Research goal
Our laboratory is dedicated to the interdisciplinary exploration of immuno-biophysical principles, along with the innovative engineering of antibodies to enhance their therapeutic potential across a spectrum of diseases, ranging from infectious diseases to cancer. Combining biophysical methods with molecular and structural biology techniques, our goal is to investigate molecular recognition processes that underlie immune system functions, particularly those occurring within membrane microenvironments. With our comprehensive approach, we aim to contribute novel insights to the field and ultimately foster the development of advanced immunotherapeutic strategies.
