Experimental Biology 2021: Q&A with Dr. Michael Tift and Anna Pearson

We are delighted to speak with Anna Pearson (MS student) and her mentor Dr. Michael Tift, Assistant Professor at the University of North Carolina – Wilmington. Anna presented her research “First report of red blood cell lifespan in a marine mammal: An insight into endogenous carbon monoxide (CO) production” at the 2021 Experimental Biology conference last month. What made you interested in studying red blood cells in dolphins?Dr. Tift became interested […]
