Recent News & Events


Thank you to the following faculty members and fellows for promoting Tulane Pulmonary and Critical Care Medicine through their contributions at the annual American Thoracic Society International Conference (San Diego, May 2024)!

Drs. Christine Bojanowski, Joshua Denson, Himmat Grewal and Ross Klingsberg served as faculty along with fellow Dr. Diana Espinoza at the Resident Boot Camp sharing their expertise in Pulmonary and Critical Care physiology, procedures, and medical management!

Tulane faculty members Drs. Christine Bojanowski, Himmat Grewal and Jerry Zifodya additionally chaired and moderated several sessions.

Dr. Zifodya also presented an ATS core curriculum session entitled “ The Road Ahead: The Changing Epidemiology of Tuberculosis”  

Lastly, a big congrats to the trainees and faculty members who contributed to presentations at this year’s conference: Ramsy Abdelghani, Ahmad-Al-Shyoukh, Christine Bojanowski, Paul Chang, Joshua Denson, Brian Deskin, Sarah Dhannoon, Diana Espinoza, Sam Ficenec, Himmat Grewal, Rachel Herr, Joseph Lasky, Nereida Parada, Shigeki Saito, Victor Thannickal, and Jerry Zifodya.


Christine M. Bojanowski, MD MSCR ATSF has been awarded a $500,000 research grant from the Cystic Fibrosis Foundation for her work on upper airway mucosal immunity and Th22 aberrancy in cystic fibrosis (CF).  Dr. Bojanowski’s research aims to characterize the unique immune pathways that make people with CF more susceptible to airway microbial persistence and identify potential therapeutic targets independent of CFTR restoration that will reduce infection and ultimately lengthen life.

Christine M. Bojanowski, MD MSCR ATSF has been invited to serve as Chair of the Professional Development Committee of the American Thoracic Society as part of the society’s newly established Steering Committee on Advancement and Learning (SCALe). The mission statement of SCALe is “to provide pulmonary, sleep, and critical care healthcare professionals with innovative and evidence-based educational opportunities that enhance their knowledge, competence, and performance, ultimately improving patient outcomes and advancing the practice of medicine.”


 Dr. Zifodya

Dr. Zifodya has been awarded a Firland Foundation Research Grant for his grant entitled “Host Clinical and Immunological Risk Factors Associated with Post-Tuberculosis Lung Disease (PTLD) among Kenyan and Ugandan Adults.” He aims to identify subtypes of post-tuberculosis lung disease and their associated risk factors. This grant will fund extended programs for ongoing studies in Kenya and Uganda and continue to build capacity at these study sites.


Dr. Yasin KhanPlease join me in congratulating Dr. Yasin Khan for his recent selection for the competitive Tulane Physician Scientist Pipeline Award! This terrific achievement will undoubtedly help advance Yasin’s research efforts at Tulane!

Yasin’s research focuses on managing acute hypoxemic respiratory failure (AHRF) and understanding how this broader syndrome is related to ARDS. His projects will investigate how mechanical ventilation strategies for ARDS can be extrapolated to patients with AHRF and the clinical outcomes associated with this approach. He is also interested in clinical and cost-effectiveness decision modeling to help optimize the delivery of evidence-based mechanical ventilation to critically ill patients with AHRF.


Milestone Friday! We performed the first two Ion Robotic Bronchoscopies with real-time Philips 3D Cone Beam CT imaging in Louisiana. Nothing better for diagnostic yield and accuracy! Also, we hit 250 total navigational bronchoscopies with cone beam CT! Next goal: 250 Ion + CBCT.
