Distributed Data Stream Processing in Heterogeneous Environments

Heterogeneous Data Streams, Distributed Fog and Edge Environments, IoT Data and Application Management


Dr. Steffen Zeuch and his Research Training Group concentrate on developing a data management system for the processing of heterogeneous data streams in distributed fog and edge environments. An explosion in both the number and types of connected devices will create novel data-driven applications in the near future. These applications require low-latency, location awareness, wide-spread geographical distribution, and real-time data processing on potentially millions of distributed data sources and potentially millions of simultaneous data processing operations. In some cases these applications have to operate under tight resource constraints with respect to bandwidth, processing power, and energy consumption. The aim is to design a data management system that unifies cloud, fog and sensor environments at an unprecedented scale. This system should host these environments on a unified platform and leverage the opportunities of the unified architecture for cross-paradigm data processing optimizations, to support emerging IoT applications. In order to achieve that, they will collaborate with the members of BIFOLD’Data and Application Management for the Internet of Things Lab (IoT-Lab).

BIFOLD welcomes the first six Junior Fellows

The Berlin Institute for the Foundations of Learning and Data is very pleased to announce the first six BIFOLD Junior Fellows. They were selected for the excellence of their research and are already well-established researchers in the computer sciences. In addition, their research interests show exceptional potential for BIFOLD’s research goals, either by combining machine learning and data management or by bridging the two disciplines and other research areas. The first six Junior Fellows will cover a broad range of research topics during their collaboration with BIFOLD.

New BIFOLD research groups established

The Berlin Institute for the Foundations of Learning and Data (BIFOLD) set up two new Research Training Groups, led by Dr. Stefan Chmiela and Dr. Steffen Zeuch. The goal of these new research units at BIFOLD is to enable a junior researcher to conduct independent research and prepare him for a leadership position. Initial funding includes their own position as well as two PhD students and/or research associates for three years.
