 is a faculty member in the Department of Plant and Environmental Sciences at the Weizmann Institute of Science. Prof. Milo is working to harness the tools of systems biology research (Systems Biology) to environmental and sustainability challenges. His lab investigates the processes of photosynthesis and carbon sequestration, which are the world’s natural engine for converting solar energy into sugars. These Processes are also the source of human food and the dominant systems determining the composition of the atmosphere. Ron’s studies concentrate on examining the possibilities of carbon-based metabolism pathways in an attempt to understand the basic design principles which convened during millions of years of evolutionary experiments. The aim of the study is to increase our understanding on how to improve our ability to produce food and fuel more efficiently. In recent years, his lab has lead research in quantifying the environmental impacts of production and consumption of animal-based products – another important metabolic pathway for humanity, occuring on a regional and global scale. Prof. Milo is the founder and developer of BioNumbers, a database of useful numbers in biology for researchers and the general public.
