Jeff joined Droplet Measurement Technologies as President and CEO in 2017. But his enthusiasm for technology and strength for leadership go much farther back. Before coming to Droplet, Jeff served in executive roles and on the Board of Directors at Avo Photonics, Inc. and Ocean Optics, Inc. (both wholly-owned subsidiaries of Halma plc). Prior to Halma, Jeff held several senior leadership positions focused on commercializing new technologies and developing new business models at Hach-Lange (a wholly-owned subsidiary of Danaher Corporation). Working as President of Hach Homeland Security Technologies at one point, Jeff was responsible for some of the platforms’ most challenging work, including that for water/air security, distribution monitoring, advanced technologies, and engineering services.

Jeff received his Ph.D. with a focus in chemical and biochemical engineering at the University of South Florida. He also has a master’s degree in chemical engineering (with a focus in process controls), and he received his bachelor’s degree in chemical engineering from Virginia Tech.
