About the Scientist

Speicher is a recognized leader in the field of proteomics, the systematic study of the full set of proteins produced by a given cell, tissue, or organism.

Speicher joined Wistar in 1986 from the Yale University School of Medicine. He was born and raised in Pennsylvania and attended Pennsylvania State University as both an undergraduate and graduate biochemistry student.  He received his Ph.D. in 1977 and subsequently pursued postdoctoral training at the Yale University School of Medicine.  He then accepted a position on the Yale Medical School research faculty with a joint appointment as the Director of Yale’s Protein Chemistry Laboratory, prior to moving to Wistar.
