» Curriculum Vitae:

Philipp completed his compulsory education at BORG Hartberg. After putting his military service behind him he studied Business Informatics (dt.: Wirtschaftsinformatik) and Information and Knowledge Management at Vienna University of Technology and University of Vienna. During his master's study he worked on a variety of software engineering projects for Siemens PSE, Joanneum Research and Octapharma Wien. Furthermore, he gained hands-on teaching experience as teaching assistent (dt.: Tutor) for numerous University courses on UML, XML, Information Systems, Logic-Oriented Programming and Web Services. From August 2005 to July 2006 he worked on the Celtic research project Madeira in the area of P2P network management. After he graduated in autumn 2007 he worked as a research assistant for the Distributed Systems Group at Vienna University of Technology, where he is also doing his PhD (dt.: Doktoratsstudium) in the area of Service-Oriented Computing. With beginning of 2009 Philipp became a university assistant (Univ.Ass.) in the same group. In terms of teaching he is currently engaged in the bachelor-level course Verteilte Systeme and the master-level courses Advanced Internet Techniques, Technologies for Distributed Systems, and Grid Computing.

» Technical Interests:

My research interests include general issues of distributed computing, especially service-oriented computing, SOA, Web Services, P2P computing and network management. I am furthermore very interested in security issues of distributed systems, and general questions of object-oriented programming in Java. In the course of my study and career I have also built up a solid interest in logic-oriented programming, heuristic optimization (evolutionary algorithms, anyone?) and countless other more 'exotic' topics of computer science.

» Scientific Projects:

S-Cube (March 2008 - ongoing) -- 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 (see the S-Cube homepage). S-Cube is a 4-year EU-sponsored research project, with the goal of integrating european research effords in the area of service-based systems. VReSCO (2007 - ongoing) -- In the VReSCO project we are striving to develop a SOA infrastructure that solves a number of challenges that we currently experience in service-oriented computing. Currently we are thinking about QoS aspects, service metadata, REST integration, notifications, service versioning as well as general decoupling of service providers and consumers. Contact me if you are interested in doing practical work ('Praktikum') or your master's thesis in one of the topics mentioned (or any other topic that you may find suitable in the context of a next-generation SoC infrastructure). DAIOS (2007 - ongoing) -- DAIOS is a Web service framework focussed on dynamic and stubless invocation of SOAP and REST services using a message-based interface. The idea of DAIOS is to decouple clients from the services they are using by abstracting from as many details of the target services as possible. The first version of DAIOS has been developed within my thesis. Since then I have released a first (Java-based) version of the research prototype using Google Code (link). We also have a .NET version of DAIOS available (which has not yet been released for time reasons). I am currently extending some aspects of DAIOS as part of my PhD work, and integrated DAIOS withing the larger VReSCO infrastructure. Celtic Madeira (2006 - 2007) -- The goal of Madeira was to provide system technologies for the Network Management environment that are required by Operators to effectively provide high quality network services in the foreseen scenario of vastly increased numbers and technological diversity of network elements and terminals (see the Madeira homepage for details). In a nutshell we developed a P2P-based network management prototype for large-scale telco providers, with special consideration of Configuration Management, Fault Management, scalability and security. Recently, there has been a report on the project in the Austrian FFG Magazin (last page here).

» Random Facts:

A few personal things about me: My Hobbies include snowboarding, playing Warhammer (don't we all love fantasy? no?), everything that is slightly related to the Simpsons, Tennis (well, no, not anymore, but it used to be a hobby at least) and a bunch of other stuff. If you are interested why my publication output is not as high as it might be have a look at QC, PhD Comics, Dilbert, OOTS or XBDC. You just gotta love Web Comics. This is my Last.FM album quilt - just to give you an idea of what Music I listen to (not that you would care, but I post it anyway since it looks cool):
