Pediatric dysmorphology and metabolic disorders.
Special interest in neurodevelopmental disabilities, and lysosomal storage disorders.
My main interests are in Lysosomal Storage Diseases, their diagnosis, treatment, and outcomes. In addition, I am involved with research into new developments in Newborn Screening.
Improved Outcome of Prediction in Galactosemic Newborns
To test the hypothesis that total body oxidation of 13C-D-galactose to 13CO2 in breath is a diagnostic and prognostic test for galactosemia. To develop precommercial packaging of a diagnostic kit; an inexpensive cycloidal, gas, dual-isotope mass spectrometer, and normal values in the newborn and very young child.

Center for Lysosomal Storage Disease
To diagnose and study the intervention of enzyme replacement therapy (ERT) for the following lysosomal storage diseases: Gaucher (ß glucosidase deficiency), Fabry (a-galactosidase deficiency), MPS-I/Hurler (a-Iduronisase deficiency), Pompe (acid maltase deficiency), and others.
We are unique in providing ERT both pre- and post- bone marrow/cord blood transplantation in our MSP1/Hurler patients. This is a novel approach with limited clinical experience, and is proving to be very promising in treating patients with reduced lysosomal enzyme activity. We have found that supplying ERT pre-transplant diminishes the toxicity of the procedure (as MPS1 patients tend to have cardiac and pulmonary/airway problems), and the ERT is continued for 2 months post transplant, when the new blood system is developing. Patients are responding well to this treatment.

I am involved in teaching and lecturing residents and medical students about genetic mechanisms and their applications to genetic disorders as seen in patients.
My colleagues and I have desgined a unique human medical genetics course that is given via teleconference. The pilot course was in collaboration with Ponce School of Medicine in Puerto Rico, and ran successfully with 72 students in April and May of 2006. This course, given in both English and Spanish, covered all major areas of medical genetics, and included interactive case presentations, small group discussions and a review workshop.
