Daniel Ehrlich, from Indianapolis, IN, is majoring in Computer Science and Chemistry at Duke University. He currently works with Professor Heather Stapleton, applying analytical chemistry techniques to evaluate environmental health exposures, namely PFAS incidence among firefighters. He is also involved with the NIEHS, under the mentorship of Dr. Nicole Kleinstreuer, using computational toxicological methods to advance in vitro and in silico alternatives to animal testing, primarily focused on cardiovascular health. Driven by a vision to transform precision medicine, Daniel is interested in applying his diverse skillset to the emerging field of mRNA therapeutics. His proposed research in the UK aims to address critical challenges in mRNA design, including optimizing nucleotide modifications to enhance protein expression, reduce dosage requirements, and minimize off-target effects. By improving safety and efficiency, Daniel seeks to make these groundbreaking therapies more accessible, particularly in low- and middle-income countries where advanced medical treatments are often out of reach. As a Marshall Scholar, Daniel plans to pursue an MPhil in Biological Sciences with the MRC Toxicology Unit at Cambridge, under the mentorship of Professor Anne Willis, followed by a joint PhD with the NIH through their OxCam program.
