Lori Roberts, PhD
My team of biologists works closely with Biotium chemists to turn our novel fluorescent reagents into valuable biological assays. We also provide our users with in-depth technical advice and support. Before joining Biotium in 2010, I performed research at Genentech and XenoPort, where I applied a variety of fluorescence imaging approaches to cellular, developmental, and physiological questions. I earned my PhD in Biomedical Sciences from UCSF, and my BA in Biology from Reed College.
Patrick McGarraugh, PhD
As Director of Manufacturing I oversee all ISO9001:2015 certified production and quality control practices at Biotium. I am devoted to ensuring our products meet the best quality standards that guarantee our customers receive a consistent and conforming product every time they place an order. While directing our manufacturing department takes up a lot of my work, I still find time to dig deep into the organic chemistry literature, and help develop novel fluorescent dyes with the rest of our R&D team. Prior to my work at Biotium, I earned my PhD in organic chemistry at the City University of New York.
Director, Business Operations
As the Directory of Business Operations I am responsible for overseeing the customer support staff and ensuring the business runs efficiently day in and day out. This includes managing our manufacturing, distribution, and service processes as well as assisting with our ISO9001:2015 annual audits and certifications. I’m highly motivated by seeing the results of my efforts translate into increased productivity and sales. That’s why I’m driven to be hands-on every step of the way with the inner workings of Biotium. Our future is very bright!
