About Us

Dedicated to the future of care

The Department of Medicine provides residents with a thorough, broad-based education while giving patients individualized care through Feinberg-affiliated hospitals and care sites and conducting high-level basic and clinical research through our 12 specialized internal medicine divisions.

“As with everything we do, whether at the bedside, in the classroom or in the laboratory, we are constantly striving for excellence.”

Marianne M Green, MD

Professor of Medicine (General Internal Medicine and Geriatrics) and Medical Education

Clinically I am interested in the primary care of adults with acute and chronic illness. I value shared decision making with my patients and my role as care coordinator for patients with complex illnesses who see multiple providers. Academically I am interested in competency assessment for both undergraduate medical students and practicing physicians.

Marina Arvanitis, MD

Assistant Professor of Medicine (General Internal Medicine and Geriatrics)

I am a primary care internist and pediatrician, and a health services researcher focusing on health literacy, patient-reported outcomes, and health care quality. I am particularly interested in understanding the life course development of health literacy, the effects of health literacy on individual and family health, and how it can be promoted within families.

Stephen D Persell, MD, MPH

Associate Professor of Medicine (General Internal Medicine and Geriatrics)

I am a health services researcher and primary care internist. My research involves multiple aspects of primary care delivery including the design, implementation and evaluation of electronic health records-based quality improvement tools, practice redesign techniques and methods for clinician performance measurement.

Chad A Mirkin, PhD

Professor of Weinberg College of Arts and Sciences and Medicine (Hematology and Oncology)

Dr. Chad A. Mirkin is the Director of the International Institute for Nanotechnology and the George B. Rathmann Prof. of Chemistry, Prof. of Chemical and Biological Engineering, Prof. of Biomedical Engineering, Prof. of Materials Science & Engineering, and Prof. of Medicine at Northwestern University. He is a chemist and a world-renowned nanoscience expert, who is known for his discovery and development of spherical nucleic acids (SNAs) and SNA-based biodetection and therapeutic schemes, the invention of Dip-Pen Nanolithography (DPN) and related cantilever-free nanopatterning methodologies, On...

Marc A Sala, MD

Assistant Professor of Medicine (Pulmonary and Critical Care)

My primary goal is to provide compassionate, evidence-based care to people with lung diseases or in the ICU. I am a board-certified pulmonologist and intensivist and have sub-specialty interests in cystic fibrosis, bronchiectasis, and lung transplant. During my fellowship, I acquired experience in laboratory science under Jing Liu, PhD, and firmly believe advancement of excellent medicine is only possible through scientific research. To that end, I spend a portion of my time committed to research of lung disease biology.

Robert A Freilich, MD

Clinical Assistant Professor of Medicine (General Internal Medicine and Geriatrics)

preventive medicine, hypertension, diabetes, cholesterol

Sergejs Berdnikovs, PhD

Assistant Professor of Medicine (Allergy and Immunology)

The question of primary interest in my lab is why only select individuals, despite being genetically similar and living in the same allergen environment, are prone to developing allergic disease, and which processes drive this predisposition? To address this, we employ a systems biology approach and bioinformatics to explore whether there is underlying unity in the pathogenesis of seemingly disparate allergic diseases. By synthesizing large volumes of biological data, we link departures from homeostatic conditions (including changes in metabolic, developmental, and endocrine systems) at the ep...

Teresa K Woodruff, PhD

Professor of Obstetrics and Gynecology (Reproductive Science in Medicine), McCormick School of Engineering, Medical Social Sciences and Medicine (Endocrinology)

Teresa K. Woodruff Ph.D. is the Thomas J. Watkins Professor of Obstetrics & Gynecology, the Vice Chair of Research (OB/GYN), the Chief of the Division of Reproductive Science in Medicine, Feinberg School of Medicine, Professor of Molecular Biosciences in the Weinberg College of Arts and Sciences, and Professor of Biomedical Engineering in the McCormick School of Engineering at Northwestern University.
