Oh has been the principal investigator on multiple clinical trials of chemotherapy in castration-resistant (CRPC) prostate cancer and for three trials of neoadjuvant chemotherapy in high-risk localized prostate cancer patients.

At the Dana–Farber Cancer Institute, from 2000 to 2009, Oh developed and managed a prospective clinical database linked to blood and tissue banks for more than 8,000 prostate cancer patients, with links to blood samples and tissue repositories, for exploration of research and prognostic applications, including: efficacy of various therapies in CRPC, hormonal therapy, testosterone as a marker for cancer outcome, relapse predictions based on nutritional factors at diagnosis and autoantibody signatures, and assessment of pharmacogenomic patterns predicting Gleason score. At Mount Sinai, he continued this work and developed a clinicogenomic database that resulted in multiple publications.
