Dr Niharika Duggal is a new investigator with a long-standing interest in immunesenescence and its impact upon ageing and health. Her research group is focussed on investigating the role of immunesenescence as a contributor to pathological conditions that affect older adults with a higher incidence than the young , such as rheumatoid arthritis , C.difficile infections (CDI) and more recently COVID-19 infections.

Niharika’s research also focusses on the investigating the role of microbiome changes in driving immunesenescence in healthy ageing and during chronic inflammatory conditions. She has received the Springboard award from the Academy of Medical Sciences to investigate the potential of microbiome based interventions in reversing the immune ageing clock.


  • Postgraduate Certificate in Higher Education – University of Birmingham 2021
  • PhD in Immunology: University of Birmingham 2014
  • BSc (Hons) in Biological Sciences: University of Birmingham 2009


Niharika graduated from the University of Birmingham in 2009 with a BSc (Hons) in Biological Sciences. She joined Professor Janet Lord’s lab for her PhD undertaking a project investigating the effects of chronic stress (hip fracture and depression) on the ageing of the immune system. Since completing her doctorate she remained at Birmingham exploring the potential of lifelong physical activity to reverse the immune ageing clock and in 2017 she was awarded the Korenchevsky award by the British Society for Research in Ageing for this work. 

In 2019, she was appointed as a Lecturer in the Institute of Inflammation and Ageing. Her research focuses on exploring the links between immunesenescence and increased risk of autoimmune disorders such as rheumatoid arthritis and the role of regulatory B cells. In addition she has also developed an interest in investigating the contribution of immunesenescence in onset of other pathological conditions, such as C. difficile infections (CDI) and the role of Faecal Microbiota Transplant (FMT) as a potential intervention in these patients.

Postgraduate supervision

Niharika currently supervises doctoral researchers working on the following projects:

  • Gut microbiome dysbiosis and immunesenescence: investigating associations and potential beneficial effects of physical activity
  • Investigating the impact of local anaesthesia on systemic inflammation and immune modulation


Research themes 

  • Investigating the role of immunesenescence as a contributor to the age associated increased risk of chronic inflammatory diseases, such as rheumatoid arthritis (RA) , C. difficile infections (CDI) and COVID-19 infections.
  • Understanding the impact of age associated changes in the gut microbiome in driving immunesenescence and determining vaccine responses.
  • Investigating the potential of microbiome based interventions ( such as Faecal Microbiota Transplantation ) and lifelong exercise in reversing the immune ageing clock.
