Mallory Lennon, a second-year PhD candidate in the Department of Bioengineering at the University of Colorado Denver/Anschutz Medical Campus, has been awarded the National Science Foundation Graduate Research Fellowship Program (GRFP) predoctoral fellowship under the mentorship of Dr. Jeffrey Jacot, Associate Professor of bioengineering. Mallory’s project seeks to understand structural heart development in children born with only one ventricle in the heart, a birth defect known as Hypoplastic Left Heart Syndrome (HLHS), which occurs in about 1,800 births per year in the United States,has a survival rate of only 27% in the first year, and requires several surgeries over many years. Mallory will collect cells from amniotic fluid at the birth of infants with HLHS, make those cells into heart muscle in the laboratory using a recently published technique from the Jacot lab, and measure specific responses to the mechanical forces encountered during development. She expects that this understanding can be matched to genetic signaling and increase the prediction and diagnosis of HLHS as well as suggest future treatments. Mallory obtained her BS in Biomedical Engineering from the Rochester Institute of Technology, graduating Summa Cum Laude. She has previously been a recipient of the American Heart Association summer fellowship, and the TL1 (T32) Pre-doctoral Fellowship from the Colorado Clinical and Translational Science Institute.
