Who We Are
Jeffrey Kaye, M.D., is the Layton Endowed Professor of Neurology and Biomedical Engineering at Oregon Health & Science University. He is the director of ORCATECH and director of the NIA - Layton Aging and Alzheimer’s Disease Center. Dr. Kaye’s research has focused over the past two decades on understanding healthy aging using a variety of approaches ranging across the fields of genetics, neuroimaging, physiology and continuous activity monitoring. He leads several longitudinal studies of aging including the ongoing Oregon Brain Aging Study, the Intelligent Systems for Detection of Aging Changes (ISAAC) study and the ORCATECH Living Laboratory. The latter studies use pervasive remote sensing and computing technologies for continuous assessment of health and function among older adults in their homes. Recently, Dr. Kaye received a NIH award to study how real time in-home passively assessed activities (“Ambient Independence Measures” or AIMs) may be used to prevent transitions to higher levels of care. Also recently, Dr. Kaye has begun a new NIH funded Canadian, US, and UK program project in collaboration with three other principal investigators to pursue the “Integrated Analysis of Longitudinal Studies of Aging” (IALSA). IALSA seeks to create a common international harmonization platform for longitudinal studies of aging in order to advance integrative, interdisciplinary, and cross national approaches to research on aging, cognition, personality, and health. Dr. Kaye has received the Charles Dolan Hatfield Research Award for his work. He is listed in Best Doctors in America. He serves on many national and international panels and review boards in the fields of geriatrics, neurology and technology including as a commissioner for the Center for Aging Services and Technology (CAST), Chair of the International Society to Advance Alzheimer’s Research and Treatment (ISTAART), a member of the Advisory Board of AgeTech West, and on the Leadership Council of the Network on Environment, Services and Technologies for the American Society on Aging. He is an author of over 300 scientific publications and holds several major grant awards from federal agencies, national foundations and industrial sponsors.

Ms. Zitzelberger was graduated from the Ohio State University with a Bachelor of Arts in Women’s Studies and began her research career recruiting for the NIH Women’s Health Initiative at The Ohio State University Medical Center. She moved to Portland in 2000 to work with the Layton Aging & Alzheimer’s Disease Center at Oregon Health & Science University and directed the Dementia Prevention Study, a primary prevention trial of Gingko biloba in healthy seniors over age 85. She received her Master of Public Health in Health Administration and Policy from Portland State University in 2003.
Kathy Wild, Ph.D., is an ORCATECH investigator with a research focus on elder care and healthcare utilization transitions. Dr. Wild is an associate professor in the OHSU Department of Neurology with special interests is in cognitive impairment and dementia. She received her doctorate in 1988 from the Ferkauf Graduate School of Psychology - Yeshiva University, New York. She has been collaborating with other members of ORCATECH in research on the use of in-home technology to prolong safe and independent living. Other research interests include computer-based assessment to detect early changes in cognition, and impaired insight as it relates to decision making in persons with mild cognitive impairment and dementia.
Hiroko Dodge, Ph.D., is an ORCATECH investigator who joined the NIA-funded Oregon Alzheimer's Disease Center (OADC) at OHSU as a data core director in 2008. Dr. Dodge’s work focuses on refining statistical methods which allow us to capture the decline leading to dementia at the earliest stage of the disease, examining lifestyle and environmental factors leading to healthy cognitive aging, and conducting behavioral prevention trials against cognitive decline. She is currently examining whether simulations through social interactions could improve cognitive functioning.
Chad Hagen, M.D., is an biomedical engineering investigator for ORCATECH. Dr. Hagen's research focus has been improvement in the definition and detection of sleep disorders with an emphasis on sleep apnea and sleep fragmenting disorders. There is heightened need for less expensive and non-obtrusive technology for the diagnosis and treatment of sleep disorders. Over the last four years, his group has developed technology for the unobtrusive assessment of sleep apnea both in the laboratory and in the comfort of patients’ own homes. Research collaboration with biomedical engineers combined with his work as clinician and director of a busy academic sleep disorders program with thousands of sleep patient encounters per year puts him in a unique position to aid the translation of sleep research to the point of care.
Zach Beattie, Ph.D., is a senior research associate in psychiatry graduate researching the use of force sensors placed under the supports of the bed to unobtrusively detect sleep apnea and other health characteristics.
Daniel Austin, Ph.D., is a research instructor in the Department of Neurology. Dr. Austin received the B.S. degree in Electrical Engineering Technology from the Oregon Institute of Technology in 2006, the M.S. degree in Electrical Engineering from the University of Southern California in 2008, and the Ph.D. degree in Biomedical Engineering from the Oregon Health & Science University in 2013. His current research is in the general area of behavior modeling for health care applications using various types of computational modeling (nonlinear regression, signal processing, machine learning, etc.) with a specific emphasis on fusing multiple data streams captured from in-home sensor networks into a cohesive modeling framework to measure and predict cognitive, physical, and functional decline.
