IBM Research scientist Bruno Michel is a classic intellectual omnivore, with scientific interests ranging from semiconductors and computer system design to solar energy, biology and water cooling systems. His interests are just as varied in his non-professional life. He’s a serious tap dancer, a long distance hiker and a ski touring fanatic. In fact, his trips into the Swiss alps near his home in Zurich created a bridge between his personal and professional lives. Over years of repeatedly visiting glaciers in the mountains, he has seen firsthand the effects of global warming. The glaciers are shrinking. And fast. His quest as a scientist is to find ways to use less energy in computing. Here’s a video profile in which Bruno describes his career path, his motivations and some of his ideas for saving the planet.
