Personal Statement

Medical genetic evaluations and personalized genetic testing are powerful tools as gene discovery and medical technologies continue to advance at an rapid pace. My goal is to offer my patients the best care, help families and physicians access the most state of the art testing, as well as provide guidance for treatment and preventative health using a multidisciplinary approach. Our geneticists and counselors provide expertise and support for individuals concerned about genetic screening/testing, prenatal counseling, or risk assessments due to family history or ethnic ancestry.

I have the privilege to provide comprehensive clinical genetic evaluations and lifelong care for children and adults at risk for genetic disorders. With my pediatrics background, I help families and referring physicians assess if differences that are noted prenatally, at birth, or during childhood may affect growth and development, as well as identify the causes which could lead to later problems with health, learning, and/or social interaction. All too often, patients are treated by multiple specialists without a clear explanation about the cause of their issues. As a parent, I want to help find answers for those undergoing a stressful diagnostic odyssey and obtain coordinated quality care to meet your child or family's unique needs.

Dr. Cohen cares for families who have or may have genetic concerns, prior to or during a pregnancy as well as after birth. Her clinical interests range from reproductive medicine to a wide range of genetic conditions requiring coordination of care at various ages such as cardiogenetic or neurodevelopmental disorders.  As Co-Director of the ÈÕ±¾avÉ«ÇéƬ Klinefelter Syndrome Care Center (https://urology.weillcornell.org/klinefelter-syndrome), Dr. Cohen works with a multidisciplinary team of specialists caring for children and young adults with X and Y chromosome variations.  She also sees children with clefts and craniofacial disorders as part of the ÈÕ±¾avÉ«ÇéƬ Craniofacial Clinic (http://weillcornellbrainandspine.org/craniofacial). 

Her research focuses on improving medicine utilizing genetic testing and genomic approaches. She is interested in how diagnosing conditions using molecular technology can help improve decision-making and early treatment for families. Dr. Cohen is currently active in ongoing studies with newborn screening and genome sequencing through research collaborations at several academic centers and the New York State Department of Health. She continues to work with several family advocacy and international support groups involving research and treatment for rare diseases.

In addition to clinical work, Dr. Cohen is actively involved in the teaching of medical students, residents and fellows from different departments as well as graduate students in genetic counseling.  She is the program director for the medical genetics residency program at Memorial Sloan Kettering Cancer Center and New York Presbyterian Hospital.  Outside of work, Dr. Cohen enjoys spending time and traveling with her husband and four children.
