    Brittney attended the University of South Florida where she earned a B.S. in Microbiology and then a Ph.D. in Cell and Molecular Biology. Her Ph.D work was done in the laboratory of Dr. Les Shaw where she studied the transcriptional regulation of Staphylococcus aureus secreted proteases, as well as how these secreted proteases regulate disease progression via their modulation of virulence factor stability. In Spring 2020, Brittney joined the Cassat lab as a postdoctoral research fellow where she is working to understand the mechanisms S. aureus uses to withstand antibiotic treatment in an osteomyelitis infection. Outside of the lab, Brittney enjoys hiking and biking.

  • Kara is from Whitehall, PA and earned a B.S. in Biology from Susquehanna University. She received her Ph.D. in Microbiology and Immunology working in the laboratory of Dr. William Goldman at the University of North Carolina at Chapel Hill, where she studied Yersinia pestis interactions with host cells during primary pneumonic plague. Kara joined the Cassat lab in 2020 as a postdoctoral research fellow in the Division of Pediatric Infectious Disease. Her project seeks to understand the consequences of co-infection on osteomyelitis disease progression. In her free time, Kara enjoys running, reading, and watching UNC basketball (go Heels!!). 

  • Caroline Minton

    Research Assistant
    Division of Pediatric Infectious Diseases

    Caroline graduated from Harding University in her home state of Arkansas with a B.S. in Biology. Following her undergraduate studies, she attended Emory University in Atlanta, GA, and received a Master of Public Health with a concentration in Global Health and Infectious Disease. Caroline now works full-time as a research assistant in the Cassat lab. In her free time, she likes to go running, embroider, and attend (socially-distanced) concerts.

     

  • Clara was born and raised in Toronto, Canada, and attended NYU for her undergraduate studies, where she double majored in Biochemistry and Classics. She began her research journey at The Rockefeller University working under Dr. Charles Rice, before moving to NYU Langone as a founding member of the Dittmann Laboratory. She joined the Vanderbilt MSTP in 2019. In the Cassat Lab, her research focuses on the role of RANKL signaling in regulating the antibacterial response in monocytes. In her free time, Clara loves working out, cooking for a crowd, and playing with her cat, Fig Blossom.

  • Juan P. Barraza

    Postdoctoral Fellow
    Department of Pathology, Microbiology, and Immunology

    Juan was born in Mexico City and earned his B.S. in Biochemistry from the University of Texas at Austin. He started his graduate work in Austin with Marvin Whiteley and moved with his lab to Georgia Tech, where he obtained his PhD. His work focused on the development of tools for characterizing the spatial structure of microbial communities within the context of infectious diseases. In 2022, Juan started his postdoctoral work in a joint venture with the Cassat and Skaar lab at the Vanderbilt Institute for Infection, Immunology and Inflammation. His project incorporates quantitative imaging, clinical samples and single cells assays to answer basic questions about host-pathogen interactions in the gut. He is an avid cyclist, live music enthusiast and is working towards developing a world-class taco experience from his kitchen.

    Laura is from Lexington, NC and received a B.A. in Biology from the University of North Carolina at Chapel Hill. As an undergraduate student, she studied SIR2 involvement in the recruitment of condensin to sites of tension in the chromatin in the Bloom lab. After graduation, she worked as a Research Technician II in the lab of Janelle Arthur at UNC-CH investigating how the yersiniabactin high-pathogenicity island of resident E. coli modulates the host response in the context of inflammatory bowel disease (IBD). Laura joined the Cassat lab to study osteoimmunology and host-pathogen interactions in S. aureus osteomyelitis. She has since pursued a career at Covance as a Study Start Up Associate.
