Theodore Alexandrov is a team leader at the European Molecular Biology Laboratory (EMBL), the Europe’s leading life science laboratory. He is also the head of the EMBL Metabolomics Core Facility and an Assistant Adjunct Professor at the Skaggs School of Pharmacy, University of California San Diego, USA. The Alexandrov team at EMBL aims to reveal the secrets of metabolism in time and space in tissues and single cells by developing experimental and computational methods. The team unites interdisciplinary scientists from biology, chemistry, and computer science as well as software engineers and data analysts. The developed computational methods are integrated into various open-source and industrial software packages. Since 2014, the team develops and provides for free the cloud software METASPACE for metabolite ID in imaging mass spectrometry, used by universities, governmental organizations, and pharma companies. Theodore Alexandrov is a grantee of an ERC Consolidator project focused on studying metabolism in single cells, as well as of various other European, national, NIH, and industrially-funded projects. He has co-founded and scientifically directed the company SCiLS and has over 80 journal publications and 6 patents in the field of spatial and single-cell -omics.
