Dr. Kadera's clinical practice includes general surgical oncology, with an emphasis in soft tissue sarcoma and gastrointestinal malignancies (stomach, small bowel, appendiceal, colon, etc.), including minimally invasive and robotically-assisted surgery.

He trained in general surgery at UCLA, where he spent two extra years doing full-time cancer research. He studied two important reasons why pancreatic cancer is so resistant to chemotherapy, both because of signaling from fibroblasts that support the cancer cell and the cancer cell's ability to stimulate its own growth receptors.

Dr. Kadera then spent two years in surgical oncology fellowship at one of the world's premier clinical and research hospitals, Memorial Sloan Kettering Cancer Center in New York. There, he operated on a high volume of complex surgical cases for sarcoma, gastric, liver, pancreas, and colorectal malignancies, and participated in cutting edge clinical trials.

His laboratory focuses on novel drugs that can target cancer's metabolic machinery, specifically the mitochondria, to cut the source of power and building blocks of the cell.

He is fortunate enough to be married to Samantha Kadera, MD, and is the proud "Papa" to Sienna and Broderick "Brody."

Dr. Kadera is working to improve outcomes in soft tissue sarcoma and GI malignancies by defining molecular pathways that predict local and distant recurrence. He has a particular interest in targeted therapy and the development of neoadjuvant clinical trials.

He is a member of the UCLA Jonsson Comprehensive Cancer Center in the Signal Transduction and Therapeutics program.
