About Me

I am a board-certified dermatologist and Mohs surgeon with extensive experience in diagnosing and treating skin cancer using a combination of surgical and noninvasive techniques. I care for patients at MSK’s outpatient location in Basking Ridge, New Jersey.

I completed fellowship training in dermatologic surgeries to remove basal cell carcinoma, squamous cell cancer, melanomas, and other skin cancers. In addition, I have an active research program and have published four books on skin cancer and more than 85 publications in medical journals and textbooks. I have also lectured extensively on the prevention, diagnosis, and management of skin cancers.

Since joining MSK Basking Ridge 12 years ago as head of the dermatology program, I have performed more than 5,000 Mohs surgeries and other dermatologic surgeries. MSK Basking Ridge offers the most comprehensive diagnostic and treatment program in New Jersey, providing world-class care to people with skin cancer of all stages and degrees of severity.

Mohs Surgery and Dermatologic Surgery

Among the different types of skin cancer surgeries, Mohs surgery offers the best cure rate. It is a tissue-sparing surgery commonly used to remove basal cell skin cancers and squamous cell skin cancers. Mohs surgery ensures the complete removal of skin cancer cells while preserving maximal amount of healthy surrounding tissue.

Mohs surgery is reserved for people with squamous cell cancers, basal cell cancers, and other skin cancers that are large, growing quickly, or located on the scalp, face, hands, or genital area, where we want to preserve as much skin as possible. It’s also a good option for people with skin cancers that have come back after previous treatment.

During a Mohs procedure, my team and I first identify the location of your skin cancer and give you a local anesthetic to number the area. We wait a few minutes for the numbing medicine to work. Then we remove the skin cancer in thin layers, examining each layer of skin tissue under a microscope to check for any residual cancer cells. When we get to a layer of skin without cancer, that’s when we stop. This approach allows me to achieve the fine balance of removing the entire skin cancer while leaving as much healthy tissue as possible.

A Mohs surgery usually lasts several hours. It could take longer depending on how many layers of skin need to be removed. For more than 90 percent of my patients, I perform the cosmetic repair on the same day.

I am dedicated to providing my patients with the best cosmetic outcomes possible. As with any surgery, Mohs procedures do leave a scar. I strive to minimize the length and width of scars by using the most delicate repair techniques. Oftentimes, I am able to hide scars within different landmarks on the face and fine lines on the skin.

Melanoma Treatment

Aside from performing Mohs surgery, I also treat early melanomas. This is usually a same-day procedure that takes less than an hour. For advanced melanomas where lymph node biopsies are needed, I will refer patients to one of MSK’s excellent surgical oncologists in Basking Ridge or Manhattan.

Diagnosing Skin Cancer

Another important part of my practice is skin cancer screening and detection. I use a combination of noninvasive imaging modalities, such as dermoscopy, confocal laser microscopy, as well as 2-D total-body photography and 3-D total body photography. These advanced diagnostic tools allow me to find skin cancers at their earliest stage while reducing and avoiding any unnecessary biopsies and other invasive procedures.

I see many people with a medical history or strong family history of skin cancer. Most of these people are considered to be at high risk of skin cancer.

Clinical Dermatology Research

I am also actively engaged in clinical research aimed at improving care for people with skin cancer. Some of my specific areas of interest include the development of new noninvasive ways to diagnose skin cancer, the use of nanotechnology and polymer technology in dermatology, the use of antioxidants to improve skin health, and research on new sunscreens to reduce UV damage.

Clinical Trials

As home to one of the world’s top cancer research centers, Memorial Sloan Kettering is typically involved in more than 900 clinical trials at a given time. Currently, clinical trials focused on the conditions I treat are enrolling new patients.

Most major health insurers offer plans that include MSK as one of their in-network providers. If MSK is in-network, it means all our doctors are too. Medicare and New York State Medicaid also provide benefits for care at MSK.
