Jessica A. Scoffield is an American microbiologist and an Assistant Professor in the Department of Microbiology at the University of Alabama at Birmingham School of Medicine. Scoffield studies the mechanisms by which oral commensal bacteria interfere with pathogenic bacterial growth in order to inform the development of active therapeutic tools to prevent drug resistant pathogen infection. In 2019, Scoffield became the Inaugural Recipient of the American Association for Dental Research Procter and Gamble Underrepresented Faculty Research Fellowship.

Early life and education

Scoffield grew up in Chattanooga, Tennessee.[1] She pursued her undergraduate degree at Tuskegee University in 1998, which is when she discovered her passion for biomedical research.[1] Scoffield graduated with a Bachelors of Science in Biological Sciences in 2002.[2] Following her undergraduate degree, Scoffield stayed at Tuskegee University to complete her Masters of Science in Biology.[2] While at Tuskegee, Scoffield helped to design plant growth systems for space missions and then helped develop edible vaccines using plants.[3] She explored the use of Agrobacterium-mediated gene transfer efficiency in sweet potato cultivars, in an effort to improve sweet potato production in Alabama.[4] She presented this emerging technology at the In Vitro Cellular and Developmental Biology Symposium.[5] She completed her Master’s training in 2004.[2]

Following her masters, Scoffield pursued her graduate training at Auburn University in Auburn, Alabama.[2] She trained under Laura Silo-Suh in the Department of Biological Sciences and she explored the mechanisms by which Pseudomonas aeruginosa growth mechanisms and virulence factor production.[6] P. aeruginosa infections are one of the leading causes of chronic pulmonary infections in cystic fibrosis patients, often resulting in mortality.[7] Her work helped to explore which environmental factors and adaptations lead to persistent and severe infection in CF patients.[6] Probing the metabolic glyoxylate pathways of P. aeruginosa, Scoffield found that isocitrate lyase, an important enzyme in the glyoxylate pathway, facilitated adaptation of P. aeruginosa to the CF lung.[7] They also found that the glyoxylate pathway becomes up-regulated in specific bacterial isolates from CF patient lungs.[6] Based on this finding, Scoffield explored the genetic mechanisms of pathway up-regulation and she showed that GlpR, a transcriptional repressor for glycerol metabolism, also regulates the glyoxylate pathway, shedding light on the interactions between fatty acid and glycerol metabolism in PO. aeruginosa.[6] Scoffield completed her PhD in microbiology in 2012.[2]

Career and research

After completing her PhD training, Scoffield pursued her postdoctoral training at the University of Alabama at Birmingham.[2] She trained under the mentorship of Hui Wu in the Department of Pediatric Dentistry.[8] Scoffield continued to study P. aeruginosa, but focused on its infection of the oral cavity.[8] She explored how commensal bacteria in the mouth help to suppress P. aeruginosa infection.[8] She found that commensal bacteria in the oral cavity suppress the growth and infection of pathogenic P. aeruginosa through their release of nitrate and H202.[8] This work suggests that H202 and nitrate may present an infection treatment strategy in patients with P. aeruginosa infections.[8] Scoffield then found that P. aeruginosa require nitrite reductase to survive in the presence of nitrite producing commensal oral bacteria.[9]

In 2018, Scoffield was appointed to Assistant Professor at the University of Alabama at Birmingham in the Department of Microbiology.[2] She also holds secondary appointments in the Department of Medicine Division of Pulmonary, Allergy, and Critical Care, as well as an appointment in the Department of Pediatric Dentistry. Scoffield also works in the Cystic Fibrosis Research Center.[2] Scoffield is a member of the American Society for Microbiology as well as the American Association for Dental Research (AADR).[10] In 2019, she became the inaugural recipient of the AADR Procter and Gamble Under-represented Faculty Research Fellowship.[11]

Scoffield is also the principal investigator of the Scoffield Lab. Her lab explores the role of commensal bacteria in maintaining homeostasis.[12] The lab focuses on both oral and pulmonary commensal bacteria and how these bacteria are able to control and suppress pathogenic bacteria in these niches.[12] The main pathogenic bacteria the Scoffield Lab explores are Streptococcus mutans, the major cause of pathogenic oral infection, and P. aeruginosa, the major cause of pulmonary infection in CF patients.[12] In 2019, Scoffield and her team explored how P. aeruginosa infection of microglia impacts extracellular vesicle (EV) biogenesis and composition. The team found that P. aeruginosa infection and treatment of microglia with P. aeruginosa EVs altered protein and mRNA expression in microglia derived EVs and led to decreased cell viability. These findings suggest that EVs alone could be used as a biomarker of infection and guide the development of tools to target resistant bacteria.[13]
