Dr. Jen is a neurologist with formal training in neuro-otology, the neurology of hearing, balance, and eye movement control.   She evaluates and treats patients with dizziness due to a variety of causes, spanning very common disorders (for example, benign paroxysmal positional vertigo), vestibular migraine or migraine-associated dizziness suspected to be genetically complex, and other exceptionally rare hereditary neurodegenerative conditions such as episodic ataxia and pontocerebellar hypoplasia.  She sees patients in a subspecialty clinic at the Mount Sinai Hospital.  She works closely with colleagues who perform vestibular testing and vestibular rehabilitation, and she collaborates with surgical specialists in otolaryngology and neurosurgery at Mount Sinai.


Dr. Jen’s clinical focus in neuro-otology is complemented by research performed in her laboratory on the genetic and physiological bases of disorders affecting balance and eye movement control in neurodevelopment and neurodegeneration.  Her research spans many levels, from clinical observation to genetic characterization, cellular and animal studies, and clinical trials, to bring everything full circle back to patients.  The ultimate goal of her research is to improve diagnosis and develop treatments that will improve patient function and quality of life.
