Profile

ORCID iD: 0000-0002-4737-5817 

Dr. Aivaras Ratkevicius got his PhD in Biology from the Joint Programme of Doctorial Studies coordinated by the Lithuanian Sports University and Lithuanian University of Health Sciences in 1996. He was Guest Researcher at the Copenhagen Muscle Research Centre (University of Copenhagen) from 1993 to 1998. He worked as Assistant Professor at the University of Copenhagen where he did research and teaching in Exercise Biochemistry and Metabolism from 1998 to 2002. Aferwards, he moved to UK and worked as a Senior Lecturer in Sports and Exercise Science at the University of Sunderland. In 2005, Dr. Aivaras Ratkevicius started working as a Lecturer at the University of Aberdeen where he did research and teaching in Sports Science and Molecular Exercise Physiology. In 2016, he was appointed as a Professor at the Lithuanian Sports University where he lead research in the area of Muscles, Motor Control and Health Promotion. He is now a Senior Lecturer in Sports Medicine at Queen Mary University of London. 

Research

Dr. Aivaras Ratkevicius has studied human muscle metabolism using P31-NMR spectroscopy at the University of Copenhagen. He later worked on the role of mitochondrial citrate synthase in metabolism using cell cultures and mouse models. He also did research on the functional role of myostatin in ageing-related muscle weakness and adaptations to exercise training. His research also focused on adaptations of skeletal muscles to caloric restriction and dietary factors. He is now interested in effects of exercise interventions on resting metabolic rate and patterns of leisure time physical activity.
