Thomas Heldt

W.M. Keck Career Development Professor in Biomedical Engineering
Associate Professor of Electrical and Biomedical Engineering


Thomas Heldt joined the MIT faculty in 2013 as Hermann L.F. von Helmholtz Career Development Professor in the Institute for Medical Engineering & Science and as Assistant Professor of Electrical and Biomedical Engineering with the Department of Electrical Engineering and Computer Science. Additionally, Thomas is a Principal Investigator with MIT’s Research Laboratory of Electronics (RLE).

Thomas studied Physics at Johannes Gutenberg University, Germany, at Yale University, and MIT. In 2004, he received the PhD degree in Medical Physics from MIT's Division of Health Sciences and Technology and commenced postdoctoral training at MIT's Laboratory for Electromagnetic and Electronics Systems. Prior to joining the faculty, Thomas was a Principal Research Scientist with the RLE, where he co-founded and co-directed (with Prof. George Verghese) the Computational Physiology and Clinical Inference Group.

Thomas's research interests focus on signal processing, mathematical modeling, and model identification to support real-time clinical decision making, monitoring of disease progression, and titration of therapy, primarily in neurocritical and neonatal critical care. In particular, Thomas is interested in developing a mechanistic understanding of physiologic systems, and in formulating appropriately chosen computational physiologic models for improved patient care. His research is conducted in close collaboration with colleagues at MIT and clinicians from Boston-area hospitals.
