PhD Position Quantum Physics - Rare-earth Ion single Photon Emitter

Job description

Silicon-based microchips are the essential building block of modern electronic hardware, such as computers and cell phones. Can silicon also play a critical role in building the next generation of the internet - the quantum internet? In order to realize a fully functional and scalable quantum network, we are developing highly coherent single photon emitters using erbium ions operating in the telecom C-band and directly embedded in a solid state crystal, such as silicon. Crucially, we are able to realize high-quality light-matter interfaces and directly enhance the photon emission into an optical channel using photonic crystal cavities. By leveraging different isotopes for long-lived and programmable quantum registers, we are planning on realizing all the critical parts for a quantum network using fully integrated and highly scalable structures.

In order to help us achieve our ambitious goals, we are looking for a talented and motivated person, with strong curiousity of rare-earth ion physics, single-emitters in solid-state systems or experimental AMO physics. The successful candidate will work in a dynamic team environment.

At the Groeblacher Lab we have a vision: we thrive to be an inclusive place where a diverse mix of talented people want to come, to learn, to live their passion and do their best work. We are dedicated to promoting equality, creating a safe environment for everyone, and believe deeply in diversity of race, gender, sexual orientation, religion, ethnicity, national origin, age, socioeconomic background and all the other fascinating characteristics that make us different. We truly think diversity is a strength and working in a diverse environment, and being exposed to a variety of perspectives makes us stronger scientists and better human beings.

PhD Position Optimizing Multi-actor Transport and Logistics Systems

Job description

Transport and logistics systems consist of many players with potentially conflicting objectives that continuously strive to maximize their performance. The competition and collaboration between these players can influence their decision-making, which is something that traditional Mixed Integer Linear Programming (MILP) formulations with a single decision-maker cannot capture. The goal of this PhD is to develop novel methodologies at the intersection of operations research and game theory to address these problems. Applications can go beyond the transport and logistics domain.

Your research will focus on mathematical modelling and algorithm development for planning and operating multi-actor systems, taking into account that the actions of one actor influence the opportunities and performance of others. A central methodological component of the position is the development of scalable optimisation algorithms for large and computationally challenging problem instances. You will formulate mathematical programming models and design solution approaches based on techniques such as column generation, branch-and-price, and Benders decomposition.

You will be expected to:

• develop new game-theoretic/optimization models for multi-actor decision problems;
• design scalable solution methods for large-scale optimisation problems;
• contribute to scientific publications in leading journals in operations research, transportation, and logistics;
• communicate research findings to an interdisciplinary audience.

You will join the Transport and Logistics section of the Department of Engineering Systems and Services

Job requirements

• We are looking for a candidate who meets the following requirements:
• An MSc degree in operations research, econometrics, applied mathematics, computer science, industrial engineering, systems and control, or a closely related discipline.
• A strong background and demonstrated experience in mathematical optimisation, in particular mixed-integer programming.
• Excellent programming skills (e.g., Python, Julia, Java, or C++) and experience with optimization solvers.
• Very good academic writing and communication skills in English.
• An open and collaborative attitude and the ability to work effectively in an interdisciplinary and international research environment.
• Knowledge of game theory, bi-level optimization and decomposition-based solution algorithms are a plus.

Postdoc Sustainability and Responsible Innovation for Climate-Resilient Water Systems

Job description

European water systems face increasing pressures from climate change, urbanization, ageing infrastructure, and stricter environmental requirements. At the same time, new hybrid urban water management approaches combining nature-based solutions and conventional gray infrastructure bring opportunities to improve system performance and adaptability. However, significant uncertainties remain regarding the environmental, economic, and societal implications of these innovations, limiting the ability of technology developers, utilities, planners, and policymakers to make responsible decisions about their development and implementation.

In this position you will investigate hybrid urban water innovations, which combe green and grey water infrastructure, seeking to anticipate the potential societal and environmental impacts associated to them. For that, you will integrate Value Sensitive Design (VSD) and ex-ante sustainability assessment within the Horizon Europe project RESILIENT-FLOWS. Therefore, this position involves two parts: Part a focuses on how stakeholders perceive urban water innovations, identifying how values such as sustainability and resilience, should be integrated in their design and implementation. For this, you are expected to develop and analyze stakeholder engagement activities (e.g. interviews, participatory workshops), and coordinate partners to conduct them across multiple European pilot sites. Part b focuses on an ex-ante Life Cycle Assessment (LCA) approach to assess the environmental impacts of hybrid urban water innovations in selected case studies from the RESILIENT-FLOWS project. Depending on your interests, you may focus more on part a or b above, however the position requires you to engage in both. The results from your research will serve as key inputs to decision-support tools developed within the RESILIENT-FLOWS consortium, enabling utilities, planners, and policymakers to evaluate alternative innovations for climate-resilient urban water management.

Your main responsibilities will include:

• Designing and coordinating stakeholder engagement activities, such as stakeholder interviews and focus groups
• Analyze how values such as resilience and sustainability could be taken into account in technology assessment and decision-making
• Apply ex-ante Life Cycle Assessment methodologies for emerging water infrastructure solutions
• Support project partners on the integration of stakeholder insights and sustainability assessment results into broader assessment and decision-support frameworks
• Publishing research findings in leading international journals and presenting results at scientific conferences
• Contributing to project deliverables and collaborating with academic and non-academic partners across Europe

You will become part of a multi-disciplinary team and collaborate closely with researchers working on nature-based solutions, water treatment technologies, digital twins, amongst others. This position offers a unique opportunity to help shape emerging approaches for integrating sustainability assessment and responsible innovation in the design of future climate-resilient water systems. In this position you will be working closely with researchers, utilities, municipalities, regulators, and technology providers across various European countries.

Job requirements
We are looking for a reseracher who has afinity with quantitative and qualitative methods, and who enjoys questioning assumptions, metrics, and indicators to better understand what a desirable innovation is.

For that, the vacancy's requirements are:

• PhD in Industrial Ecology, Sustainability Sciences, Technology Assessment, or a related field
• Proven experience with Life Cycle Assessment
• Proven experience with qualitative data gathering methods, such as interviewing and focus groups
• Interest in Urban Water Systems and Nature Based Solutions
• Ability to analyze both qualitative and quantitative data
• Excellent communication and scientific writting skills
• Ability to work independently while collaborating in interdisciplinary and international teams
• Excellent command of English

Good to Have

• Experience with ex-ante or prospective Life Cycle Assessment
• Background or experience with Urban Water Systems and Nature Based Solutions
