Education

  • Postdoctoral, 1992, The Jackson Laboratory
  • Ph.D., 1989, The University of Georgia, Athens
  • M.S., 1986, North Carolina State University, Raleigh
  • B.S., 1981, North Carolina State University, Raleigh

Research Interests

  • • Dr. Gaskins joined the faculty at the University of Illinois at Urbana-Champaign in 1992 and is Full Professor with appointments in the Departments of Animal Sciences, Biomedical and Translational Sciences and Pathobiology, the Division of Nutritional Sciences, the Carl R. Woese Institute for Genomic Biology and the Cancer Center at Illinois. He completed his dissertation research in cell biology at The University of Georgia in 1989. From 1989-92, he conducted postdoctoral studies in immunology at The Jackson Laboratory in Bar Harbor, Maine. Research in his laboratory focuses on host immunological-intestinal microbe interactions relevant to colorectal cancer with a particular interest in microbial sulfur and hydrogen metabolism. Efforts to understand colonic mucosal responses to hydrogen sulfide led to further interest in redox regulation of tumorigenesis resulting in a long-time collaboration with bioengineering faculty at Illinois to create genetically-encoded biosensors and engineered platforms for the study of redox poise in subcellular compartments in live cells. Dr. Gaskins serves as Associate Director for Education for the Cancer Center at Illinois and Deputy Director of the NIH-supported Tissue Microenvironment Training Program.
