In the winter semester, Prof. Dr. Hagen Lauer Teaching and Research at the Department Mathematics, Natural Sciences and Computer Science (MNI) of the Technische Hochschule Mittelhessen (THM). In terms of content, information security and the cyber resilience of critical infrastructures together with aspects of computer forensics and system security represent the core of his professorship for "IT security".

Lauer is a specialist in information security, cyber defense, and the resilience of critical infrastructures, familiar with THM from his student days: He completed his master's degree in computer science in Giessen in 2014. His doctoral thesis, "Security and Trust in Virtualized Environments," submitted to Monash University in Melbourne in 2020, examines the security and trustworthiness of cloud solutions using trusted computing technologies and formal methods for the design and verification of particularly secure complex systems. He used this expertise to initially work in industry, later for the Australian Commonwealth Scientific and Industrial Research Organisation (CSIRO), and most recently at the Fraunhofer Institute for Secure Information Technology (SIT). There, Lauer was Group and Business Unit Manager for "Secure Intelligent Energy Systems" and later Deputy and Acting Head of the Cyber-Physical Systems Security Division.

Most recently, he did research at the Fraunhofer Cluster of Excellence "Integrated Energy Systems" (CINES) and in projects funded by the Federal Ministry of Science on AI-based detection and resilient avoidance of attacks in cyber-physical systems. He also publishes on these topics in international journals, in the specialist and daily press. In his professorship, Lauer would particularly like to bring the results of international research and development to the region and deepen them at the THM .
