معرفی
Deb Bell-Pedersen is a University Distinguished Professor in the Department of Biological Sciences at Texas A&M University. She joined the department in 1997 and leads the Bell-Pedersen Lab, focusing on circadian rhythms and their molecular mechanisms in Neurospora crassa. Her research integrates molecular, biochemical, and genomic approaches to understand how circadian clocks regulate rhythmic gene expression and protein production, with implications for human health and aging.
Education: BS (Biology, SUNY Albany, 1983), MS (Molecular Biology, SUNY Albany, 1987), PhD (Molecular Biology, SUNY Albany, 1991), Postdoctoral Research at Dartmouth Medical School (Biochemistry).
Research Interests: The lab investigates circadian control of mRNA translation, ribosome function, and translation fidelity. Key discoveries include clock-driven regulation of eIF2α and eEF2 activity, rhythmic ribosome composition, and the link between circadian rhythms and aging. These findings suggest potential therapeutic avenues to enhance translation fidelity and combat age-related decline.
Publications: Recent work highlights circadian regulation of translation initiation factors, ribosome interactions, and mRNA localization via cytoplasmic granules. Themes include clock-driven post-transcriptional control, translation fidelity, and metabolic rhythms. The lab also explores circadian links to cancer and drug metabolism.
Awards: Recognized as a University Distinguished Professor, reflecting her contributions to chronobiology and molecular biology.
Grants & Advising: Ongoing research is supported by grants focusing on circadian mechanisms. Students advised have contributed to studies on tRNA synthetases, eIF2α phosphorylation, and glycogen metabolism. The lab collaborates with interdisciplinary teams in genomics, structural biology, and clinical applications.
Labs/Teams: The Bell-Pedersen Lab is part of the Center for Biological Clocks Research, emphasizing collaborative, multi-omics approaches to circadian biology.
