Dr. Castellino is originally from India and received her initial medical training at Grant Medical College in Mumbai, India where she was drawn to the field of infectious diseases by the wide pathology of infections, especially in the face of a mounting HIV epidemic in India. She subsequently moved to New York City to complete a residency in internal medicine, followed by fellowship training in infectious diseases at Mount Sinai Beth Israel Medical Center. She joined the UT Southwestern faculty in 2019.

Prior to joining UT Southwestern, Dr. Castellino served as Chief of Infectious Diseases at the Veterans Affairs Medical Center in Dayton, Ohio, where her work encompassed clinical health care, administration, and health care epidemiology. She successfully initiated several programs to improve patient access to care, including telehealth care, decreasing wait times and decreasing costs of care. She has a strong clinical interest in bone and joint infections, having successfully initiated a multidisciplinary high risk foot clinic that led to a decrease in limb amputations. Prior to leaving the VA she served as the local site investigator for the VA sponsored study Investigation of Rifampin to Reduce Pedal Amputations for Osteomyelitis in Diabetics ( VA INTREPID)
