Postdoctoral Position in Molecular Biology

University of Helsinki

Institutions: University of Helsinki – Lengefeld Lab (Viikki Campus) & Khan Lab (Faculty of Medicine)
Unit: Helsinki Institute of Life Science (HiLIFE), Institute of Biotechnology
Location: Helsinki Metropolitan Area, Finland
Start Date: Flexible, positions open immediately
Duration: Postdoctoral positions: 2 years (initially), PhD positions: 4 years (initially)

Description

The laboratories of Dr. Jette Lengefeld (www.lengefeldlab.com) and Dr. Nahid Khan invite applications for two postdoctoral and two PhD student positions in stem cell, metabolism, and aging biology.

The project is NovoNordisk funded and focuses on how rejuvenating the blood system affects systemic metabolic functions during aging. Using mouse models, flow cytometry, RNA/DNA sequencing, proteomics, metabolomics, immunofluorescence microscopy, HSC transplantation, and assays of multiple organs, the goal is to metabolically restore cellular functions to extend healthspan.
