PhD on Continuous Optical Clock

Join Us!
Optical clocks have reached a precision of better than 10-18, which enables them to resolve the relativistic time dilation by only 1cm height difference in the gravitational field of earth. They are useful for searches of physics beyond the standard model, exploration of many-body physics, and societal applications, such as navigation. So far, clocks operate in a pulsed manner, preparing a sample of ultracold atoms and then interrogating that sample. Reaching the ultimate precision needs averaging of 10 thousand samples, taking several hours.

You will join a team building a clock that will overcome this limitation, effectively interrogating the atomic sample continuously. This enables reaching the ultimate precision already after just a few minutes, which is useful for many applications. We want to achieve this by creating a zero-deadtime clock, based on technology that we have developed to achieve continuous Bose-Einstein condensation [Nature 606, 683 (2022)]. We will supply atoms from a continuous ultracold Sr source to four clock interrogation zones that are in one vacuum chamber. Clock interrogation can always be executed in at least one zone, while others are reloaded with atoms, enabling continuous operation.

This is what you will do
With our team, you will finish building our zero-deadtime clock and make it work. This includes integrating complex laser systems, optics, electronics, debugging and data taking, designing and constructing upgrades to the machines, data analysis, literature research, and article writing. You will also take an active role in group activities, such as bachelor and master student education, presentation of your work, and societal outreach.

What we ask of you
We are looking for someone who is excited about pushing novel types of ultracold atom experiments to new reals of AMO physics. You also should have:

• a recent master in experimental ultracold atom or trapped ion physics;
• great team working skills;
• initiative and good time management skills;
• good communication skills in oral and written English.

This is what we offer you
We offer a temporary contract for 38 hours per week for the duration of 4 years (the initial contract will be for a period of 18 months and after satisfactory evaluation it will be extended for a total duration of 4 years). The gross monthly salary, based on 38 hours per week ranges between € 3,204 to € 4,051 (Scale P). This does not include 8% holiday allowance and 8,3% year-end allowance. The UFO profile PhD candidate is applicable. A favourable tax agreement, the ‘30% ruling’, may apply to non-Dutch applicants.

The preferred starting date is to be discussed. This employment should lead to a dissertation (PhD thesis). We will draft an educational plan that includes attendance of courses and (international) meetings. We also expect you to assist in teaching undergraduates and master students. The Collective Labour Agreement of Universities of the Netherlands is applicable.

You will work in this team
The Faculty of Science has a student body of around 8,000, as well as 1,800 members of staff working in education, research or support services. Researchers and students at the Faculty of Science are fascinated by every aspect of how the world works, be it elementary particles, the birth of the universe or the functioning of the brain.

The Institute of Physics (IoP) of the Faculty of Science combines the Van der Waals-Zeeman Institute (WZI), the Institute of Theoretical Physics (ITFA) and the Institute for High Energy Physics (IHEF) and is one of the large research institutes of the Faculty of Science at the University of Amsterdam.

The Van der Waals - Zeeman Institute for Experimental Physics (IoP-WZI) is part of the IoP and home to three research clusters: Quantum Gases & Quantum Information (QG&QI), Quantum Materials (QMat), and Soft Matter (SM). You will work in the Strontium Quantum Gases Group, part of the QG&QI cluster and headed by Prof. Dr. Florian Schreck. We exploit ultracold Sr gases for quantum sensing, the study of many-body physics and for quantum computing. We explore new ways to build sensors, such as continuous optical clocks, and collaborate with industry, startups and users to bring quantum technology to the market. This project is embedded in the Quantum Delta NL Ultracold Atom Quantum Sensing Testbed, which will allow you to contribute to many interesting projects related to clocks, such building a continuous superradiant laser, creating a European optical time and frequency distribution network, or building an industry prototype of an optical clock. Our group is furthermore exploring continuously operating atom interferometers, quantum simulation experiments using Rb-Sr mixtures, single Sr atoms in optical tweezer arrays and improved ways to build optics. Your project will profit from synergy with all these activities. Want to know more about our organisation? Read more about working at the University of Amsterdam.

Postdoc: Mediterranean Community of Practice on Social Innovation & NbS

CARDIMED brings together nine demonstration sites across the Mediterranean — from the Aegean Islands and Central Greece to Sardinia, Catania-Ferla, PACA, Aragón, Alentejo, İzmir, and Nicosia — to scale up nature-based solutions for climate resilience, combining ecological, digital, and socio-economic approaches. Within this consortium, Utrecht University leads the work on the governance and social innovation dimensions of NBS.

This position centres on “Task 3.3 – Establish a Mediterranean NBS Community of Practice as a Social Innovation Network”. Building on insights from earlier translocal social innovation research (TRANSIT, URBANA, ARTS), the postdoc will kickstart and facilitate a translocal Community of Practice (CoP) of NBS social innovation initiatives across the MED region. Rather than building a new network from scratch, the ambition is to connect and weave together existing communities, NGOs, and local entrepreneurs active in and around the CARDIMED DEMO sites into a "community of communities" — a trans-local metanetwork for sharing knowledge and experience on NBS across the Mediterranean.

Concretely, the postdoc will:

• Design and facilitate translocal community interactions, including social innovator dialogues and workshops, combining online, onsite, and hybrid formats to ensure meaningful, face-to-face connection alongside digital reach;
• Co-organise a conference in spring 2027 (probably in Spain), bringing together Cardimed DEMO site communities, researchers, and practitioners to strengthen the Community of Practice and share emerging insights;
• Lead the writing of Deliverable 3.4: Report on the Mediterranean NBS Community of Practice, synthesising the process and outcomes of the Community of Practice for the wider consortium and EU;
• Work closely with the DEMO site partners across Greece, Spain, Italy, France, Portugal, Turkey, and Cyprus to ensure the CoP is genuinely co-created and locally rooted;
• Contribute to the wider dissemination and academic outputs of the CARDIMED project, including a peer-reviewed publication on translocal social innovation networks for NBS.

This is a 17-month, full-time (1.0 FTE) position starting 1 October 2026, running until the end of the CARDIMED project (with Deliverable 3.4 due February 2028). It is a unique opportunity to combine hands-on community organising and network facilitation with rigorous, publishable research on social innovation and environmental governance in a truly Mediterranean-wide setting.

PostDoc to discover and characterize new inhibitory receptors in autoimmunity

We invite highly motived PostDoc with experience in cellular immunology and an interest in academic-industry collaborations to apply.

This is an industry funded PostDoc position set for intensive collaboration between the Inhibitory Receptor Lab and an industrial partner.

Blockade of Inhibitory receptors have revolutionized cancer treatment by unleashing immune responses to cancer. The reverse strategy can potentially be used in autoimmunity to suppress unwanted inflammatory responses by engaging inhibitory receptors on immune cells. The first clinical studies show proof-of-concept, but in addition highlight the need to further improve these therapies.
We previously computationally identified ~400 putative inhibitory receptors encoded in the human genome. In collaboration with an industrial partner, we will short-list putative inhibitory receptors for functional characterization. You will perform cellular assays to detail the expression and function of these candidates using CRISPR/Cas9 in primary human cells. Based on these results, we will make a ‘deep dive’ into a select set of candidates on immune cells of controls and patients with autoimmune diseases. You will be responsible for developing and conducting research at the UMCU, the communication between partners, and reporting to the industrial partner.
