  • Demonstrated experience with next-generation sequencing methods:
    • From experimental design to library preparation for various RNA-seq approaches, WGS, and exome sequencing and familiarity sequencing instrumentation (NovaSeq, NextSeq).
    • Experience in single cell genomics would be a plus.
    • Some programming and scripting abilities in languages such as Python to use for genomic data analysis is highly desirable.
  • Solid experience with mammalian cell culture with a focus on primary cell culture with a focus on immunobiology. Some experience with cell separation technologies such as FACS, microscopy (confocal, laser-capture micro dissection) would also be highly desirable.
  • Solid experience with common molecular biology techniques such as RT-PCR, protein work (western, ELISA, immunoprecipitations...) with an ability to optimize new techniques independently.
  • Some experience with rodent handling is preferred (dosing through various route of administration, necropsy…).
  • Demonstrated ability to critically interpret experimental results and independently identify next steps.
  • Excellent oral and written communication skills.
