Dr. Pereira is a translational physician-scientist with clinical expertise in cardiomyopathies, heart failure and heart transplant. His research work has spanned the spectrum of NIH funded population-based studies demonstrating the association of genetic variants with biomarkers, adverse drug responses to basic science investigation in the laboratory determining the functional significance of genetic variation identified in these population based studies to performing NIH funded clinical trials to evaluate the utility and applicability of genetic variants that could modulate drug response in clinical practice. His work has led to the identification of potential biomarkers and therapeutic targets in heart failure.
