Dr. Nissi is a Professor at the Department of Technical Physics at the University of Eastern Finland, Kuopio, Finland. Dr. Nissi leads a research group focusing on pre-clinical quantitative magnetic resonance imaging (qMRI). In 2021, Dr. Nissi also served as a deputy head of the department. The research topics in the group include relaxometry methods, such as various rotating and laboratory frame relaxation methods and imaging strategies, as well as quantitative susceptibility mapping. While the primary field of target applications for qMRI in Dr. Nissi’s group has been musculoskeletal diseases and their diagnostics, the research interests of his group concern especially methodological development of ultra-short echo time / SWIFT imaging sequences as well as image acquisition and reconstruction strategies for various target applications.

The most recent project fundings granted to Dr. Nissi concern development of AI-assisted virtual histology using magnetic resonance fingerprinting (Research Council of Finland, grant #354693), depelopment of rapid quantitative ultra-short echo time MRI methods using primarily the SWIFT sequence and its variants and iterative compressed sensing reconstruction methods (Research Council of Finland, grant #325146) and developing an innovation and development environment for industrial applications of material research using microMRI, consisting of investment of an 11.74 T microMRI device and of various pilot projects on microMRI of agricultural and industrial products (European Regional Development Fund, grants #A73998 and #A74016).
