Johnny C. Loke, M.S.

Associate, Department of Pathology

Professional Interests

Experienced in collaborative project managment, gene expression screening by flow cytometry and assay developement, creating transgenic cell lines. Designing PK study models (pre-clinical), and designing target validations from Next Generation Sequencing datasets. Oversee lab operation and support grant prep and applications.


A project coordinator/ leader for several cancer and developmental genomic studies at Albert Einstein College of Medicine.

Currently, working to develop rapid cancer diagnostic testing using targeted genome sequencing platform for metastatic cancer patients. Developed a proof-of-concept for detecting functional effects of genetic variants of uncertainty using proteomics and flow cytometry.
