Education/ Resume:

Assistant Professor David (Dedi) Meiri comes from a highly diverse background. He holds an M.Sc. in biochemistry and a Ph.D. in plant biotechnology from Tel Aviv University. He conducted his postdoctoral fellowship at the Ontario Cancer Institute, where he focused on the role of the GEF-H1 protein in tumor invasion and metastasis, receiving in a short time worldwide recognition as an expert in the fields of G-protein coupled receptors and small GTPases. Upon completion of his postdoctoral fellowship, Dr Meiri took a position at the Technion – Israel Institute of Technology, where he heads the “Laboratory of Cancer Biology and Cannabinoid Research” and a member of the Technion Integrated Cancer center.

Research Summary:

Our laboratory investigates the vast therapeutic potential of naturally-occurring cannabinoids and other bioactive components in various species of cannabis, algae, mushrooms and from the human body. On top of other research being conducted in the lab, our main current research interest is how these components affect various types of cancer, inflammatory diseases and disorders of the nervous system (Epilepsy, Alzheimer, sleep disorders and more). Our lab uses genetically engineered mice and a wide variety of cell lines to elucidate the molecular mechanisms of cannabinoids’ function. The lab consists of a highly trained team of skilled professionals, working in synergy to achieve the highest level of results, to better understand the complexity and diversity of cannabinoids and other natural components, and realize their full therapeutic potential for human health.
