Soy endocrinólogo pediátrico en University Health y profesor adjunto en la división de endocrinología pediátrica y diabetes de UT Health San Antonio.
Entre mis intereses se encuentra el estudio de la diabetes relacionada con la fibrosis quística (CFRD) y otros trastornos endocrinos asociados a la fibrosis quística. La mayor parte de mi investigación y mis presentaciones se han centrado en mejorar la detección, el diagnóstico y el manejo de la CFRD.
Durante los últimos siete años, he colaborado con el director y el personal del Centro de Fibrosis Quística en el desarrollo de una clínica multidisciplinaria para pacientes con CFRD dentro del Centro de Fibrosis Quística. Soy el endocrinólogo encargado de atender a los pacientes adultos con fibrosis quística que padecen trastornos endocrinos. Cuento con una beca de investigación KL2 y una beca de investigación multicéntrica que colabora en el reclutamiento y el tratamiento de pacientes con problemas de diabetes relacionados con la fibrosis quística.
Intereses de investigación:
  • Monitoreo continuo de la glucosa en pacientes con diabetes tipo 1 y fibrosis quística
  • Detección, diagnóstico y tratamiento de la diabetes relacionada con la fibrosis quística
