Introduction
I am a research assistant at the IT Center RWTH Aachen University since 2012. My research is focused on service oriented architectures supporting university processes. I received my M.Sc. cum laude in Artificial Intelligence from Maastricht University in 2012. In 2011 I finished my B.Sc. studies in Scientific Programming at FH Aachen University of Applied Sciences. From 2008 until 2011 I worked at IT Center as a software developer and later as a teacher for scripting and programming languages.

Article
Full-text available
New trends like The Internet of Things, Wearables and BYOD pose new challenges to existing IT infrastructure and applications. Especially the increasing amount and heterogeneity of devices demands changes on existing IT systems. Further degrees of automation are required to successfully operate existing IT infrastructure and applications. Many stud...

New approaches to teaching and research require machine readable interfaces as provided by service oriented architectures. Many scenarios in teaching as well as in research demand cooperation between members of universities. Identity federations and federated applications provide some means for collaboration. Current federation services for single...
Conference Paper
By supporting a wide range of eLearning scenarios with an integrated software suite and API, RWTH Aachen University was able to achieve a high standardization, high rate of adoption of technology and seamless integration into various learning processes by teachers and students in the past years. As students emerge to researchers, they are often mis...
Conference Paper
Extracting interoperable metadata from data entities is not an easy task. A method for this would need to extract non-interoperable metadata values first and then map the extracted metadata to some sensible representation. In the case of HDF5 files, metadata annotation is already an option, making it an easy target for extracting these non-interope...
Preprint
Research Data Management (RDM) systems are becoming an essential part of every researcher's academic career. Often, researchers use various resources and web applications to handle their research data, causing complications for maintaining data and assessing research projects against FAIR principles. Consequently, RDM platforms help researchers wit...
Conference Paper
Many provenance systems assume that the data flow is being directly orchestrated by them or logs are present which describe it. This works well until these assumptions do not hold anymore. The Coscine platform is a way for researchers to connect to different storage providers and annotate their stored data with discipline-specific metadata. Thes...

In response to the growth of demand for web services, there is a rapid increase in distributed systems. Accordingly, software architects design components in a modular fashion to allow for higher flexibility and scalability. In such an infrastructure, a variety of microservices are continuously evolving to respond to the needs of every application....
Conference Paper
Many research data management processes, especially those defined by the FAIR Guiding Principles, rely on metadata for making it findable and re-usable. Most Metadata workflows however require the researcher to describe their data manually, a tedious process which is one of the reasons it is sometimes not done. Therefore, automatic solutions have t...
Conference Paper
Full-text available
With CoScInE, the Collaborative Scientific Integration Environment, we present a software platform to allocate and manage IT resources in research projects. While the platform itself does not store any research data, it enables integration of multiple storage resources and allows metadata management across these resources. This supports researchers...

Chapter
Allowing students to use their own devices for electronic assessments allows institutions of higher education to reduce their expenses for specialized computer labs. There are, however, concerns about the security of these kind of examinations if the devices are not fully controlled by the examining institution. In addition to these concerns, sever...
Book
Our daily life is characterized by an increasing number of process supporting IT services. With wireless and mobile networks, all kinds of devices are connected to the Internet and constantly access, collect and exchange data with various IT services to instantly provide information. The increasing volume and heterogeneity of computer devices requi...
Conference Paper

A Moodle-based e-learning system will replace RWTH Aachen University's SharePoint-based e-learning system, which was introduced 10 years ago, within the course of digitizing teaching processes. The strategic background for the university management is that in the competition for students, teaching must become more attractive through innovative form...

Evolutionary changes are often used to gradually increase the quality of a software. However, if back-end systems have to be replaced with different technologies, the resulting changes are more radical. One example for such a change is the migration of database servers from a relational to a document-oriented storage engine. Based on an example app...
Conference Paper

Universities IT service providers are faced with rising demands on existing IT systems and higher degrees of individualization. The challenge thus is to provide services that researchers can use today but that are flexible and sustainable enough to also support tomorrows' research processes. Emerging from previous projects supporting administrative...
Conference Paper
Learning spaces at universities are limited in their capacity, while, providing more such places to students, often imposes quite some problems to the responsible institutions. This leads to problems for the students finding adequate space to conduct their studies on the campus. The consequences are, e.g. large queues of students waiting in front o...

To reduce the impact of security vulnerabilities of Eduroam the Eduroam Device Management was implemented at RWTH Aachen University. The service allows to create device specific credentials to be used as credentials when connecting to the Eduroam network. Users can create credentials, get an overview of their credentials already created and can dis...

At RWTH Aachen University a project aims at improving the support and technical infrastructure for Research Data Management (RDM). In this project the need was identified to provide researchers with a tool to simply upload and save files in a long term archive. Our solution allows the researchers to use a web interface to deliver their data as a si...

Research today is increasingly interdisciplinary and it thrives on collaboration with partners at the home institution, at home and abroad as well as between universities, research institutions and industry. Research projects are therefore far beyond the classical model of bilateral cooperation and design themselves as virtual organizations. For th...
