During one deployment, Lyon participated in 31 mass casualty events and 53 emergent walking blood drives, and assisted with a variety of life-saving surgical procedures. She was featured, along with several of her SOST team members, by CBS News in 2018 for their heroic efforts. 

Lyon is a member of the Special Operations Medical Association (SOMA), and was recently elected to serve as an SOMA board member. This role has given her a platform that reaches military and civilian counterparts throughout the U.S. and the world.

As a public health physician, Pavlin has served as a mentor in applied epidemiology both in the field and in a classroom setting. She has published her public health research extensively, and has served in variety leadership roles throughout her career. 

While in the Army, Pavlin was the assistant chief of Operational Medicine at the U.S. Army Medical Research Institute of Infectious Diseases from 1995 until 1998. As such, she developed new training methods, including satellite broadcasts, to train medical personnel to recognize, prevent, and treat disease agents that could be used in biological terrorism or warfare.

Pavlin then became chief of the Department of Field Studies at the Walter Reed Army Institute of Research until 2005. After receiving her PhD from USU, she moved to Bangkok, Thailand, where she was chief of Global Emerging Infections at the Armed Forces Research Institute of Medical Sciences and worked with the DoD’s Global Emerging Infections Surveillance and Response System. 

She returned to USU in 2010 to serve as the director of the Division of Epidemiology and Biostatistics in the Department of Preventive Medicine and Biostatistics.

Christina S. Faherty, PhD, Graduate Education Class of 2009

Dr. Christina S. Faherty is a Molecular Biologist in Pediatrics at the Mucosal Immunology and Biology Research Center at Massachusetts General Hospital and Assistant Professor of Pediatrics at the Harvard Medical School. Faherty is a well-established researcher in bacterial pathogenesis with a focus on enteric pathogens, vaccine development, and host-pathogen interactions.

Faherty earned her PhD in Emerging Infectious Diseases from USU in 2009. Since then, she has been particularly interested in understanding Shigella, a pathogen that causes a significant global health burden each year by causing millions of infections predominantly in children under age five in developing countries. By researching pathogenesis from the perspective of the bacteria, in which they ultimately survive and spread, Faherty’s goal is to develop better treatments and fight these infectious diseases. In 2017, Faherty and a team of scientists discovered how Shigella survives bile salts in the gastrointestinal tract, and in 2019, discovered Shigella adherence factors required for attachment to host cells. These discoveries could eventually lead to new therapeutic targets or new methods for vaccine development for Shigella.

Faherty’s work has been funded by the National Institute of Allergy and Infectious Diseases, and the Bill and Melinda Gates Foundation. She has published extensively in scientific journals, including the cover article of the American Society of Microbiology’s mSphere, with much of it featured in mainstream media outlets. 

While Faherty’s area of expertise is centered on investigation, she has contributed significantly to teaching, mentoring and advising students, residents, and fellows in the classroom and laboratory settings. In teaching, she encourages students to “think like a scientist.” Faherty says by showing students how to apply the knowledge they learn in the classroom to the problem-solving skills required for research, students learn various techniques and develop the skills necessary to successfully complete a thesis and to continue a career in research. 

Faherty is an active ad hoc reviewer for a number of funding agencies and journals, including PLoS One; PloS Pathogens, Infection and Immunity; Gut Microbes; Genes; Frontiers in Cellular and Infection Microbiology, Frontiers in Microbiology, Journal of Visualized Experiments; Journal of Medical Microbiology; AJP Gastrointestinal and Liver Physiology; Tropical Disease, Travel Medicine and Vaccines; Microbial Drug Resistance, Pathogens and Disease, Scientific Reports, and mSphere. She is a review editor for Frontiers in Cellular and Infection Microbiology, and an editorial board member for Infection and Immunity. 

She has been an active member of the American Society for Microbiology since 2006.
