Who needs old growth forest? Multitaxa biodiversity surveys of forests in the Pacific Northwest

Dr. Taal Levi received his PhD from University of California Santa Cruz. He is currently an Associate Professor at Oregon State University in the Department of Fisheries, Wildlife, and Conservation Sciences. Dr. Levi researches ecological consequences of wildlife overexploitation, population dynamics in a changing climate, and quantitative methods to address applied problems. 


The Tomato Blues: From Germplasm to Global Spread, the Odyssey of High Anthocyanin Tomatoes

Dr. Jim Myers received his PhD from University of Wisconsin-Madison. He is currently a Professor at Oregon State University in the Department of Horticulture. Dr. Myers researches crop adaptation to organic production systems, enhancing human nutrition in vegetables, and incorporating resistance to the major pathogens.

Ecological and evolutionary dynamics of foliar fungal endophyte community assembly and host associations

Dr. Jana U'ren received her PhD from University of Arizona. She is currently an Assistant Professor at University of Arizona in the Department of Biosystems Engineering. Dr. U'ren researches assembly of plant-associated fungal communities, how community structure and diversity impacts ecosystem function, and the evolutionary dynamics of fungal symbiont evolution in the context of closely related pathogens and saprotrophs.

Quantitative, functional, and comparative genomic tools for American chestnut restoration

Dr. Jason Holliday received his PhD from University of British Columbia. He is currently a Professor at Virginia Tech in the Department of Forest Resources and Environmental Conservation. Dr. Holliday researches genetic determinants of complex adaptive traits, such as timing of growth and dormancy transitions, tolerance to temperature extremes and drought hardiness, using genotype-phenotype association studies and landscape genomics.

Breeding hazelnuts resistant to eastern filbert blight

Dr. Shawn Mehlenbacher received his PhD from Cornell University. He is currently a Professor at Oregon State University in the Department of Horticulture. Dr. Mehlenbacher researches hazelnut breeding, with emphasis on eastern filbert blight and sustainability, in addition to genetic control and markers for resistance cultivars.


What role should forests play in climate mitigation?  

Dr. Jacob Bukoski received his PhD from University of California, Berkeley. He is currently an Associate Professor at Oregon State University in the Department of Forest Ecosystems & Society. Dr. Bukoski researches ecology and management and restoration of forests of the tropics and North America with respects to applied approaches and data-driven tools to inform environmental decision-making.

The origins and endpoints of beneficial intracellular bacterial infections

Dr. John McCutcheon received his PhD from Washington University in St. Louis. He is currently an Investigator of the Howard Hughes Medical Institute, Professor in the School of Life Sciences, and Associate Director of the Biodesign Center for Mechanisms of Evolution at Arizona State University in the Department of Horticulture. Dr. McCutcheon researches evolutionary cell biology and symbiosis between endosymbionts and host cells with emphasis on genome stability and functional integration of the process of organelle formation.
