Jon Hibshman

Jon Hibshman is an Assistant Professor in the Department of Biological Sciences at Southern Methodist University (SMU), where he leads the Hibshman Lab. His research focuses on understanding how cells and organisms survive extreme stress, particularly desiccation (complete drying). He employs interdisciplinary approaches combining genetics, cell biology, molecular biology, and biochemistry to investigate stress tolerance mechanisms.

Dr. Hibshman's educational background includes:

• B.S. in Biochemistry and Molecular Biology from Gettysburg College
• Ph.D. in Genetics and Genomics from Duke University
• Postdoctoral training at the University of North Carolina, Chapel Hill

His research centers on extreme stress tolerance, particularly desiccation. The lab uses tardigrades and C. elegans as model organisms to understand the molecular mechanisms that allow certain organisms to survive near-complete dehydration. These studies have implications for aging, rejuvenation, and biomedical applications such as the storage of sensitive biological materials including cells, tissues, organs, proteins, and vaccines. The lab's work spans multiple disciplines, examining DNA repair pathways, protein aggregation prevention, and cellular protection mechanisms under extreme conditions.

Dr. Hibshman's publications reveal a strong focus on desiccation tolerance mechanisms across multiple organisms. His work examines tardigrade biology, DNA repair pathways under stress conditions, small heat shock proteins, and the molecular basis of anhydrobiosis. The research spans fundamental biological questions about extreme stress tolerance while maintaining a translational perspective toward biomedical applications.

His scientific contributions include:

• Discoveries about tardigrade small heat shock proteins that limit desiccation-induced protein aggregation
• Identification of LEA motifs that promote desiccation tolerance
• Studies on DNA repair pathway upregulation in response to extreme stress
• Development of protocols for studying stress responses in model organisms

Dr. Hibshman's lab employs a highly interdisciplinary approach, using genetic, cell biological, molecular, and biochemical methods to uncover fundamental principles of cell stress resistance with implications for aging and biomedical applications.
