Michael Wysession

Michael Wysession received his Ph.D. in geophysics from Northwestern University in 1991. He is an Associate Professor in Earth and Planetary Sciences at Washington University in St. Louis, Missouri. His area of specialization is using seismic waves to explore Earth’s interior. Dr. Wysession is an author on more than 50 scientific publications. For his research, he was awarded a Packard Foundation Fellowship, and in 1996 was awarded a Presidential Faculty Fellowship at the White House. He also has created educational simulations to accurately show how seismic waves propagate.


David Frank

David Frank completed his Ph.D. at Purdue University. For the last ten years he has been the head of the Physical Sciences Department at Ferris State University in Big Rapids, Michigan. He has taught general chemistry courses for science majors and for allied health students. With the assistance of his colleagues, he helped develop a new B.A. program in biochemistry. He has taught students in the university’s Math/Science/Technology program, which enrolls gifted high school students. Recently he has worked with Michigan’s “Connecting With the Learner” group, which produced a toolkit to help elementary and secondary teachers address diversity issues in the classroom.


Sophia Yancopoulos

Sophia Yancopoulos received her Ph.D. in physics from Columbia University. She has done postdoctoral research in astronomy at Yale University and in biophysics at the Mount Sinai School of Medicine. She considers teaching to be a vital and exciting part of her experience, having taught at Barnard College, Vassar College, the Stevens Institute of Technology, and Columbia University, as well as at Bronx High School of Science. She has worked on a neutrino oscillations experiment at Fermi National Laboratory, conducted experiments on acoustic modeling, and analyzed data on extreme astrophysics of neutron stars. She currently teaches in the physics department at Manhattan College and in their graduate program in biotechnology.
