Biography

I am a passionate Research Scientist with a robust background in microbiology, currently focused on Bacterial Extracellular Vesicles.

I am a Quadram Institute Bioscience Fellow focused on understanding the intricate relationship between the gut microbiome and essential nutrients, particularly iron. My research combines microbiological, biochemical, and computational approaches to uncover how the gut microbiota processes dietary iron, with the ultimate goal of developing novel strategies to improve health and address nutrient deficiencies.

With my fellowship at the Quadram Institute, I investigate how an important group of gut microbes acquire, store, and metabolize iron, exploring its implications for human health. This work has broad potential applications, from enhancing dietary supplements to understanding the microbiome’s role in managing diseases influenced by iron metabolism.
