FDA Biomarker Analysis: Addressing the Gap Between Patient Enrollment Applications and Pharmacodynamic Effect Evaluation

U.S. Food and Drug Administration (FDA)
Silver Spring, MD Full Time
POSTED ON 8/6/2026
AVAILABLE BEFORE 9/7/2026

*Applications will be reviewed on a rolling-basis.

FDA Office and Location: A research opportunity is available in the Office of Translational Sciences (OTS), Center for Drug Evaluation and Research (CDER), Food and Drug Administration (FDA) in Silver Spring, Maryland. The Center for Drug Evaluation and Research performs an essential public health task by making sure that safe and effective drugs are available to improve the health of people in the United States. As part of the U.S. Food and Drug Administration, CDER regulates over-the-counter and prescription drugs, including biological therapeutics and generic drugs. These efforts cover more than just medicines.

Research Project: Some biomarkers have been used as multiple roles through one drug development such as a diagnosis biomarker for patient enrollment at the early stage and later drug treatment effect assessment as pharmacodynamic effect to support the drug effectiveness as a PD biomarker or an efficacity surrogate biomarker. The bioanalysis has to be adjusted accordingly to adequately fit for supporting the updated role. This research is to identify the bioanalysis gap. In this bioanalysis gap analysis.

The participant will be involved in the review of biologics license applications (BLAs) approved in recent 10 years (2015-2025) to identify biomarkers which have been used in diagnosis and assess the biomarker roles and associated bioanalytical methods to identify the landscape of a bioanalysis gap. This analysis could provide the scientifical rationales for the appropriateness of bioanalysis of biomarker in different roles to fill out the gap and improve the drug development efficacy when using biomarkers and thus expand the usage of biomarker to more drug development and thus to expedite the drug development overall and bring more drugs to patients early. 

Learning Objectives:  Under the guidance of the mentors, you will have the following learning outcomes;

  1. Learn the FDA database navigation system
  2. Learn how the biomarker assists the drug development process
  3. Master the bioanalysis of PD biomarker guidance and best practice in industry
  4. Understand the scientific considerations in regulatory decision making

Through your training, you will be able to develop strong critical thinking, improve skills in information extraction and summarization, and scientific communication.

Mentor: The mentors for this opportunity are Xiulian Du (Xiulian.Du@fda.hhs.gov) and Yow-Ming Wang (Yowming.Wang@fda.hhs.gov). If you have questions about the nature of the research, please contact the mentor.

Anticipated Appointment Start Date: 2026. Start date is flexible and will depend on a variety of factors.

Appointment Length: The appointment will initially be for twelve months, but may be renewed upon recommendation of FDA and is contingent on the availability of funds.

Level of Participation: The appointment is full-time.

Participant Stipend: The participant will receive a monthly stipend commensurate with educational level and experience.

This program, administered by ORAU through its contract with the U.S. Department of Energy to manage the Oak Ridge Institute for Science and Education, was established through an interagency agreement between DOE and FDA. The participant will receive a monthly stipend commensurate with educational level and experience. Proof of health insurance is required for participation in this program. Participants do not become employees of FDA, DOE or the program administrator, and there are no employment-related benefits.
