Electrons in a crystal lattice have properties that may differ from those of a free electron in vacuum.

In some condensed matter systems, such as the surface of a 3D topological insulator, the electrons are effectively massless and we must necessarily use the massless Dirac equation to describe them.

This thesis focuses on data found in the field of computational drug discovery. New insight can be obtained by applying machine learning in various ways and in a variety of domains. Two studies delved into the application of proteochemometrics (PCM), a machine learning technique that can be used to…

The Master Honours Classes & Challenges are part of Leiden’s honours education for master’s students. While the Honours Academy is responsible for the practical organisation, the education is coordinated by teachers of all faculties.

The Leiden Institute of Chemistry (LIC) is to be joined by a further two talented young chemists. Bela Bode and Michele Pavanello have each won a Marie Curie subsidy. Bode will be studying electron transport in photosynthesis and Pavanello will be using computer models to study charge transport in large…

Mathematical and computational analysis of the dynamics of polar transport of the plant hormone auxin.

PBDL favors multidisciplinary research. Depending on the problems under investigation, PBDL establishes collaborations between experts from for example molecular genetics, molecular and electro cell physiology, biochemistry, organic chemistry, analytical mathematics, mathematical statistics and computational…

A selection of recent publications from the Plant BioDynamics Laboratory.

The plant hormone auxin plays a central role in the growth and development of plants. Auxin acts in a concentration dependent manner and polar cell-to-cell transport of this hormone determines its distribution in the tissues of plants. This polar auxin transport is mediated by several families of auxin…

How can the transport of molecules in living cells help to target medicines at exactly the right place?

Although rarely considered by the pharmaceutical industry or clinicians, 24-hour rhythms in physiology are a factor of potential influence on the pharmacokinetics and pharmacodynamics of drugs.

Synthetic cells, also known as artificial cells or protocells, have wide ranging applications from drug delivery vectors to cell models. In biotechnology they can function as micro- or nanoreactors with possible applications in biocatalysis and photocatalysis. Phospholipids are by far the most commonly…

The Green algae Chara as model system for intra and inter cellular transport processes.

In this thesis we study quantum transport phenomena on the nanometer scale, in two classes of materials: topological insulators with induced superconductivity and graphene superlattices.

How do nonmotile microbes leverage communal motility?

PURPOSE: To determine the effect of elasticity on the skin permeation of ketoprofen from surfactant-based vesicular formulations and elastic liposomes.

The Mycenaean civilization of ancient Greek times offers enormous potential for useful information: from innovative construction methods to ways of handling crisis situations as a society. Archaeologist Ann Brysbaert and her team analyse Mycenaean construction processes in the ERC Consolidator project…

Due to the almost complete disappearance of the archive of the Old Dutch West India Company (WIC, 1621-1674) not much is known about the ships and crews of this company. In this project we start the reconstruction of this basic information making use of new digital humanities techniques to extract this…

An estimated 17% of our university's total carbon footprint comes from the thousands of travel movements by our staff, students, visitors, and suppliers. Our aim is to reduce these emissions by a quarter in the coming years.

Tuberculosis is an infectious disease which is spreaded through the air. It is caused by Mycobacterium tuberculosis and it led 1.7 million people to death in 2016. This mortarlity rate is concentrated in developing countries such as Indonesia, Philippines, Pakistan, and South Africa. These numbers make…

The walking club is a ProParte sub-group.

The Plant BioDynamics Lab (PBDL) is a laboratory dedicated to experiments designed to develop and validate quantitative mathematical models of dynamical processes in biology. The principal objective of developing these models is to make quantitative predictions about these processes.

Salicylic acid (SA) is a plant hormone, which is involved in the defense responses to pathogens and to abiotic stress, and in the regulation of plant growth and development.

A major challenge in the formulation of biopharmaceuticals is to overcome their inherent instability during production, storage, transportation, handling and administration. We are studying underlying mechanisms of degradation of biopharmaceuticals (including therapeutic proteins, vaccines and advanced…

In our teaching, we give all our students the opportunity to learn about sustainability themes and issues, where possible ones that tie in with the content of their degree programme.

Leiden University offers its students a wide range of bachelor's, master's and minors that explore sustainability or climate. Here, you find an overview of those programmes in the academic year 2020-2021.

The research aims at achieving a European consensus on a harmonized LCA approach/framework to be applied in E-mobility sector. The research will focus on needs and gaps in current LCA practices in E-mobility and try to provide solutions for them based on the rich knowledge and experience represented…

Plants, are sessile organisms, have developed strategies to adapt to changes in their environment, in part by altering their growth and development.

Atoms and molecules are the basic units of matter. If we keep dividing a bar of gold or a glass of water into smaller parts, at the end we are left with a single gold atom or a water molecule.

On Thursday 16 November 2017 Thomas Leclerc defended his PhD Dissertation ‘A Corrective Approach to Reduce Aircraft Greenhouse Gas Emissions. Contribution to the Study of Interactions between Legal Orders of International Law’. The Supervisors are Professor P. Mendes de Leon and Professor L. Grard.

The guest rooms are located on the top floor of our institute.

A tidal basin is an inland sea which is almost entirely enclosed by land and connected to the open sea by a tidal inlet. Through the tidal inlets interaction takes place between the tidal basin and the open sea.

Possible improvements for the assessment of abiotic depletion in LCA.

On the 30th of September Christine Ketel successfully defended a doctoral thesis and graduated.

No more smelly lorries disposing of building waste or delivering building materials to the centre of Leiden. That’s Leiden University’s ambition for its future renovation or construction projects in the city centre. Electric boats should make the process cleaner and less inconvenient for the people…

Prof. Elizabeth de Lange is concerned with the allocation of resources for the conduct of science towards the goal of best serving the public interest. Also, while she underscores that there is still the need for using animals in drug research, she is concerned about this use, and advocates the use…
