Emanuele Rondanina, MSc, PhD

Emanuele Rondanina, MSc, PhD

Application Software Engineer

Emanuele is a biomedical engineer with a PhD in cardiovascular mechanics. He is deeply passionate about developing software technologies that enable smooth and efficient clinical decision making. His academic experience started at the University of Genoa, continued at the Royal Institute of Technology in Stockholm and concluded at the Eindhoven University of Technology. There he was selected as a Marie Skłodowska-Curie fellow for the project “MUSICARE” (MUltiSectoral Integrative approaches to CArdiac caRE). During his fellowship, he developed two modelling tools to predict short- and long-term outcomes of cardiac diseases, generating new insights on cardiac growth and remodelling. In September 2020, he defended his PhD thesis, entitled “Strategies to model cardiac growth”. At CART-Tech, he is working as an Application Engineer, working along with software engineers and physicians to improve image guided therapies.

Scientific Advisory Board

Prof. Steven Chamuleau, MD, PhD

Prof. Steven Chamuleau, MD, PhD

Steven is the head of the Department of Cardiology at Amsterdam University Medical Center (Amsterdam UMC, the Netherlands), specialized in cardiac regenerative therapy, valvular disease and cardiac imaging. He combines state-of-the-art cardiac care with promising experimental techniques and is well known for his implementation of novel treatment strategies and techniques in the clinic.
He completed medical school in Amsterdam and subsequently received his PhD degree cum laude in 2001 on intracoronary derived physiological parameters for clinical decision making at the Academic Medical Center (AMC) in Amsterdam under supervision of Prof. Jan Piek and Prof. Jan Tijssen. After his PhD he started his residency at the AMC Amsterdam, where he also did his fellowship training in cardiology and cardiac imaging. After a year in Louisville, KY, USA in the lab of Prof. Bolli, focusing on cardiac stem cell treatment, he received a position as a staff cardiologist at UMC Utrecht (2008-2019) were he became deputy head of the department, and supervisor for the Cardiology group.
Prof. Chamuleau has published over 200 peer-reviewed papers and is an active member in the Dutch and European Society of Cardiology, and scientific advisory board of the Dutch Heart Foundation, and the International Society of Cardiovascular Translational Research (ISCTR). He is a reviewer for several Journals, including EHJ and Circulation. At the moment he is a (co-)PI in several large international research consortia. He manages a large group of PhD Students, and became Professor of Cardiology at UMC Utrecht in 2016, and since 2020 in Amsterdam UMC.
