188/4 Electronic Commerce Group

E-Business and E-Commerce include, besides other influencing domains, rapid changes to economic and social processes. For this reason, the E-Commerce group pursues taking an encompassing view at such processes reaching from analyzing enterprises and their respective processes to evaluating the entire market, as well as is active in creating ideas and solutions for meeting the demands of the respective stakeholders.

Overall, the E-Commerce group performs research and creates solutions in the Business-2-Business (B2B) and Business-2-Consumer (B2C) domains. In the B2B domain, the group focuses on (i) business (process) modeling and definition and consequently the specification and implementation of e-business systems while considering and contributing to semantic web research and service-oriented architectures, (ii) ontology engineering and information integration, (iii) "Web Science" focusing on network analysis and content as well as text mining. In the B2C domain, the E-Commerce group performs research targeting (i) visual interaction paradigms as well as (ii) mobile applications. Thereby, our group focuses especially on the development and application of our research in the area of e-tourism and its mobile applications.

Parts of the EC group are working on systems based research, namely on virtualized HPC systems, massive-scale data analytics and energy efficient ultra-scale distributed systems. Our goal thereby is to develop speculative methodologies and techniques to allocate resources in an energy efficient way, but at the same time meet requirements of the end users, like the certain latency of the applications. Our approaches are evaluated quantitatively on different scales by simulations, benchmarks or on experimental clusters. We strive to develop generic methods and methodologies but we let our research be inspired by a set of real world applications from different domains like life science (e.g., DNA sequencing) or social media (e.g., Facebook size data centers).

New members of the EC group

Ivona Brandic (Priv.-Doz. Dr.)
Soodeh Farokhi (MSc.)
Drazen Lucanin (MSc.)
Toni Mastelic (MSc.)

We are pleased to introduce the new members of our group: Ivona Brandic with her three PhD students Soodeh Farokhi, Drazen Lucanin and Toni Mastelic.

Dr. Ivona Brandic is Assistant Professor at Vienna University of Technology (TU Wien). Prior to that, she was Assistant Professor at the Department of Scientific Computing, University of Vienna. She received her PhD degree in 2007 and her venia docendi for practical computer science in 2013, both from Vienna University of Technology. She was involved in the European Union's SCube project (Software Services and Systems Network) and she led the Austrian national FoSII (Foundations of Self-governing ICT Infrastructures) project funded by the Vienna Science and Technology Fund (WWTF). From 2009 to 2013 she was management committee member of the European Commission's COST Action on Energy Efficient Large Scale Distributed Systems. Currently she is management committee member of the European Commission's COST Action on Sustainable Ultrascale Computing (NESUS). From June to August 2008 she was visiting researcher at the University of Melbourne, Australia. Ivona Brandic is on the Editorial Board of the IEEE Transactions on Cloud Computing, IEEE Magazine on Cloud Computing and IEEE Transactions on Parallel and Distributed Systems.

Soodeh has received both BSc and MSc in Software Engineering from Shahid Beheshti University, faculty of Electrical Computer & Engineering in Tehran, Iran. She is a PhD student at Doctoral college “Adaptive Distributed Systems”. She is also a project assistant and working on Self-adaptive Cloud-based Applications (using Control Theory).

Toni was born and raised in Sinj, Croatia. He did his bachelor and masters studies in Computer Science at the University of Split, Faculty of Electrical Engineering, Mechanical Engineering and Naval Architecture (FESB), Croatia. As an Erasmus student he did his Master thesis at Vienna University of Technology.

Drazen finished his bachelor's and master's degree in computer science at the Faculty of electrical engineering and computing, University of Zagreb. Drazen's research focuses on energy efficiency in cloud computing within the HALEY project.
