I have 25 years of experience and specialization in optics, with specific knowledge in flow cytometry, cell sorting, and hematology analysis. My declarations and testimony have won my clients cases in cell sorting (IPRs, PGRs). I have been issued 19 patents in optics, lasers, microfluidics, and biophotonics (17 more pending), as well as professional awards. I am Senior Member of both OSA and SPIE. I founded and run a design, consulting, and product development firm, and I cofounded a design automation software company, both in Silicon Valley. I have published on subjects from flow cytometry to optical design, and I teach courses on these subjects.
