Zachary Beattie, Ph.D.

  • Assistant Professor of Neurology, School of Medicine
  • ORCATECH, School of Medicine

Biography

While a graduate student at OHSU, Dr. Beattie developed a new technology with the ability to detect sleep apnea using non-contact sensors. After completing his Ph.D. in Biomedical Engineering, Dr. Beattie accepted a Research Scientist position at Fitbit where he innovated new features for Fitbit wearables, working as project lead for several Fitbit research projects including the recently released Fitbit Sleep Stages feature, which has been used to collect over 6 billion nights of sleep data.  In 2017, Dr. Beattie returned to OHSU to join the team at the Oregon Center for Aging and Technology.

In his free time, Dr. Beattie enjoys spending time with his three boys and exploring the outdoors through camping, hiking, and running.

Research

Currently as lead data scientist at ORCATECH (Oregon Center for Aging and Technology), Dr. Beattie is focused on data validity, provenance and integrity for the ORCATECH platform.  The ORCATECH platform consists of digital sensors placed in the homes of elderly individuals that are used to collect a variety of data (e.g. walking speed, activity levels) about the individuals with the goal of developing digital biomarkers that can be used to facilitate studies of aging and in clinical trials. Dr. Beattie is particularly focused on overseeing data architecture and algorithm development for the NIA and VA funded national CART (Collaborative Aging Research using Technology) Initiative by building out the ORCATECH platform to enable research for multiple investigators ultimately engaging thousands of homes across the U.S.
