Ze studeerde biologie in Leiden en ging nooit meer weg. En nu is hoogleraar Immunobiologie Annemarie Meijer de nieuwe vertrouwenspersoon voor promovendi. Een taak die haar perfect past: ze heeft veel ervaring in de onderzoekswereld én begeleidde al tientallen promovendi. In een interview vertelt ze…

Data theory research on the analysis on the multidimensional data

Standaard schooltesten als de CITO-toets laten vooral zien wat kinderen al goed kunnen. Dynamische testen geven juist inzicht in hun potentieel om te leren, ontdekte Mirjam de Vreeze in haar promotieonderzoek. Vooral bij kinderen met leerproblemen als dyslexie of faalangst biedt dat perspectief.

What is the population size/structure and distribution of tiger and leopard inside the Bardia National Park (BNP) compared with the population outside? What is the movement and home range and conflict pattern in time and space of tigers and leopards inside the BNP compared with outside? What constitutes…

Aim: To develop and enable application of a practical, flexible, user-friendly platform to provide the scientific community with a tool to generate land surface products and its associated uncertainties and exploit these for data-intensive science.

In September 2023 the new minor Sustainability, Climate Change and Food starts. This minor critically examines the complexities of food sustainability through ecological, socio-economic, political, and cultural systems.

Decarbonizing the building stock is critical for realizing the climate-neutral target for the Netherlands.

This monograph focuses on clustering of objects in high-dimensional data, given the restriction that the objects do not cluster on all the attributes, not even on a single subset of attributes, but often on different subsets of attributes in the data.

Improvements of weak gravitational lensing shape measurements are presented and some used for data analysis.

Materials balances have been used in the recent past for the analysis of substance oriented environmental problems and the formulation of measures for environmental policy. In this study an integrated tool, based on the materials balance principle, has been developed for the analysis of both environmental…

Has the industrial sector in China effectively been decarbonizing in recent years, across different regions and subsectors, and is it plausible that it will reduce its CO2 emissions in conformity with national and internationally pledged emission goals?

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

The deeper understanding of an organism's pathology is important for developing treatments. Over centuries of systematic research, clinical researchers have demonstrated that the more information they acquire about the cellular properties and their organisation in the tissue, the better they can understand…

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

Gold nanorods are biocompatible nanoparticles that present an excellent two-photon signal that can be used to get high spatial resolution inside living cells. Gold nanorods are photostable and therefore can be followed inside cells for long time, with possible applications as trackers in live cells.

The skin is our natural barrier and lipids are a key part of this barrier. In the outer skin layer, the stratum corneum (SC), lipids form a densely organized structure dependent on the composition of these lipids.
