Dr. Austin BairdAustin J. Baird, PhD
Research Assistant Professor
Division of Healthcare Simulation Science

Dr. Baird received his PhD in applied mathematics as it relates to heart tube electrophysiology and fluid dynamic modeling at the University of North Carolina, Chapel Hill. At his post doc training at Duke University he worked with Dr. Anita Layton on physiological modeling of the kidney, specifically how the reabsorptive and autoregulatory mechanism change as a function of venous return pressure abnormalities. At UNC Dr. Baird was an HHMI and future faculty scholar and was responsible for creating a new curriculum on dynamical systems modeling for non-math majors. At Duke he taught multiple courses on differential equations in the engineering department. He then left academia to work in industry at Applied Research Associates where he was the PI of the BioGears project for 4 years.

At ARA Dr. Baird was the PI on multiple DoD funded medical modeling and simulation grants and contracts related to burncare, TBI modeling and prolonged field care training. His team was awarded the federal IT innovation award for their work on the BioGears project. At ARA he was promoted to Senior Engineer and was denoted a distinguished member of the technical staff. He eventually became the biomedical engineering, modeling, and applications (BEMA) group leader where he oversaw and created a vision for biomedical work at the southeast division of the company. At ARA he co-led the internship program and was responsible for ARA’s involvement in the Google Summer Code project. Interns who he advised now work at General Motors and Becton Dickerson as engineers.

Dr. Baird’s research focuses on mathematical modeling of biological systems, specifically mathematical models in physiology in the context of whole-body patient responses. He aims to connect multiple spatial and time scales which determine dynamics of biological systems at the molecular and system levels to create a picture of the larger patient response to injury. His work also focuses on carful validation of biological systems, specifically their response to perturbations such as trauma and the problem of connecting experimental data to computational models. He believes in cross disciplinary collaborations and aims to nurture those groups at UW.

Austin is on the leadership circle in the healthcare systems modeling and simulation affinity group, part of the Society of Simulation in Healthcare (SSH). He’s an active member of the Society of Industrial and Applied Mathematics (SIAM) and the NIH multiscale modeling group.
