My name is Aleksander GURLO.
I am a Lecturer at the Technical University of Darmstadt in Germany.
My vision is to develop a multi- and interdisciplinary research in the field of materials for energy and environment addressing the challenges of (i) energy harvesting and storage and (ii) environmental protection.
Teaching in general and E-learning and blended-learning in particular is an integral part of my portfolio. In my undergraduate and graduate classes I try to ensure student access, anytime and anywhere to educational material and to promote independent and flexible studying. As a teacher I motivate students, enable them to interpret and analyze data, collaborate in team settings, formulate clear ideas and persuasive arguments, present information clearly in written and oral formats and identify and use additional resources to facilitate problem solving.
