About Paul K. Wallace


Served from 2003-2021 as Director of the Flow and Image Cytometry Department at Roswell Park Comprehensive Cancer Center in Buffalo, NY. Currently a Professor Emeritus at Roswell Park and the Chief Scientific Officer at SciGro, Inc. SciGro is a partnership supporting the translation of research and preclinical stage technology into products for the biomedical industries. Past President of the International Society for Advancement of Cytometry an organization with over 2,000 members, active in the International Clinical Cytometry Society, Associate Editor of Clinical Cytometry, and the 2018 recipient of ICCS’s Wallace H. Coulter award for lifetime achievement in clinical cytometry.

Before joining Roswell Park, Dr. Wallace was an Assistant Professor of Immunology at Dartmouth Medical School, Hanover NH (1993-2003), a cofounder of Zynaxis Cell Science, Inc., Malvern PA (1988-1991), and the Supervisor of Flow Cytometry at SmithKline (now Quest) Clinical Laboratories King of Prussia, PA (SKCL; 1979-1988).
