Andy Witt

Andy Witt serves as Professor of Business Informatics with a focus on Digitalization at Hamburg School of Business Administration (HSBA) since September 2023. His academic foundation includes a Computer Engineering degree from Hamburg University of Technology (TU Hamburg) specializing in applied mathematics and physics, followed by doctoral research at the same institution from 2013-2017.

His educational background includes:

• Computer Engineering studies at TU Hamburg with concentration in applied mathematics and applied physics
• Doctoral research (2013-2017) applying nonlinear Schrödinger equations to model extreme ocean wave phenomena

Professor Witt's research spans Nonlinear Dynamics, Cost Engineering, Sustainable Production, Machine Learning, and Big Data Analysis. His work demonstrates a clear evolution from theoretical physics toward industrial applications, particularly in digitalizing production systems and integrating sustainability metrics into cost engineering frameworks. Current research emphasizes AI-driven optimization for sustainable industry practices.

Analysis of his publication history reveals a strategic shift from fundamental wave dynamics research (2019-2022) toward applied industrial informatics (2021-2023), with growing emphasis on carbon footprint quantification, fusion energy economics, and sustainable manufacturing systems. This trajectory reflects his dual expertise in physical modeling and business-oriented digital solutions.

Professor Witt founded and serves as managing director of CALC4XL GmbH, which develops the namesake software platform for integrated product cost and carbon footprint calculation. This venture directly supports his academic mission by providing industry-tested tools for sustainable product optimization, bridging theoretical research with practical business applications in industrial digitalization.
