A full-time Research Specialist I/II position is available in the laboratory of Dr. John Jimah at Princeton University. We study the mechanisms of membrane remodeling processes in human cells and malaria parasites. We primarily apply cryo-electron microscopy and tomography to investigate how human and parasite proteins enable cellular processes including endocytosis and the biogenesis of organelles. This position offers an excellent opportunity to contribute to a vibrant research program, and Dr. Jimah is a committed to fostering the career development of all members of the research group.
This position will be within the Molecular Biology Department, an innovative, vibrant, collegial, collaborative, and excellent research environment. Princeton University is in an idyllic town midway between New York City and Philadelphia, with convenient train access to both cities.


The main responsibilities of the research specialist will be the expression and purification of proteins from bacterial, insect, and mammalian expression systems. There is also the opportunity for independent structural studies using cryoEM and/or X-ray crystallography. The research specialist will also have the opportunity to develop their own independent research project.

Attention to detail, precision, good record keeping, organization, time-management and communication skills are essential.
The research specialist will have the opportunity to learn a variety of molecular biology, biochemical/biophysical, and structural biology techniques in a collaborative, vibrant, and supportive environment.

  • Protein expression in bacterial, insect, and mammalian expression systems.
  • Protein purification by affinity and size exclusion chromatography.
  • Maintenance of standard mammalian and insect cell lines for protein expression (for example, HEK 293 F cells).
  • Molecular biology procedures including recombinant DNA technology, cloning protein constructs, polymerase chain reaction, sequencing of DNA, plasmid isolation.
  • Performing well-established biochemical and biophysical assays, including calorimetric enzymatic assays.
  • Keeping up to date with technical skills and scientific literature relevant to the research program and laboratory techniques.




• Bachelor’s degree
• Minimum 1 year of laboratory experience (experience from STEM-related course work is sufficient).
• Dependable; attention to detail; precision; good record keeping, organization, time-management and communication skills are essential.
