Sarah M. Allard

Assistant Project Scientist

Sarah received her PhD in Plant Science from the University of Maryland in 2014 and remained at UMD for a postdoctoral fellowship in the Maryland Institute of Applied Environmental Health. Throughout her career, she has maintained a focus on microbial ecology, food safety, and environmental sustainability. After receiving her B.A. in Biology from Haverford College in 2009, she began an ORISE fellowship in the Division of Microbiology at the FDA’s Center for Food Safety and Applied Nutrition. At FDA, she conducted environmental sampling for foodborne pathogen Salmonella enterica and evaluated a food safety biological control agent. As a graduate student at the University of Maryland, her dissertation work explored the influence of farming practices and environmental conditions on plant microbiomes in the complex agricultural environment. As part of the CONSERVE team based in the University of Maryland School of Public Health, she worked as a postdoctoral fellow and Assistant Program Manager. There, she developed a deep interest in water reuse for agriculture, and her research primarily focused on characterizing the microbiomes of nontraditional irrigation water sources including surface water and reclaimed wastewater. Sarah actively participated in farmer and community outreach, coordinated a multi-institution 2-year sampling effort, directed the CONSERVE Summer Intern Program, and led an educational trip to the Middle East. In her current role, Sarah is interested in exploring how microbiome research can be harnessed to support environmental sustainability and safe, productive food systems. She is also committed to helping students pursuing microbiome research prepare a diverse skillset to enable effective interdisciplinary research and communication. More information can be found on her website, and her publications can be seen here.

Jarrad Marcell-Hampton

Research Coordinator, UIC Ph.D. Candidate

Jarrad is currently working in tandem with the University of Illinois at Chicago and Argonne National Lab to cultivate a comprehensive understanding of the methodology required to employ the use of micro biome data and samples to the forensic world. In understanding touch DNA and the various manners in which our microbiota interact with the environment surrounding us, the scientific community will be able to utilize such specific data to profile likely suspects and to match biological signatures once a suspect has been apprehended. Moreover, he continues to work on his PhD while coordinating various research projects throughout the labs. His publications can be seen in here.


Sophia Carry

Ph.D. Candidate

Sophia graduated summa cum laude from CUNY Lehman College with a B.A. in Biology in 2015. There she investigated the effects of early environmental stressors on adult decision making in a lab colony of prairie voles (Microtus ochrogaster) with Dr. Maryam Bamshad for her honors thesis at Lehman College. Currently, she is a second year doctoral student in the Committee on Evolutionary Biology studying wildlife-microbe interactions in three populations of house sparrows (Passer domesticus). Her primary focus lies in discovering how differences in microbial communities due to environmental variations impact changes in the endocrine system, morphology, and behavior of house sparrows. Her end goal is to understand how microbes can influence fitness and shape the evolution of wildlife animals that are adapting to an increasingly urban world. Her publications can be found here.
