Dr. Berg has 45 years of experience in microbial molecular genetics, initially focused on E. coli, its bacteriophages, plasmids and transposable elements. He discovered the bacterial kanamycin resistance transposon Tn5 in 1975 and studied its mechanisms of insertion and excision and utility as a tool for molecular genetics for some 15 years. Since 1992 he has studied Helicobacter pylori, its epidemiology, genome evolution (including its transposable elements), and mechanisms of drug resistance, colonization and disease. A primary focus has been on the genetic diversity this gastric pathogen in relation to human health and disease in Amerindian and other people in Latin America -- much of it in collaboration with Profs Robert H. Gilman and students at Univ Peruana Cayetano Heredia in Lima, Peru, and Teresita Bertoli, Universidad Dr Jose Matias Delgado in San Salvador, El Salvador.

Prior to coming to UCSD, Dr. Berg was a member of the Washington University Medical School Faculty (Molecular Microbiology, Genetics, Medicine) for 35 years, taught in courses on microbial molecular genetics and infectious disease, and advised or guided the research of many students during this time, including a dozen from Latin America.
