I take care of people with complicated hypertension (high blood pressure), chronic kidney diseases, and dialysis treatments. My niche is taking care of pregnant women with kidney diseases and hypertension, as well as complicated hypertension, chronic kidney disease, and dialysis in the hospital setting.

The kidney center here at Duke is nationally well-known, and we see patients from all over, including international patients. I always want my patients to know I am available for them, either through MyChart or if they call the office and ask a question; they'll usually get an answer within 24 hours.

I was inspired to pursue medicine by my father who is a primary care physician in private practice. Even as a child, I understood the special role he was privileged to play in the lives of so many residents in our small community. Though medicine has changed in countless ways since his career started, I believe connecting with patients on a personal level continues to be a key component of a successful patient-physician relationship. I thoroughly enjoy making genuine connections with my patients and their families. I’m excited to be a part of Duke Health and look forward to partnering with my patients and the vast resources offered to me to deliver personalized, high-quality health care. My specific interests include breastfeeding medicine, clinical preventive services and autoimmune diseases. During my fellowship, I completed the Mary Rose Tully Training Initiative, a lactation consultant training program that allowed me to gain valuable clinical skills in providing care to breastfeeding moms and babies.

My clinical interests include general dermatology and autoimmune skin disease. In particular, I am interested in seeing patients with cutaneous lupus erythematosus, vasculitis, and dermatomyositis. I participate in clinical research in autoimmune skin disease in order to better care for these patients. My practice style is to work together with the patient to find the best treatment for the patient’s symptoms and lifestyle. For example, spending time to discuss everyday sun protection strategies with a cutaneous lupus patient can make all of the difference in preventing flares. In addition, I enjoy screening for skin cancer since I also have a background in oncology research. I aim to not only diagnose and treat skin cancers but to identify prevention methods as well. On a personal note, I am a former Duke undergraduate, Duke medical student, and Duke resident, so I can honestly attest to my commitment to serving the Triangle community.
