Michael Friedmann

I have been around: grew up in Chile and Mexico, learned my ABC’s in California, did my BSc & MSc in Agriculture in Israel (and had to learn Hebrew while doing that!). Then a PhD from Washington State University on signal transduction in plants. Post-docs studying protein kinases in cancer cells and signaling pathways in immunological responses at the NIH.

So, I have been studying plants at the molecular, cellular and whole plant levels, both in laboratory and field settings. Throughout my research career, I have applied molecular and/or genomics tools to study various aspects of plant biology including abiotic and biotic stress responses, secondary cell wall formation, fruit ripening and yield, as well as responses to plant growth regulators and tropic stimuli. My prime interest has been signal transduction and the control of gene expression, both in plant and mammalian systems. At present, I am the Project Manager for an applied genomics project at the University of British Columbia led by Dr. Carl Douglas, developing genomics tools to enhance poplar development as a feedstock for biofuels production. Consequently, over the last several years, my interests have been mainly in the control of secondary cell wall formation. In addition, before coming to Canada, I worked for several years in vegetable breeding, developing tomato cultivars with enhanced shelf life (less post-harvest losses) and resistant to severe insect-transmitted viruses (reduced pesticide use). These were desert-grown tomatoes, and I could take home the pick of the crop-the best salads!

I have lived in several countries, love all kinds of ethnic food, and cook very good Mexican food. Love to travel, hike, swim in the ocean (warm only), watch all kinds of movies, and hang out with friends and family (and Ebby, our little dog).
