Personal profile


Dr Tushar Choudhary is an EPSRC Interdisciplinary Research Collaboration PROTEUS Postdoctoral Research Associate

Tushar completed his PhD in 2014 on 'Human Retinal and Choroidal Oximetry using Snapshot Multispectral Imaging' at School of Life Sciences, Heriot Watt University and School of Physics and Astronomy, University of Glasgow. The main objective of his PhD was to develop and validate a non-invasive technique for retinal and choroidal oximetry. The ability to perform oximetry in retinal vessels in vivo, provides a potential advantage in studying and assessing retinal circulation in health and various diseases like diabetes, glaucoma, hypertension and cerebrovascular disease linked to stroke. During the PhD Tushar has also worked on Choroidal and Spinal Cord Oximetry using the same technology.

In 2014, Tushar continued working in Heriot Watt University as Postdoctoral Research Associate in Proteus Project, where he is working on developing in vitro and in vivo biological models and assays to test the imaging and sensing systems developed in Proteus. Tushar is also involved in developing fiber based pH and oxygen sensing probes for clinical system and using fluorescence lifetime imaging microscopy (FLIM) for bacterial detection in lung infection.
