Get to Know Me

I’m a pediatrician, geneticist and genetic researcher, married with a daughter and two cats. I’m also an associate editor for a professional medical genetics journal. I chose to specialize in medical genetics because it has such a central role in many medical conditions affecting patients (young and old).

Why I Treat Children

I chose to be a pediatrician and geneticist in order to help families who are affected by genetic or congenital problems in their child. I enjoy the direct interaction with the families and patients.

What I'm Passionate About

I have an ongoing relationship with the Costello syndrome family support group. Costello syndrome is a very rare condition, and the affected individuals have multiple medical problems including tumor predisposition and intellectual disability.

How I Try to Make A Difference

I am deeply involved in research into genetic disorders, including Costello syndrome and other conditions. I have published numerous papers and received a number of awards for my work.
