Postdoctoral Position in Bone Tissue Engineering and Mesenchymal Stem Cell Research

Johns Hopkins University, School of Medicine, Baltimore, MD, United States

The Spinal Fusion Laboratory at Johns Hopkins University School of Medicine ( is seeking a motivated post-doctoral fellow with experience in bone and/or stem cell biology, animal models and/or tissue engineering. The overarching goal of the Spinal Fusion Laboratory is to advance promising therapies which improve patient outcomes in spinal surgery.  Our key area of research focuses on the elimination of fusion failure, also known as pseudoarthrosis. To this end we use animal models to study various strategies for improving spinal fusion outcomes, including: delivery of various growth factors and biological agents; mesenchymal stem cell-based therapies; and tissue engineering approaches. The laboratory is also interested in problems concerning overall spine health. In particular, we aim to investigate therapies for improving vertebral bone quality in patients with conditions such as osteoporosis and radiation-induced osteonecrosis that may require future spinal fusion procedures.

Currently, the majority of basic and translational spinal fusion research is conducted in general orthopaedic research labs, often in collaboration with bone biology and/or bone tissue engineering labs. The Spinal Fusion Laboratory directed by Dr. Timothy F. Witham is unique in that it approaches spinal fusion research from the perspective of a neurosurgeon and focuses predominantly on improving spinal fusion outcomes rather than more general orthopaedic applications.

Qualifications and Experience:

Applicants must have a post-bachelor’s training in biology, the medical sciences, biomedical engineering or related fields and should have a relevant publication/scientific presentation history. The ideal candidate would have experience with cell culture techniques, molecular biology techniques, animal handling, microscopy, histology, and immunohistochemistry. Biomaterials and tissue engineering research experience and/or experience with animal surgery would be an asset. Ability to work in a team and a good handle of English reading, writing and communication are required.

How to Apply:

Interested candidates should send a detailed CV with list of publications, along with a motivation letter (up to 1 page) stating the applicant’s interest in the position including: description of past research experience, key relevant competencies of the applicant and date of availability. Please add contact details for three references. All documents should be sent via e-mail to
