Dr. Ijad Madisch (38) is co-founder and CEO of ResearchGate, the professional network that connects the world of science and opens up research to all. Following his own frustrations as a researcher isolated in his lab, Ijad founded ResearchGate in 2008 together with his friends, fellow physician Sören Hofmayer and computer scientist Horst Fickenscher. ResearchGate has since grown to more than 15 million scientists around the world. They use the network to collaborate, and share their past and present research, including work that's traditionally not shared such as current research, raw data and negative results. Ijad earned his doctorate in the field of virology, while also studying computer science on the side. He spent several years working as a researcher at Massachusetts General Hospital in Boston, focusing on tissue engineering and radiology. Under Ijad's leadership, ResearchGate has attracted a group of renowned investors, including Bill Gates, Benchmark, Founders Fund, Goldman Sachs Investment Partners and Wellcome Trust.
