I have been a member of the Department of Biological Sciences at California State University, Long Beach, since 1988. I am one of several faculty members in the Department contributing to the marine biology program. I will be retiring after the Spring 2015 semester.

Research Interests

My research  interests are in the area of marine algal physiology and biochemistry (see Selected Publications & Presentations). I am particularly interested in the physiology of kelps (Order Laminariales), algal halogen metabolism, and the biogeochemistry of halogens in the marine environment. My lab has been investigating the dynamics of algal halomethane production focusing on methyl iodide, methylene bromide and bromoform. We have been elucidating the physiological and environmental factors that influence this process using both phytoplankton and seaweeds.  Recently I have been interested in the uptake of  Fukushima released radionuclides by our canopy forming kelps Macrocystis and Nereocystis. This has lead to the  Kelp Watch 2014 - 2015 campaign.

Under the direction of Dr. David J. Chapman, now Professor Emeritus - UCSB,  I received my Ph.D. in Biology (1978)  from UCLA. He introduced me to the unique halogenated natural products of marine algae. It was in his lab that I became interested in algal halogen metabolism which resulted in my dissertation research on bromophenol biosynthesis in the red alga Odonthalia floccosa. I was a Research Fellow in the laboratory of  the late Dr. Wheeler J. North at Caltech's Kerckhoff Marine Laboratory in Corona del Mar, CA. My association with Dr. North resulted in a deep appreciation of the marine environment and fascination with the physiological ecology of kelps, especially the giant kelp Macrocystis. He introduced me to Dr. Minoo Dastoor, a research director at the Jet Propulsion Laboratory, who was extremely interested in the source of atmospheric halocarbons, especially the monohalomethanes (methyl halides). Thus began my research of marine algal production of halomethanes. Except for a brief foray into agar biosynthesis and production with a small company in Santa Cruz, CA, which no longer exists. For most of my career I have been investigating marine algal halomethane production. Recently, I have been involved in managing Kelp Watch 2014 - 2015 a collaborative project between myself and Dr. Kai Vetter.

Graduate Students                                                                                                                                                     

The Masters Degree is the terminal graduate degree at CSULB. The Department offers the Master of Science in Biology by thesis. Because of my retirement, I am no longer accepting Graduate Students. My past students have conducted high quality research and are listed below. My research at CSULB would not have been successful without their participation.
