received his PhD in 1997 from University of Helsinki under the guidance of Prof. Markku Leskelä. During 1998 - 2003 he worked at University of Helsinki, first as a postdoctoral researcher and then as an Academy researcher, the latter granted by Academy of Finland. In 2003, he was appointed as Academy research fellow by Academy of Finland. In July 2007 he was nominated as a professor of green chemistry at University of Helsinki. During his PhD studies and later career, he has been actively collaborating with Prof. Bernhard Rieger in Technical University of Munich.

His research is focused on the development of inorganic/organometallic chemistry, green chemistry, homogeneous catalysis, especially catalyst development for major chemical transformations including oxidation, reduction, C-H activation, and C-C coupling applied for small molecule activation and biomass valorization.

received her PhD in 2015 from the University of Jyväskylä, where she worked in the group of Prof. Heikki Tuononen studying reactivity of novel main group compounds. After defending her doctoral thesis, she relocated herself to the UK to work as a postdoc in the group of Prof. Simon Aldridge at the University of Oxford. In 2021, she was awarded the prestigious Academy of Finland Research Fellow grant and she is now establishing her own research group in Helsinki. Her main research focus is on experimental and computational investigations of main group and organometallic complexes and their unusual reactivity with small molecules.

My main focus in teaching and research is chemical crystallography, structural chemistry, and X-ray structure analysis, showing the influence of the structure in the solid state, but also in solution, on the chemical and physical properties. This covers a wide area of inorganic chemistry, organometallic chemistry, organic chemistry and supramolecular chemistry.

Since 1994 I’m a Docent for Crystallography at the University of Joensuu and in 2011 I was appointed as a Docent in Inorganic Chemistry at the University of Helsinki.

received her PhD in chemical engineering from the University of Tehran (2021). After the defence, she worked as a process engineer for an oil & gas company in Iran (2021-2023). Currently, she is a post-doctoral researcher in CatLab supervised by Prof. Timo Repo. Her research is focused on Direct Air Capture of CO2 (DAC) by superbase containing compounds. 

Jahir Uddin Ahmad received his PhD in 2012 from University of Helsinki under the guidance of Prof. Markku Leskelä and Prof. Timo Repo. During 2012 - 2013 he worked at Catlab as a postdoctoral researcher. Currently, he is working as a senior researcher on simplified catalytic reactions : 1) Metal-free aerobic oxidation of alcohols and diols 2) catalytic nitration of organic compounds and 4) Catalytic oxidation of biomass. He is also interested on bio-synthesis of metal nano particles catalysts for simplified chemical reactions.

received his PhD, titled “Structural and Functional Studies on Multidimensional Coordination Polymeric Networks”, in 2020 from the Academy of Scientific & Innovative Research (AcSIR), India, conducting his doctoral research primarily at the CSIR-Central Salt and Marine Chemicals Research Institute (CSIR-CSMCRI) under the guidance of Prof. E. Suresh. Following his PhD, from 2021 to 2022, he worked as a CSIR-Research Associate at CSIR-CSMCRI on a project, “Application of Mixed-Linker MOFs Towards CO2 Sequestration and Chemical Sensing of Pollutants”, funded by the Council of Scientific and Industrial Research (CSIR-India).

Subsequently, between 2022 and early 2025, he worked in Japan at Kyushu University and The University of Tokyo, holding positions first as a JSPS Postdoctoral Fellow and later as a Research Assistant Professor on projects, “Creation of MOFs Upconverting Near Infrared Light to Visible Light” and “Realization of multi-exciton control based on rational molecular design”, both funded by the Japan Society for the Promotion of Science (JSPS-Japan).

In 2025, he joined Prof. Timo Repo’s Research Group at the University of Helsinki, Finland, as a Postdoctoral Researcher focusing on rare earth element (REE) recycling. His research interests include developing multifunctional coordination polymers (CPs), metal-organic frameworks (MOFs), MOF-based nanocomposites, and organic macrocycles for applications in environmental remediation (such as sensing/encapsulation of pollutants, CO2 sequestration, catalysis, water splitting, and REE recycling) and photonics (including triplet fusion, singlet fission, photogenerated spin qubits, and quantum information science (QSI)). Furthermore, he possesses expertise in small molecule crystallography and identifies as a chemical crystallographer.

My research focuses on the liquid organic hydrogen carriers that could be used for transportation and storing of renewable energy.

is working on carbon dioxide capture, to lower the amount of carbon dioxide in the atmosphere.  Current research is regarding the use of amidinium and guanidinium superbases to capture CO₂ for either storage or further use in subsequent reactions.  Characterisation of the chemical species will allow for further understanding and tunability for improved performance that can supersede current industrial technologies.

My research work consists of two parts. One is aimed at searching for the reaction mechanism when catalyzing six carbon sugars, then exploring how the coal is formed via chemical reaction. The other is searching for the missing tool for biorefinery, chemicals and materials from renewable feedstock, namely lignin.
