Profile Summary

I am a translational nephrology researcher with over 15 years of international experience across India, Italy, and Denmark, specialising in extracellular vesicle (EV) biology, kidney transplantation, and precision diagnostics. I hold a PhD in Medical Physiopathology from the University of Turin, Italy, and completed a postdoctoral fellowship at Aarhus University Hospital, Denmark, where I led EV-based biomarker studies in a well-characterised kidney transplant cohort. My research programme centres on developing non-invasive liquid biopsy tools using urinary and plasma EV phenotyping — integrating multiparametric flow cytometry, MACSplex multiplexed surface profiling, and nanoparticle tracking analysis with clinical cohort data to identify biomarkers of renal allograft dysfunction, CKD progression, and AKI. I have authored 19 peer-reviewed publications in journals including Kidney International, JASN, Nephrology Dialysis Transplantation, and Medicina. I offer scientific consulting services including manuscript writing and editing, grant proposal development (Horizon Europe, MSCA, ERC), biomarker study design, clinical research coordination, and expert review across nephrology, transplantation, extracellular vesicles, regenerative medicine, and AKI. I have served as Guest Editor for a special issue on Kidney Transplantation Complications in Medicina (MDPI) and as an ad hoc peer reviewer for multiple international journals. I am currently developing collaborative research proposals in uEV diagnostics and precision nephrology with European academic institutions, and am actively engaged in manuscript preparation from a longitudinal transplant cohort study conducted at Aarhus University Hospital. I bring a rare combination of deep laboratory expertise, clinical research experience, international network, and scientific writing ability — making me an effective partner for researchers, institutions, and biotech companies seeking high-quality scientific output.
