Liam Delfin
(Clinical Study Coordinator III)
Liam graduated from the University of Central Florida with a Bachelor of Sciences in Biomedical Sciences in 2021. Alongside his studies, he worked in the emergency department as a medical scribe during the peak of COVID. He witnessed numerous emergent procedures and restructuring of the hospital system to adjust to the staggering pandemic. Side-by-side with EM residents, he assimilated extensive knowledge about medical decision making in the ED and a detailed tutorial to exceptional care in high patient volumes. 
 
He accepted a position as a clinical research assistant in Florida in 2022 where he developed an immense passion for research. The idea of "advancing the future of medicine" motivated him to become a clinical research coordinator and coordinate over 15 clinical trials in dermatology, gastroenterology, cancer research, medical devices, and liquid biopsies within 2 years. He has worked with numerous Sponsors, including Bristol Myers Squibb, Roche, AstraZeneca, and Sanofi. 
 
With his eyes set on medical school, he wishes to learn the behind-the-scenes of medicine/research with various doctors and medical facilities to understand what it means to be a reputable physician.
