Dr. Martin Blank has Ph.D. degrees from Columbia University in physical chemistry, and from the University of Cambridge in colloid science. He is a retired Associate Professor of Physiology and Cellular Biophysics at Columbia University Medical School, and now a Special Lecturer in the department. His research includes health effects of electromagnetic radiation.
In this 2 minute video, Dr. Blank briefly describes the cellular effects of electromagnetic radiation. "Electromagnetic fields interact with biological tissue because biological tissue is made of up charged particles, and we have show in our lab in our study of the responses of various enzymes that they respond to electromagnetic energy, and the electrons can be made to move differently [under the influence of electromagnetic fields] than they would normally."
