Dr. Possick attended Yale University School of Medicine and continued on here to complete a residency in Internal Medicine in 2005 as well as a fellowship in Pulmonary and Critical Care Medicine in 2008.

She is devoted to patient care, student/resident/fellow education, and process improvement, with a focus on comprehensive pulmonary evaluation at the Winchester Chest Clinic, where she is the Medical Director, and as part of the multidisciplinary Thoracic Oncology Clinic in Smilow Cancer Hospital.

Though her clinical practice is quite diverse, she has a particular interest in: the evaluation of the complex pulmonary problems encountered by individuals undergoing treatment for malignancy, particularly pulmonary toxicities related to these therapies; the pulmonary evaluation of patients either being evaluated for or status-post complications from stem cell transplantation; and the management of non-oncologic pulmonary conditions in individuals who are either lung cancer survivors or who are being actively evaluated and treated for lung cancer.

Beyond this focus, she is committed to improving patient/caregiver health literacy, improving transitions of care, and fostering multi-disciplinary collaboration in the care of the multi-morbid population with chronic lung disease. With regards to COPD in particular, she has collaborated in research and care initiatives focusing on the complex issue of high hospital readmission rates after admission for COPD exacerbations.
