Center Director -  Jessica Halofsky

Center Director Jessica Halofsky

E-mail: Contact Jessica
Phone: 360-753-7677

Jessica's research is focused on assessing potential effects of climate change on forest vegetation and disturbance regimes, using both modelling and field-based approaches. She facilitates development of climate change vulnerability assessments and adaptation plans for national forests and other partners across the western United States. Her current focus has been on developing tools to facilitate application of vulnerability assessment and adaptation information in management processes. She holds B.S. from Bucknell University (1999), a M.A. from Penn State University (2002), and a Ph.D. in Forest Science from Oregon State University.

Jessica Schlarbaum is an ORISE Science Communications fellow with WWETAC. She received a M.S. from the University of California, Davis in Avian Sciences in 2020, studying the nesting ecology of American Kestrels in agricultural habitats in the Central Valley of CA. During graduate school, she taught an introductory biological sciences course, assisted farmers with natural pest management using raptors, and worked at a raptor rehabilitation facility educating the public about human-raptor conflicts. After graduating, Jessica became the Communications Manager at a non-profit wildlife center in Santa Fe, New Mexico. Throughout all her experiences, science communication has been a constant and she is eager to continue making scientific information accessible to a diverse audience.

As Coordinator Dr. Holly R. Prendeville is responsible for developing and maintaining relationships, communicating use and availability of climate change tools, coordinating grants and agreements, as well as developing and implementing strategies for producing priority outcomes for the Northwest Climate Hub. Holly has been the Coordinator since 2016. As a Forest Service Research Geneticist, Holly collaborated with other scientists to investigate the efficacy of seed zones developed for bluebunch wheatgrass in the Intermountain West. This work provides guidelines to facilitate restoration using locally adapted material that will be resilient in the face of climate change. As a Postdoctoral Research Associate at the University of Virginia, Holly investigated how plant reproductive phenology varies among populations across a latitudinal gradient in the eastern US. Holly obtained a Ph.D. from the University of Nebraska-Lincoln in Ecology, Evolution and Behavior studying the ecological risks of virus-resistant transgenic squash by examining the effects of virus and the virus-resistant transgene in wild squash.
