Congratulations to Jessica Stark for winning the Pershing Square Sohn Cancer Prize! The award provides $750,000 to support early-career investigators with bold ideas and the potential to transform cancer research.The funding will help Stark’s group develop new kinds of precision immunotherapies that target sugars on the surfaces of cancer cells. These new medicines promise to extend the benefits of precision medicine and the curative potential of immunotherapy to more cancer patients. Stark recently described her work in Nature Biotechnology’s Five Questions series.
