This thesis aims to improve the detection from ultra-weak single emitter by enhancing their emission properties with plasmonic nanostructures. We exploit the wet-chemically synthesized single crystalline gold nanorods (GNRs) as our basic frameworks in the whole studies, simply because of their unique…

In this PhD-thesis several new and existing data science application are described that are particularly focused on applications for tax administrations.

My ERC Starting Grant, funded with €1.5 million for 5 years as part of the Horizon 2020 research and innovation program, is focused on building the early warning system WARN-D to reliably forecast depression in young adults before it occurs. Why depression, and why prediction?

Digital technology is changing academia and society at lightning speed. LIACS is in the midst of this with groundbreaking research into data processing and artificial intelligence (AI). It conducts a unique combination of fundamental and applied research into major issues facing academia and society…

By detecting the tiny forces between a micrometer sized magnet and the spins of hydrogen nuclei, we can do MRI with a volume resolution that is approximately 12 orders of magnitude better than a conventional MRI.

In this thesis chemical and physical processes in the ice mantles on interstellar dust grains are studied.

This thesis contributes to studying primordial cosmology theories and their detectability in future observations.

This online advanced summer programme of Leiden University and ICCT focuses on the field of preventing, detecting and responding to violent extremism and gives insight in the opportunities and challenges of various approaches.

I have studied the hot, diffuse gas around and between galaxies. Specifically, I have used the EAGLE numerical simulations of galaxy formation to predict the properties of this gas, and I have used those properties to predict specific observables: soft X-ray absorption and emission lines.

A difficulty of studies on chemical kinetics are the reaction time scales and detection of their intermediates.

Exploring the largest structures in the universe by looking at the tiniest particles? Lydia Stofanova, PhD candidate at Leiden Observatory and SRON Netherlands Institute for Space Research, dives into this intricate connection. In her PhD research, she explored how elements like oxygen influence the…

Single-Molecule Microscopy (SMM) techniques constitute a group of powerful imaging tools that enable researchers to study the dynamic behavior of individual molecules.

Classical mathematical models treat space and time as a continuum, while it is sometimes more useful to regard it as granular. Hupkes is studying what this means for a number of important patterns that are often found in computer calculations and in nature.

The arrival of Columbus to the Caribbean in 1492 marked a milestone in world history. In both the European and the indigenous world, a set of economic, political and hierarchical networks and relations were defined, structured and changed. These changes affected the indigenous population at different…

In STAYAHEAD data-intensive approaches are being developed to ”decode the human immunome” with a focus on a global vaccine strategy. They have developed a rapid mass spectrometric test to analyse in real-time large numbers of variants of SARS-CoV-2 and the host immune response, and use these data to…

Research at the SBC group is comprised of the following research themes:

Understanding the formation and evolution of planetary systems is one of the most fundamental challenges in astronomy. To directly image and study young exoplanets and the circumstellar disks they form from, dedicated high-contrast imaging instruments are built.

Metal complexes and 2D materials like graphene were combined to produce structures that can function as sensors.

A dense region of a gaseous and dusty cloud collapses to form a protostar surrounded by a disk and an envelope. This thesis uses both observations and models to study physical and chemical conditions of these protostellar systems which are likely where planets start to form.

Until the 1990s, the only known planets were those in our Solar System. Three decades later, several thousand exoplanets have been discovered orbiting stars other than the Sun, and substantial efforts have been made to explore these strange new worlds through spectroscopic analyses of their atmosphe…
