With the wide varied nature of care taught within the Division of Pulmonary, Allergy, CriticalCare and Sleep (PACCS) Medicine, our division has multiple overlapping educational responsibilities. We cover medical training for everything from care for asthma, cystic fibrosis and sleep apnea to pulmonary needs of emergency rooms, surgery and intensive care units.

We take a multidisciplinary approach, therefore, in our division to the training we provide formedical students, residents and fellows in all aspects of medical care in those four core areas.

As a number of our faculty also are engaged in translational and other research and have labs at the UA Health Sciences Asthma & Airway Disease Research Center (A2DRC)—formerly the Arizona Respiratory Center, we offer numerous opportunities for those training in our division to participate in cutting-edge research to develop innovative therapeutic and technological solutions to remedy many of the conditions we see in our patients as well.

An additional educational experience we offer to those we train — as well as faculty across the University of Arizona College of Medicine and community physicians in Tucson and Southern Arizona — are seminars and conferences such as the Winter Series Lung Conferences, which we sponsor in cooperation with the UA Respiratory Center.

Lastly, PACCS faculty, fellows, residents and students with an interest in our division are encouraged to read the Southwest Journal of Pulmonary & Critical Care, which is the official publication of the Arizona, New Mexico and Colorado Thoracic Societies. Among associate editors for this open access journal are our current Pulmonary Division chief and  head of sleep medicine, Sairam Parthasarathy, MD; former division chief, Kenneth S. Knox, MD; and Tammer Y. El-Aini, MD. The journal's pages include scholarly work done by our fellows, residents and students as well.

Fellowship Programs

In this division, there are four fellowship programs available for post-residency training and a fifth research track that offers an extra year of intensive research or a dedicated four-year research fellowship for highly qualified individuals:

  1. Pulmonary & Critical Care Medicine 
    Adult Pulmonary Research 
  2. Critical Care Medicine 
  3. Allergy & Immunology 
  4. Sleep Medicine 

The overall goal of our Pulmonary and Critical Care Fellowship Program, like all our fellowship programs, is to offer fellows a balanced clinical and research experience. Our clinical training is enhanced by exposure to a diverse population, subspecialty clinical programs in lung transplantation, interventional bronchoscopy, allergy, and sleep medicine along with a spectrum of basic science and clinical research opportunities.

An embedded Critical Care track is separately accredited by ACGME, offering critical care training to qualified internists, medical subspecialists and emergency medicine physicians.

The Allergy/Immunology fellowship is distinct from the Pulmonary, Critical Care and Sleep programs. This ACGME-accredited program emphasizes excellence in patient care, research and leadership, and will qualify trainees to sit for the American Board of Allergy and Immunology examination.

Our Sleep Medicine fellowship is also ACGME accredited. This fellowship provides the training necessary to qualify to take the multidisciplinary subspecialty examination in Sleep Medicine offered by the American Boards of Internal Medicine, Psychiatry and Neurology and Pediatrics.

For candidates interested in the Adult Pulmonary Research four-year track, this training opportunity is not available through ERAS. Please refer to the “Adult Pulmonary Research" track tab.

Clinical Training Opportunities

As the Pulmonary Division is the largest in the Department of Medicine and overlaps with multiple other medical disciplines, we offer a broad spectrum of interdisciplinary training opportunities in cooperation with other academic departments and clinical units at the University of Arizona and Banner – University Medicine.
