Engineering Sterility.
Advancing Pharmaceutical Innovation.
I am an M.Pharm professional and sterility assurance SME based in Gent, Belgium, with 15+ years of expertise in sterility assurance, contamination control strategy, aseptic processing, and terminal sterilization. As a sterility expert originally from India, I bring a global perspective to advanced therapy manufacturing — including CAR-T and ATMP production.
My career has spanned MSAT Global R&D and plant roles across sterile injectables (liquid and lyophilized), oncology injectables, bacterial vaccines, and cutting-edge cell therapies — always at the intersection of science, quality, and patient safety.
I am the founder of PRES — Pharmaceutical Resource & Education Services — a voluntary, non-profit platform providing free knowledge to pharmaceutical professionals worldwide. Associate member of the Parenteral Drug Association (PDA).

Sharing Knowledge Freely
"Knowledge is not something to be kept — it is something to be shared."
PRES started with a simple thought: the belief that sharing pharmaceutical knowledge is one of the most valuable ways to serve society. Even in today's world, where information seems to be at everyone's fingertips, people still struggle to access reliable knowledge or engage in meaningful discussion.
PRES was my response to that gap — a platform where pharmaceutical resources are freely available, with no cost attached, so that anyone — whether a professional or a curious learner — can benefit. This is a voluntary, non-profit initiative I run alongside my professional work.
I bring to it 15+ years of experience as a sterility assurance subject matter expert in sterile medicines manufacturing — aseptic processing and terminal sterilisation. By contributing freely through PRES, I hope to support professionals, encourage open discussion, and play a small role in making healthcare safer for all.
