Jobs

Open PhD positions

Project Description:

The work in this position will be carried out within the SFB “EASE – Everyday Activity Science and Engineering” (funded by the DFG), which is to perform fundamental research to enable robots to do human everyday activities, such as setting a table or loading a dish washer. One strand of research of the CGVR lab in this endeavor is to develop algorithms such that robots can “envision” the outcomes of their tentative plans by simulating the real world around them before they actually follow through with their plan. This requires novel methods for faster-than-realtime physically-based simulation and the development of predicates in order to evaluate the outcomes. In another strand, we will deal specifically with the challenge of grasping. Here, the task is to develop novel methods such that a human user can grasp virtual objects using a virtual hand with high simulation fidelity and high dexterity. The goal is to allow humans to interact with virtual objects just like in real live, and to study their grasping behaviors under a large variety of scenarios and parameters. The tasks will also comprise a small amount of help with teaching in the computer science program (e.g., as teaching assistant). .

About us:

The position offers great opportunities for collaboration with other members of both the computer graphics group and other groups. This job provides a vibrant research environment where a broad range of activities related to space exploration and virtual reality are being pursued. The successful candidate will be working with a dynamic, friendly, and helpful team of computer graphics researchers. Our research group is part of the school of computer science at University of Bremen.

Qualifications:

Candidates should have an excellent Master’s degree or equivalent in computer science, or related disciplines such as mathematics, physics, etc. Required skills are solid experience in C++ software development, and a good command of English (reading/writing/speaking). Ideally, you have specialized in real-time computer graphics or physically-based simulation, you are capable of effectively applying mathematical methods, and you have good knowledge in GPGPU programming. In addition, the successful candidate will be highly self-motivated, passionate about their work, and have good ability to work both independently as well as in a team in a multidisciplinary environment. Speaking German, at least for conversation, is required.

Conditions of employment:

For the time being, the position is available until mid 2021 (under the condition of job release), with the aim of extension.

As the University of Bremen intends to increase the proportion of female employees in science, women are particularly encouraged to apply. In case of equal personal aptitudes and qualification, disabled persons will be given priority. Applicants with a migration background are welcome.

Open Position with the Computer Graphics and Virtual Reality Group Bremen

PhD research position (full-time)
with the Computer Graphics and Virtual Reality Group
at the University of Bremen, Germany,
to be filled as soon as possible

Project: Intra-Operative Information, What Surgeons Need When They Need it
Salary is according to the German Federal pay scale (TV-L 13, gross salary approx.
EUR 40,000 p.a., supported in part by the DFG).

Project Description:

The tasks in this position involve development and implementation of novel methods and algorithms in the fields of computer graphics and virtual reality. The envisioned applications of the work will be in at least two exciting areas, namely in the operating room during surgery, and in CAD for assembly simulation, path planning, and virtual factories. In both areas (and many others), the real-time (or even more-than-realtime) simulation of the behaviour of geometries (e.g., organs or automotive parts) is paramount. In addition, the interaction with such objects in non-conventional settings (e.g., the operating room) requires novel, extremely efficient interaction metaphors.
More specifically, the research will focus on physically-based, mechanical simulation of deformable human organs (e.g., the brain or the liver), the simulation of rigid parts (e.g., automotive parts in an assembly line), and geometric algorithms and data structures for efficient proximity and intersection computations. This will require a good understanding of physically-based simulation algorithms, 3D computer graphics in general, and, possibly, interaction metaphors with 3D environments.

About us:

The position offers great opportunities for collaboration with other members of the project, such as the group for cognitive systems and the group for digital media, both at University of Bremen. In addition, collaborations will be done with the Fraunhofer Institute for Medical Visualization (Mevis) and several hospitals. Furthermore, the successful applicant will get the opportunity to collaborate with CAD software companies.
This project provides a vibrant research environment where a broad range of activities related to medical IT systems, virtual reality, and CAD software are being pursued. The successful candidate will be working with a dynamic, friendly, and helpful team of computer graphics researchers. Our research group is part of the school of computer science at University of Bremen, which is a mid-sized university with about 20,000 students, a lot of them international ones, offering a broad range of fringe benefits such as sports facilities, cultural activities, and daycare.

Qualifications:

Candidates should have an excellent Master’s degree or equivalent in computer science or mathematics, or in a related discipline such as physics, etc. Ideally, you have specialized in real-time computer graphics or physically-based simulation, and you have good knowledge about applied mathematical methods and parallel programming. Required skills are solid experience in C++ software development, and a good command of English (reading/writing/speaking). In addition, the successful candidate will be highly self-motivated, passionate about their work, and have good ability to work both independently as well as in a team in a multidisciplinary environment.

Conditions of employment:

The position is available for a period of 3 years (under the condition of job release).
