Research Interests

Pediatric Dermatology

Clinical investigations include the use of new and existing therapies for the treatment of common pediatric skin diseases, including atopic dermatitis and acne vulgaris. Also, clinical research focuses on evaluating safety and efficacy in the treatment of cutaneous diseases in children.

 Acne Vulgaris

We are continuously conducting mild,moderate and/or severe acne vularis studies to enhance the treatment options for teens and adults who suffer from acne. The studies have involved several combinations of investigational and/or FDA approved topical and/or oral medication.
