He is jointly appointed between the Animal science department and the Emerging Pathogens Institute, providing an excellent working environment to lead this integrated project.

J. Glenn Morris, Jr., M.D., Professor, Project Consultant, Infectious Disease Epidemiologist

Dr. Glenn Morris assumed the position of Director of the Emerging Pathogen Institute at the University of Florida in August 2007. He was recruited from the University of Maryland, Baltimore, where he was a professor and chairman of the Department of Epidemiology and Preventive medicine in their School of Medicine, as well as an interim dean of their School of Public Health. In addition to his position as EPI Director, Dr. Morris is a professor of infectious diseases in the UF College of Medicine. Current research initiatives at EPI include work with vector-borne diseases (malaria, West Nile, equine encephalitis, blue-tongue (a major animal pathogen), and citrus greening, tuberculosis, multi-antibiotic resistant bacteria (such as methicillin-resistant staphylococcus aureus or MRSA), and food safety and diarrheal infections (including cholera and E. coli O157:H7). Studies range from very basic work on evolutionary genetics through use of real-world data and bioinformatics to develop predictive mathematical models for disease transmission within populations. Morris received his B.A. from Rice University in Houston in 1973, and his M.D. degree and a master’s degree in public health and tropical medicine from Tulane University, New Orleans, in 1977. He is board certified in both internal medicine and infectious diseases.

Judy Johnson, Ph.D., Professor, Co-PD, Clinical Microbiologist

Dr. Judy Johnson researches microbial pathogenesis, antibiotic resistance, and pathways of transmission of bacterial species and genes within and between clinical, community and agricultural settings. She specializes in the bacterial genera Vibrio and Staphyloccocus. Dr. Johnson is also the director of core laboratory services in the University of Florida’s Emerging Pathogens Institute, acting as a conduit between researchers in the human health sciences and the Emerging Pathogens Institute. In a broad sense, Dr. Johnson’s work investigates the causes of bacterial pathogenicity, and she specializes in researching the many different expressions and compositions of the polysaccharide surfaces that coat bacteria. She examines how the surface coating is constructed, how different constructions alter a bacterium’s environmental interactions, and how the structures evolve. She is also interested in what toxins are present and how toxins are transferred both between individual bacteria (horizontal gene transfer) and between bacterial species.

Mauricio Elzo, Ph.D., Professor, Co-PD, Animal Geneticist 

Dr. Elzo  leads a national and international research program on genetic improvement of unibreed and multibreed populations of beef cattle, dairy cattle, buffalo, and swine for traits of economic importance (fertility, growth, feed efficiency, carcass, and meat quality).  His research covers theoretical, computational, and applied genetic and genomic areas using experimental, field, and survey data from the United States and cooperating countries (Bolivia, Brazil, Chile, Colombia, Ethiopia, Mexico, Thailand).

Volker Mai, Ph.D., Co-PD, Associate Professor, Molecular Epidemiologist

Dr. Mai and his lab at the University of Florida Emerging Pathogens Institute investigate the complexity and dynamics of naturally occurring microbial communities inhabiting the digestive tracks of humans. Individuals typically have their own unique composition of intestinal microbiota, but Mai’s studies seek to determine predictable patterns of species complexity and dynamics that can evaluate an individual’s susceptibility to disease. He and his lab analyze gut microbiota for associations between its composition, the host’s diet, and the host’s state of health or disease. Dr. Mai’s lab also examines whether or not an individual’s intestinal microbiota composition affects their susceptibility to intestinal pathogens (particularly those causing diarrheal diseases), and if manipulation of this microbiota can help to prevent disease frequency or severity.

Soohyoun Ahn, Ph.D., Assistant Professor, Co-PD, Food Scientist

Dr. Soohyoun Ahn is an Assistant Professor at the University of Florida. Her research interests involve the development of rapid and sensitive detection assay for pathogens and biological toxins in foods is critical for food safety, bio-security and clinical diagnosis. Dr. Ahn’s research interest is to develop rapid, inexpensive and simple assays for simultaneous detection of multiple pathogens in foods or in the environment. For the development of these assays, she utilizes various techniques, including immunomagnetic separation, ELISA, multiplex PCR, lateral flow assays, bead-based sensors and microarray. She is particularly interested in building a small, portable microfluidic platform, which will be ideal for field assays. Current research projects include: (1) development of bead-based suspension microarrays for simultaneous detection and characterization of multiple foodborne pathogens, (2) development of immunofluorescence assay for simultaneous detection of Salmonella and E. coli O157:H7, and (3) Study of STEC prevalence in small-sized cattle farms.
