The mission of science based business (SBB) connects the domains of science, business, and policy. Scientific research we focus on at Leiden in areas such as artificial intelligence promises to reshape our societies for the better. Translating science into positive societal impact however requires new…

Supramolecular polymers are class of materials that are formed by non-covalent interactions such as hydrogen bonding, π-π interactions, electrostatic interactions and the hydrophobic effect.

In this project innovative technology for photovoltaics cells is developed and analysis of ecological and health related risks are explicitly accounted for.

The living plant collections form the heart of the Hortus botanicus Leiden and serve as a vital resource for scientific research. By studying these collections, researchers can explore biodiversity in a unique way and conduct experiments on living material.

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…

In this research group, led by Dr. Joost Beltman, the aim is to employ mathematical and computational dynamical modelling approaches in order to quantitatively and mechanistically understand the dynamical behaviour and regulation of intracellular networks of genes, proteins and metabolites as well as…

How do museum visitors interpret the authenticity of museum objects? How can we support visitors' meaningful interactions with real objects?

On 11 October, Amanda Pasma defended the thesis 'Re-entry support from prison-based and community-based professionals'. The doctoral research was supervised by Paul Nieuwbeerta, Hanneke Palmen and Esther van Ginneken.

Inverse problems are problems where we want to estimate the values of certain parameters of a system given observations of the system. Such problems occur in several areas of science and engineering. Inverse problems are often ill-posed, which means that the observations of the system do not uniquely…

This thesis describes the use of an activity-based proteomics method to study the endocannabinoid system.

How can teachers be motivated by their students’ data in making stepwise changes to their teaching practices?

Microscopic insight on lipid-based nanomedicine in vivo remains limited to the perception of the knowledge that could be obtained: if we interpret only what we see, then we only believe to know. Although believing to know encapsulates an undefined amount of uncertainty in the exploration of lipid-based…

In the last decades, activity-based protein profiling (ABPP) has emerged as a powerful chemical tool that may aid the ever-challenging drug discovery process.

Glycosidases are important enzymes in the turnover of polysaccharides and glycoconjugates, and are involved in a range of human pathologies including genetic disorders such as Gaucher and Pompe disease, but also in various cancers.

Business Process Model and Notation (BPMN) has become the standard for business processes diagrams.

What are the key issues in conducting LCA of bioenergy systems? What is the environmental sustainability status of second generation bioethanol? How much would the final results of biogenic carbon neutrality assumptions deviate from the true values based on a complete inventory? How to assess the impact…

Access to information is a human right (United Nations, 1948). Information technology, such as search engines and recommender systems, has become the key mediator and facilitator to connect people to information (White, 2016). Conversational artificial intelligence (AI) technology is increasingly being…

Can we establish a new quality control system for herbal medicines that is based on bioactivity rather than a few abundant chemicals?

This research proposal focuses on the investigation of the poetic potentials of negativity through the exploitation of failure in sound based artistic practices - a context that has not been extensively addressed.

A new type of tripodal squaramide-based supramolecular hydrogels is developed and studied.

The work described in this thesis focuses on the development of linear or cyclized peptide probes against protein N-methyltransferases to characterize their specific binding behavior, providing further binding details for inhibitory activity study.

This thesis focuses on the application of lipid-based nanomedicine in drug delivery, including small molecular antitumor drugs and biomacromolecules including mRNA, and evaluates their biological performance.
