Andrew Goldstein, PhD

Assistant Professor-in-Residence of Urology, David Geffen School of Medicine at UCLA
Assistant Professor-in-Residence of Molecular, Cell and Developmental Biology UCLA College, Life Sciences

Dr. Goldstein earned his Bachelor of Arts in Biochemistry and Molecular Biology from Dartmouth College and his PhD in Molecular Biology from UCLA in the laboratory of Dr. Owen Witte. He went on to become the inaugural Fellow of the Broad Stem Cell Research Center at UCLA focusing on epithelial stem cell and cancer biology as an Assistant Researcher in the Departments of Urology and Molecular & Medical Pharmacology. Dr. Goldstein’s research is focused on investigating the cell-types, signaling pathways and microenvironmental cues that influence epithelial progenitor cells and promote tumorigenesis and treatment-resistance. The long-term goals of his work are to investigate the cellular and molecular mechanisms that contribute to cancer initiation, progression and treatment-resistance, particularly in prostate cancer. In addition to joining the scientific team of the UCLA Institute of Urologic Oncology and UCLA Prostate Cancer Program, Dr. Goldstein joins the faculty in the UCLA Department of Molecular, Cell and Developmental Biology.
