Postdoctoral fellow

Laboratory of Protein Metabolism in Development and Aging

Location: Warsaw, a vibrant city with an international academic research environment. International Institute of Molecular and Cell Biology ( - one of the most dynamic and top ranked Polish research institutes.

Job description: Laboratory of Protein Metabolism in Development and Aging is seeking highly motivated and talented Postdoc to join young team investigating the protein homeostasis in development and aging. We use both genetic, molecular and biochemical approaches, primarily in the C. elegans, to study proteolytic networks. Postdoc fellowship is funded in frame of National Science Centre OPUS grant.

Summary: Organismal development or environmental stimuli challenge the homeostatic protein balance (proteostasis) of individual cells, tissues or the entire organism. The ubiquitin proteasome system (UPS) is a key determinant of proteostasis as it regulates the turnover of damaged proteins supporting cellular protein homeostasis and thereby maintains the proteome during stress and aging. Our long-term objective is to understand the mechanistic and developmental aspects of protein degradation pathways defined by combinations of particular ubiquitin ligases (E3). The identification of stress and aging-induced signals that coordinate the interplay between specific E3s will offer intriguingly new mechanistic insights how proteolytic networks are fine-tuned to maintain the cellular proteome and support development and longevity.

• PhD (or be close to completion) in Molecular Biology, Cell Biology, Protein Chemistry, Genetics or a related discipline;
• experience in C. elegans or cell culture is an advantage;
• experience in molecular biology, biochemistry and genomic engineering is an advantage;
• good writing and oral communication skills in English, and competence in scientific writing.
