Daniel Fitzsimons

Daniel Fitzsimons is an Assistant Professor in the Department of Animal, Veterinary and Food Sciences at the University of Idaho, College of Agricultural and Life Sciences. His research bridges molecular cardiology and veterinary science, focusing on the regulation of cardiac contraction and relaxation in both human and animal models of disease.

Education:

• Ph.D., University of California, Irvine, 1989
• B.S., University of California, Irvine, 1983

Daniel Fitzsimons' research centers on understanding how calcium dynamics and signal transduction pathways—particularly β-adrenergic receptor signaling—modulate ventricular function. He investigates the roles of key contractile proteins like cardiac myosin-binding protein C (MyBP-C) using CRISPR-engineered murine models that mimic human heart diseases such as hypertrophic cardiomyopathy and heart failure. His work also extends to veterinary applications, especially in understanding right-sided congestive heart failure (brisket disease) in cattle, demonstrating a strong translational and comparative approach.

His recent publications (2015–2019) reveal a consistent focus on myocardial contractility, protein phosphorylation, and sarcomeric regulation. The studies employ transgenic models, functional assessments, and molecular techniques to dissect mechanisms of diastolic dysfunction and contractile recovery, primarily published in leading physiology journals like The Journal of General Physiology and Circulation: Heart Failure.
