    Biography

    Dr. Jeremy B. Jacox, MD, PhD, is an Instructor in the Department of Medicine (Medical Oncology) at Yale School of Medicine and a Medical Oncologist at Smilow Cancer Hospital. He earned his bachelor’s degree from MIT before pursuing his MD and PhD at Yale University School of Medicine. Under the mentorship of Dr. Ruslan Medzhitov, Dr. Jacox completed his doctoral studies in immunobiology, focusing on how intracellular circuits based on growth factors regulate macrophage and fibroblast interactions in both homeostasis and melanoma. His work was supported by a Ruth Kirchstein F30 NRSA Fellowship from the National Cancer Institute, and his PhD dissertation work awarded with Distinction and the MD/PhD Prize from Yale.

    Dr. Jacox completed his residency in Internal Medicine at Yale New Haven Hospital through the Physician-Scientist Training Program and continued his specialized training with a fellowship in Hematology/Oncology at Yale Cancer Center. His clinical practice primarily focuses on the treatment of patients with gastrointestinal cancers.

    During his post-doctoral fellowship, mentored by Dr. Mandar D. Muzumdar, Dr. Jacox investigated the impact of obesity and extreme dietary conditions on the development of pancreatic cancer. He also explored how targeting the tumor microenvironment can enhance anti-tumor immunity in pancreatic cancer. His research efforts have been supported by the ASCO Conquer Cancer Foundation Young Investigator Award, the Yale Cancer Center Advanced Training Program for Physician Scientists (T32), and the Yale Center for Clinical Investigation (KL2).

    Dr. Jacox's interests include community service and his faith, DIY (home and auto), and being with his family. Since meeting his spouse on the Yale shuttle bus, they have raised a family of five precious children together, his greatest accomplishment.
