Beret Fitzgerald, MD
Medical School: University of Minnesota.
Internal Medicine Residency: University of Minnesota.
Who has been your biggest influence on your career path, and why? This is perhaps a cop out to pick two, but Dr. Paul Farmer was an early inspiration for my career in medicine and using my values to guide my career. In residency, Dr. Kelsey Hills-Dunlap was an influential mentor and model of the kind of PCCM doctor I aspire to be.
What recent accomplishment has you feeling most energized? I recently had a paper published. I was on a big team over the last year and a half and learned a lot about study design and how research can influence health policy. The work was meant to continue to help focus infrastructure funding and improving the prevention of respiratory disease transmission. That funding has all been put on pause but I’m feeling fired up that this work does matter.

Selinam Norgbe, MD
Medical School: Creighton University.
Internal Medicine Residency:  Oregon Health & Sciences University.
Who has been your biggest influence on your career path, and why? My uncle was my biggest influence when I didn't want to become a doctor because I was afraid of having a patient's life in my hands. But he encouraged me and told me that no matter what field of medicine I go into, there will always be those concerns, so you should trust the process and do what you are most passionate about.
What recent accomplishment has you feeling most energized?  My recent accomplishment that made me feel most energized was getting a chance to practice medicine in Botswana. There was a sense of accomplishment in being able to practice medicine in low-resource settings and knowing there is still so much we can do with limited resources,  which helped solidify my interest in global health.

Daniel Shyu, MD  
Medical School: University of Missouri.
Internal Medicine Residency: University of Minnesota.
Who has been your biggest influence on your career path, and why?  My dad has been the biggest influence on my career path. He immigrated to the U.S., developed a successful academic career, and was still an amazing dad. Watching his journey has been inspiring, and he’s always encouraged me to follow what excites and motivates me in my career. His constant support and the example he’s set have had a huge impact on the direction I’ve chosen.
What recent accomplishment has you feeling most energized?  Our peripheral vasopressor paper (with Drs. Pendleton and Ingraham) looking at its usage among the MHealth Fairview sites was just published in Annals ATS this month!

Marie Wilson, MD
Medical School: University of Minnesota.
Internal Medicine Residency: University of Minnesota.
Who has been your biggest influence on your career path, and why? There have been so many people that have helped me along the path, it’s impossible to choose a single one! But I am confident it would be a lot harder if I didn’t have so much support from my family and friends outside of medicine to keep me grounded.
What recent accomplishment has you feeling most energized? Finishing (and surviving) residency has me pretty jazzed!

Andrew Hoisington, DO
Medical School: Michigan State University College of Osteopathic Medicine
Residency: University of Chicago (NorthShore, now Endeavor Health).
Mentored Research: Artificial Intelligence Use by Senior Medical Students During Critical Care Clerkship.
Mentors: Kathryn Pendleton, MD & Ron Reilkof, MD.  Division of Pulmonary, Allergy, Critical Care and Sleep Medicine, Department of Medicine.
Artificial intelligence tools such as large language model chatbots are rapidly emerging as potential aids in medical education, offering opportunities to enhance clinical reasoning, case analysis, and decision-making skills. Early studies demonstrate their promise as virtual tutors, yet also highlight critical limitations, including inaccuracies, hallucinations, ethical concerns, and risks of overreliance. Recent surveys show medical students are aware of these challenges and strongly advocate for regulatory guidance and formal training in AI use. To address this need, a novel ICU clerkship assignment was developed that integrates chatbot-based case workups with structured reflection, requiring students to compare their reasoning against AI-generated outputs. This activity, coupled with dedicated teaching on AI capabilities and pitfalls, aims to promote AI literacy, foster critical thinking, and prepare future physicians to engage with emerging technologies in a safe and judicious manner.

Mentored Research: Choices in the ICU: A Retrospective Study Comparing BiPAP and AVAPS Outcomes in Acute Hypercapnic Respiratory Failure Patients.
Research Mentor:  Michael Alter, MD. HealthPartners Regions Hospital.
The primary objective of this study is to conduct a comprehensive comparison between BiPAP and AVAPS in the management of acute hypercapnic respiratory failure within the ICU setting. By analyzing patient outcomes, we aim to identify which non-invasive ventilatory support modality leads to better clinical results, especially in reducing the necessity for intubation. This study seeks to provide clear evidence that can guide clinicians in making informed choices that enhance patient care and optimize resource utilization in the ICU.

Mentored Research: The 8D Lung: Models and Mechanisms for the Study of Idiopathic Pulmonary Fibrosis. Mentor: Angela Panoskaltsis-Mortari, PhD. Division of Pediatric Blood and Marrow Transplantation & Cellular Therapy.  Division of Pulmonary, Allergy, Critical Care and Sleep Medicine, Department of Medicine
Recent advancements in bioengineering and genetics offer unprecedented opportunities to model lung fibrosis with higher fidelity and consequently perform better pre-clinical trials. In this talk I will cover efforts to discover innovative strategies to prevent, halt, or reverse lung fibrosis through precise lung organ modeling, characterization of disease mechanisms and targeted therapeutic interventions. The goal of my research is to establish a novel platform to model lung fibrosis accurately, facilitating detailed studies of disease molecular pathways, and the screening of novel therapeutic compounds. We also aim to better understand the effects of Hippo/Yap pathway aberrancies in lung fibrosis using our novel lung models and human tissue.
