[ccp4bb] Research Fellow Position - The Hospital for Sick Children Research Institute (Toronto, Canada)

Job description

Dr. Julien’s laboratory at The Hospital for Sick Children Research Institute is looking for a Research/Post-Doctoral Fellow to join our Structural Biology team. The successful candidate will participate in the characterization of a malaria antigen and antibodies against it by using a combination of biochemical, biophysical, immunological and structural techniques. We are looking for a driven and enthusiastic scientist who demonstrates passion and creativity towards the structure/function study of important pathogenic targets and who can thrive in a highly-collaborative setting.


 Roles & Responsibilities

  • Design and optimize constructs for _expression_ in E.coli, insect cells (Sf9) and mammalian cells (HEK 293F);
  • Biophysically characterize purified antigens for their Tm, Tagg and polydipersity with the objective to improve crystallizability;
  • Perform ITC and BLI binding assays between antigens and purified antibodies to determine binding thermodynamics and kinetics;
  • Determine X-ray crystal structures of antigens and antigen-antibody complexes at atomic resolution;
  • Use Electron Microscopy to screen constructs and to determine the molecular structure of antigen-antibody complexes at nanometer resolution.


Desired Skills and Experience

  • Structural Biologist with a PhD in Biochemistry, Immunology, Molecular Biology, or related field;
  • Experience in molecular biology, protein _expression_ in various systems, purification and biophysical characterization (Octet, Optim, ITC, SEC-MALS);
  • Strong knowledge in using structural biology to study malaria antigens, especially in a context of structure-based vaccine design is a plus;
  • Practical experience in using in silico approaches to improve antibody-antigen binding interfaces is a plus;
  • Demonstrated ability to participate in collaborative scientific projects;
  • Organization skills, efficiency and meticulous record keeping.


About Us

Dr. Julien's laboratory is interested in the structure/function study of B cell receptors and their interactions with antigens. A better understanding of the structures of B cell surface molecules will serve towards the rational design of improved vaccine immunogens against a variety of pathogens, including malaria and HIV-1. Dr. Julien’s laboratory is located in The Peter Gilgan Centre for Research and Learning, a new 21-story, 750,000 square-foot facility that incorporates an open-concept design, state-of-the-art research facilities, and collaborative work spaces. 


As a member of the SickKids community, you will become part of a world-renowned organization dedicated to fulfilling a vision of Healthier Children, A Better World. For over 135 years, SickKids has worked hard to make the world a better place for children and their families. SickKids researchers have developed Pablum, discovered the gene for cystic fibrosis and are on the leading edge of research in a wide range of disciplines. Each day, people around the organization are doing meaningful work that directly, and often indirectly, benefits children in Canada and around the world.
