Dr Rajesh Kuppusamy

Visiting Fellow

Medicine & Health

School of Optometry and Vision Science

I am a dynamic and innovative researcher, currently pursuing the development of new antibiotics, antivirals, and disinfectants to tackle community and hospital-acquired infections.

Throughout my vast experience in industry and academia, I have developed many novel compounds used to treat important human diseases such as cancer, cardiovascular disease, and bacterial infections. I am passionate about med chem research projects, training new researchers, and translating research into new products, and want to contribute my research for the benefit of working organisations and society.
