Peter L. Hagelstein

Professor Peter L. Hagelstein is an Associate Professor of Electrical Engineering at the Massachusetts Institute of Technology (MIT) in the Department of Electrical Engineering and Computer Science (EECS). He is a Principal Investigator in the Research Laboratory of Electronics (RLE). Hagelstein earned his B.S., M.S., and Ph.D. in electrical engineering from MIT in 1976, 1976, and 1981, respectively. Prior to joining MIT in 1986, he was a staff member at Lawrence Livermore National Laboratory (1981-1985).

His research spans EUV/soft X-ray lasers, relativistic atomic structure, plasma physics, and low-energy nuclear reactions (LENR), including cold fusion. He co-authored the textbook *Introductory Applied Quantum and Statistical Mechanics* and chaired the 2003 Tenth International Conference on Cold Fusion. Hagelstein’s recent work focuses on semiconductor-based energy conversion technologies and thermal-to-electric power generation from waste heat.

He received the 1984 Ernest Orlando Lawrence Award for innovations in X-ray laser physics. His group, the Energy Production and Conversion Group, explores novel energy systems and materials. Notable contributions include studies on the lossy spin-boson model and thermal diode technologies.
