Research

My research focus are (conceptual) models in a variety of domains and applications. We develop domain-specific languages (DSLs) and methods for domains such as Ambient Assisted Living, Controlling and Finances, Energy, Health, Manufacturing, Internet of Things (IoT), or Smart Homes. The models created with such languages can be used to develop information systems, assistive systems and services and digital twins in an agile model-based way using generators for code synthesis. This website presents selected research topics and related publications. The full list of publications is available on the publications page.

Assistive Systems

Assistive systems provide situational support for human behaviour based on information from previously stored and real-time monitored structural context and behaviour data at the time a person needs or asks for it HMR+19. They provide critical functionality, or ensure safety in potentially dangerous work environments. Research is needed, as most of them are restricted to certain use cases which allows for less reusability. We investigate needed context information MS17, modeling languages used during runtime and to support the engineering MM13, MRV20, MRZ21, and how to automate the engineering of assistive systems.

Selected Publications:

Digital Twins & Digital Shadows

In our understanding, a digital twin consists of a set of models of the system, a set of digital shadows, and provides a set of services to use the data and models purposefully with respects to the original systemDMR+20.

Model-Based Software Engineering of Information Systems

Using a small set of models, it is possible to generate large parts of information systems. With MontiGem, the generator framework for information systems [GMN+20], we have created a tool to support such a process in an agile, model-driven way.

Selected Publications

Modeling Law

Domain-specific languages provide means to formulate law and contracts. This allows to verify plans according to contracts [DHH+20] and to generate related IT systems from law [RMK+21].

Selected Publications

Privacy

Due to the General Data Protection Regulation (GDPR) organizations are obliged to consider privacy throughout the complete development process. In our work, we have created privacy preserving information systems and demonstrated it on an IoT manufacturing use case [MKM+19], we have created an approach for differential privacy for event logs [MKB+19] and we have shown how MDSE can be used to create privacy-preserving IoT systems [MNRV19].
