Senior Research Associate, Preclinical Pharmacology

Run in vivo studies that move Nurix's degrader programs toward the clinic. You'll execute mouse efficacy, PK/PD, and mechanism-of-action studies in oncology and inflammation models and generate the Western blot and flow cytometry data that show how our molecules work.
