PhD position: Develop Hybrid Machine Learning for Global Soil Mapping

Predicting ecosystem dynamics under global change requires accurate and consistent soil information at global scale. Current global soil maps are derived using empirical machine learning that often ignores known soil processes, resulting in inconsistencies across soil properties and underperformance in data-scarce regions.

This PhD project will develop next-generation machine learning methods for geospatial prediction by integrating process knowledge into modern AI tools. The research offers the opportunity to explore neural network architectures, tabular transformers or Bayes methods to include process-information into machine learning and to develop new geoAI approaches for spatiotemporal mapping usable across domains.

The project is embedded in the Computational Geography group at the Department of Physical Geography, where you will work with researchers in environmental geo-spatial AI method development, soil modelling and spatial statistics.

PhD Positions in Experimental Physics Research on Magnetic Domain Wall Qubits

Job description
The Kouwenhoven Lab is seeking PhDs researcher to join our team in developing a new type of qubit based on Majorana bound states in Kitaev chains.

This project will develop Majorana qubits in longer Kitaev chains, thereby reaching topological protections. We foresee chains up to 5 sites in qubit geometry. We will study the different noise sources that can dephase the qubit and how to protect against these disturbances.

We will explore new gate operations including fusion and braiding which are special qubit operations unique for Majorana bound states. We will study the effect of improved protection on these operations when making the chains longer. In addition, we will develop 2-qubit gate operations, creating entanglement between different pairs of Majoranas.

This PhDs position will also work in close collaboration with a partner group specialized in 2D materials (Goswami group) and a theory group (Wimmer group) for numerical simulations.

We welcome applications from motivated and passionate experimentalists with a background in low-temperature electrical transport, qubits and a strong interest in both academic research and technological applications. A doctoral degree in a relevant field, or the expectation of obtaining one soon, is required.

You will join a diverse and inclusive team at QuTech, located in the heart of the TU Delft campus. Our state-of-the-art research facilities provide a world-class environment for quantum and nanoscale research, offering exceptional opportunities for innovation and collaboration.

Requirements

• Master Degree in Physics, Applied Physics, Electrical Engineering, or a closely related field.
• Strong background in quantum science and solid-state physics.
• Independence and self-drive, with the ability to identify interesting questions and interpret measurement outcomes.
• Excellent Collaboration and communication skills
• Optional but highly appreciated: background in experimental research in spin qubits, magnetic materials, spintronics.

We strongly encourage candidates from all backgrounds and identities to apply. We believe diverse perspectives drive innovation and excellence.

PhD Position Hydrogen-based Novel Flow Battery Technology

Job description

Energy storage is an indispensable factor for bridging the electricity consumption with the intermittent renewable energy supply. With increasing supply of renewable electricity in our energy mix, and electrification across industrial, transport, commercial, and residential sectors strains existing grid infrastructure, electricity storage is required to prevent congestion and transmission bottlenecks. This energy storage is required at a broad range of timescales. While technology is available for the short to medium timescales, very little technology is available to store electricity efficiently to cover durations of 25+ hours.

In that light, we started the collaborative research project REDOX BLEND, performed at seven Dutch universities and knowledge institutes (TU Delft, RUG, UTwente, TU/Eindhoven, U Nijmegen, DIFFER, TNO) to develop next generation batteries for ultra-long-duration energy storage.

This project will focus on the development of inorganic, hydrogen-based flow batteries, for high power density and energy density. Among these is the hydrogen-iodine flow battery. This battery type has fast kinetics and recent work demonstrated that an electrolyte with high pH and co-solvent can achieve high iodine solubility and high open circuit voltage. However, this battery type is in early stage of development. Further analysis is required, including studying the configuration of such alkaline H2-I2 battery and longer- term stability. Results will be compared and merged with developments in other flow battery chemistries, developed at other universities and industrial partners (Aquabattery, Elestor, Ore Energy) in this project.

We're looking for a candidate with an excellent performance in BSc/MSc studies, with knowledge about electrochemistry and experience in performing laboratory experiments. For this vacancy, we're looking for a candidate with strong engineering skills (rather than materials science or fundamental electrochemistry), to demonstrate this technology at stack level. The candidate should also have a pro-active mindset and good skills to collaborate in with partners in the project and allow to evaluate this technology for ultra-long energy storage from multiple angles.

Job requirements
We’re looking for a candidate with:

• A MSc degree, in chemical engineering, mechanical engineering, applied chemistry, applied physics or similar
• Experience in working with energy technology
• Proven experimental skills
• Knowledge in engineering or process technology
• An excellent grade list
• Pro-active and creative mind-set
• Fluent in English. Speaking Dutch is a plus
• Starting date in Q4 2026

TU Delft creates equal opportunities and encourages women to apply.

This PhD position offers:

• Challenging job in a highly innovative technology field
• Embedding in an enthusiastic team of engineers and researchers
• Collaboration with industrial partners
• A position with funding for 4 years
