Robert Ehrlich is a recently retired Physics professor at George Mason University. His current research interest is in finding evidence for the reality of faster-than-light particles -- specifically tachyonic neutrinos. (Click to get details on this research).

He is also interested in renewable energy, and promoting renewable energy education – see, for example his junior level 2013 textbook Renewable Energy: A First Course, and his course web site PHYS 331 Fundamentals of Renewable Energy. In view of these research interests, and his recent retirement, Ehrlich is available to give physics colloquia on either subject. A complete list of his publications can be found on his resume. You may also be interested in a 7 min interactive explanation of relativity for the layperson: “Relativity: Adventures of Albert and Marie,” which was a finalist in the 2005 Pirelli Relativity Challenge. In his spare time, Ehrlich is hopelessly addicted to the game of Go,
