My laboratory is based at the MRC Centre for Molecular Bacteriology & Infection (CMBI) at the South Kensington campus. We study the role of inflammasome signalling networks in host immunity and inflammation. I also have a Satellite Group at the Francis Crick Institute, London.
Inflammasomes are large multimeric signalling scaffolds that activate caspase-1. Inflammasome activation can also require assistance from caspase-4 (also called caspase-11 in the mouse), and caspase-8. Together, these inflammatory caspases launch a robust host defence programme by acting on their targets. My laboratory studies inflammasomes in the context of infection by enteric bacterial pathogens e.g. Salmonella and pathogenic E. coli. We also collaborate with groups within the CMBI to study infections by pathogens such as Mycobacterium and Shigella, and outside Imperial on pathogens such as Toxoplasma gondii.
In addition, inflammasomes can also instigate autoinflammation associated with various modern-day diseases, including the metabolic syndrome, diabetes and cancer. We are also interested in investigating how natural genetic mutations can predispose individuals to inflammation.
Therefore studying them is important not only for obtaining a better understanding of the fundamental principles of the host response, but also for designing better therapeutics in the future.

I am involved in lecture-based teaching and mentoring rotation projects in following courses. If you are interested in a rotation project in my group, please email me and I'll be happy to chat to you. I also conduct Workshops for MRes/PhD students.
1. MRes in MRes Biomedical Research - Bacterial Pathogenesis and Infection
2. MSc in Immunology
3. BSc in Medical Sciences with Immunity and Infection
4. Biomedical Science degrees course on Molecular Basis of Bacterial Infection
5. Workshop on Biological Statistics
6. Workshop on Scientific Writing
If you are interested in our work, rotation projects are available! Please get in touch via email and come and meet me at the Flowers Bldg, South Kensington Campus.
Education and employment history:
I started at Imperial in 2013, before which I was a postdoc at Yale University (New Haven, USA), and integrated MS-PhD scholar at the Indian Institute of Science (Bengaluru, India), and a BSc Microbiology-Biotechnology student at Ramnarain Ruia College, University of Mumbai (India).
