Assistant Professor of Pediatrics

Baylor College of Medicine


My clinical interests include all aspects of non invasive imaging (echocardiography), including research in the field of Congenital Heart Disease, specifically in Doppler tissue analysis, including latest cardio mechanics assessment using strain and strain rate of ventricular function and its impact on myocardial functional. This includes areas such as Cardiomyopathies, post heart transplant surveillance and pediatric heart failure.   Clinical outcomes based on ventricular function assessments and clinical management are other areas of interest.
I am the assigned principal investigator for Texas Children’s Hospital, in a Pediatric Heart Network (PHN) project. This national project has the objective of collecting data to establish normative echocardiographic cardiac measurements for our pediatric population (including all races and ethnicities). 
Another area of interest is to collaborate and participate with South American institutions for the advancement and improvement of non invasive imaging.  Collaborative projects are underway with Mexico DF and Argentina.
