ABOUT THE RESEARCHER

OVERVIEW

Dr. Pienaar is actively engaged with architecting novel approaches to computation in medicine – in particular image processing and AI. He leads a team within the Fetal Neonatal Neuroimaging and Developmental Science Center that has created an open source / open science platform called ChRIS that allows for advanced research and clinical computation to occur in the hybrid cloud. Dr Pienaar and team are passionate about open solutions to medicine and in actively bridging the gap between research computation and clinical practice to better inform patient care and outcomes.

Dr. Pienaar is also engaged in research endeavors examining the internal tractography of the human brain, and applying information processing theory to how the brain itself is organized.

BACKGROUND

Dr Pienaar completed a Doctoral Degree in Biomedical Engineering at the Cleveland Clinic Organization where he conducted research on using Artificial Intelligence to potentially help paraplegic patients stand up again through coordinate muscle stimulation.

Currently he is the Technical Director of the FNNDSC at BCH, where he overseas the compute infrastructure of the Center, as well as leads a team developing new and novel platforms to bringing complex computation to the clinical front lines.
