Postdoctoral Fellow, Tumor-on-a-chip for PK/PD Predictions Full-time

Use Your Power for Purpose

At Pfizer, our purpose is to deliver breakthroughs that transform patients' lives. Central to this mission is our Research and Development team, which strives to convert advanced science and cutting-edge technologies into impactful therapies and vaccines. Whether you are engaged in discovery sciences, ensuring drug safety and efficacy, or supporting clinical trials, your role is crucial. You will leverage innovative design and process development capabilities to expedite the delivery of top-tier medicines to patients globally.

We are looking for a highly motivated postdoctoral fellow with expertise in cell biology or biomedical engineering to join Pfizer's Pharmacokinetics, Dynamics and Metabolism (PDM) Department.

How You Will Achieve It

In this position, the postdoctoral fellow will lead the advancement and validation of microfluidic-based in vitro tumor growth inhibition (TGI) models. With a focus on early prediction of effective concentrations and dosing, this project aims to significantly influence strategies to reduce and ultimately replace in vivo TGI studies. The successful candidate will be exposed to and collaborate with colleagues in oncology biology, proteomics, Translational Modeling and Simulation (TMS) and mass spectrometry.

In this position, you will draw on your background in cell biology and your passion for developing advanced microfluidic in vitro systems to design tumor growth inhibition models for both solid and liquid tumors. You'll incorporate preclinical and clinical pharmacokinetic-pharmacodynamic (PK/PD) data to mimic relevant exposure profiles, will design the appropriate studies to monitor pharmacodynamic response, and work closely with TMS colleagues to establish and validate the correlation between in vitro and in vivo results (IVIVC).

You will also present internally and externally and publish your results from this project.

Here Is What You Need (Minimum Requirements):

• Ph.D. in Biological Sciences, Biomedical Engineering, or a related field with expertise in one more of the following areas as demonstrated through at least one first-author publication: Cell Biology, Oncology, Cell/Tissue Engineering, 3D Complex In Vitro Models/Biophysiological Systems.
• No more than 2 years of post-degree experience.
• Willingness to make a minimum 2-year commitment.
• Successful record of scientific accomplishments evidenced by scientific publications and/or presentations with at least one first-author publication in a peer-reviewed journal.
• Hands on experience in cell biology, assay design and functional readouts of probed biology (e.g., immunofluorescence, imaged-based analysis, multi-omic profiling for translational relevance).
• Strong oral and written communication skills and the ability to work independently and as part of an interdisciplinary team. Ability to adapt and distill complex scientific concepts or experimental design to the level of understanding across the interdisciplinary team.
• Strong problem-solving capability – enjoy complex challenges and driven to explore different approaches to overcome challenges.
• Strong collaborative acumen.

Bonus Points If You Have (Preferred Requirements):

• Familiarity with principles of pharmacokinetics, pharmacodynamics & metabolism.
• Strong grasp of biological systems such as oncology, pathways, and biomarkers.
• Practical experience with microfluidics/dynamic flow cell/tissue culture systems, 2D and 3D cell co-culture, spheroid/organoid culture.
• Familiarity with microfluidic chip materials, microfluidic chip design & fabrication.
• Interest and/or experience in computational modeling of PK/PD.

Physical/Mental Requirements

• Lifting, sitting, standing, walking, bending.
• Ability to perform mathematical calculations.

Non-Standard Work Schedule, Travel or Environment Requirements

• Majority of work will be performed during the standard workday, but ability to work flexible hours when needed is preferable.

Additional Information

• Work Location Assignment: On Premise.
• Relocation support: No.
• Last day to apply: September 30th, 2025.

The annual base salary for this position ranges from $62,700.00 to $104,500.00.

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.
