation programs.
Kayla's strong organizational skills are bolstered by her professional background in scientific and rescue diving, volunteer experience in marine animal husbandry and academic research on marine habitats around Monterey and the Channel Islands.
She has a BS in Marine Science from California State University, Monterey Bay and is also a certified scuba instructor, lifeguard and CPR/first aid and emergency oxygen provider.
Aimee Doyle, Researcher
Aimee conducts primary research to improve hatchling dispersal models, advises on outreach strategies and creates tools to predict and prevent fisheries interactions with sea turtles.
Aimee's wider research portfolio has focused on the effects of large-scale ecosystem changes on populations of marine organisms. She was a Knauss Fellow with the NOAA NMFS Office of Science and Technology’s National Observer Program.
Aimee has a BS in Marine and Atmospheric Science from the University of Miami in Coral Gables, Florida and an MS in Fisheries Science from the University of Maryland Center for Environmental Science.
Kajsa Williams, Laboratory Assistant
Kajsa assists with processing of barnacles collected from stranded sea turtles for stable isotope studies to learn more about their range and habitat use.
Kajsa is a first-year student at the University of California, Los Angeles aspiring to major in molecular biology.
Dr. Kristin Reed, Operations Director
Kristin builds program strategy and operational capacity to ensure organizational effectiveness, meet conservation objectives and sustain partnerships.
Kristin has conducted research with fishing communities on three continents. She directed the Human Rights Fellowship for the University of California and has consulted on pan-African humanitarian initiatives and campaigns to end illegal wildlife trade in Cambodia.
Kristin has a BS in Foreign Service and a certificate in African Studies from Georgetown University and a PhD in Environmental Science, Policy and Management from the University of California, Berkeley.
Dr. Sean Williamson, Researcher
Sean conducts research to improve the odds for leatherback hatchlings.
He has collaborated with Upwell scientists to prepare leatherback turtle hatchling dispersal field experiments at Pacuare Nature Reserve on the Caribbean coast of Costa Rica. His continuing work with Upwell focuses on building consensus among scientists on efforts to decrease East Pacific leatherback hatchling mortality.
Sean has a PhD in Biology on the ecophysiology of embryonic development in turtles and crocodiles from Monash University, Melbourne, Australia.
Liz Gregg, Development and Communications Coordinator
Liz leads fundraising with institutional donors, and assists with individual donor and board communications to ensure that Upwell's mission and accomplishments are presented to the broader community. Liz has worked in non-profit fundraising and communications for over five years, primarily within the marine conservation field. She has a BA in Botany from UC Santa Cruz and a MS in interdisciplinary ecology with a focus on tropical conservation and development from the University of Florida.
Stephanie Rousso, Researcher
Stephanie develops local partnerships and collects spatial ecology data to advance community-based sea turtle conservation models in Northwest Mexico.
As a wildlife biologist, Stephanie’s work collecting epibionts (e.g., barnacles) from sea turtles is helping to identify high-use habitats. She oversees a network of citizen scientists recording observations of turtles in marine environments.
Stephanie is a four-time Rufford Fellow and has a BS in Biology from California State University, Bakersfield and an MS in Marine Biology from the Center for Marine Science (CICIMAR) in La Paz, Baja California Sur where she is currently a doctoral student.
Nicole Barbour, Research Associate
Nicole studies the migratory movements of sea turtles of different age classes to inform more effective, targeted conservation strategies.
Upwell’s “lost years” partnership with Dr. Helen Bailey at the University of Maryland Center for Environmental Science (UMCES) has supported Nicole’s research tracking leatherback hatchlings in the Caribbean through different tide and wind states.
She has a BS in Biology from California State University, Monterey Bay and is currently a doctoral student at UMCES.
