Our Team

  • Research Technician

    Brian Braumuller

    Research Technician

    Brian received his Bachelor of Arts from Northeastern University in 2024 and completed his remaining premedical coursework at Northeastern University's College of Professional Studies in 2025. Brian aids in a variety of both in vivo and in vitro studies involving targeted radiotherapy and molecular imaging. Brian is interested in molecular imaging techniques that enhance intra-operative tumor visualization and improve the precision of image-guided surgical interventions.

  • Alexandra Campanella

    Research Technician

    Allie graduated in 2024, receiving her BS in Biochemistry at Lafayette College in Easton, Pennsylvania. She started working in the Pillarsetty lab at MSK that same year as a Research Technician.  Her projects focus on developing novel chemical agents to target the androgen receptor in prostate cancer for imaging and therapeutic purposes, maintaining GMP status of PARPi-FL imaging agent to diagnose and classify surgical margins for oral cancer, and developing an antibody-based agent for imaging and therapeutic purposes in rare melanoma subtypes.

    Tullio Esposito

    Research Fellow

    Tullio completed his clinical training as a pharmacist and PhD at the University of British Columbia in Vancouver Canada. His research at MSKCC focuses on how to reduce salivary gland toxicity associated with PSMA-based radiotherapy and using nuclear imaging to better understand and formulate cancer immunotherapies. He holds a Tow Foundation Postdoctoral Fellowship in molecular imaging.

    Teja Kalidindi

    Senior Research Assistant

    Teja received his BS in Pharmaceutucal Sciences from the Sitha Institute of Pharmaceutical Sciences and his MS in Pharmacology from Long Island University. He is currently developing methods to validate radiopharmaceutical theranostic agents in vitro and in vivo with cancer models. Teja was awarded the the 2022 CMIIT Laboratory Professional award for his accomplishments in the lab.

  • Olivia Kunkle

    Research Technician

    Olivia received her BS in Political Science and Biology from Northeastern University in Boston. Before graduating, Olivia studied KRAS mutations in colorectal and pancreatic cancers at Dana-Farber Cancer Institute. She began working as a research technician at MSKCC in February 2025 and has contributed to multiple projects focused on improving the efficacy and safety of radiotracers in several cancer models. She is currently interested in the use of the antibody-drug conjugate, PADCEV for optical and molecular imaging of urothelial carcinoma.

    Rachel Payne

    Graduate Student

    Rachel received her HBS degree in Chemistry from the University of Utah. She is a PhD student in the Pharmacology program at Weill Cornell Graduate School, performing research in the Lewis and Pillarsetty labs. Rachel is interested in how target receptor density may impact tumor response to targeted radiotherapy.

  • Juliana Welk

    Graduate Student

    Juliana received her BS degree in Biology from Stony Brook University in 2022. She is a Pharmacology PhD student at Weill Cornell Graduate School, where she is conducting research in the Lewis and Pillarsetty laboratories. Her thesis work aims to expand the scope of radioimmunoconjugates in heterogeneous prostate cancer using antibody engineering strategies.
