Oscar Fernandez-Capetillo Group

The Fernández-Capetillo laboratory focuses on the use of cell-based phenotypic screens for the development of new medicines. Neglected until rather recently, due to a focus on target-oriented drug development, phenotypic screens have yielded some of the most important medical advances to our societies. With the help of automatized microscopes, the laboratory designs phenotypic screens that aim to mimic a disease condition. The research mostly focuses on diseases that are largely neglected by the industry, or in the repositioning of current medically approved drugs for their use in other diseases.

Research interests

Our recently started laboratory at Karolinska Institutet focuses on the implementation of cell-based phenotypic screens oriented to the discovery and development of novel molecules to improve the efficiency of various diseases. At present, our interests are spread among a variety of topics, such as the discovery of new medicines for amyotrophic lateral sclerosis (ALS), the search for chemical modulators of the immune response, or the discovery of molecules that can regulate the levels of RNA and protein production in cells.

The lab is looking for talented and highly motivated postdoctoral fellows. We seek candidates that have a strong expertise in molecular and cell biology. The person should have deep knowledge in cancer biology or ALS research. Preference will be given to applicants with skills in high-content imaging, automated image processing and gene knockout (CRISPR/Cas9) strategies. The successful candidate should have a strong publication record. Complete fluency in both written and spoken English is a request. The candidate´s personal skills will be highly valued.

Please contact Per Moberg at per.moberg@ki.se directly if you are interested. Postdocs are asked to send a motivation letter and their CV.
