Now that you know what quantiFlash® does, these are the visionaries behind it:


Jim Wood - Wake Forest University

Jim is the visionary behind the LED pulser. He had the initial idea and made it a vision to all users of flow cytometry.

Jim received MS and PhD degrees in Biophysics from Pennsylvania State University. After completing a postgraduate position in the lab of Dr. Leon Wheeless at the University of Rochester Medical Center, where he contributed to the development of a 3D slit-scan flow cytometer, Jim moved to Florida, accepting a position with the EPICS Division of Coulter Corporation. He was the manager of the New Products Research and Applications Laboratory during most of his tenure at Coulter and Beckman-Coulter.  He consults for flow cytometry and pharmaceutical companies, and manages the flow cytometry shared resource at Wake Forest University School of Medicine Comprehensive Cancer Center (WFUCCC).

Toralf Kaiser - DRFZ

Toralf brings the passion and technical skills that made him one of quantiFlash’s primary lead user.

Toralf studied applied physics and biomedical engineering in Jena and Berlin, Germany. After finishing his studies, he worked as a cell sorter operator at the Max Planck Institute for Infection Biology. Since 2000, he has been Technical Head of the Flow Cytometry Core Facility (FCCF) at the DRFZ (Prof. Dr. Andreas Radbruch) , in Germany. He is a member of the International Society for Advancement of Cytometry (ISAC) and the German Society for Cytometry (DGfZ) and co-organizer of the EMBO courses Advanced Cytometry and Cell Sorting for 2003, 2008, and 2013. He is the co-developer of various cytometry-related technical innovations, including the disinfection UV-C module, SAW- sample agitator, and sidestream stabilization device.


Steve Perfetto - NIH

Steve brings the passion and technical skills that made him one of quantiFlash’s primary lead user.

Stephen received a B.S. degree in Medical Technology from the West Virginia University in 1977 and completed his M.S. degree in 1981 from West Virginia University. He studied and worked in the clinical Blood Bank and clinical immunology laboratories until 1988, when he joined the EPICS Division of Coulter Corporation. In 1990, he was recruited to the Walter Reed Army Institute of Research and was the manager of the core flow facility. While at WRAIR, he was involved in large HIV vaccine trials and developed functional to study the immune system of infected individuals. In 2000 he joined the NIH in the department of the Vaccine Research Center (VRC) as a staff scientist and manager of the flow core facility. This facility is the world-leader in multicolor flow cytometry and continues to actively develop this technology on a number of different fronts; one focus is on hardware development and reagent and analysis development.
