Clinical research is an important component of our work in the University Malaya Division of Neurosurgery.

Our team is involved in a number of different types of research involving neurosurgical diseases and its management including pre-clinical laboratory research and translational research, as well as interventional and observational clinical trials and technological innovations in surgical practice and teaching.

We hope to identify better ways to diagnose, prognosticate and follow up our patients with brain disorders. We also look at optimising treatment in these patients to improve their quality of life as well as life expectancy.
