Job Openings

Postdoctoral Researcher, Bi Lab

The Bi lab in the Department of Cell and Developmental Biology, Perelman School of Medicine at the University of Pennsylvania is seeking two highly motivated postdocs, starting on July 1st, 2021, to conduct NIH-funded research on the mechanisms of hepatocyte polarization and apical tube formation using a rat hepatocyte cell line.  The same problems will be addressed in parallel using the mouse model by an outstanding collaborator.  The newly recruited postdocs will work in a highly supportive and interactive environment with others who study the mechanisms of cytokinesis and septin assembly and remodeling using both budding yeast and mammalian cells as the experimental systems.  All the questions in the Bi lab have been addressed using an integrative approach that combines gene editing, advanced imaging, and biochemical analysis.  Recent publications can be found at

Candidates with a Ph.D. in any biomedical science-related fields are encouraged to apply.  Preference will be given to those with experience in CRISPR/Cas9-based gene editing and live-cell imaging in mammalian cells.  Please send your CV and arrange for 2-3 recommendation letters to be sent directly to Dr. Erfei Bi (

Postdoctoral Researcher, Plachta Lab

A postdoc position is available in the lab of Dr Nicolas Plachta at UPenn.

We use advanced imaging technologies to study how mammalian cells choose their fate, shape and position in real time and in vivo. We combine imaging of live mouse embryos with molecular, mechanical and biophysical methods to study mammalian cells in their intact environment. We cover a range of topics, from how nuclear dynamics control cell fate, to how the cytoskeleton and mechanical forces drive morphogenesis of the early embryo.

The position requires a Ph.D. in cell and molecular biology, developmental biology, or imaging. Applications from candidates with strong backgrounds in other areas are also welcome.

The work will be carried out at the Department of Cell and Developmental Biology, Perelman School of Medicine, University of Pennsylvania. UPenn offers an excellent environment for cross-disciplinary programs, combining cell and developmental biology with engineering, chemistry and physics, in one of the world’s leading medical schools.

Research Associate 

The Department of Cell and Developmental Biology at the Perelman School of Medicine at the University of Pennsylvania seeks candidates for several Research Associate positions in the Academic Support Staff. This appointment will be initially for one (1) year and continuation during that time period and renewal are based on satisfactory performance and availability of funding (limited to three (3) years). Applicants must have a Ph.D. degree.

Responsibilities may include conducting studies focused on cellular processes that occur during development or that maintain homeostasis in adult organisms, such as cell division, cell motility, muscle structure and function, cell signaling and signal transduction, cell and molecular recognition. Applicants must have a Ph.D. degree and experience in the field of Developmental Biology.

The successful applicant will have an opportunity to engage in training activities such as mentoring meetings, writing manuscripts, applying for grant funding, to develop more independence in research. Apply here:

We seek candidates who embrace and reflect diversity in the broadest sense. The University of Pennsylvania is an EOE. Minorities/women/individuals with disabilities/protected veterans are encouraged to apply.
