Tore Eid, MD, PhD

Tore Eid, MD, PhD, is a clinical pathologist and National Institutes of Health-funded researcher.

He diagnoses and monitors conditions including multiple myeloma, substance use, neurological disorders, and metabolic and endocrine disorders through analysis of blood, urine, cerebrospinal fluid, and expert pathology consultations.

Dr. Eid is a professor of laboratory medicine, of neurosurgery, and of cellular & molecular physiology at Yale School of Medicine. His research explores the chemical and metabolic processes that drive brain disorders, with a focus on epilepsy, to advance the development of more precise and effective treatments. One of Dr. Eid’s key discoveries is that deficiency of the enzyme glutamine synthetase in the brain is likely a critical contributor to certain forms of human epilepsy—a finding that has advanced our understanding of the disease’s underlying causes.

His research also encompasses minimally invasive health monitoring, including discovering chemical biomarkers in easily accessible biofluids—such as saliva, sweat, subcutaneous fluid, and breath—to monitor health in real time across a range of conditions, including epilepsy, traumatic brain injury, mood disorders, substance use, diabetes, and cancer.
