In dit interdisciplinaire onderzoeksprogramma werken onderzoekers uit vijf verschillende disciplines met elkaar samen. Zij stellen zich hieronder (in het Engels) aan u voor.

In this thesis three different topics in number theory are studied.

A modern ship design process is subject to a wide variety of constraints such as safety constraints, regulations, and physical constraints.

Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

Hoe kunnen praktijk en theorie elkaar versterken in de neurowetenschappen? Hoogleraar Birte Forstmann spreekt in haar oratie op 2 oktober over het bouwen van interdisciplinaire bruggen tussen cognitieve neurowetenschap en cognitieve modellen. Haar aanpak kan bijdragen aan hersenonderzoek met minder…

Continuous optimization is never easy: the exact solution is always a luxury demand and the theory of it is not always analytical and elegant.

The lipids in the uppermost layer of the skin, the stratum corneum (SC), play an important role in the skin barrier function. The three main SC lipid classes are ceramides (CER), cholesterol and free fatty acids.

De sectie Cognitieve Psychologie draagt bij aan de 3-jarige bacheloropleiding en verzorgt 2 masterspecialisaties.

Hoe kunnen mensen hun prestaties verbeteren en hun creatieve potentieel benutten? Dat is het onderwerp van het nieuwe Journal of Cognitive Enhancement. Dit interdisciplinaire wetenschappelijke tijdschrift is een initiatief van de Leidse psycholoog Lorenza Colzato. Eerste publicatie maart 2017.

Hoe meer we leren over een (neuro-)psychologische of lichamelijke aandoening en de hieraan gerelateerde gedragsfactoren, hoe beter we deze niet alleen kunnen signaleren, maar ook behandelen. Het is dus belangrijk dat recente inzichten over (neuro-)psychologische problemen en daaraan gerelateerde gedragsfactoren…

The aim of our research program is to better understand the aetiology and course of mood, anxiety and trauma and stressor-related disorders and to test and improve treatments for these disorders.

Metal-based prodrugs based on ruthenium(II) polypyridyl complexes have proven to be very suitable for application in both photodynamic therapy (PDT) and photo-activated chemotherapy (PACT).

Human vocal communication and music perception represent advanced cognitive skills, seemingly innate and universal. These faculties encompass a range of perceptual and cognitive abilities. Cross-species research sheds light on the origins of musicality by investigating whether these traits are shared…

The research described in this thesis combines the latest insights in lysosomal function with lysosome centred cell signalling.

This thesis describes the role of pollution, specifically neonicotinoid insecticides, as an actor of the ongoing biodiversity decline.

Barrier function is the natural role of the skin. The lipid matrix present in the outermost layer of the skin, the stratum corneum is important for this function.

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

It is a common technique in global optimization with expensive black-box functions to learn a surrogate-model of the response function from past evaluations and use it to decide on the location of future evaluations.

This thesis aimed to investigate the impact of exposure dynamics, relative contributions of ENPs(particle) and ENPs(ion), and dosing regimens on the toxicity of ENPs varying in different physico-chemical properties, on the composition and functioning of soil microbial communities.

De Iraakse archeologische site Nimrud werd kort geleden terugveroverd op IS. Maar wat nu te doen met de beschadigde resten? Bleda Düring sprak erover in Trouw.

In de nieuwe videoreeks ‘De wereld van taalwetenschap’ vertellen alumni en wetenschappers over hun passie voor hun vakgebied. Student Aline-Priscillia is vooral benieuwd hoe taal wordt verwerkt in de hersenen.

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…

This work describes several studies into the electroreduction of carbon dioxide (CO2RR), both regarding mechanistical aspects and catalyst stability considerations. Mechanistic insights into carbon-carbon bond formation on a silver catalyst are described in Ch 2, were we find an acetaldehyde-like surface…
