I was born in Miastko, Poland in 1961, and am currently an Associate Professor at the Adam Mickiewicz University in Poznan, and a head of Applied Photochemistry Lab. Our scientific research interests have become wider and wider and now are focusing on both pure photochemistry and its applications. First and foremost, a special commitment is given to an ongoing study of photophysics and electronic structure of biologically important isoalloxazines and flavins in particular. Another group of compounds under scrutiny is alloxazines, the major photodecomposition products of flavins, whose hydrogen-bonded complexes are capable of undergoing excited-state double proton-transfer (ESDPT) in the presence of e.g. acetic acid. Currently we are investing a large effort into the ESDPT reaction studies, both in solution and in crystal solids. Among other subjects we are interested in usage of iso- and alloxazines as efficient photosensitizers of singlet oxygen. Our expertise in pure photochemistry and photophysics enables us to efficiently study some of the systems of great practical importance, such as beers, edible oils in general and olive oils in particular, kraft pulps, dental materials and some others. We are particularly interested in light resistance of those products and the usage of modern spectral, photophysical and statistical approaches in order to provide means allowing to certify their origin, and to monitor the effects of light on their consumer value. I am a co-author of more than 120 peer-reviewed publications which are reported in the publication section.
