M. Fränzle’s research interests are in modelling, verification, and synthesis of reactive, real-time, and hybrid dynamics in embedded and cyber-physical systems. He has worked on the semantics of high-level modelling and specification languages and on decision problems and their application to verifying and synthesizing real-time and hybrid discrete-continuous systems including settings subject to stochastic disturbances. The complexity barrier rapidly hit by such automated verification and synthesis procedures has been attacked through extending bounded model checking to very expressive temporal logics, branching-time abstractions, and by developing SAT-modulo-theory techniques for arithmetic constraint solving and tailoring them to the specific formulae structures arising in different verification domains and in synthesis. Furthermore, SAT-modulo-theory techniques for arithmetic constraint solving have been extended to the undecidable domain of arithmetic constraints involving transcendental functions and ordinary differential equations as well as to stochastic variants facilitating the fully symbolic analysis of probabilistic hybrid systems. Another major line of research deals with robust notions of system correctness, i.e. with the construction of correctness certificates which remain valid under the ubiquitous kinds of disturbances like, e.g., manufacturing tolerances. Fundamental research on these topics has mostly been pursued within large collaborative research projects, like the Transregional Collaborative Research Center SFB-TR 14 AVACS (Automatic Verification and Analysis of Complex Systems) or recently the Research Training Group DFG GRK 1765 SCARE (System Correctness under Adverse Conditions).
Applied research within, a.o., the recent projects IMoST (Integrated Modelling for Safe Transportation), SaLsA (Sichere autonome Logistik- und Tranportfahrzeuge im Außenbereich), and MoVeS (Modeling, Verification and Control of Complex Systems), as well as within two industrial research contracts with DENSO Automotive and Volkswagen addresses industrial application domains, which range from advanced driver assistance systems (IMoST) via self-driving transportation systems (SaLsA) to demand-response schemes in power supply networks (MoVeS). These lines of applied research are now extended within the Interdisciplinary Research Center Critical Systems Engineering for Socio-Technical Systems, where the safety impact of operator assistance both for maritime and road-bound transportation is investigated in cooperation with the pertinent industry within dedicated living labs.
