Kalhan received a Bachelor of Arts in history from Brown University. He received his medical degree from Case Western Reserve University School of Medicine, and his Master of Science in clinical investigation from Northwestern University. He completed his internship and residency at the Hospital of the University of Pennsylvania, and his fellowship in pulmonary and critical care medicine at Northwestern.
Kalhan is board certified in internal medicine, pulmonary disease and critical care medicine. [3] He is a member of the American Thoracic Society's clinical problems assembly program committee, and previously served on the society's publications policy committee. He is a fellow of the American College of Chest Physicians. He also serves on the scientific program committee of Chicago Respiratory Society.
He serves as a board member and executive committee member for Respiratory Health Association, [4] and he serves on the association's COPD advisory committee. He is chair of the Illinois COPD Coalition, [5] a network of stakeholders working together to address COPD in Illinois.
Kalhan serves as the director of the asthma and COPD program at Northwestern University, as well as a professor of medicine and a professor of preventive medicine at the Feinberg School of Medicine. He also serves as the medical director of the pulmonary rehabilitation program for the Shirley Ryan Ability Lab in Chicago. He directs a research program focused on chronic obstructive pulmonary disease (COPD) and respiratory epidemiology. Kalhan's research group has been particularly interested in how to define "impaired respiratory health" as part of an overall agenda to determine intermediate phenotypes between ideal respiratory health and chronic lung disease which they argue is essential to intercept chronic lung disease at its earliest stages. [6]
Kalhan was born and raised in Cleveland, Ohio. His parents are Satish C. Kalhan, a physician scientist who spent his career at Case Western Reserve University, and Santosh B. Kalhan a pediatric anesthesiologist who spent most of her career working at the Cleveland Clinic Foundation.

A respiratory therapist is a specialized healthcare practitioner trained in critical care and cardio-pulmonary medicine in order to work therapeutically with people who have acute critical conditions, cardiac and pulmonary disease. Respiratory therapists graduate from a college or university with a degree in respiratory therapy and have passed a national board certifying examination. The NBRC is responsible for credentialing as a CRT, or RRT,
Non-invasive ventilation (NIV) is the use of breathing support administered through a face mask, nasal mask, or a helmet. Air, usually with added oxygen, is given through the mask under positive pressure; generally the amount of pressure is alternated depending on whether someone is breathing in or out. It is termed "non-invasive" because it is delivered with a mask that is tightly fitted to the face or around the head, but without a need for tracheal intubation. While there are similarities with regard to the interface, NIV is not the same as continuous positive airway pressure (CPAP), which applies a single level of positive airway pressure throughout the whole respiratory cycle; CPAP does not deliver ventilation but is occasionally used in conditions also treated with NIV.
Respiratory diseases, or lung diseases, are pathological conditions affecting the organs and tissues that make gas exchange difficult in air-breathing animals. They include conditions of the respiratory tract including the trachea, bronchi, bronchioles, alveoli, pleurae, pleural cavity, the nerves and muscles of respiration. Respiratory diseases range from mild and self-limiting, such as the common cold, influenza, and pharyngitis to life-threatening diseases such as bacterial pneumonia, pulmonary embolism, tuberculosis, acute asthma, lung cancer, and severe acute respiratory syndromes, such as COVID-19. Respiratory diseases can be classified in many different ways, including by the organ or tissue involved, by the type and pattern of associated signs and symptoms, or by the cause of the disease.
Occupational lung diseases are work-related, lung conditions that have been caused or made worse by the materials a person is exposed to within the workplace. It includes a broad group of diseases, including occupational asthma, industrial bronchitis, chronic obstructive pulmonary disease (COPD), bronchiolitis obliterans, inhalation injury, interstitial lung diseases, infections, lung cancer and mesothelioma. These diseases can be caused directly or due to immunological response to an exposure to a variety of dusts, chemicals, proteins or organisms.
Northwestern University Feinberg School of Medicine is the medical school of Northwestern University and is located in the Streeterville neighborhood of Chicago, Illinois. Founded in 1859, Feinberg offers a full-time Doctor of Medicine degree program, multiple joint degree programs, graduate medical education, and continuing medical education.
Bronchitis is inflammation of the bronchi in the lungs that causes coughing. Symptoms include coughing up sputum, wheezing, shortness of breath, and chest pain. Bronchitis can be acute or chronic.
Obstructive lung disease is a category of respiratory disease characterized by airway obstruction. Many obstructive diseases of the lung result from narrowing (obstruction) of the smaller bronchi and larger bronchioles, often because of excessive contraction of the smooth muscle itself. It is generally characterized by inflamed and easily collapsible airways, obstruction to airflow, problems exhaling, and frequent medical clinic visits and hospitalizations. Types of obstructive lung disease include; asthma, bronchiectasis, bronchitis and chronic obstructive pulmonary disease (COPD). Although COPD shares similar characteristics with all other obstructive lung diseases, such as the signs of coughing and wheezing, they are distinct conditions in terms of disease onset, frequency of symptoms, and reversibility of airway obstruction. Cystic fibrosis is also sometimes included in obstructive pulmonary disease.
Pulmonary function testing (PFT) is a complete evaluation of the respiratory system including patient history, physical examinations, and tests of pulmonary function. The primary purpose of pulmonary function testing is to identify the severity of pulmonary impairment. Pulmonary function testing has diagnostic and therapeutic roles and helps clinicians answer some general questions about patients with lung disease. PFTs are normally performed by a pulmonary function technician, respiratory therapist, respiratory physiologist, physiotherapist, pulmonologist, or general practitioner.
Bronchial hyperresponsiveness is a state characterised by easily triggered bronchospasm.
Pulmonary rehabilitation, also known as respiratory rehabilitation, is an important part of the management and health maintenance of people with chronic respiratory disease who remain symptomatic or continue to have decreased function despite standard medical treatment. It is a broad therapeutic concept. It is defined by the American Thoracic Society and the European Respiratory Society as an evidence-based, multidisciplinary, and comprehensive intervention for patients with chronic respiratory diseases who are symptomatic and often have decreased daily life activities. In general, pulmonary rehabilitation refers to a series of services that are administered to patients of respiratory disease and their families, typically to attempt to improve the quality of life for the patient. Pulmonary rehabilitation may be carried out in a variety of settings, depending on the patient's needs, and may or may not include pharmacologic intervention.

Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by long-term respiratory symptoms and airflow limitation. The main symptoms include shortness of breath and a cough, which may or may not produce mucus. COPD progressively worsens, with everyday activities such as walking or dressing becoming difficult. While COPD is incurable, it is preventable and treatable.
