      Present Title & Affiliation

      Primary Appointment

      Assistant Professor, Radiation Physics, The University of Texas MD Anderson Cancer Center, Houston, TX

      Dual/Joint/Adjunct Appointment

      Assistant Professsor, Radiation Physics - Research, The University of Texas MD Anderson Cancer Center, Houston, Texas

      Research Interests

      Through an integrated program spanning conventional radiotherapy, DNA repair, cancer metabolism, mitochondrial signaling, immuno-oncology, and radiopharmaceutical development, my research seeks to define and exploit tumor-specific vulnerabilities to improve the precision and durability of radiotherapy. By combining mechanistic discovery with translational application, I aim to develop rational, biology-driven treatment strategies that maximize tumor control while minimizing normal tissue toxicity.
