Audrey Chang, MD

Audrey Chang graduated from Brown University with a bachelor of science in biology, and went on to earn her medical degree from Albert Einstein College of Medicine. She completed a pediatrics residency at Jacobi Hospital and is currently a Sleep Medicine Fellow at Cincinnati Children’s.

Audrey’s research is on the mechanisms driving endothelial inflammation in obstructive sleep apnea. Under the mentorship of Dr. Sanja Jelic, she is studying the effects of obstructive sleep apnea on intracellular cholesterol trafficking in endothelial cells.

Paul Chung, DO

Paul received a Bachelor of Arts in History from Northwestern University. He earned a Master of Arts in Medical Sciences at Loyola University in Chicago, IL and then received his DO from West Virginia School of Osteopathic Medicine in 2014. He completed his internal medicine residency at NorthShore University where he was also a Chief Resident. He then completed a pulmonary/critical care fellowship at Loyola University Medical Center and a sleep medicine fellowship at Northwestern University. He is currently a postdoctoral research fellow supported by a T32 training grant and is pursuing a Master of Science in Clinical Investigation at Northwestern University. 

 

Paul’s research interest is in identifying neurophysiologic biomarkers that can be used to assess and predict clinical outcomes. His recent research focus is in the Down Syndrome population. He is currently involved with a project that will evaluate the microstructure of sleep in Down Syndrome for associations with cognitive outcomes under the mentorship of Dr. Phyllis Zee.

Jennifer Langstengel, MD

Jennifer O'Loughlin Langstengel was born in New York City and raised in Long Island, New York. She received her B.S. in Psychology from Stony Brook University. She then worked for Weill Cornell Medical College running clinical trials in malignant hematology and oncology before going on to attend medical school at Geisinger Commonwealth School of Medicine. She completed internship and residency at University of Iowa Hospitals and Clinics, where she also served an additional year as VA Chief Resident of Quality Improvement and Patient Safety. Prior to beginning fellowship she served as core faculty in the internal medicine residency of Lehigh Valley Health Network in Allentown, Pennsylvania. She is currently a fellow in pulmonary and critical care medicine at Yale University.

She is working on research studying sleep disorders in opiate use disorder as a predictor of relapse under Dr. Klar Yaggi. She is studying subsets within the population analyzing geographic information with regard to sleep disparities and addiction. She is specifically interested in health disparities within sleep medicine. She plans to pursue a career in academic sleep, pulmonary, and critical care medicine.

Brian Locke, MD

Brian earned a Bachelors of Science in Computer Science from University of Colorado in 2009. He earned his MD from the University of Colorado in 2016. He completed Internal Medicine internship, residency, and chief residency at the University of Utah. He is currently a Pulmonary and Critical Care fellow and Masters of Clinical Investigation student at the University of Utah.

Brian is interested in characterizing the causes and impacts of hypercapnic respiratory failure. Specifically, he is interested in understanding how often hypercapnic respiratory failure results from several component causes, as opposed to a single condition, because less is known about the morbidity experienced by these patients and how they ought to be managed. His current project, with primary mentors Drs. Ramkiran Gouripeddi and Krishna Sundar, involves developing a set of criteria applied to health record data, termed a computable phenotype, to accurately identify patients admitted with acute hypercapnic respiratory failure of any cause.  The goal of this work is to enable the creation of cohorts to investigate how comorbidities (such as sleep apnea), medications (such as opiates), and environment (such as ambient air pollution) influence hypercapnia risk.

Janna Raphelson, MD

Janna is a born midwesterner and earned her Bachelor of Science degree in Global Health from the University of Michigan. She then traveled to Montreal, Canada where she completed her medical degree at McGill University. From there she moved to San Diego to train in Internal Medicine at UC San Diego, where she is also currently completing her Pulmonary Critical Care Fellowship.


Janna’s research is aimed at understanding the interplay between obesity and pulmonary disease. Her recent research has focused on Obesity Hypoventilation Syndrome and its correlation with outcomes in bariatric surgery. Under the mentorship of Dr. Atul Malhotra, she plans to continue to study respiratory mechanics in patients with obesity, and those treated for severe obesity both with surgery and pharmacotherapy.

Nataly Sanchez Solano, MD

Nataly earned her medical degree from Pontificia Universidad Javeriana in Colombia, followed by her pediatric residency at Nicklaus Children’s Hospital in Miami. She continues her clinical training as a Pediatric Pulmonology Fellow at University of Texas Southwestern Medical Center from 2021-2023, with the plan to pursue sleep fellowship afterwards.


Nataly’s research is focused on establishing long-term cardiopulmonary and sleep outcomes in adolescents and adults with history of prematurity. Under the mentorship of Dr. Kara Goss, Dr. Ron Mitchell, and Dr. Tanya Martinez, she is conducting a study to evaluate for sleep disordered breathing in late adolescents and young adults with history of bronchopulmonary dysplasia. The goal will be to use the risk factors identified to develop inclusion/exclusion criteria for a pilot study including full polysomnography. Stratification and early intervention for sleep pathology (such as positive airway pressure) may improve outcomes and consequently reduce the risk of cardiopulmonary and metabolic complications associated with chronic lung disease and sleep disordered breathing in this population.
