David Novo PhD, Founder
David received his PhD in Biophysics from UCLA. His research concentrated on developing novel optical and mathematical techniques for measurements and analysis of localized fluorescent Calcium transients from a microdomain within a muscle cell. David also built several confocal microscopes, as well as writing the data acquisition and data analysis systems. Prior to commencing his PhD, David worked with Dr. Howard Shapiro, one of the leaders in the field of flow cytometry, performing research on membrane potential determination in bacteria using flow cytometry. During the course of this research they built several flow cytometers custom made for bacterial measurements. Two papers were published on the subject. David still maintains close ties to the flow cytometry community through his appointment to the Data Standards Committee of the International Society of Analytical Cytometry. This committee maintains the flow cytometry data file standard and deals with issues standardizing all sorts of flow cytometry related data storage and analysis issues. David frequently consults on data analysis issues related to flow cytometry and collaborates on many projects involving novel data analysis requirements.
