 TEACHING EXPERIENCE:

 As a clinical attending at teaching institutions for 15 years,  I taught hundreds of medical students, residents, and pediatric cardiology fellows via didactic lectures, daily rounds, a core departmental lecture series, a core divisional lecture series, and one-on-one interaction.

 As a bioengineer/researcher I have mentored more than 40 engineering students in the design, and particularly the user interface, of a wide variety of medical devices, some of which have been used in successful clinical trials (as noted in publications section).

 As a clinical researcher, I mentored most of the St. Christopher’s/Temple pediatric cardiology fellows particularly in experimental design and statistics; I co-authored papers with 5 of the fellows (Abdallah, Singh, Levchuck, Stauffer, Marangi).

 I organized a statistics course for the entire St. Christopher’s Hospital for Children fellowship program.
