Johanna Austin, Ph.D.

Johanna Austin, Ph.D., is a post-doctoral research fellow in the Department of Neurology. She received her Ph.D. in Biomedical Engineering in 2015 for her work developing models and algorithms to assess in-home activities associated with loneliness and related behaviors. Her current research interests include unobtrusive, longitudinal measurement of in-home behavior with applications to healthcare. She is especially interested in developing techniques to assess the loneliness and depression levels of informal dementia caregivers, which will require the development and testing of devices and algorithms to distinguish the activities of multiple individuals living in the same home.

Chad Hagen, M.D.

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.
