Thomas Heldt

Core Faculty


  • Associate Professor in Electrical and Biomedical Engineering, Institute for Medical Engineering and Science and Electrical Engineering and Computer Science, Massachusetts Institute of Technology


Thomas Heldt joined the MIT faculty in 2013 as Hermann L.F. von Helmholtz Career Development Professor in the Institute for Medical Engineering and Science and as Associate 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 began his studies of physics and medicine at Johannes Gutenberg-Universität, Mainz, Germany. He received the MS and MPhil degrees in Physics from Yale University and the PhD degree in Medical Physics from the Harvard University-MIT Division of Health Sciences and Technology in 2004. He completed his postdoctoral training with the Laboratory for Electromagnetic and Electronic Systems at MIT before he co-founded and co-directed (with George Verghese) the Computational Physiology and Clinical Inference Group at RLE.


  • PhD in Medical Physics, Health Sciences and Technology, MIT, 2004
  • MS and MPhil in Physics, Yale University


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.
