Dr. Monique P.C. Mulder is assistant professor at the Department of Cell and Chemical Biology at LUMC, Leiden (NL). She received her MSc. with honours in Chemical Sciences from Utrecht University in 2007, where she also obtained her PhD degree in Medicinal Chemistry in 2012 under the supervision of Prof. R.M.J. Liskamp. She then moved to the lab of Prof. H. Ovaa at the Netherlands Cancer Institute (NKI). In 2016 she moved to the LUMC, where she currently holds a Junior Group Leader position. Her lab studies enzymatic action in the Ubiquitin Proteasome System including crosstalk between ubiquitin and ubiquitin-like proteins using a combination of chemical synthesis as well as biochemistry and cell biology techniques. The aim of her research is to discover unique components in their respective enzymatic cascades, dysregulated in disease, that could become therapeutic targets in the future.
