Early in his career, Steven held R&D positions for over 3 years at The British Textile Technology Group Plc, followed then by 6 years as a senior university lecturer in medical microbiology and later the positions of Chief Scientific Officer and Director of R and D at Aseptica, Inc., and senior clinical fellowships at the Centers for Disease Control,
Atlanta, and Leeds Teaching Hospitals Trust, Leeds, United Kingdom. More recently, Steven held senior R&D manager positions at Bristol Myers Squibb, ConvaTec, Advanced Medical Solutions PLC and also held an honorary Professorship of Microbiology at West Virginia University. In
2011, Steven joined ScapaHealthcare PLC as Vice President of Global Healthcare R&D and was awarded an honorary Professorship at The University of Liverpool, UK. He has written over 260 scientific publications and conference abstracts on water microbiology, biofilms, antimicrobials, and infection control and has authored or edited six textbooks on biofilms and microbiology and provided over 100 presentations on biofilms and public health worldwide.
Marylynn V. Yates is Professor of Environmental Microbiology and Distinguished Teaching Professor at the University of California, Riverside. She serves as Dean of the College of Natural and Agricultural Sciences, and is Chair of the University of California Global Health Institute’s Education Committee. Dr. Yates holds a B.S. in Nursing from the University of Wisconsin, Madison, an M.S. in Chemistry from the New Mexico Institute of Mining & Technology, and a Ph.D. in Microbiology from the University of Arizona. Her research interests include characterizing and predicting the fate and transport of human enteric pathogenic microorganisms in soils, water, and wastewater; development of methods for rapid, sensitive detection of infective enteric viruses in water samples; human pathogen considerations associated with wastewater reuse and biosolids application to land; and the use of indicators for predicting pathogen occurrence and behavior in the environment. Dr. Yates serves as an editor for Applied & Environmental Microbiology, as a member of the Water Science & Technology Board of the National Research Council, and on the USEPA’s Science Advisory Board Drinking Water Committee. She is a fellow of the American Association for the Advancement of Sciences, the American Academy of Microbiology, and a National Associate of the National Academies of Science.
Dr. Williams currently leads the Oral Microbiology Group based at the School of Dentistry, at Cardiff University, Cardiff, UK. Since Dr. Williams’ first degree (Cardiff University), he has worked in the pharmaceutical industry, food microbiology and as an academic researcher. Having completed a PhD at the School of Dentistry in Cardiff on the immunopathogenesis of oral candidosis, Dr. Williams’ research has continued within Cardiff University and primarily focuses within the field of Clinical Microbiology with an emphasis on studies involving microbial biofilms. Dr. Williams’ research encompasses investigating biofilm susceptibility to antimicrobial agents, expression of virulence factors such as hydrolytic enzyme production, adhesion, and microbial modulation of innate immune responses. Of particular interest has been research into the development of biomaterials (e.g. silicone rubber, acrylic, titanium) to inhibit biofilm formation on medical devices. Dr. Williams is a previous recipient of the Senior Colgate Award (British Society for Oral and Dental Research) and the International Hatton Award (The International Association for Dental Research).
Dr. Rachel Chalmers is the director of the Cryptosporidium Reference Unit, Public Health, Wales. Her research includes evaluation of new laboratory methods for Cryptosporidium detection, diagnosis, typing and subtyping, epidemiology and seroepidemiology, risk factors, and prevention.
