Professor Berkarda was the first medical oncologist licensed to practice in Turkey and founded the Department of Medical Oncology at Istanbul University in 1974, the Turkish Society of Oncology and the Turkish Society of Chemotherapy. He also served as the Dean of Cerrahpasa Medical Faculty (1979 – 1982) and the President of Istanbul University (1994 – 1998).

In recent years, Prof. Berkarda has focused on researching complementary methods of cancer treatment to be used alongside with the standard orthodox therapeutic protocols, especially for Stage IV patients, as chemotherapy alone is usually ineffective. More specifically, Prof. Berkarda M.D. has been investigating the roles of diet, nutraceuticals, hyperthermia and insulin potentiated chemotherapy to balance the inadequacies of standard treatment procedures.
