Peter L. Hagelstein is an associate professor of electrical engineering at the Massachusetts Institute of Technology (MIT), affiliated with the Research Laboratory of Electronics (RLE).
Hagelstein began his career at the Lawrence Livermore National Laboratory, working on high-energy laser and plasma physics from 1981 to 1985.
In 1989, he started investigating cold fusion (also called low-energy nuclear reactions) with the hope of making a breakthrough similar to the X-ray laser.
[2] Hagelstein continued his research activity in the field, chairing the Tenth International Conference on Cold Fusion in 2003.
[4] Following the cold fusion episode, his primary research has shifted to solid-state physics, including the development of new thermoelectric materials.
