STS Research Associate/Senior Research Associate - Genetics and Genome Sciences


Title: STS Research Associate/Senior Research Associate

Department: Genetics and Genome Sciences

School: Medicine

Location: Wolstein Research Building

Supervisor Name and Title: Ronald Conlon, Professor of Genetics and Genome Sciences and Director of the Case Transgenic and Targeting Facility



Working under general supervision, plan and carry out core functions in accordance with general plans.

This position will work with animals.

The position is lab-based and on-site.

This position will work closely with the core director and--along with the rest of the core--support the research of the biomedical institutions affiliated with Case Western Reserve University through the generation rederivation and preservation of mouse genetic models.

This position is within a core which supports the work of local researchers, but in some cases research on methodologies and technologies may be conducted within the core itself. 

The Case Transgenic and Targeting Facility ( of Cleveland's Case Western Reserve University is a leader in creating gene-edited mouse models for basic research and for translation of novel therapeutic approaches ( We seek to grow our existing gene editing services with the addition of a microinjectionist.

The individual we are looking to hire will have experience and success as a microinjectionist. The primary role of this position is the generation of gene edited mice through microinjection or electroporation and embryo transfer. Additional roles include blastocyst injection, intracytoplasmic sperm injection, rederivation, cryopreservation, in vitro fertilization, and reanimation of cryopreserved mouse strains. 

The Case Transgenic and Targeting Facility of Cleveland's Case Western Reserve University School of Medicine is a leader in CRISPR/Cas gene editing. We have been in continuous operation for over 20 years, and our success in gene editing has given us the opportunity to grow. We garnered grant support from JobsOhio and philanthropic support from the Research Institute for Childrens Health to hire an additional microinjectionist. We have long term support from the School of Medicine Case Western Reserve University, the Case Comprehensive Cancer Center, the CWRU Clinical and Translational Science Collaborative, and the Cystic Fibrosis Mouse Resource Center and a broad user base of regional researchers. Join us, in beautiful affordable Cuyahoga County.
