Meet Our Team

Raja S. Tannous (rtannous@berkeleyanalytical.com)
Co-Founder & Laboratory Director

Since co-founding Berkeley Analytical in 1989, Raja has overseen daily operations in the laboratory, as well as technical, financial, and strategic management—and expansion.

With a background in biochemistry, Raja’s research interests include synthesis and purification of organic chemicals, measuring emissions and inhalation exposures from biomedical devices, and chemical testing of all types of building and consumer products—e.g., textiles, composite woods, insulation, paint, cleaning products, and cosmetics. He is an active participant on numerous product materials and emissions working groups and is a member of the USGBC LEED Indoor Environmental Quality Technical Advisory Group.

Prior to founding BkA, Raja worked as an analytical and synthetic chemist in the Chemical Engineering Department at the University of California, Berkeley (UCB) and in the organometallic chemistry group at Lawrence Berkeley National Laboratory (LBNL). It was at LBNL where Raja met Al Hodgson.

Raja holds a degree in biochemistry from UCB, and has made the San Francisco Bay Area his home for over 30 years.

Alfred T. Hodgson (ahodgson@berkeleyanalytical.com)
Co-Founder, Research Director & Quality Manager

Al Hodgson co-manages day-to-day operations and planning with Raja, while also directing test method development, implementation, and validation within the laboratory and leading its participation in consensus standard activities.

Al founded BkA with Raja in 1989.  In 2007, he retired from Lawrence Berkeley National Laboratory (LBNL) where he was a staff scientist in the Indoor Environment Department, one of the first academic indoor air quality research groups. During his tenure at LBNL, Al was a group leader and principal investigator on projects for the U.S. Department of Energy, CA Air Resources Board, CA Office of Environmental Health Hazard Assessment, and others. His projects included evaluation of UVPCO (ultra-violet photocatalytic oxidation) air cleaners, ozone initiated air chemistry of cleaning products, children’s exposure to traffic-related emissions, and VOC source reduction techniques for homes and schools. Al is the past chairman of ASTM Subcommittee D22.05 on Indoor Air.

Al has authored and co-authored numerous peer-reviewed publications related to VOC source characterization and dynamics in indoor environments. Al grew up in Central California and attended the University of California at Santa Barbara, earning a degree in Zoology. His CV can be downloaded here.
