Call for applications: Marie Skłodowska-Curie Early Stage Researcher (Ph.D. Research Position)

Full-time up to 3 years position


Closing application date: March 1st, 2020

Reference:  NoBIAS ITN


PhD topic: Time-dependent monitoring and mitigation for bias in data-driven AI systems

The Leibniz University Hannover and L3S Research Center, Hannover, Germany invites applications for 1 fully funded PhD student positions in the areas of Machine Learning, Data Mining, Artificial Intelligence (AI) and AI ethics.

The project context: NoBIAS

The position is part of the NoBIAS project ( funded by the European Union Horizon 2020 research & innovation programme under the Marie Sklodowska-Curie Innovative Training Networks (ITN).  NoBIAS aims at developing novel methods for AI-based decision making without bias by taking into account ethical and legal considerations in the design of technical solutions. The core objectives of NoBIAS are to understand legal, social and technical challenges of bias in AI-decision making, to counter them by developing fairness-aware algorithms, to automatically explain AI results, and to document the overall process for data provenance and transparency. The NoBIAS-Artificial Intelligence without Bias network offers in total 15 PhD positions related to AI and bias (see all positions here).

Your tasks

The PhD project “Time-dependent monitoring and mitigation for bias” addresses the discovery and mitigation of bias in time-evolving machine learning models generated from sequential processes and data streams. To this end, data-ageing techniques inspired by the domain of data stream mining and adaptive ML as well as data augmentation techniques for non-stationary data will be investigated.

How you will work:

You will be part of a stimulating and dynamic network of various European top-level universities and other institutions. You will be based at Leibniz University Hannover, Germany. On a regular basis, you will conduct research visits and secondments at several of the NoBIAS partner institutions (both academic and industrial), according to the individual career development plan. You will engage, throughout your PhD, at NoBIAS partner organizations across the EU, in disciplines including computer science, social sciences, and law. You will engage in the NoBIAS research activities and actively collaborate within the consortium. You will actively participate in the training programme offered by the NoBIAS ITN.

You will work independently as well as in local and international teams, with a focus on producing excellent research as well as in learning and acting in real-life contexts of AI creation and deployment.

Your profile

You have a Masters degree in Computer Science, Data Mining, Machine Learning, Artificial Intelligence, or a similar discipline. You have strong data science skills. Skills in learning from sequential data and data streams are a plus. Prior experience with topics with an ethical dimension (fairness/bias/discrimination, privacy,…) is a plus. You care not only about AI, but also about the ethical dimension of informatics, and you are motivated to learning and taking a critical and interdisciplinary approach that values the social sciences while leveraging your computer scientist’s understanding and skills. You work efficiently and reliably, independently as well as in teams. You have very good communication skills and scientific curiosity. Proficiency in English is expected; knowledge of further European languages is of advantage.  You are flexible and prepared to travel and to integrate into the local teams, while keeping a focus on your PhD and on delivering scientific and other project-related output.

We are open to all applicants, but specifically encourage people from traditionally under-represented groups to apply.
