Peter L. Hagelstein is a principal investigator in the Research Laboratory of Electronics (RLE) and an Associate Professor at the Massachusetts Institute of Technology (MIT). He received a bachelor of science and a master of science degree in 1976, then a Doctor of Philosophy degree in electrical engineering in 1981, from MIT. He was a staff member of Lawrence Livermore National Laboratory from 1981 to 1985 before joining the MIT faculty in the Department of Electrical Engineering and Computer Science in 1986.
Hagelstein's early work focused on extreme ultraviolet and soft X-ray lasers , relativistic atomic structure and electron collision physics, autoionization and dielectronic recombination processes, plasma population kinetics, radiation transport and large scale physics simulation. He received the Ernest Orlando Lawrence Award in 1984 for his innovation and creativity in X-ray laser physics. While working in the Lawrence Livermore National Laboratory he pioneered the work that later produced the first X-ray laser, which would later become important for the US Strategic Defense Initiative, popularly referred to as the "Star Wars" program.[1]
His recent efforts have included the invention of semiconductor technology that could allow efficient, affordable production of electricity from a variety of energy sources, as well as continuing investigations of low-energy nuclear reactions. Hagelstein is the co-author of a new textbook, Introductory Applied Quantum and Statistical Mechanics, and chaired the Tenth International Conference on Cold Fusion in 2003.[2]
