Renewable energy, particle physics, science education, physics and society, energy and environmental topics.
Robert Ehrlich is currently a professor of physics at George Mason University and has chaired the Physics and Astronomy department there for many years. He began his career after receiving a BS in physics from Brooklyn College in 1959, and PhD in physics from Columbia University in 1964 in experimental particle physics, having worked on the Nobel Prize winning "two neutrino" experiment. Altogether, he has authored or edited twenty books and close to 100 articles in areas including particle physics, science education, physics & society, and energy & environmental topics.
His recent research interests lie in the area of energy, especially renewable energy. In the last few years at Mason he started a renewable energy minor, and a new graduate program in the subject. He has recently published a textbook, Renewable Energy: A First Course.
