Rate My Professor Gessica Barros

Gessica Barros serves as a Postdoctoral Associate in the Department of Biology at Duke University. She earned her bachelor’s degree in Biochemistry and her master’s degree in Agricultural Microbiology from the Federal University of Viçosa. Barros completed her PhD in Biological Chemistry at the Federal University of Rio de Janeiro, with research focused on translation quality control. Her current work centers on the role of ribosome ubiquitination in translation control under oxidative stress conditions. Barros has contributed to publications including the 2023 paper titled “The ubiquitin conjugase Rad6 mediates ribosome pausing during oxidative stress” in Cell Reports and the review “The central role of translation elongation in response to stress” in Biochemical Society Transactions. She holds a research grant from the National Institute of General Medical Sciences titled “Dissecting the roles of ubiquitin in translation control,” awarded from 2020 to 2030. Barros received the Outstanding Postdoc Award at Duke University. Her academic interests include gene regulation, translation control, and molecular biology, as reflected in her verified Google Scholar profile and laboratory affiliation in the Silva Lab.

Throughout her career, Barros has maintained a focus on fundamental mechanisms of protein synthesis and cellular responses to stress. Her training across Brazilian institutions provided a strong foundation in biochemistry and microbiology before transitioning to postdoctoral research at Duke. Barros participates in ongoing projects examining ubiquitin-mediated processes in translation during oxidative stress, utilizing techniques such as Ribo-seq and Disome-seq in model organisms like Saccharomyces cerevisiae. Her contributions appear in peer-reviewed journals and support broader investigations into gene expression regulation. No additional appointments, major awards beyond the noted postdoc honor, editorial roles, or public lectures are documented on official university profiles or academic databases. Barros remains actively engaged in research within the Biology department at Duke University.
