PhD Position in Chemical Biology Targeted Protein Degradation and Kinase Signaling in Cancer

The research group of Natalie Scholes is looking for a highly motivated PhD candidate to join her team. This group works at the intersection of chemical biology systems biology and synthetic biology to study and manipulate cellular signaling networks in cancer. The focus is mainly on kinase signaling pathways and aimed to develop new pharmacological strategies to understand and modify these networks.

A central approach in our work is chemically induced proximity (CIP) - a technique that uses small molecules to bring two proteins together thereby altering their function. This can result in new types of biological activity such as targeted protein degradation catalytic inhibition activation or changes in protein localization.

Building on our experience we are particularly interested in using CIP to degrade proteins enabling us to study and target functions beyond enzymatic activity. Our goal is to understand how proteins and protein complexes function and how we can modulate their function using small molecules.

Currently our main focus is on expanding the potential of such proximity-inducing drugs within oncogenic kinase signaling. Projects that are initiating in our lab are:

• Investigating how mutations in kinases affect cancer-related signaling;

• Using high-content imaging to discover new molecular glue degraders;

• Identifying proximity-based drug targets in the understudied dark proteome.

To study these topics we use a wide range of techniques covering functional genomics including large-scale CRISPR/Cas9 and saturated mutagenesis screens transcriptomics as well as (chemical) proteomics and phenotypic drug screens. We are looking for motivated candidates for a PhD student position in our lab to work with us on these exciting topics and who is interested to learn advanced molecular techniques and unravel the molecular signaling in normal and cancerous cells.

In January 2026 Natalie Scholes will start her own research group at the NKI. She is currently working at CeMM/AITHYRA in Vienna where her postdoctoral work has focused on small molecule inhibitors that can also act as degraders. She is excited to build a team with likeminded people in which they aim to solve important biological questions challenge each other but also help and support each other.

This vacancy is open for applications until November 16th 2025.
