De komst van de smartphone heeft onze levens veranderd en beïnvloed: we lijken niet meer zonder te kunnen. Het is inmiddels het meest gebruikte apparaat om online te gaan, maar toch lijkt er de afgelopen jaren een behoefte te zijn ontstaan om juist niet online te zijn. Pepita Hesselberth, universitair…

Over the past years it has been discovered that the population of extra-solar planets is large and diverse.

Forming at the nodes of the Cosmic Web and growing hierarchically via mass accretion, galaxy clusters are the largest virialized halos in our universe, composed of dark matter (DM; ≥85%), ionized hot plasma in the intracluster medium (ICM; ≥10-15%), and galaxies (≥1-5%).

In this thesis, we developed new ways to use a technique called electroextraction (EE) to extract charged molecules from one liquid into another using an electric field.

Explaining treatment response variability between and within patients can support treatment and dosing optimization, to improve treatment of individual patients.

The ideas underlying this thesis are that lipidomics may improve the diagnosis of liver metabolic diseases, and can provide further insights into the underlying pathophysiology of these diseases.

Teaching the Future: AI-Enhanced Education for Student Engagement and Ethical Learning.

The challenge of achieving fast quantification in metabolomics is the presence of severe matrix effects during the MS analysis of complex samples.

Metabolomics has the potential to play a pivotal role in understanding disease onset and progression, and ultimately personalized treatments. One of its major challenges is its large-scale implementation, which is necessary to deal with the high variability of the metabolome. In this work we have developed…

Metabolomics is a powerful tool that can provide a comprehensive insight into the complexity of human biology and the pathophysiology of diseases. By analyzing the metabolome, which refers to the complete set of small (endogenous) molecules (with a mass <1500 Da) present within a given biological system,…

Athletes always strive for the top. How can data scientists assist them in improving their performance? During the seminar Data Science and Sports, the possibilities and challenges of collaboration between these two worlds were discussed.

The LIACS Media Lab has received a research grant from the worldwide leading graphics hardware company NVIDIA. The grant exists of newly developed hardware utilizing thousands of processors. LIACS researchers will use it to investigate deep learning in understanding imagery from sources such as MRI…

Ter nagedachtenis aan Andrea Evers, hoogleraar Gezondheidspsychologie, is het Prof. Andrea Evers Fonds voor Gezondheid, Gedrag en Samenleving opgericht. Met dit fonds willen we haar diepste wens eer aan doen: het voortzetten van onderzoek dat aantoonbaar bijdraagt aan gezondheid, welzijn en een veerkrachtige…

Met levenscyclusanalyse (LCA) ontdek je de complete milieu-impact van spullen of productieprocessen. Door Europese regels wordt dat steeds belangrijker.

Het Data Science Onderzoeksprogramma (DSO) combineert Leidse promotieonderzoeken uit allerlei disciplines met data science. Het programma loopt nu ruim twee jaar, en levert verrassende eerste resultaten op. Hieronder vertellen een aantal promovendi over hun ervaringen en hun onderzoek.

Als psycholoog én piloot is Bert Busscher geïnteresseerd in het fenomeen vliegangst. Busscher ontdekte dat aan de hartslag van mensen tijdens een therapeutische vlucht is af te lezen hoeveel last zij nog van hun vliegangst hebben. De hartslag na de vlucht voorspelt zelfs of de vliegangst op lange termijn…

In 2067 allemaal online naar de psycholoog? Een stoomcursus tijdreizen of juist terug in de tijd met Vincent van Gogh langs de hallucineermeetlat? Onder psychologen zijn Winnie Gebhardt, Andrea Evers en Jan Dirk Blom van de partij in de Nacht van Kunst & Kennis.

Samen met wetenschappers van over de hele wereld streeft de ENIGMA-Anxiety Werkgroep ernaar om meer inzicht te krijgen in de neurobiologische karakteristieken van angststoornissen.

The study of orchid flowers, fruits, and inflorescences is crucial due to the remarkable diversity of orchid species and their unique adaptations to pollinators and seed dispersers. However, our understanding of the evolution and development of these organs within the orchid family remains limited.

This dissertation explores how Large Language Models (LLMs) can effectively and responsibly contribute to complex decision-making processes. By combining AI and human intelligence, Hybrid Intelligence (HI) emerges, allowing the strengths of both humans and machines to be utilized.

We developed the bitterling as a unique, well-studied model organism in the area of the evolutionary ecology of brood parasitism. The bitterling-mussel relationship, interspecific mussel host preference, and mussel gill structure are studied in detail, to help understand the developmental adaptation…
