Postdoctoral Research Associate, Peter Gorer Department of Immunobiology

About Us

The laboratory of Dr. Rushad Pavri at King’s College London is inviting applications for a postdoctoral position for a project focused on understanding the molecular mechanisms of antibody somatic hypermutation and its impact on autoimmune disease.

The Pavri group has a long-standing interest and expertise in the molecular mechanisms of antibody maturation and associated genome instability in B lymphocytes. Specifically, we investigate how transcription, chromatin architecture, DNA replication and epigenetic features regulate the key processes of antibody somatic hypermutation and class switch recombination as well as the oncogenic chromosomal translocations arising from these mutagenic pathways. In addition, we study the physiology of germinal centers in murine lymphoid tissues, which is where the antibody maturation reactions occur. The laboratory uses a multi-disciplinary approach including mouse genetics, immunological assays, genetic screening and various genomics tools.

About the role

The project is focused on combining artificial intelligence (AI)-based machine learning and experimental validation to decipher the mechanism of somatic hypermutation in antibody variable regions.

Background: Somatic hypermutation (SHM) of immunoglobulin variable (V) genes generates protective antibodies against pathogens and vaccine antigens. SHM also generates pathological autoantibodies causing autoimmune disease and drives lymphomagenesis by mutating proto-oncogenes. Although mutations occur at preferred DNA motifs, there is substantial variation in mutation frequency between motifs, leading to the hypothesis that there exists a sequence “grammar” regulating motif mutability. Our working hypothesis is that this grammar is dictated by intrinsic DNA features flanking the motifs. Deciphering this grammar could provide important insights guiding the clinical modulation of antibody evolution during infection, vaccination and autoimmunity.

Aim: To decipher the sequence grammar underlying SHM, we will use an AI-based machine learning approach to make predictions about genomic features linked with mutability, followed by experimental testing of these hypotheses in human B cells.

The candidate should have a PhD (or have submitted their thesis) in a relevant area of biological or biomedical sciences. They will be expected to design and conduct experiments independently, have excellent written and verbal communication skills, be highly collaborative, co-supervise students and contribute to laboratory management.

The project involves extensive molecular biology, tissue culture and genomics, hence experience in these areas is highly desirable. Knowledge of immunology, gene regulation and flow cytometry will be an advantage.

The project has a major computational component both for AI-driven modelling and predictions, and for bioinformatics analyses of wet-lab data. This will be performed by an excellent team of computational biologists with whom we have a long-standing collaboration. The candidate will have to work closely with the computational team for data analysis and interpretation.

This is a full-time post (35 hours per week), and you will be offered a fixed term contract until 30/04/2028.
