“On this World Milk Day, I find myself reflecting on a journey that I could never have imagined when these photographs were taken. 

I grew up on a family farm. My scientific journey did not begin in a laboratory. It began in the fields and dairy sheds of our family farm, where I learned through practice that every liter of milk represents countless hours of care, dedication, and hard work.

Milk was at the heart of our family’s life. Alongside farm workers, I helped prepare feed for livestock, transport fodder, and milk the cows by hand. My mother would then transform that milk into foods that nourished our family and community. She would prepare whey, lassi, yogurt, cheese, and other dairy products using ‘‘Madhani’’ (wooden churning device). Through these simple but meaningful practices, we were not only producing food but also contributing to the nutrition and well-being of the community around us. 

Years later, after university education, my path led me from the farm to the laboratory. As a scientist, I became fascinated by extracellular vesicles (EVs), tiny biological nanoparticles released by cells that carry proteins, lipids, and genetic information. These nanoscale natural messengers transport biological information between cells throughout the body and are increasingly being explored as innovative tools for precision medicine. What I could not have imagined was that these tiny nanovesicles are naturally present in that same milk which I used to collect from cows and would later become the focus of oral delivery of RNA therapeutics and targeted drug delivery.

Scientific research at the Ludwig Boltzmann Institute for Nanovesicular Precision Medicine (LBI-NVPM) investigates milk-derived EVs as natural nanocarriers, where I am investigating the delivery of RNA therapeutics. Milk-derived EVs offer several unique advantages. They are naturally abundant, biocompatible, bioavailable, scalable, and remarkably well suited for oral administration, making them an attractive platform for next-generation medicines.

I see this convergence of agriculture, biology, and nanotechnology as a reflection of my own journey from the farmyard to the laboratory. This journey reminds me of the remarkable potential hidden within everyday natural products and the exciting opportunities they may hold for the future of precision medicine. On World Milk Day, we celebrate the farmers and dairy communities and the role of milk in nourishing billions of people around the world. At LBI-NVPM, I am proud to be part of this journey, exploring how nature-inspired nanovesicles can help shape the next generation of precision medicines and bring innovative treatments closer to patients.”
