A wide range of plant species is essential to our earth because of the different materials and foods these plants provide. But plant diversity has decreased drastically in recent decades. PhD candidate Kaixuan Pan explains what we can do to increase it once again.

More than 5,000 exoplanets have been found over the past couple of decades. These exoplanets show a tremendous diversity, ranging from scorching hot Jupiters, common super-Earths, to widely separated super-Jupiters on the planet/brown dwarf boundary.

Ben Wielstra studies hybrid zones, regions in which distinct populations of organisms meet, mate and produce genetically admixed offspring. In the journal Current Biology, he introduces hybrid zones in an accessible way.

How can we use data to better understand climate change? Can smart algorithms help drive medical breakthroughs? And how do you design technology that contributes to a more sustainable world? If you are curious about how the world works and how to solve complex problems using science, data, and technology,…

How has early development in R. ocellatus been modified as a result of its parasitic embryonic lifestyle?

Ben Wielstra studies balanced lethal systems, in which half of the offspring die before birth. In the journal Current Biology, he explains in an accessible way how such a disadvantage can originate in nature.

This thesis describes the importance of being able to control the selectivity of potential drug candidates.

In this thesis, topics relating to the optimization of high-throughput pipelines used for imaging are discussed. In particular, different levels of implementation, i.e., conceptual, software, and hardware, are discussed and the thesis outlines how advances on each level need to be made to make gains…

Natural history collections provide invaluable sources for researchers with different disciplinary backgrounds, aspiring to study the geographical distribution of flora and fauna across the globe as well as other evolutionary processes.

Learning from nature and utilizing microbial biodiversity to identify and characterize enzymes for degradation and upcycling of plastics and other polymeric materials.

This thesis investigates the application of deep learning techniques in image analysis across various domains, focusing on four main themes: feature extraction, classification, segmentation, and integration, demonstrating the transformative potential of these technologies.

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…

The high velocity tail of the total velocity distribution of stars provides essential insight into fundamental properties of the Galaxy.

LED3 is the combined effort of four excellent institutes of Leiden University. Through joined hands, we are able to give rise to a more effective early drug discovery pipeline. Let us briefly introduce the institutes.

It is a warm day. The sun is shining brightly while biologist Marco Roos makes his way through the bushes towards a peculiar little plant. Insects buzz, birds chirp. In the background rises the LUMC: at the Bio Science Park in Leiden, people and nature come together in a special way.

Man-made sounds in and around the oceans stress marine life and have an impact on marine species and ecosystems by changing the underwater acoustic climate. Hans Slabbekoorn from the Institute of Biology Leiden pleads for technical solutions to mitigate problems of noise pollution. Science review paper…

A global biological study has provided the most direct evidence to date that humans, and specifically cities, are the drivers of evolutionary change on Earth. Leiden University, Naturalis and the Municipality of Leiden worked on and helped fund the study.

This thesis investigates the evolution and fate of gaseous exoplanets, which are continuously shaped by stellar activity across both short and long timescales.

In support of the research and education, the Leiden Institute of Advanced Computer Science (LIACS) has a Research and Education laboratory at its disposal. Within this environment, we can offer machines that go beyond normal office automisation and production.

A P300-based Brain Computer Interface character speller, also known as P300 speller, has been an important communication pathway, under extensive research, for people who lose motor ability, such as patients with Amyotrophic Lateral Sclerosis or spinal-cord injury because a P300 speller allows human-beings…

Reinforcement learning, agents and classification: these are just some of the topics researchers on Artificial Intelligence and Machine Learning discussed at the BNAIC/BeneLearn conference 2020. It was the first time Leiden University hosted the annually held Belgium Netherlands Artificial Intelligence…

Which genes are involved in woodiness and associated traits such as drought tolerance, flowering time, stem elongation, life span, and plant herbivory, and how do these gene regulatory pathways overlap?

Advancing AutoML systems targeting machine learning tasks based on Earth Observation (EO) Datasets.

Biodiversity in the Netherlands is having a tough time. Professor of Natural Capital Koos Biesmeijer combines research with practical advice: from the greening of industrial parks to solutions inspired by hi-tech nature. Inaugural lecture 9 March.

During his visit on 12 April 2016, Dr. Jatna Supriatna was appointed as visiting scholar at the Faculty of Science of the Universiteit Leiden. Dr. Supriatna is a biologist, and is a senior lecturer at Universitas Indonesia’s Department of Biology. His appointment was made in the context of increasing…

On this page you will find a collection of presentations and videos of the Florence Nightingale Colloquia, seminars at the faculty and other event recordings hosted by the Data Science Research Programme.

Cities need to become greener, more biodiverse, and climate-resilient. However, many organisms that are vital for the functioning of urban green spaces and the wellbeing of urban citizens remain largely unknown.

The Hortus botanicus Leiden connects science with the public. Through our research, we explore how people experience and appreciate nature while addressing key societal challenges.
