Meghan Martin-Wintle, PhD, Conservation Biologist

Dr. Meghan MartinDr. Meghan Martin-Wintle is a conservation biologist and President of PDXWildlife, a Postdoctoral Researcher at San Diego Zoo Global’s Institute for Conservation and Research and a Research Associate at the Oregon Zoo Conservation and Research Department. Meghan holds a B.A. in Biology from Reed College and an M.S. and PhD in Biology from Portland State University. Her graduate research focused on the effects of mate choice and personality in ex-situ conservation captive breeding programs for Columbia Basin pygmy rabbits and giant pandas. Her PhD was a multi-institutional collaboration between the Oregon Zoo, San Diego Zoo, and China Conservation and Research Center for the Giant Panda. She has also worked with Asian elephants, polar bears, endangered freshwater mussels, and rhesus macaques.  She has authored or co-authored numerous scientific papers and has received multiple grants and awards. The major focus of Dr. Martin’s current research is on mate preference, social and behavioral aspects of captive breeding, and the role of personality and stereotypical behavior in reproductive performance. Meghan spends most of her time at PDXWildlife on the Giant Panda project.  Highlights of her career have been developing international internships for students to obtain valuable conservation experiences at the global level, public outreach on conservation and endangered species, and improving breeding programs in captivity.  Meghan whole-heartedly believes in PDXWildlife’s motto, “conserving species through research, community education, and science” and hopes to pass this passion onto her students, the global scientific community, and the general public.

• Nathan J.P. Wintle, M.S., Biologist

Nate Wintle, M.S.Nathan serves PDXWildlife as Deputy Director & Treasurer. He received his B.S. and M.S. in Biology from Portland State University, where he developed a novel method for analyzing mercury in marine mammals. Nathan’s previous projects include contaminant monitoring in Antarctic Nothothenioid fish, avian surveys in the Gulf of Mexico during the all phases of the B.P. Oil Spill, Methylmercury analysis of panda hair and food sources, and marine mammal organochlorine studies. Nathan has authored and co-authored several scientific publications.  Nathan’s current research is focused on giant panda mercury levels and monitoring hormones in feces in captive pandas from Sichuan, China. As a collaborator on the giant panda project with Dr. Meghan Martin, Nathan oversees each project, frequently traveling to China, welcoming each intern into the country. When Nathan is not working, you can usually find him hiking or fishing with his wife and daughter.


• Sharon Glaeser, M.S., Biologist

Sharon Glaeser

Sharon Glaeser is a biologist for PDXWildlife and serves as a Director. She is also research associate in the Oregon Zoo Conservation and Research Department. Sharon holds a B.S. in Electrical Engineering from Oregon State University and an M.S. in Biology from Portland State University. Her graduate research focussed on acoustic communication of Asian elephants at the Oregon Zoo and in Thailand. She also developed a collaborative program between Portland State University and federal and state agencies and trained students to perform sea lion predation observations on two river systems. The major focus of Sharon’s current research is on the assessment of well-being and reproduction of Asian elephants through hormone and behavior monitoring. Sharon is very involved in the international elephant community of researchers, veterinarians, handlers, conservationists, and managers. Highlights of her career have been the relationships with people dedicated to the care and conservation of imperilled species. Sharon believes that the care and conservation of species requires an understanding of the complexity of the issues and our role as individuals and a community.

• Hannah Prather, PhD Candidate, Biologist

Hannah Prather is a field biologist for PDXWildlife. She holds a B.S. in Natural Resources from Oregon State University and is currently a PhD candidate in the Biology program at Portland State University. Her graduate work focuses on urbanization impacts on tree canopy epiphyte biodiversity and function in the Pacific Northwest. She has received a number of grants and was awarded the competitive Doctoral Dissertation Improvement Grant from National Science Foundation for her graduate studies. She has worked previously as a certified arborist and has experience in a diversity of field-based projects studying spotted owls, lichens, bryophytes and forest ecology. She has worked internationally developing K-12 science inquiry education in Central America and has completed two field seasons in Antarctica studying polar lichen and bryophyte communities. Her interests are in combining research, community education and science to better  understand and promote species conservation in a rapidly urbanizing world.

• Diana Dishman, M.S., Conservation Biologist

Diana DishmanDiana Dishman is a conservation biologist at PDXWildlife.  She holds a bachelor’s in Organismal Biology from Scripps College and a master’s degree in Biology from Portland State University.  For her graduate research she studied the genetic substructure of the Pacific harbor seal populations along the coasts of Washington and Oregon.  She has studied captive primate behavior, metals toxicity in aquatic species, marine mammal population genetics, and she has worked with international NGOs to conserve endangered marine mammals and their critical habitats. Diana is currently working with population modeling as a data analyst. Diana is interested in promoting wildlife conservation in local communities and institutions through grass-roots research, training and outreach projects.
