Research Interest

Green IT / Green Business Process Reengineering

Sustainability and responsible resource exposure has become a major issue in everyday life. Government, customers, and increasing social responsibility force more and more organizations to positively optimize their environmental impact towards a better, livable planet. Therefore, I identify architectures and methodologies that enable organizations to (1) define their ecological characteristics, (2) sense and measure these ecological characteristics, (3) identify, localize and visualize their corresponding environmental impact, and (4) help them to develop appropriate adaptation strategies in order to optimize their collective environmental impact without neglecting the organizations competitiveness.

Projects

Current Project
 

The MIGRATE! project examines how cloud computing can help to increase the energy efficiency of ICT in companies. It aims to develop new methods for the targeted and systematic migration of current ICT systems to energy-efficient clouds.

In MIGRATE!, new models, methods and tools for the migration to clouds are being developed and tested. The approach taken integrates the three value-added stages of ICT infrastructure, methods/tools and services. The research focuses on the description, analysis and simulation of the energy consumption of ICT, the design of complex combined cloud computing services, models of how to proceed in migration projects and the associated business models for ICT service companies.

Previous Project
 

S-Cube, the European Network of Excellence in Software Services and Systems, will establish an integrated, multidisciplinary, vibrant research community. This will enable Europe to lead the software-services revolution, thereby helping shape the software-service based Internet which is the backbone of our future interactive society.
