Research Specialist B/C
Job Profile Title
Research Specialist B
Job Description Summary
The position will support the advancement of new therapeutics toward the clinic and contribute to the scientific work published from the lab. Its focus will be testing new engineered T cells and evaluating their functional activity, as a single agent or in combination, to enhance therapeutic T cell performance, particularly within tumor microenvironments. Both positions requires solid immunological laboratory skills, including CAR T cell manufacturing, flow cytometry, ELISA, and other in vitro assays, as well as experience with in vivo mouse studies, contributing to efforts to enhance the therapeutic index of these therapies and understand their resulting impacts within the tumor microenvironment.
The primary function of this Research Specialist B position is to conduct in vitro and in vivo mouse studies, and assist with day-to-day operation of the research bench, all within the BRITE (Shobaki) Lab under the direction of Nour Shobaki. The purpose of this position is to support mouse studies by generating and characterizing engineered immune therapeutics, growing and developing tumor cells, performing injections, monitoring animal health, weight, and therapeutic responses, and collecting datasets from the study (tumor growth, therapeutic engraftment, histology, ex vivo assays). This position also documents and organizes experimental data and contributes to the preparation of presentations and research publications, under the guidance of the Principal Investigator.
The primary function of this Research Specialist C position is to independently design, troubleshoot, and carry out in vitro and in vivo mouse studies, maintain the animal colony, and manage day-to-day operation of the research bench, all within the BRITE (Shobaki) Lab under the direction of Nour Shobaki. The purpose of this position is to establish mouse studies by generating and characterizing engineered immune therapeutics, growing and developing tumor cells, performing injections, monitoring animal health, weight, and therapeutic responses, and collecting datasets from the study (tumor growth, therapeutic engraftment, histology, ex vivo assays). This position also generates and organizes the experimental data needed to support grant applications and IND-enabling studies, and contributes written sections to progress reports and manuscripts, with final authorship and submission led by the Principal Investigator.
