Postdoctoral Research Fellow (Liao Lab)

The Liao Laboratory at the Center for Craniofacial Innovation at Children’s Hospital of Philadelphia Research Institute in affiliation with the Department of Surgery is seeking a highly motivated research fellow interested in craniofacial developmental biology and genetics.  It is a particularly exciting time to carry out these studies at CHOP as we are integrating data institution-wide, across research centers, clinical informatics, deep phenotyping, genomic and multi-omic analysis of massive biorepositories of congenital conditions, cancers and pediatric diseases. We are eager to make translational advances to realize the goal of precision medicine to improve the diagnosis and treatment of congenital and pediatric conditions.


We are specifically interested in recruiting a candidate with experience in human genetics, developmental biology or disease models.  We have a robust pipeline of identifying human genes that are associated rare craniofacial conditions, where we apply zebrafish, human iPSC/organoid or mouse models to dissect the developmental genetic basis of craniofacial malformations. 


The fellow will join a collaborative group of scientists who study the basic and translational biology of facial morphogenesis, cranial neural crest specification and development. In this instance, the fellow’s work will focus on functional genomics of human candidate genes implicated in orofacial clefts. We are interested in the basic biology of epithelial development, RNA splicing, epithelial-mesenchymal transition, neural crest cell specification, migration, differentiation and potential for regeneration. We integrate the approaches of developmental and stem cell biology, and use multi-disciplinary tools to explore human tissue regeneration and disease. 


We apply the latest technology in zebrafish developmental genetics with routine use of light sheet microscopy, dyamic imaging and measurement of cell forces, CRISPR/Cas gene targeting, single-cell RNAseq (long read), Cut&Run transcriptional analysis, cell transplants, FACS, live confocal labeling and imaging, transgenics, chemical screening, and many other experimental approaches. Our laboratory has a dedicated zebrafish facility outfitted with the latest imaging, injection and cell manipulation instruments. Researchers work in modern state-of-art 6,000 square feet of open format laboratory space consisting of 24 lab benches and desks, 2 microscope rooms, 2 procedure rooms, 2 cold storage and 4-degree procedure room.  Our lab currently consists of 2 research scientists, 5 post-docs, 1 MD/PhD candidate, 2 research technicians and 1 executive administrative assistant. The laboratory space fosters interactions with other researchers working in the Center, with ample opportunities to participate in scientific seminars and professional development.

The laboratory has stable funding with extramural grants and institutional support.  There will be opportunities for eligible candidates to compete for independent funding.


Job Requirements

The candidate should have a Ph.D. or an M.D./Ph.D. and research experience in human, mouse or zebrafish genetics. Additional experience with cell culturing, microscopy, computation biology, mouse genetics, development, cell, developmental, is desirable. Outstanding oral and written communication skills are necessary. Minimum of 3-year commitment is required.

Funding, Support, Wellness and Equity

We are committed to the mentorship and wellness of developing scientists and cultivating a culture of collaborative scientific inquiry where the team provides diversity of perspectives, experiences and life experiences.  Our Center has been leading and contributing to CHOP efforts to recruit and cultivate colleagues of historically under-represented racial and ethnic groups, at all levels, from students and technicians to faculty members.


The post-doctoral fellow is well supported at Children's Hospital of Philadelphia, with a number of mentorship, networking and career development opportunities within the lab, the Center and CHOP at large.  CHOP salary scale is competitive and the latest information can be found online. In 2023 the PGY1 level is $65,500 with benefits.
