Dr. Nikos Pinotsis will join the department of Chemistry of the National and Kapodistrian University of Athens in Greece as Associate Professor of Biochemistry in July 2023. Dr. Pinotsis graduated with a degree in Chemistry from the University of Athens in 1995 and obtained a master’s degree in Analytical Chemistry in 1998. In 1999 he joined the group of Dr I. Mavridis at the National Centre for Scientific Research Demokritos for a PhD in crystallography. In 2003 he moved to Hamburg to work as post-doctoral fellow at the EMBL-Hamburg outstation, focusing on proteins of the cardiac muscle. He continued his work on cytoskeletal proteins at the University of Vienna and since 2013 he is working at Birkbeck College, University of London, where currently is the coordinator of the protein crystallography and biophysics laboratories.

Dr N. Pinotsis is using a variety of structural biology approaches to elucidate the architecture and function of biological systems in health and disease. He is an expert in protein crystallography and cryoEM as well as in a variety of biophysical and molecular biology techniques. One of his main focuses is the understanding of the cardiac cytoarchitecture and how protein variants can cause cardiac arrest or pathologies of the heart. He is also working on the (super)complexes of the respiratory chain and their role in disease. In a third project he is focusing on inhibitors of the HIV capsids and more recently on the inhibition of various SARS-CoV-2 components.
