Overview
At Case Western
This project focused on creating a database for lymph node sampling with EBUS. Guided by Dr. Zachary Strumpf and
Dr. Sameer Avasarala, we created this database and analyzed lymph node sites for differences in size of
positive/negative nodes. We found a statistically significant change in the 7S lymph nodes that may alter practice patterns.
This project helped me to understand the logistics of clinical research, from generating an idea to submitting a manuscript.
I also learned how to analyze data and be resilient when our plans changed. As a result, I have a better
understanding of how to evaluate current practices and literature, and also contribute to current knowledge through
evidence-based practice.
