Olena Pechak received her Bachelor Diploma from the Department of Ecological Engineering of the Energy Saving and Energy Management Institute of the National Technical University of Ukraine “Kiev Polytechnic Institute” in 2005, and her Master Diploma from the same Department in 2007, both with excellent grades and honors. Currently, she is PhD candidate in Laboratory of Industrial & Energy Economics of School of Chemical Engineering N.T.U.A. and her research interests concern energy and environmental policies with the emphasis on climate change issues. Her thesis is related to the project portfolio selection using MCDA taking into account both environmental and economic aspects.
