Assessing the risks of engineered nanomaterials (ENMs) solely on the basis of experimental assays is time-consuming, resource intensive, and constrained by ethical considerations (such as the principles of the 3Rs of animal testing). The adoption of computational toxicology in this field is a high p…

Zebrafish is an excellent model organism for studying various human diseases. Due to opaqueness of the adult phase, in vivo studies are restricted to early embryonic stages. This raises the need for rapid sensitive and non-invasive in vivo imaging methods to follow developmental processes, not only…

The Systems Pharmacology group is headed by Prof. Piet Hein van der Graaf. Systems Pharmacology is the quantitative analysis of the dynamic interactions between drugs and a biological system to understand the behaviour of the system as a whole, as opposed to the behaviour of its individual constituents;…

Ad IJzerman was elected Highly Cited Researcher in the 2019 Web of Science mapping of research achievements. As defined by the Web of Science team at Thomson Reuters “highly cited researchers are among those who have demonstrated significant and broad influence reflected in their publication of multiple…

Doctors and pharmacists should take greater account of obesity when dosing medicines. The distribution in the body and the breakdown of a medicine can vary considerably in obese patients. This is stated by clinical pharmacologist Catherijne Knibbe in the Annual Review of Pharmacology and Toxicology.

The list of highly Cited Researchers identifies the world’s most influential contemporary researchers across 21 scientific fields. Prof. dr. W. Jiskoot is cited one out of three in the field of Pharmacology & Toxicology in the Netherlands, and as one of four of all categories in Leiden.

Toxys, Leiden University and Leiden University Medical Center have agreed immediately to commercialise and also develop further the ToxProfiler technology invented at the two institutions. ToxProfiler allows for rapid toxicity hazard identification of novel and existing drugs, chemicals, and other substances.…

We are interested in the efficacy and safety of new drugs and novel means to decipher these aspects. Hence, we employ advanced imaging and high-throughput screening techniques next to computational approaches such as chem- and bioinformatics.
