He has a particular focus on insights and interventions that can mitigate loneliness and social isolation as a suicide prevention strategy.
In current and recent work funded by the VA, he conducted a randomized controlled trial of VA S.A.V.E., a form of “gatekeeper training” designed to help family and friends assist military veterans at risk for suicide, and he is also leading a pragmatic trial of Caring Contacts in older veterans who have chronic medical or psychiatric conditions and limited engagement in the VA. He also maintains interests in leveraging social media in health services research and recently has helped lead an evaluation of digital ads used in VA’s “Keep It Secure” suicide prevention campaign, which focuses on firearms safety. Finally, Dr. Teo is an international expert in a severe form of social withdrawal called hikikomori, about which more information is available on his webpage. He completed his education and training at Stanford University, University of California San Francisco, and University of Michigan.

Cydni Williams, M.D., M.C.R. (other contributor; Pediatrics) is an Associate Professor and Pediatric Critical Care Physician at OHSU who specializes in pediatric neurocritical care (children with brain injuries and illnesses requiring intensive care unit admission). Dr. Williams is the Director of the Pediatric Critical Care & Neurotrauma Recovery Program (PCCNRP) where she leads a multidisciplinary team to help children and families journey through recovery from inpatient hospitalization to years after hospital discharge. Children who survive a PICU admission experience challenges not only associated with their primary ICU condition and concomitant treatment, but also a collection of physical, cognitive, emotional, and social symptoms. This assortment of symptoms has been named post-intensive care syndrome (PICS) and can impact both pediatric patients (PICS-p) and their families (PICS-f). Dr. Williams has expertise in patient outcomes after critical care including PICS and sleep disturbances, both providing clinical care and leading research focused in these areas.
