About the Author

Mark Geanacopoulos

Mark Geanacopoulos caught the science bug after a career as an educator in alternative schools for troubled adolescents in Cambridge, Massachusetts. He went on to receive a Ph.D. in Biochemistry from the University of Virginia in 1993, where he studied the signaling mechanisms that control the action of our circulating blood platelets in forming blood clots. His subsequent work at the National Institutes of Health focused on the proteins that bind to DNA and modulate gene expression. Having discovered in the course of his laboratory research a passion for the communication of science, he is embarking on a career in science journalism. He lives in Olney, Maryland with his wife and daughter.
