I work as the head of neurology and professor of neurology at Joensuu where I also work as a general neurologist at North Karelia Central Hospital. I have mainly studied the epidemiology and phenomenology of neurological disorders in Finland, most often concerning movement disorders, stroke and Multiple Sclerosis. Currently main goals are increasing our knowledge of the epidemiology of neurodegenerative disorders to further uncower their etiologies as well as improving the diagnostics and care of neurological disorders.

I am the first in Italy to have completed a full academic career in Bioinformatics. As a Postdoctoral Researcher, I specialize in bioinformatics, data analysis, network science, and artificial intelligence. I focus on developing and applying machine learning to patient similarity networks for investigating neurological disorders, such as Simpati and StellarPath methods to study Alzheimer’s disease and Stroke. I am particularly interested in networks because they transform complex data into interpretable graphs (helping in pattern recognition), and offer an interpretable and explanative data structure for machine learning algorithms. My experience includes successfully solving real biological problems, collaborating with experts in various scientific fields, and self-learning mathematical and biomedical concepts.

Saara Sillanmäki ([email protected])

I am a medical doctor from Kuopio. My research areas include cardiac imaging and physiology, aortic dilation, and the impact of sleep apnea on the heart. I graduated as a medical doctor from the University of Eastern Finland in 2012, obtained my Doctor of Medicine degree in 2019, and specialized in Clinical Physiology and Nuclear Medicine in 2022.

I have nineteen international publications (JUFO categories 1-3), and I have also written national articles and international textbooks. My doctoral dissertation, completed in 2019, examined the relationship between the electrical and mechanical function of the left ventricle in bundle branch block patients. In this research, I used myocardial perfusion imaging, vector ECG, and echocardiography.

In addition to my clinical work in cardiac imaging (KYS, Imaging Center), I work as a researcher in four research groups: the MOMESY research group investigating modern cardiac magnetic methods (principal investigator), the Heart Surgery Imaging Research Group studying aortic dilation (DilAo, KYS), the STAR (Sleep Technology and Analytics Group, UEF) research group conducting sleep research, and the METSIM research group studying the cardiac effects of the metabolic syndrome. Additionally, I serve as the principal investigator for two projects at KYS: “Detection of Coronary Artery Disease with Micro-Electro-Mechanical Sensors (DECADE, Precordior Oy), a project involving the identification of coronary artery disease using microelectromechanical sensors, and a Horizon2020 project focusing on EU-regulated sleep apnea research. I have also worked as a heart health and imaging expert in a multinational breast cancer radiotherapy study and as a research physician in two multinational cardiac medication studies sponsored by the pharmaceutical industry.

I have actively participated in professional associations. I have served as the Secretary of the Finnish Medical Association’s Clinical physiology and Nuclear Medicine Section since 2015, and I became its chairman in 2018 (continuing). I also served as the Secretary of the Finnish Society of Clinical Physiology from 2016 to 2020. I have had the honor of serving on the Ethics Committee of the Northern Savo Hospital District since 2021 and as the Vice Chairman of the Imaging Section of the Finnish Cardiac Society since 2022. I am also a member of the international education-promoting committee, the Section of Nuclear Medicine of the European Union of Medical Specialists (UEMS), and the European Board of Nuclear Medicine (EBNM) CME Accreditation Committee since 2017.
