ACPA Professor of Auditory Culture and Music Philosophy Marcel Cobussen and ACPA PhD Supervisor Vincent Meelberg are, together with composer and Simon Fraser University Professor Barry Truax, editors of the recently published Routledge Companion to Sounding Art.

After the Summerbreak the Honours Class entitled The Sounding City will be offered, in collaboration with ACPA and the Science Faculty. The class instructors will be Prof. Marcel Cobussen and Edwin van der Heide. They state that one of their main objectives for this course is

Do the sounds that surround you as you cycle through the city sometimes annoy you? Don’t worry, because we can actively change the situation, says sound expert Edwin van der Heide. Students in his Honours Class are actively shaping the sound of the city.

Wiskundemeisjes Jeanine Daems and Ionica Smeets will be on television. From Thursday, November 15th on, on Nederland 2, from 9.30-9.45 AM, they will be part of a school-television series entitled `Math for Second Phase'.

PhD defence

An essential protein that regulates our heart beat turns out to be important for cancer cells as well. The discovery might open novel treatment strategies for fighting metastasis. Publication in Science Signaling on April 4th.

Erik Danen is looking at how to inhibit tumours that do not respond well to medicine – and he is making some headway. The Professor of Cancer Drug Target Discovery studies the interaction between tumour cells and their surroundings. Inaugural lecture on Friday 10 May.

What is the Electronics Department?

The STRINGS project is mapping development pathways for science, technology and innovation that best address the UN Sustainable Development Goals. A consortium of seven universities led by Tommaso Ciarli at SPRU at the University of Sussex and the UNDP (United Nations Development Programme) have worked…

A next, general pharmacological problem to be tackled is how drug-target binding kinetics in vivo, affects target occupancy as an important indicator of the time-course of drug effects.

The discovery of new medicines is a tedious and lengthy process. On average, over 10,000 molecules need to be studied for one to become a drug and reach the patient. Part of that process are the very costly clinical trials in humans, and candidate drugs often fail due to side effects or lack of efficacy.…

The group of Dr. Roxanne Kieltyka designs and synthesizes molecules that self-assemble into polymeric materials using specific non-covalent interactions. These substrates can be used for numerous applications in medicine ranging from disease detection to cell delivery depending on the (bio)molecular…

Learning analytics tracks students’ online learning activities in order to support their learning. But what if most of their learning takes place offline, out of sight of digital eyes?

The Open Science Lab bundles expertise on Open Science at CWTS and contributes to and studies the transition towards Open Science at CWTS, Leiden University, and beyond. It serves as a knowledge broker, facilitator, and platform for learning and exchange.

MRFM combines the principles of magnetic resonance and atomic force microscopy.

Physicists at the Leiden Institute of Physics (LION) conduct fundamental research into physical phenomena. They are inspired by curiosity and the desire to know more about the world in which we live. This research has always paved the way for new practical applications. These are something that the…

Sophia aims to create equal opportunities and promote a better working climate for female academic staff at Leiden University.

The Collective Experience of Empathic Data Systems (CEEDs) consortium developed novel integrated technologies that support experiencing, analysing and understanding of very large datasets.

Data science is now growing fast in many places, but scholars at Leiden University have been developing data science techniques for a long time already. Thanks to their broad-based expertise, Leiden statisticians are currently combining the achievements in statistics with the latest methods of statistical…

We study the structure, dynamics and physics of complex networks emerging from the intricate interconnectedness of the constituents of large systems.

How do protein modifications work together to repair DNA, and what can we learn about these interactions to better understand disease?

LION offers a PhD program in which candidates carry out independent research on a specific topic, culminating in a PhD thesis.

Microbes influence and respond to other organisms. This theme explores the dynamic relationships within plant and animal microbiomes, and the immune responses that govern host defense. Using model systems such as zebrafish, insects, and plants, we investigate fundamental processes and engineer microbes…

The mission of the Plant Sciences cluster is to contribute to the sustainable production of high-quality crops, flowers and high-value bio-based products, and to contribute to the maintenance and restoration of biodiversity in natural ecosystems. This is realised by generating fundamental knowledge…

Two PhD defences on 9 June by behavioural biologist Errol Neo and underwater acousticianan Özkan Sertlek relate to measuring noise in the North Sea and the harm this noise can do to aquatic animals and their surroundings. Little is known about how harmful human noise can be to aquatic animals.

Hans Slabbekoorn is specialised in animal sounds. On 1 July, he was appointed professor of Acoustic ecology and behaviour. A great honour, according to the new professor. ‘This job never gets boring, whether I am investigating the urban jungle or marine noise.’

Underwater noise from seismic surveys affects the behaviour of Atlantic cod. These are the results of research by Leiden biologists in collaboration with colleagues from Belgium. During such surveys the fish are less active than usual and their circadian rhythm is disrupted; soon after exposure they…
