Sarver Heart Center Welcomes New Faculty


Welcome New Faculty

Jennifer Lynn Cook, MD, has joined the University of Arizona Sarver Heart Center as an Associate Professor of Medicine in the Division of Cardiology at the UA College of Medicine - Tucson, and director of Advanced Heart Failure, Mechanical Circulatory Support and Transplant Cardiology at Banner – University Medical Center Tucson.
Dr. Cook, who is board certified in cardiovascular disease and internal medicine, is a fellow of the American Heart Association, where she serves on the Leadership Committee for Clinical Cardiology, as well as the Scientific Sessions Program Planning Committee. She is a Fellow of the American College of Cardiology and a member of their Mechanical Circulatory Support Working Group as well as a member of the Cardiovascular Research Foundation’s Scientific Advisory Board for High-Risk Patient Angioplasty.

Her clinical research interests include application of clinical guidelines into practice. She has been lead author on American Heart Association Consensus Statements for Mechanical Circulatory Support and Acute Heart Transplant Rejection. She also participates in clinical trials for novel drug therapy to help treat heart failure.

“Dr. Cook’s expertise will help the UA Sarver Heart Center build on its legendary history of being a national leader in providing heart-failure patients the fullest range of options and best possible care,” said Nancy K. Sweitzer, MD, PhD, director of the UA Sarver Heart Center and chief of cardiology in the UA College of Medicine – Tucson.
Previously, Dr. Cook was medical director of the ventricular assist device program at Medical University of South Carolina in Charleston.

Following medical school at Southern Illinois University School of Medicine in Springfield, Dr. Cook completed her internal medicine residency at Medical University of South Carolina, and cardiovascular disease and advanced heart failure fellowships at Barnes Jewish Hospital, Washington University School of Medicine in St. Louis.

Brett Colson, PhD, is an Assistant Professor in the Department of Cellular and Molecular Medicine. His research interests include muscle physiology, muscle disease and heart failure. The primary focus of his current research is to study the cellular and molecular mechanisms underlying cardiac muscle dysfunction that occurs with genetic mutations in myosin binding protein-C (cMyBP-C), the No. 1 cause of hypertrophic cardiomyopathy and frequently associated with arrhythmias, heart failure and sudden cardiac death.

After earning his PhD in physiology at the University of Wisconsin, Madison, Dr. Colson did his postdoctoral training as a biophysics research associate at University of Minnesota.

Jason H. Karnes, PharmD, PhD, BCPS, is an Assistant Professor in the University of Arizona College of Pharmacy's Department of Pharmacy Practice and Science. His clinical training as a pharmacist, including board certification in pharmacotherapy and research training in personalized medicine, has put him in a strong position to bridge clinical and basic sciences. He graduated from the University of Florida College of Pharmacy in Gainesville, and continued there to earn his PhD in Clinical Pharmaceutical Sciences followed by postdoctoral research training at Vanderbilt University.

Dr. Karnes' research interests are in cardiovascular pharmacogenomics, specifically investigating the use of genetic polymorphisms to predict serious toxicities of widely used cardiovascular drugs. His ultimate career goal is to facilitate personalized medicine to avoid such toxicities, using electronic medical records research, molecular genetics techniques and prospective clinical studies.
