How can you ensure that more experimental drugs reach the finish line? At the moment, only one in twenty cancer drugs that are tested on humans makes it to the market. This is an enormous loss for patients and society. With a grant from the National Growth Fund, Oncode-PACT aims to efficiently select…

The coronavirus has the world in its grip. Finding a cure has never been more important. Unfortunately, the development of new drugs for treatment of the COVID-19 disease caused by the virus and development of a vaccine are complex, lengthy, and above all costly processes. With the help of computer…

The logistics and organisation of LUC’s introduction week 2020 were put under the spotlight this year in light of the restrictions which remain in place with respect to COVID-19.
