Professor Emeritus, Animal Sciences

Areas of Research

3D Cell Culture, Animal Sciences, Brain Cancer, Colon/Colorectal Cancer, DNA, Genes/Genomics, Gut Microbiome, Mitochondria, Tumor Microenvironment

Research Program and Theme

  • Program: Cancer Engineering and Biological Systems
  • Theme: Mechanistic and Quantitative Biology

Research Focus

H. Rex Gaskins’ research focuses on host-intestinal microbe interactions relevant to colorectal cancer with a particular interest in microbial sulfur 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 engineer platforms to study redox poise in subcellular compartments in live cells.
