Dr. Bogosian heads a department at Monsanto Company conducting basic and applied research in agricultural biotechnology, primarily focused on enhancing the productivity of animal agriculture. This research also includes the design and construction of recombinant microorganisms that produce products of interest in fermentation-based processes.

Dr. Bogosian's main areas of expertise include the biochemistry, genetics, and physiology of microorganisms, particularly as applied to the production of useful products by fermentation. He is also an expert on infectious diseases in animal agriculture, including anthrax, hoof and mouth disease, bovine spongiform encephalopathy (BSE, or "mad cow disease") and related prion diseases such as chronic wasting disease (CWD) of deer in the Midwest and Creutzfeldt-Jakob disease (CJD) of humans, and of potential agents of bioterrorism such as smallpox, ricin, and botulinum toxin.

His is also interested in the perception of science and technology by the public and the media. He says "Scientists need to be able to explain complex technical issues in a clear and understandable manner.
