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 in 2013 he moved to Birkbeck College, University of London, where he worked on projects related to bacterial infection and complexes of the mitochondria respiratory chain. 

Dr N. Pinotsis is using a variety of structural & molecular biology approaches, mainly protein crystallography and cryoEM, to elucidate the architecture and function of biological systems in health and disease. 

1. Structural Biology of the cardiac mucls. We are looking on molecular and structural details of the cardiac muscle and how protein variants affect the cytoarchitecture and can cause serious heart deseases such as cardiac arrest. 

2. The mitochondria resprisatory chain. We are focusing on the mechanisms and interactions of complexes and supercomplexes of the respiratory chain in the intter membrane of the mitochondria.
