# Victor Ambros

> Victor Ambros is the Silverman Professor of Natural Sciences at the University of Massachusetts Chan Medical School and shared the 2024 Nobel Prize in Physiology or Medicine for the discovery of microRNAs, a previously unknown class of tiny regulatory RNAs that control gene expression after transcription. Working with the nematode Caenorhabditis elegans in the early 1990s, Ambros characterized lin-4, a gene that produced not a protein but a very short RNA molecule that base-paired with the messenger RNA of lin-14 to silence it, establishing the founding example of microRNA-mediated regulation of developmental timing. This finding, initially regarded as a worm-specific curiosity, was later shown to reflect a universal regulatory layer present across animals and plants, with hundreds of human microRNAs now implicated in development, cancer, cardiovascular disease, and neurodegeneration. Ambros trained at MIT under H. Robert Horvitz before building independent programs at Harvard, Dartmouth, and UMass Chan, where his lab continues to dissect microRNA function and the broader logic of heterochronic gene networks. His discovery seeded an entire therapeutic industry built on RNA interference and microRNA modulation. For companies marketing sequencing reagents, RNA synthesis, or functional-genomics platforms, his laboratory sits at the historical origin of a still-expanding field with strong NIH funding continuity.
