Dr Singh is a Clinical Associate Professor of Surgery and a Primary Supervisor for the University of Sydney Postgraduate Researchers (HDR/ Higher Degree by Research) in Surgery.

Prof Singh is currently supervising:

5 (Five)

Masters and Doctoral (PhD) candidates.

If you are considering a research degree in ENT (Otolaryngology, Head and Neck Surgery) through the University of Sydney, we recommend you contact us to meet with Prof Singh. The University of Sydney is Australia’s oldest and largest medical school. We have dedicated research funding available. You will be supported by the research facilities of The University of Sydney and the clinical resources of The Western Sydney LHD, including Westmead Hospital, Australia’s largest healthcare campus. Prof Singh has numerous research topics available for motivated researchers. Publication of your results is our priority.

Research focus areas

Prof Singh’s two key focus areas of research are:

  1. Computational Fluid Dynamics (CFD) in the nose and sinuses
  2. Artificial Intelligence (AI) in ENT
