Dr. Antonina Roll-Mecak is a Senior Investigator and Chief of the Cell Biology and Biophysics Section at the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health (NIH). She also holds appointments at the Biophysics Center of the National Heart, Lung and Blood Institute. Dr. Roll-Mecak is a native of Romania who received her undergraduate degree in Chemical Engineering from The Cooper Union in New York City. She earned her Ph.D. in Molecular Biophysics from the Rockefeller University, where she studied the structure and mechanism of translation initiation GTPases. As a Damon Runyon postdoctoral fellow with Ron Vale at the University of California, San Francisco, she identified a new microtubule-severing enzyme. She joined the NIH in 2010. Dr. Roll-Mecak's research focuses on the "tubulin code" hypothesis, which proposes that the combinatorial information expressed through tubulin genetic and chemical diversity controls microtubule dynamics, mechanics, and interactions with effectors. Her laboratory aims to understand: (i) the biochemical mechanisms of tubulin modification enzymes, (ii) the effects of tubulin posttranslational modifications on microtubule properties, and (iii) how these modifications affect cellular effector recruitment and function. Her work integrates structural biology, enzymology, single molecule biophysics, live cell imaging, and computational modeling. Analysis of Dr. Roll-Mecak's recent publications reveals a consistent focus on understanding how tubulin modifications influence microtubule function. Her research spans multiple disciplines including cell biology, neuroscience, structural biology, and biophysics, with particular emphasis on the molecular mechanisms underlying microtubule dynamics and stability. Her work has significant implications for understanding neuropathologies, cancers, and axonal regeneration. Dr. Roll-Mecak has received numerous prestigious awards for her research: Burroughs Wellcome Career Award Pathway to Independence Award from the NIH Searle Scholar Award 2015 Margaret Dayhoff Award from the Biophysical Society 2016 Emerging Leader Prize from the American Society for Cell Biology 2017 Keith R. Porter fellow As Chief of the Cell Biology and Biophysics Section at NINDS, Dr. Roll-Mecak leads a research team that investigates fundamental aspects of microtubule biology. Her laboratory provides training opportunities for postdoctoral fellows and other trainees interested in cell biology, biophysics, and neuroscience. Although specific grant information isn't detailed in the provided text, her receipt of multiple career awards suggests strong funding support for her research program. The Roll-Mecak laboratory at NIH employs a multifaceted experimental approach, combining structural biology, enzymology, single molecule biophysics, live cell imaging, and computational modeling to unravel the complexities of the tubulin code. Her team's work has important implications for understanding neurological disorders, cancer, and cellular transport mechanisms.
