An exciting post-doctoral research opportunity is available in the BioMedicine Design Department at Pfizer, Andover, MA, to participate in the interdisciplinary efforts in support of preclinical-to-clinical dose and efficacy translation for innovative LNP-mRNA therapies. In this role, post-doctoral fellow will be uniquely positioned to lead interdisciplinary investigations of in-vitro-in-vivo correlation (IVIVC) for LNP-mRNA programs, using physiologically-relevant cellular systems, and applying cutting edge cytometry and proteomics techniques, as well as computational modeling approaches. The research findings are anticipated to directly impact the development of future LNP-mRNA therapies.

We are seeking an enthusiastic scientist who is interested in interdisciplinary training and passionate about bringing new medicines to people. The successful candidate will apply their research experience, innovative thinking and knowledge of biological systems, to establish methodologies for the comparison of LNP-mRNA uptake, intracellular trafficking, and mRNA expression in ex vivo cellular models generated from different types of tissues and originating from humans and pre-clinical species and be directly involved in translational modeling activities for determining IVIVC.

The post-doctoral fellow will be immersed in a dynamic biopharma R&D environment, closely working with, learning from, and influencing fellow scientists with diverse technical expertise, ranging from multi-parameter flow- and quantitative imaging- cytometry to high resolution mass-spectrometry and translational modeling. The candidate will gain experience in early drug development, LNP and RNA therapies, and generate high-impact publications.

This post-doctoral position requires experience in establishing and optimizing cell-based systems, and, ideally, knowledge of the principles of flow-cytometry or good understanding of quantitative imaging approaches, or proteomics techniques. Background in computational biology is a plus. A great candidate may not bring all these prior experiences, however, should come with a strong background in cell biology and a drive to acquire knowledge and develop complex methodologies.

  • Lead conception of the approach, design and execution; perform experiments, analyze and critically interpret data, communicate results back to mentors
  • Identify and employ strategies for establishing tissue- and species- specific cellular models
  • Develop and apply approaches for the quantitative read-outs of LNP-mRNA interactions with cells
  • Proactively seek new scientific insight with the goal of refining scientific hypothesis and advancing investigations by conducting review of published literature and state-of-the-art research on the topics pertinent to the project and implement learnings in advancing the investigations
  • Proactively collaborate and pursue guidance from colleagues and advisors to timely achieve project milestones and program goals
  • Provide periodic progress reports; effectively communicate findings through presentations at internal and external venues; publications at top-tier scientific journals


  • Recent Ph.D. in cell biology, bioengineering, biochemistry, or related disciplines is required
  • Expertise in development, optimization and implementation of cell-based assays for functional readouts

  • Demonstrated experience in employing flow-cytometry for cell characterization
  • Familiarity with quantitative image analysis techniques
  • Knowledge of mass-spectrometry and/or other proteomics techniques for the analysis of protein expression or protein-protein interactions in cells
  • Experience with RNA or LNP biology
  • Peer-reviewed publications


As appropriate for this lab-based role

  • Lab based position requirements to perform laboratory related activities
  • Occasional travel to Cambridge (Kendall Square) might be needed, depending on project requirements

Sunshine Act

Pfizer reports payments and other transfers of value to health care providers as required by federal and state transparency laws and implementing regulations. These laws and regulations require Pfizer to provide government agencies with information such as a health care provider's name, address and the type of payments or other value received, generally for public disclosure. Subject to further legal review and statutory or regulatory clarification, which Pfizer intends to pursue, reimbursement of recruiting expenses for licensed physicians may constitute a reportable transfer of value under the federal transparency law commonly known as the Sunshine Act. Therefore, if you are a licensed physician who incurs recruiting expenses as a result of interviewing with Pfizer that we pay or reimburse, your name, address and the amount of payments made currently will be reported to the government. If you have questions regarding this matter, please do not hesitate to contact your Talent Acquisition representative.
