Research interests

Professor Chauhan’s research is clinical and experimental glaucoma. Specific areas of interest include quantification of glaucoma progression to develop clinical tools for decision support and studies of experimental optic nerve damage to guide diagnostics and therapeutics. In both research areas, there is an emphasis on imaging and assessing function.
