Jeff Iliff

Dr. Jeffrey Iliff is an Assistant Professor in the Department of Anesthesiology and Perioperative Medicine at Oregon Health & Science University. He also holds a joint appointment as an Adjunct Assistant Professor in the Center for Translational Neuromedicine at the University of Rochester Medical Center.

Dr. Iliff's research follows two main paths. This first is the exploration of how the brain's support cells, called glia, contribute to maintaining the proper environment for neuronal function and how their failure in conditions like vascular dementia, stroke and traumatic brain injury leads to neurodegeneration. The second seeks to define the basic cellular mechanisms by which brain blood flow is coordinated up and down the vascular tree.

Dr. Iliff grew up in Sequim, Washington and completed his doctoral training in 2009 in the Department of Physiology and Pharmacology at OHSU. He then completed two years as a postdoctoral fellow at the the University of Rochester Medical Center in Rochester, NY, where he was promoted to a research faculty position in 2012. Dr. Iliff joined the department in 2013.

When not doing research, Dr. Iliff enjoys hiking, reading, and being with his family.

Katie Schenning, MD; Assistant Professor

Katie Schenning

(Mentor: Michael Hutchens, MD; Senior Co-Mentor: Sharon Anderson, MD) Dr. Schenning completed MD and MPH training at the University of Wisconsin School of Medicine and Public Health before joining our Oregon Scholars Program in 2010. She is currently evaluating mechanisms for protection of the kidney from hypoxic injury. Dr. Schenning was recently selected as a recipient of the 2012 Renal Specialty Award, which recognizes excellence in critical care research. This award was based on her research abstract on the protective effects of hyperglycemia on hypoxic injury in glomerular endothelial cell monolayers that was accepted for oral presentation at the 2012 Society of Critical Care Medicine Meeting. She has also been elected to serve as a member of the ACGME Anesthesiology Residency Review Committee, which defines the rules for training of interns, residents, and fellows in anesthesiology and then assess whether individual programs are in compliance with those rules. Only one resident is chosen amongst the more than 3000 anesthesiology residents in the US to serve on this committee. Dr. Schenning plans to submit a Research Fellowship Grant application to the Foundation for Anesthesia Education and Research (FAER) in 2012.

Eric Schnell, MD, PhD; Staff Anesthesiologist

Eric Schnell, MD, PhD

Dr. Schnell received a B.A. degree in Psychobiology from Harvard University, an M.A. degree in Pharmacology from the University of Cambridge (UK), and his Ph.D. degree in Neuroscience from the University of California, San Francisco. He subsequently completed medical school, an internal medicine internship and anesthesiology residency at UCSF, serving as a chief resident in his final year. He joined the Portland VA Anesthesiology Service and OHSU Department of Anesthesiology and Perioperative Medicine in 2008, and was appointed to the Neuroscience Graduate Program faculty in 2013.

Dr. Schnell’s main research interest is to understand how synapses between neurons in the central nervous system are formed, maintained, and regulated, with the eventual goal of using these insights to develop therapeutic strategies for neurologic disease. His recent work focuses on the study of adult neurogenesis, which is the generation of new neurons in the adult brain. This process is an important aspect of recovery from acute neurologic injuries such as traumatic brain injury (TBI) and ischemic stroke. As these newborn neurons must be integrated into existing neuronal circuits in order to contribute to information processing, an understanding of how synapse formation onto these cells is regulated and modulated will have profound clinical implications. Dr. Schnell is interested in understanding how post-injury medical care influences the magnitude and efficacy of post-injury neurogenesis, with the goal of preserving and possibly enhancing the beneficial contributions that these cells make to functional recovery.

Laura Villasana, PhD; Assistant Professor

Laura Villasana

She recently completed her PhD in the Behavioral Neuroscience Program at OHSU in December 2011. Dr. Villasana's dissertation research examined the role of apoE-isoform on the cognitive function of adult female mice following cranial irradiation. Currently, she is a postdoctoral fellow under the mentorship of Dr. Eric Schnell in the APOM Department. Her research project involves examining the integration of new, adult born neurons generated after traumatic brain injury (TBI). It is well established that the rate of constitutive adult neurogenesis is substantially increased after TBI, and it is believed that these newly born neurons integrate into the brain and contribute to cognitive recovery. However, because network integration of new neurons after other types of brain pathology follows an atypical (and possibly dysregulated) pattern, we are interested in studying the maturation and integration of these new neurons after TBI.

Dr. Villasana is also a research trainee, being mentored by Dr. Eric Schnell, MD and senior co-mentor Dr. Nabil Alkayed, MD, PhD.
