Postdoctoral Training

Postdoctoral Fellowship, Department of Biochemistry, University of Tennessee, Memphis, TN



After completion of her postdoctoral training in 2005, Dr. Sabek received dual appointments as an Assistant Professor in the College of Nursing and Department of Surgery at the University of Tennessee in Memphis, Tennessee. She has collaborated on several NIH-funded research grants and published over 30 peer-reviewed papers. Dr. Sabek joined The Methodist Hospital Research Institute in 2007.

Description of Research

Dr. Sabek´s research focuses on islet cell transplantation, and specifically, the surrogate markers for prediction of long-term transplantation outcomes. She also aims to improve transplantation outcomes through the development and validation of improved techniques for islet recovery, isolation, engraftment, and post-transplant functioning/preservation. Dr. Sabek also conducts studies investigating potential biomarkers of allograft rejection.

Major Areas of Research

Islet cell transplantation, Functional Genomics, allograft rejection
