About Faculty of Science

The Faculty of Science is located at the Leiden Bio Science Park. It was founded more than two centuries ago and currently more than 6500 people are working and studying at the eight institutes.


The Faculty of Science is spread over various buildings. The Science Campus consists of the Gorlaeus Building, Gorlaeus Lecture Halls, Gorlaeus Faculty Office, LMUY, Huygens, Oort and Snellius. The buildings Sylvius and Van Steenis are also situated at the Bio Science Park.

The new Gorlaeus Building is in full development. In the future it will house all institutes and departments under one roof. The Gorlaeus Building offers a high-tech environment with state of the art research and education facilities. The first phase of the Gorlaeus Building has been completed and it is in use since 2016. We are currently working on the design for the second phase.

Facts and Figures

The Faculty of Science was established in 1815. Late 2018, it was home to 2282 staff members, of whom about 148 full professors, 155 assistant & associate professors, 173 postdocs, 448 PhD's and 365 guest PhD's. The total number of students at the Faculty of Science is 4471, of whom 2818 bachelor's students and 1653 master's students. Regularly, our staff and students receive grants, prizes, and distinctions. 

We find it important that our students are successful and graduate nominally. The percentage of bachelor's students who graduated nominally in 2015-2016 was 56%. For the master's students, the percentage was 38%. In 2017-2018, 447 students have graduated for their propedeuse within one year, of whom 93 students cum laude and 12 students summa cum laude.


Research and education is being conducted at 8 institutes. The institutes are Mathematical Institute (MI), Leiden Institute of Advanced Computer Science (LIACS), Leiden ObservatoryLeiden Institute of Physics (LION), Leiden Institute of Chemistry (LIC), Leiden Academic Centre for Drug Research (LACDR), Institute of Biology Leiden (IBL), Institute of Environmental Sciences (CML).
