Craig Margulies
Dr. Craig Margulies received his undergraduate education at the University of Pennsylvania, where he earned a BA in Chemistry and Mathematics.  This was supported by a 4 year, Board of Education Scholarship.  He made Honor Society in Chemistry and Mathematics and graduated in 1984.  During his time at Penn, he spent 3 years working at a research lab, where he studied the composition of gallstones.  He spent the summer of 1984 at the Wistar Institute performing Biomolecular research.  His strong interest in mathematics and science led him to pursue a career in medicine.

After graduating from Penn, he enrolled in the Medical College of Pennsylvania, where he earned his doctoral degree.  He  continued to participate in research;  in the Orthopedics department, he was involved in a study of Ground Foot Reaction Forces.  If able to predict these forces accurately, physicians would be better able to customize orthotics for their patients.
