About Me

I'm a general thoracic surgeon with expertise in minimally invasive surgery in the treatment of lung and esophageal cancers. My clinical interests include primary lung carcinoma, esophageal carcinoma, thymic malignancies, primary tumors of the chest wall, tracheal tumors and secondary lung carcinoma.

I perform Robotic–assisted thoracic surgery procedures for the removal of lung tumors and tumors in the mediastinum. Robotic surgery provides a significant advantage over traditional thoracotomy incisions as it's minimally invasive and promotes rapid healing with fewer infections. Robotic Assisted lobectomy is becoming the operation of choice for early stage lung cancer.

My research interest involves tumor immunology. I have investigated the role of Ciplatin mediated upregulation of CD40 ligand in lung cancer cell lines. CD8 T cells contain the CD40 ligand receptor that promotes cancer cell apoptosis, or programmed death, after binding CD40 ligand. I also perform outcomes research to improve the results of surgical procedures for thoracic malignancies.

In 2015, I was rated in the top 10 percent of physicians in the nation for patient satisfaction. I've published many studies in Nature Medicine, The Annals of Thoracic Surgery, Thoracic Surgery Clinics, The Journal of Thoracic and Cardiovascular Surgery, Journal for Immunotherapy of Cancer and Rapid Communications in Mass Spectrometry.

Here at OSUCCC – James, we work together as a multidisciplinary team to improve patient care and outcomes while striving to find the cure for cancer. It's challenging and rewarding work, and we never stop trying.
