Dr Powell supervises the patch test clinic at the University of Utah. This also entails the teaching of many medical students, dermatology residents, and occupational medicine residents the technique and details of evaluation of contact allergies. He has also been the principle leader in the University of Utah/Ghana dermatology project in which connections with dermatologists and medical providers in Ghana have been established and teaching programs have been initiated. This has lead to the development of a dermatology training program specific for PA’s in Ghana as well as the lecturing of medical students there.
