IMG_694_13I am a postdoctoral research fellow at the Cyber-physical Systems Group of Prof. Radu Grosu at the Institute of Computer Engineering at the Vienna University of Technology.

I finished my Ph.D. with distinction in July 2014 under the supervision of Prof. Bernhard Rinner at the Institute of Networked and Embedded Systems at the Alpen-Adria-University Klagenfurt in Austria. My thesis is entitled ‘Autonomous Distributed Tracking in Networks of Self-organised Smart Cameras’ and was supervised by Prof. Bernhard Rinner. Secondary examinor was Prof. Janusz Konrad from Boston University.

During my Ph.D. I was part of the  of the Pervasive Computing Group and worked on the the European FP7 project EPiCS – short for Engineering Proprioception in Computing Systems. The project consisted of eight partners from across Europe including University of Paderborn, University of Birmingham, ETH Zürich, and Imperial College London but also partners from industry such as Airbus and AIT. The focus of the project is to design complex systems as collections of self-aware and self-expressive nodes.
As part of the team at the Alpen-Adria University my research focuses on self-adaptation and self-organisation of smart cameras within a network to track people or objects in a distributed fashion.
As part of my work within this project, I developed and deployed a smart camera network and implemented a simulation environment for Smart Camera Networks called CamSim. My focus was on distributed tracking of objects in multi-camera networks and applying various algorithms to allow the cameras to self-organise and self-adapt to the given scenario. The project started in September 2010 and was successfully completed in September 2014, receiving best possible grades from the European Commission in all four consecutive years.

My background is in distributed multimedia systems and for my master thesis I worked on identifying spatial relations of digital images based on their common content. I organised and indexed these digital images for further processing in search engines.

In 2011, I joined the Research Group of Prof. Rinner as an assistant professor (‘Universiätsassistent’). In this time I gave various courses. First, Sensornetworks Lab where students work with Oracle SunSPOTS to get an idea of how limited the processing power of single nodes are but how complex systems can get when a set of these SunSPOTS work collectively in a network. The second course is the Pervasive Computing Lab where students aim to implement components of a smart office. Students have the opportunity to come up with their own idea and will face various challenges of pervasive computing. Additionally, I also taught the course Design of Digital Circuits where students learnt about Boolean algebra and VHDL to formally specify digital circuits.
