PhD Position: Trustworthy Authorization & Compliance

Job description
Within the EU CIPHER project, an experimentation laboratory where essential service providers can assess and strengthen cyber-resilience, your PhD will unite two strands: (i) ethics- and regulation-aware engineering that turns EU frameworks into concrete design requirements, and (ii) just-in-time authorization that enforces real-time, risk-adaptive usage control across organizations. You will design a usage-control pipeline that evaluates every data request against dynamic context, encodes policies as smart contracts on blockchain for transparent, tamper-evident enforcement, and integrates verifiable credentials for cross-border trust. Coupled with a Security Response Manager, the system adapts permissions on the fly. You will also develop compliance-aware guidance and tooling, link authorization to regulatory duties via a checker, and ensure provenance and lifecycle metadata for auditability and continuous monitoring.

The research is hands-on and evaluative. You will deploy your methods in realistic cyber-range scenarios and sectoral use cases (e.g., transport, telecommunications, water), demonstrating end-to-end workflows from risk monitoring to authorization and compliance reporting. Throughout the project, you will collaborate closely with cybersecurity engineers, legal/ethics experts, and industry partners; co-supervise master’s students where appropriate; and publish your results at leading venues in security, distributed systems, and responsible/regulated AI   

Job requirements

• MSc in Computer Science, Computer/Software Engineering, or a closely related field.
• Proven skills in access control/usage control (e.g. ABAC/UCON/RBAC) and Blockchain Hyperledger Fabric, Indy, Besu.
• Solid programming ability (Python, Go, Java, Solidity, TypeScript) and software engineering practices.
• Interest or experience with research collaboration with other researchers and external stakeholders as a team player.
• High motivation and a curious and critical mindset.

Postdoc Researcher on Simulation of Lined-Rock Caverns for Cyclic Hydrogen Storage

Job description
Underground hydrogen storage (UHS) is emerging as a key enabler for balancing renewable energy supply and demand. Yet many regions lack the suitable geology needed for conventional UHS. HyCavern responds to this gap by developing costeffective, safe, and standardized solutions for H2 storage in mined, lined rock caverns (LRC). By tackling key technical, economic, and geological challenges, in this project (HyCavern) we unlock scalable hydrogen infrastructure in areas previously considered unsuitable and increase the lifespan of storage caverns. Among the 15 partners in this unique EU project, at TU Delft we will conduct multiscale simulation for mechanics safety analyses of hydorgen storage in these lined-rock caverns. We will utilize our expertise in elstic/plastic modeling of various porous and non-porous materials to realize the stress and strain developments and evolution in time, during the storage of hydorgen in the caverns. This will scale up the utilization of the LRC as a feasible technology for energy storage.

Our work is integrated within the entire consortium work, in order to maximize the effectiveness of the research outcomes. Our research focus will include

1. Development and extension of an open-source simulator (SafeInCave) with public video-lecture for modelling hydrogen storage in Lined-Rock-Caverns (LRC).
2. Reliable model construction and parameter calibration against laboratory tests and
3. Sensitivity analyses for LRC performance and identification of the key processes in LRC performance and safety.

High level of communication skills and rigorous modeling and simulation analyses are key factors in achieveing our goals successfully.
Currently in our department of Geoscience and Engineering, we are conducting several research on underground hydrogen storage in porous media and salt caverns. This project, i.e., HyCavern, will be the first in the department related to the hydrogen storage in lined-rock caverns.

As a postdoc, you will contribute to the development of the SafeInCave simulator, as highlighted above, so to address the societally challenging energy storage topic by designing a safe operational conditions for utilization of LRC.

Beside the technical work, the postdoc is expected to dessiminate the research effectively through short courses, seminars and conferences, as well as the consortium ggatherings related to the HyCavern project.

The postdoc will be hosted in the Section of Reservoir Engineering of Geoscience and Engineering Department of TU Delft, which is at the Faculty of Civil Engineering and Geosciences. In the Reservoir Engineering Section various experimental, modeling and simulation projects are undergoing on different energy storage applications including hydrogen. For more effective scientific development, we will collaborate with the Engineering Structure Departmet within our Faculty too. We also expect the postdoc to contribute in mentoring activities related to our undergraduate and graduate students, for their thesis projects related to the lined-rock caverns. This also helps the professional career of the posdtco, as well as the content of the research.

Job requirements
With an innate curiosity, we are seeking a creative researcher who can plan, execute, deliver and communicate their research effectively in a diverse groups of talents. The ideal candidate is a team player who thrives working with people in different organisations (academia and industry) with different (technical and non-technical) skill sets. Having a good command of English (both writing and spoken) is crucial. Successful candidate needs to have obtained their PhD in broad Engineering Domain (including but not limited to geoscience and engineering) with special focus on numerical simulation. It is highly advantagous to have background on computational mechanics.
