Profile

I am an Infectious Diseases and General Medicine speciality registrar doctor, and NIHR Clinical Lecturer at the University of Sheffield. My research focuses on neglected tropical diseases, controlled human infection models (CHIMs), and skin immunology, with the long-term goal of advancing vaccine development and improving treatment options for neglected and important infectious diseases.

I trained initially as a pharmacist, before studying medicine (both University of Nottingham). I then went on to undergo specialist training in Infectious Diseases and General Internal Medicine in Sheffield. My doctoral research at the University of York, supervised by Professor Paul Kaye and Professor Charles Lacey, developed the first sand fly–initiated controlled human infection model for cutaneous leishmaniasis (Parkash et al, Nature Medicine, 2024). This work provides a novel platform to accelerate vaccine evaluation and understanding of the early immune response in leishmaniasis. My PhD thesis was awarded ‘Thesis of the Year’ by the Tropical Medicine and Infectious Disease journal. I now also lead the Leishmania section of the Sheffield Diploma in Tropical Medicine and Hygiene.

Alongside my clinical and academic training, I have been awarded competitive academic grants and awards, including the 2025 Young Investigator Award for Excellence in Clinical Research from the European Society for Clinical Investigation. My work combines experimental medicine, human immunology, global health collaboration, and public involvement to address neglected and emerging infections.
