The people who lead Berkeley Nucleonics, and the founders whose work still shapes how we build.
A second-generation team with deep roots in the products we make.

David Brown has led Berkeley Nucleonics as president since 2001, seven years after joining the company. Under his direction the company broadened its reach across test and measurement and radiation detection. He guided R&D on the Model 935 SAM isotope identifier, the SAM Defender LaBr radionuclide identifier, and the PB-5 NIM pulse generator, and helped shape training programs for the U.S. Air Force. He holds a B.A. in entrepreneurial management from San Francisco State University. A second-generation operator, he lives in San Rafael with his family.

John Reynolds joined in 2008, starting in marketing before stepping into operations leadership. He oversees purchasing, account management, and logistics, and his sales and marketing background has made the operation measurably more efficient. He holds a B.S. in business marketing from Sonoma State University.

John Lauder joined in 2008 as an applications engineer and rose to chief technical officer for the test and measurement and RF/microwave lines. He has anchored key customer relationships and provided technical leadership for many years. Away from the bench he is a dedicated cyclist.

Mark Slattery joined the applications team in 2008 and now leads the department. He brings more than 30 years of engineering experience across motion control, nuclear detection, and test and measurement. Customers know him for clear technical communication and responsive service.
We remember two colleagues whose decades of work built the foundation the company stands on.

John Yee began in the early 1970s as a bench engineer and advanced into application management over a 45-year career. He helped shape the company's arbitrary waveform generator and light pulser lines and taught its products to a generation of customers. He earned electrical engineering degrees from Stanford and UC Berkeley, and was a finalist for the state's Older Worker Award in 2002.

Mel Brown founded Berkeley Nucleonics in 1963 after seven years at Lawrence Berkeley National Laboratory. He pioneered the company's precision pulse generators, its digital delay generators in the 1970s, and its solid-state laser instruments in the 1980s. He held B.S. and M.S. degrees in electrical engineering from UC Berkeley. The approach he set still guides the company today.
