Olga Mazuryk obtained her Doctoral degree in 2015. Her PhD thesis focused on the biological activity of ruthenium polypyridyl complexes in relation to their physicochemical and photophysical properties. Since then, she continues to explore the biological activity of metal complexes, mainly Ru compounds, trying to find the origin of their cytotoxic, phototoxic, and antimetastatic activities. In her work, she relies mainly on different in vitro tests with the use of flow cytometry, fluorescence microscopy, varying spectroscopic assays, and other molecular biology analyses, as well as classical spectroscopic methods to investigate the reactivity of metal complexes.

Maria Oszajca obtained her PhD for her work involving the activation of biologically relevant small molecules (NO, O2, H2O2 etc.) on iron porphyrins in 2014. Since then, her scientific interest remained related to the mechanistic elucidation of small molecule activation in biologically relevant systems. Her current work focuses on nitric oxide biochemistry and metal-catalyzed redox modulation of NO signaling. In her work, she uses an array of spectroscopic methods and fast reaction kinetic techniques including stopped-flow and flash photolysis to follow reaction routes and use the collected data to make conclusions with regard to underlying molecular mechanisms for observed processes.

Ilona Gurgul obtained her Doctoral degree in 2022. Her PhD thesis focused on the biological activity of ruthenium polypyridyl complexes, especially with an emphasis on evaluating their antimetastatic effects. Currently, she is continuing to work on the biological activity of metal complexes and has started working on endothelial cells in relation to aberration in their functionality due to senescence. She is applying in her work various in vitro tests including molecular biology analyses. She is the principal investigator of the Miniatura 8 project (title: Study of transition metal content in senescent cells in relation to the development of idiopathic pulmonary fibrosis).
Research Fellow - Volunteer
Przemek completed his PhD in 2024 and is currently a Research Coordinator at Metrodora Therapeutics (NY, USA). His research focuses on analytical biochemistry, with expertise in protein chromatography, protein-ligand interaction studies, protein stability, and ICP-MS. At Metrodora, he coordinates collaborations with external labs, oversees clinical sample analysis, develops bioanalytical protocols, and prepares comprehensive data reports. Przemek remains connected to Jagiellonian University as a voluntary research fellow, serving as an advisor and contractor on scientific projects aligned with Metrodora’s goals.

Ania graduated in biological chemistry from Jagiellonian University in 2024. In her master's thesis, she investigated the interactions between nitroreductases and hypoxia sensors using biophysical and in sillico methods. Currently, she is working on her Ph.D. project concerning new fluorescent sensors for evaluating redox changes in cells. She is also investigating the possibilities of using biomacromolecules for targeted transport. She is the principal investigator of the Perly Nauki II project (title: Hypoxia-activated prodrugs and sensors - affinity for oxidoreductases as a base for designing compounds).
Garduate student
Eryk started studying Medicinal Chemistry at Jagiellonian University in 2022. He is interested in the biological activity of proteins and metal complexes. He participated in the project on the encapsulation of anticancer drugs into microparticles and the evaluation of protein release from microparticles. In 2025, he successfully completed his bachelor's degree with a research project focused on cyclin-dependent kinase inhibitors. Currently, he is involved in in vitro and enzymatic studies aim at eveluating the anticancer activity of metal complexes.

Dr Ewelina Janczy-Cempa
Ewelina Janczy-Cempa obtained her MSc Degree in Chemistry in 2018 from Jagiellonian University. She obtained her Doctoral degree in 2023 at the same University. Her PhD thesis was entitled " The characterization of selective sensors for optical imaging of hypoxia in cancer cells and study of its effect on the anticancer effectiveness of polypyridyl ruthenium complexes". Her scientific interest was mainly devoted to designing sensors for hypoxia assessment and antimetastatic activity of ruthenium compounds.
Dr Michał Łomzik
Michał Łomzik obtained his MSc Degree in Chemistry from Jagiellonian University and Orleans University in France in 2012 through a double-diploma program. He then continued his Ph.D. studies at Jagiellonian University and Lorraine University in France under the BGF Doktorat en Cotutelle program. He defended his PhD entitled “Synthesis and characterization of hybrid drugs based on ruthenium complex moiety and biologically active organic compounds” in 2016. During his doctoral studies, he was the Principal Investigator in the “Diamentowy Grant” program, funded by the Polish Ministry of Science and Higher Education. Since 2017, he has been employed at the Department of Organic Chemistry, Faculty of Chemistry, University of Lodz. Michał’s research primarily focuses on the synthesis of organometallic molecules, particularly ruthenium, osmium, rhodium, and iridium complexes, for their potential anticancer applications.
