Hendrik Lambrecht is Professor of Industrial Ecology and Quantitative Methods at Pforzheim University. After studying physics in Heidelberg and Lyon (France), he began his professional career in 2003 at the Centre for European Economic Research (ZEW) and the State Institute for Environment, Measurements and Nature Conservation Baden-Wuerttemberg (LUBW). In 2006, he then joined Pforzheim University as a research associate. In 2011, he received his doctorate at the Faculty of Sustainability of the Leuphana University of Lüneburg on the topic of material-flow-based optimization of operational production. After a short time working for the software company ifu Hamburg GmbH, he was offered his current position at Pforzheim University, where he has been teaching in the study programs BW/Resource Efficiency Management (B. Sc.), Life Cycle & Sustainability (M. Sc.) and Operations Research since 2012.
Hendrik Lambrecht is a member of the Institute for Industrial Ecology (INEC) and the Baden-Wuerttemberg Center of Applied Research (BW-CAR). From 2016 to 2019, he was involved as a member of the National Citizens’ Oversight Committee in the search for a site for a repository for highly radioactive nuclear waste. His research activities cover the areas of energy and material flow management, process optimization in an operational context and life cycle assessment with a focus on energy systems.

Hendrik Lambrecht deals with the analysis and optimization of the environmental and climate impact of production and energy systems. He uses methods from energy and material flow management (industrial ecology) and life cycle assessment (LCA). Based on practical applications in operational production and urban systems, he has contributed to the further development of these methods in numerous inter- and transdisciplinary research projects in recent years. At the center are the research questions:
•   How can the multidimensional results of a life cycle assessment be simplified in an expedient way and thus be meaningfully integrated into operational and societal decision-making processes?
•   Which methods (e. g. visualizations) are suitable for the communication of complex scientific results?
•   How must strategies of the energy transition (e. g. e-mobility, hydrogen technology) be evaluated long-term against the background of the currently often disruptive technological change in this field? (Keyword:
consequential LCA)
•   How should one deal with data and model uncertainties in LCA? What are the consequences of uncertainty or variability of model parameters, as well as assumptions made during modeling, on the result of an LCA? What are the implications for the use of such data in decision-making processes?
•   How can methods from operations research be used for the model-based optimization of operational production and urban energy systems, also taking Scope 3 effects (supply chains) into account?
