About the O’Brown Lab:

The O’Brown Lab at Rutgers University is unraveling the intricate mechanisms that govern the blood-brain barrier (BBB) — a specialized vascular interface that protects the brain and regulates the flow of ions, nutrients, and immune cells. The lab's work focuses on how the BBB forms and functions during development, and how its breakdown contributes to neurological diseases. Our research integrates molecular, developmental, and vascular biology to inform future therapeutic applications.

About the Role:

We are seeking a highly motivated and independent Postdoctoral Scientist to join our in-person, cross-disciplinary team. This role focuses on understanding the developmental and cellular mechanisms that regulate blood-brain barrier function using zebrafish and mouse models. Projects aim to define how vascular and surrounding neuronal and glial cells interact during development, how these interactions are disrupted in disease, and how those insights can guide translational research.

The position involves designing and executing experiments, overseeing undergraduate researchers, and collaborating closely with Dr. O’Brown and other lab members in a fast-paced, discovery-driven environment.

What You’ll Get:

• Close mentorship from Dr. O’Brown and the opportunity to mentor junior trainees.

• A focus on career development, with support for producing publications.

• Active guidance for both academic and industry career pathways — BBB research is highly applicable to both.

• Ongoing networking support, including conferences and collaboration opportunities.

• The opportunity to shape the direction of a growing, high-impact lab working at the intersection of development and neurovascular biology.

What you will do:

• Lead independent research projects focused on vascular biology and BBB development.

• Conduct experiments in zebrafish and mouse models, including microinjections, live imaging, and behavioral studies.

• Apply molecular biology techniques including PCR, cloning, and genotyping.

• Perform in vivo imaging and high-resolution microscopy to visualize vascular function and BBB dynamics.

• Analyze or support RNA sequencing experiments.

• Supervise undergraduate trainees and contribute to an open, collaborative lab culture.

• Document and present findings in internal meetings and scientific publications.

What You Bring:

• A Ph.D. in Developmental Biology, Molecular Biosciences, or a related field (e.g., Genetics, Systems Biology).

• Prior experience with in vivo techniques, ideally in zebrafish (preferred) or mouse models.

• Hands-on skills in vascular biology, developmental imaging, and/or blood-brain barrier research.

• Experience with RNA sequencing workflows, data interpretation, or collaboration with sequencing teams.

• Proficiency in molecular biology techniques such as cloning, PCR, and genotyping.

A strong sense of independence, with the ability to manage and lead scientific projects autonomously.
