Minna Niittykoski (minna.niittykoski@uef.fi)

I am senior scientist (Docent/Adjunct Professor) and an initiator of the brain tumor research line which utilizes patient material. The current interest involve malignant brain tumors, particularly glioblastoma. We are determing its characteristics and aiming for the discovery of new cancer biomarkers. In addition, we are using multiple approaches to modeling disease. I have coordinating role in the study which is working in the network manner. More detailed information of biomarkers may benefit patient diagnostics and help to select and design better and more personalized therapies in the future.

Radiation Research Group (RARE)

We use different approaches from exposure assessment and epidemiology to cellular and molecular biology to study the risks of radiation and chemicals to humans and the environment. Our research fields are non-ionizing and ionizing radiation as well as chemicals, and our common interests include genomic instability, joint effects of multiple environmental agents, and risk assessment. State-of-the-art facilities for cell culture, and cell and molecular biology are available as well as access to the animal facilities of the UEF. We have a collaborative Radiation Biology Unit at the Cancer Center of the Kuopio University Hospital (KUH), involving a cell biology laboratory next to a linear accelerator. The collaboration with KUH also offers a possibility to obtain samples from radiotherapy or diagnostic radiology patients.

Saara Sillanmäki (saara.sillanmaki@uef.fi)

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.

Airway research group aims at identifying clinical and molecular factors for better prediction of inflammatory and neoplastic airway diseases, such as non-steroidal anti-inflammatory drug (NSAID) -exacerbated respiratory disease (NERD), asthma, chronic rhinosinusitis and tongue cancer. We use such as next generation sequencing and  artificial intelligence  in analyses of clinical cohorts and randomized placebo-controlled clinical trials.
