The Basic Science Program (BSP) pursues independent, multidisciplinary research in basic and applied molecular biology, immunology, retrovirology, cancer biology, and human genetics.  Research efforts and support are an integral part of the Center for Cancer Research (CCR) at the Frederick National Laboratory for Cancer Research (FNLCR).


The Flow Cytometry Core (Flow Core) in the Cancer & Inflammation Program (CIP) is a service core which supports the research efforts of the CCR by providing expertise in the field of flow cytometry (using analyzers and sorters) with the goal of gaining a more thorough understanding of the biology of the immune system, cancer, and inflammation processes. The Flow Core provides service to 12-15 CIP laboratories and more than 22 non-CIP laboratories.  Flow core staff provide technical advice on the experimental design of applications, which include immunological phenotyping, cell function assays, and cell cycle analysis.  Work is performed per customer requirements, and no independent research is involved.  

The Flow Cytometry Scientist will be responsible for: 

  • Daily management of the Flow Cytometry Core, to include the supervision and guidance of technical staff members
  • Monitor performance of and maintain high dimensional flow cytometer analyzers and cell sorters
  • Operate high dimensional flow cytometer analyzers and cell sorters
  • Provide scientific expertise to the user community and facilitate the development of cutting edge technologies
  • Interact with Flow Core users and customers, and provide technical and scientific advice, and guidance regarding their experiments, including possible collaborations
  • Train staff and scientific end users on the use of flow cytometry in their research, as well as teach them how to operate and troubleshoot the bench-top analyzer instruments
  • Prepare and deliver lectures, as well as one-on-one training sessions, with customers/users
  • Ensure that protocols are up-to-date, and appropriately adhered to
  • Experience with sterile technique and tissue culture



To be considered for this position, you must minimally meet the knowledge, skills, and abilities listed below:

  • Possession of a Doctoral degree from an accredited college/university according to the Council for Higher Education Accreditation (CHEA) in a field related to biomedical research.  Foreign degrees must be evaluated for US equivalency.   (Additional qualifying experience may be substituted for the required education).
  • In addition to educational requirements, candidates should have had two (2) or more years of competent, innovative research experience beyond doctoral training in a related field of specialty.  Proficiency in developing test or production methods or protocols in an applied area; demonstrated ability to manage a production operation or a segment of a specialized service area.  An individual at this level normally has made contributions by independently producing research work of such originality, soundness, and value as a significant contributor in the field by authoring and co-authoring publications in peer-reviewed scientific journals and by presenting papers before national professional societies.
  • Must be able to obtain and maintain a security clearance


Candidates with these desired skills will be given preferential consideration:

  • Previous work experience in a fluorescence cell sorting
  • Experience with BD flow cytometers and DIVA software

Expected Competencies:

  • Ability to work alone and in a collaborative team environment
  • Requires analytical problem solving abilities
  • Basic understanding of flow cytometry principles and multiparametric instrumentation
