My Areas of Practice

When I joined the department in 2008, I brought five years of clinical experience in dermopathology to the Park Nicollet Dermatology department. I enjoy teaching pathology to dermatologists and residents, having three times received the University of Minnesota Dermatology Department’s Teacher of the Year Award (2006, 2008, and 2011). While I have lectured and published on a variety of topics within the broad field of dermatology, I am particularly interested in melanocyte pathology, inflammatory dermatoses, and immunohistochemistry.
