Principal Investigator
Professor Stavros Papadokonstantakis is the head of the SustainPSE group and brings extensive expertise in process systems engineering and sustainable chemical processes. He earned his BSc-MSc (Diploma) in Chemical Engineering from the National Technical University of Athens (NTUA), Greece, in 1998, and completed his PhD at NTUA in 2006, focusing on chemical process modeling using artificial neural networks.
From 2007 onwards, Professor Papadokonstantakis worked as a research associate at ETH Zurich, where he made significant contributions to safety, environmental, and sustainability research. From 2014 to 2021, he was an associate professor at Chalmers University of Technology in Gothenburg, specializing in process modeling, conceptual design, and multi-criteria decision-making.
His research integrates techno-economic analysis, life cycle assessment (LCA), life cycle cost analysis (LCC), and hazard analysis to evaluate the economic and environmental sustainability of production systems. His work primarily focuses on biorefineries, industrial symbiosis, and circular economy concepts.
In June 2021, Professor Papadokonstantakis assumed the prestigious Chair of Process Systems Engineering at TU Wien in Austria, where he leads the SustainPSE group. His research continues to focus on process modeling, conceptual design, and holistic evaluation methodologies. By combining performance indicators and multi-criteria decision-making, he aims to assess the economic and environmental sustainability of production systems throughout their entire life cycle. His expertise is particularly relevant to biorefinery design, industrial symbiosis systems, and circular economy strategies.

Post-Doc
Personal Profile: As a trained petroleum engineer, I decided to make a change and transition to the other side. After working in petroleum production and later as a data analyst for the Austrian gas market, I chose to continue my academic career as a postdoctoral researcher at TU Wien, contributing to a carbon-emission-free future through my research. Currently, I am working on developing a tool for assessing the circular economy and exploring solutions for process optimization using machine learning and quantum computing.
Research Topics: Carbon Circular Economy
Quantum Computing for Optimization
Hobbies: Yoga, reading, art, volunteering

Personal Profile: I am a PhD candidate in process engineering at TU Wien. My research project focuses on the integration of CCS/CCU (Carbon Capture, Storage/Utilization) into current and future industrial infrastructures. From cement production to oil refineries and other industrial sectors, I combine prospective life cycle assessment and life cycle cost analysis methods to evaluate the overall value of CCS/CCU integration and explore optimal solutions under various scenarios.
Research Topic: Superstructure-Based Optimization of CCU/CCS
Hobbies: Top-rope climbing, e-mountain biking, badminton.

Personal Profile: I work as a project assistant in the research unit for process plant engineering for bioresources and sustainability at TU Wien. The EU-HORIZON project I am working on focuses on the production of sustainable aviation fuels from waste biomass by combining fast pyrolysis with solar energy (Circular Fuels). My contribution to the project involves exploring the large-scale perspectives of project technologies in alignment with EU targets for sustainable aviation fuels. The collection of relevant data, primarily economic and environmental data, is used for economic and ecological assessments (LCC/LCA), identifying technical and economic barriers to support relevant policy recommendations for commercial-scale production.
Research Topic: Prospective LCA/LCC and Supply Chain Optimization Approach for SAF
Hobbies: Reading, movies, board games, hiking, swimming, traditional dances, listening to music.
