Bridging the gap between physics and chemistry in early stages of star formation
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.

Photocleavable activity-based acid glucosylceramidase probes
Lysosomal acid glucosylceramidase (GBA1) is a lysosomal enzyme that degrades glucolipids with its main substrate being glucosylceramide (GlcCer). Defects in the GBA1 gene lead to glycosphingolipidosis Gaucher disease (GD), in which the hydrolysis of GlcCer is impaired and therefore, it accumulates in…

Interview met hoogleraar Data Science Aske Plaat over het belang van data science
Ebola heeft niet alleen een hoop dood en verderf gezaaid, maar heeft ook iets moois opgeleverd. Er is veel vooruitgang geboekt op het gebied van ziektebestrijding en -preventie- nota bene door statistici - die kan helpen bij toekomstige virusuitbraken. 'Iedereen die een beetje in het vakgebied van de…

Rijst in plaats van koeien? Veel media-aandacht voor proef in de polder
In de polder bij Oud Ade hebben onderzoekers uit Wageningen en Leiden eind mei zo'n 3.000 rijstplanten geplant. Ze willen testen of rijst een duurzame oplossing kan zijn voor veenlandbeheer in de toekomst: het waterpeil verhogen en toch voedsel produceren. Verschillende media waren geïnteresseerd in…

Data-driven donation strategies: understanding and predicting blood donor deferral
The research in this dissertation aims to optimise blood donation processes in the framework of the Dutch national blood bank Sanquin. The primary health risk for blood donors is iron deficiency, which is evaluated based on donors' hemoglobin and ferritin levels.

Assessing global regionalized impacts of eutrophication on freshwater fish biodiversity
Freshwater biodiversity has been threatened by eutrophication due to excessive nutrients in the environment. Releasing the freshwater species from such pressures requires efforts from industry and manufacturers to avoid emissions to vulnerable and high-risk regions.

Corruption & Integrity in the Netherlands (1945 - present)
Corruption, integrity (or a lack thereof…) and public values are near omnipresent elements in public administration and politics of all times. Cases of corrupt public officials and politicians continuously emerge. Strangely enough, however, it often remains unknown what actually occurred, how something…

The interplay between stars, gas and dust in faint star-forming galaxies
When observing star-forming galaxies, we are not only seeing stellar light, but we also see how this interacts with galactic gas and dust. This thesis contains studies of the stellar, nebular and dust properties of low mass star-forming galaxies.
