Meet the editors

Born in Kolkata (formerly Calcutta) in India, Satyen Saha received his BSc (Chemistry Honors, 1994) and MSc (Chemistry, 1996) from Jadavpur University, Kolkata. He earned his Ph.D. (Photochemistry, 2002) from Hyderabad Central University, Hyderabad, India. Subsequently, he moved to the Department of Chemistry, University of Tokyo, Tokyo, for postdoctoral research (2002–2005) in the group of Prof. Hiro-o Hamaguchi,

followed by postdoctoral research work with Prof. Richard Wiess, Georgetown University, Washington DC, USA. He was the recipient of a JSPS postdoctoral fellowship and a JSPS bridge fellowship for a foreign researcher. At present, he is a Professor in the Department of Chemistry, Institute of Science, Banaras Hindu University (Central University), Varanasi, India. His present research interests are synthesis, structure (solid and liquid phase), and interactions in ionic liquids, NIR emitting materials, ionic liquids, and photophysical studies (steady-state and time-resolved) of fluorescent molecules in condensed phases.

Dr. Ravi Kumar Kanaparthi is a senior assistant professor at the Department of Chemistry, the Central University of Kerala, India. His research group focused on material synthesis for harvesting solar energy (dye-sensitized solar cells), optoelectronic devices, and sensors. Besides, he is also working on the fabrication of fluorescent nanomaterials and studying their photophysics. He is an expert in studying photophysics of materials by

both steady-state and time-resolved fluorescence techniques, fabrication of DSSCs, synthesis of organic and metal nanoparticles, and optical and electron microscopy techniques. He has successfully completed two major research projects received from SERB, Government of India. He has published over twenty-five international/national research articles in peer-reviewed journals and presented his research findings in various national and international conferences. He teaches Quantum Chemistry, Molecular Spectroscopy, and Instrumentational Methods of Analyses to the postgraduate students.

Dr. Tanja V. Soldatović is an associate professor at the Department of Chemical-Technological Sciences at the State University of Novi Pazar. Her scientific focus is on bioinorganic and medicinal inorganic chemistry (studies related to the biological activity and medical application of transition metal antitumor complexes). Dr. Tanja Soldatović is the author and co-author of many peer-reviewed articles and three books. She participated

in the realization of three national scientific research projects and an international DAAD project. Also, Dr. Tanja V. Soldatović was a research fellow at the University of Sassari, Department of Chemistry, Sassari-Italy, and the University of Erlangen-Nürnberg, Inorganic Chemistry, Department of Chemistry and Pharmacy,

Erlangen-Germany. Dr. Tanja Soldatović is a member of the following professional societies: the Serbian Chemical Society, the Association for Cancer Research (Serbia), the European Association for Cancer Research, the Serbian Society for Immunology, and the Molecular Oncology and Regenerative Medicine. Currently, she is head of the Department of Chemical-Technological Sciences at the State University of Novi Pazar.
