Our group has an open position for a PhD student in the area of wireless networking and Edge AI. The research focus will be on

  1. low-latency, adaptive wireless networking (Wi-Fi 6, 4G, 5G) and
  2. Edge AI

to intelligently connect and control autonomous vehicles, in particular autonomous ferries. As a system research group, we focus new protocols, systems architectures, and experimental evaluation.

An applicant should bring a Master’s Degree in Computer Science (or related fields). Suggested background and interest includes distributed and networked systems, wireless networking, edge computing, and artificial intelligence. 

The application deadline is 31.05.2021. The suggested starting date is flexible and the position is fully funded (100% E13). Initial recruitment is limited to roughly two years with the possibility for extension. The starting salary depends on qualification etc. but can be estimated to a gross salary of about €4000 per month. German is not a requirement for the position. Official ad (in German) under the headline "Wissenschaftliche*r Mitarbeiter*in am Institut für Informatik". The position is a research position and it does not include teaching duties. 

Please send your applications (CV, letter of motivation, transcripts with grades, names of references /recommendation letters etc.) by email to Olaf Landsiedel. He is also available for questions about the position. 

In the following, selected information about PhD studies and the research environment.

About Kiel University

As Schleswig-Holstein's only fully-fledged university with 27,000 students and more than 2,000 scientists, Kiel University (CAU) offers a cross-disciplinary academic environment. The disciplines offered by its eight faculties are connected by constant dynamic interfaces that are reflected in the university's teaching and integrative research profile. There is close cooperation between the Gustav-Radbruch-Network for Environmental Philosophy and Ethics and all university institutes. This is where ethical issues are discussed which go beyond disciplinary boundaries.

In 2008, four priority research areas were established, based on intensive collaboration: Kiel Life Science, Kiel Marine Science, Kiel Nano, Surface and Interface Science, as well as Societal, Environmental and Cultural Change. Each research area combines the expertise from various faculties - from natural sciences, social sciences, engineering, law and humanities. Today, the priority research areas are firmly embedded in the university’s structures. They complement the wide range of individual research in the various subjects, and form the basis for the Clusters of Excellence "ROOTS - Societal, Environmental and Cultural Connectivity in Past Societies" and "Precision Medicine in Chronic Inflammation (PMI)".

In parallel to this, shared research infrastructures evolved, such as a cleanroom, a lab for analysing ancient DNA, a platform for molecular in-vivo imaging or Europe’s largest scientific Next-Generation-Sequencing-Platform. A shared Computing Centre provides high-performance computer systems and storage services, and develops sophisticated strategies for managing research data.

About living and working in Kiel

About living and working in Germany

Department of Computer Science

In 1971, our department was founded as one of the first departments of Computer Science in the Federal Republic of Germany and has since been the focal point of research and educational activities in Computer Science at the Kiel University. Currently, the department consists of 19 working groups, covering all central aspects of computer science, business information technology and parts of algorithmical and numerical mathematics. The department offers bachelor and master programs in Computer Science and related disciplines as well as PhD studies. 

Distributed Systems Research Group

As a research group, we do -- mainly data-driven -- systems research and focus on Networked and Distributed Systems (in German: Vernetzte und Verteilte Systeme).  We are particularly passionate about the Internet of Things (IoT), Edge Computing, Edge AI, Autonomous Systems, Smart Cities, Industry 4.0. We love to build systems, play with them (=run experiments & write papers) and invite others to play with them, too, by releasing our results and code to the public. The group is lead by Olaf Landsiedel. As of today, the group consists of four PhD students, a PostDoc, as well as a technician and a secretary for support. Recent awards include Best Paper Awards at EWSN 2019 and ACM SenSys 2013 and the SSF Future Research Leader Award in 2017. For more, please have a look at our research overview. 

Academic Jobs and Salary in Germany

This position is fully funded. Thus, we are hiring a full time junior researcher. It is paid according to TV-L 13. TV or TVÖD denotes the "Tarifvertrag im Öffentlichen Dienst", i.e,  the salary levels of  German civil service employees. TV-L level 13, in German "Entgeltgruppe 13", is the level that PhD students in Computer Science (and some other high-demand areas) qualify for. The starting salary depends on qualification and other factors such as marital status but can be estimated to a gross salary of about €4000 per month. Working hours are roughly 39 per week and the job includes paid vacation and benefits such as health insurance

PhD Studies in Germany

Ahe PhD students works on his or her subject in consultation with the professor (supervisor) and potentially in collaboration with other PhD students and PostDocs. Next to conducting the research, the PhD student shall publish the results at peer-reviewed conferences, workshops and journals and is expected to produce and defend a thesis or dissertation at the end. PhD studies offer the unique opportunity to deeply dive into a specific topic, devise new approaches and methodologies and to answer questions no one has answered before. With these great opportunities comes a demand for a high degree of personal initiative, self-motivation and responsibility. In Germany, PhD students can take additional courses at the university and attend summer schools to deepen their knowledge in their areas of research, but they commonly do not have to take a specific amount of credit points as in other countries. The duration of a doctorate, i.e., the PhD studies, depends on the students' own progress and other duties such as project work or teaching responsibilities, but one can say that three to five years are typical.

Corona Virus (COVID-19): Exams and Teaching

Situation as of now, 6th of April:

Courses: The courses BSKS, IoT and IT-security will start as planned but in an online manner as long as needed (for now until April 19th 2020). Online teaching starts in the week of 6th of April onwards, i.e., on the regular starting date of the course. Please note, we are trying our very best to make teaching possible. But, it is all a huge experiment. You can expect that there will be hiccups, problems and unforseen challenges etc. Please see here for information on each course. 

Exams: Our research groups' written (re-)exams of the winter term 2019/2020 are postponed / canceled. Thus, there will be no (re-)exam for the Distributed Systems Course on the 26th of March 2020 as orginially scheduled. It is likely, that the exam can be taken at a later point in time, but we are awating details. Similarily, we are still waiting for details about the exams of the summer term 2020. 

We will try to keep this page updated. Please note that the text above is only the research groups' (current) understanding of the situaton. Please always refer to the guidelines of the university here in German and here in English for the official and up-to-date information. Please stay safe and healty!
