Mihai V. Putz is a laureate in physics (1997), with an MS degree in spectroscopy (1999), and PhD degree in chemistry (2002), with many post doctorate stages: in chemistry (2002-2003) and in physics (2004, 2010, 2011) at the University of Calabria, Italy, and Free University of Berlin, Germany, respectively. He is currently Associate Professor of theoretical and computational physical chemistry at West University of Timisoara, Romania. He has made valuable contributions in computational, quantum, and physical chemistry through seminal works that appeared in many international journals. He is actively promoting a new method of defining electronegativity, DFE (Density Functional Electronegativity), among new enzyme kinetics (Logistic Enzyme Kinetics), and of new structure-activity relationship (SPECTRAL-SAR) model for a unitary quantum approach of the chemical reactivity targeting the bio-, pharmaco-and ecological analytical description. Recently, he is Editor-in-Chief of the International Journal of Chemical Modelling and the International Journal of Environmental Sciences. He is member of many professional societies and has received several national and international awards from Romanian National Authority of Scientific Research (2008), the German Academic Exchange Service DAAD (2000, 2004, 2011) and the Center of International Cooperation of Free University Berlin (2010). He is the leader of the Laboratory of Computational and Structural Physical Chemistry at Chemistry Department of West University of Timisoara, Romania, where he conducts research in the fields of quantum chemistry and quantitative-structure activity relationships (QSAR). In 2010 Mihai V. Putz was declared through a national competition the Best Researcher of Romania.

• SPECTRAL-SAR Algorithm and the Algebraic Correlation Factor. SPECTRAL-SAR Assesment on Ionic Liquids’ Toxicity. Quantum and Statistical Interpretation of SPECTRAL-SAR Method.

”This monograph gathers, through a collection of original papers, the methodology and implementation of the newly QSAR method, built on algebraic means--the SPECTRAL-SAR, with toxicological applications for paradigmatic classes (including ionic liquids) of molecules and aquatic species. The book responds to the currents needs for in silico assessment of the mechanistic interpretation of the ligand-receptor interactions in open systems, especially where statistical analysis provides limited interpretation of the results. Overall, the volume may be regarded as a collection of advanced chapters in computational ecotoxicology equally valuable for graduate students and researchers working in the field of environmental sciences.”--Prof. dr. Vasile Chis, Faculty of Physics, Babes-Bolyai University, Romania“This innovative and well-written book, edited by Prof. Putz, largely expands the OECD QSAR Toolbox available online by introducing new powerful concepts, like the minimum spectral path principle, and new correlation factors to measure chemical–biological interactions. These algorithms constitute the SPECTRAL-SAR approach and achieve ‘spectacular computational results’ in all the studies presented in the book. The book is instrumental for university and chemical industry researchers in their daily jobs in filling gaps in ecotoxicity data needed for assessing the hazards of chemicals.”--Dr. Ottorino Ori, Actinium Chemical Research, Rome, Italy
