Jeremiah Winter, Ph.D.

Director of Biochemistry and Molecular Biology | Professor of Biology

Center for Natural Sciences, Room 244
(434) 592-7708


  • Ph.D., Integrative Biosciences (Molecular Medicine Option) from Penn State College of Medicine
  • B.S., Biology from Cornerstone University


Dr. Jeremiah N. Winter serves in the Biology & Chemistry department as a Professor of Biology. He specializes in Cell Biology and Molecular Biology and is especially interested in eukaryotic cell pathways that are involved in insulin signaling, particularly those that lead to insulin resistance and their relationship to the mTORC1 pathway.

Dr. Winter has publications in the American Journal of Physiology-Cell Physiology and has worked with numerous students on a variety of research projects. He has been blessed to train students at each academic level, from undergraduates to Ph.D. students. He was led to Liberty to continue teaching the sciences from the ultimate foundation of the never-changing truths of God’s holy, inspired, and inerrant word, to further his research to the benefit of the students and community at Liberty, and to glorify and enjoy God through each moment in the classroom.
