Educational Background

PhD Integrative Biomedical Research, University of Milan, Department of Biomedical Sciences for Health, 2019

MSc Science, Technique and Teaching of Sport , University of Milan, Faculty of Sport Science, 2014

BPE Physical education, Sport and Health , University of Milan, Faculty of Sport Science, 2012


Dr. Rasica's scientific research experience started with the internship at the Laboratory of Physiopathology of Exercise, Institute of Molecular Bioimaging and Physiology, National Research Council, Segrate (MI), Italy. After gaining a master's degree, she continued in the academic field completing a PhD in Integrative Biomedical Research at the University of Milan.


Areas of Research

Functional evaluation of oxidative metabolism

Dr. Rasica's research areas are mainly focused on exercise physiology and energetic metabolisms, in particular, mechanisms of regulation of muscular oxygen delivery and utilization in different conditions. During her PhD, she investigated the effects of dietary nitrate supplementation on different populations like adolescents with obesity, in healthy subjects and in different conditions including hypoxic environment. Dr. Rasica's main postdoctoral research project aims to investigate cardiovascular function at rest and during exercise in young and older individuals.
