Cristina Lanzas was previously a research associate at the Department of Population Medicine and Diagnostic Sciences, Cornell University. She received her degree in Veterinary Medicine from Universitat Autònoma de Barcelona, Spain, in 2000, and her M.Sc. and Ph.D. in Animal Sciences from Cornell University in 2003 and 2007, respectively. Her research interests include the development and application of mathematical and epidemiological approaches to study dynamics and control of infectious diseases caused by zoonotic and enteric pathogens in both animal and human populations. Her research aims to understand the sources of variation that drive transmission dynamics and persistence of pathogens in host populations and to quantify the effect of control strategies. Her current research projects include modeling (1) the transmission and control of multi-drug resistant Salmonella, (2) the transmission dynamics of Clostridium difficile in human health-care settings, (3) the dissemination of antimicrobial resistance among enteric commensal bacteria in food animals. In addition to epidemiological modeling, her research has involved the development of mathematical models to address nutrient supply and excretion at the animal level.
