We are interested in delivering mRNAs of interest to express proteins which drive cellular reprogramming. Specifically, we want to deliver mRNAs which drive hepatocyte expression of either (a) a protein made by the hepatocytes, is secreted systemically and acts in lung myofibroblasts to attenuate fibrosis or (b) and intracellular protein, synthesized by diseased hepatocytes which reprograms the hepatocyte to a healthy phenotype. The post-doctoral candidate will utilize in vitro and in vivo models, developed at CTI-San Francisco (CTI-SF), to mechanistically determine mechanisms associated with cellular reprograming of cell state. The candidate will work closely, but independently, with the relevant portfolio program teams at CTI-SSF.

  • Demonstrate deep scientific and technical expertise harnessed to advance our understanding in the fields of immunology, inflammation, oncology, rare disease, mRNA and/or gene editing, produce high-impact publications, present at conferences and ultimately contribute to the delivery of novel, life-changing therapies for patients.
  • Independently design and test biological hypotheses, while also leveraging the breadth of expertise available from other Postdoctoral Fellows and subject matter
  • experts across Pfizer and the external academic collaborative network.
  • Execute targeted in vitro and in vivo experiments, while leveraging state of the art technologies and resources to address fundamental questions regarding cancer drug resistance mechanisms that can uncover novel therapeutic angles in this space.
  • Generate, organize, analyze, interpret data, and identify areas where key knowledge is lacking. Proactively seek new scientific leads via genetics & AI-based resources, literature, conferences and key opinion leaders with the goal of refining scientific hypothesis and expediting experimental plans.

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.
