I am a Clinical Assistant Professor of Otolaryngology-Head and Neck Surgery, and Director of Scholarly Concentrations at the IU School of Medicine-West Lafayette campus. Since January 2013, I have taught a different array of courses within the Medical School Phase I curriculum; and several graduate courses in advanced electrophysiology, auditory and vestibular pathology, research methods, and medical audiology at Purdue University.

As part of my administrative role at the West Lafayette campus, I am always looking for ways to enhance our medical education by connecting our students with other departments, offering them, in turn, unique experiences to enhance their medical education.

My interest in the Scholarly Concentration programs comes from the fact I have experienced, firsthand, the benefits of different types of collaborations that can exist between schools and departments, and, because I understand the importance of developing well-trained, clinician-scientists for the benefit of the different populations that form our community.
