Wallenberg Scholar Andrei Sabelfeld conducts cybersecurity research at Chalmers University of Technology with the goal of stopping cyberattacks. His focus is on software security, since software controls much of the world around us. As society has gone digital, so have thieves. Hacking can cause money to suddenly disappear, enable stolen identities to be used for fraud, allow entire companies to be hijacked – or disrupt hospitals, trains, and air travel. Ultimately, all of society could be at risk. Andrei’s research team aims to prevent these attacks before they happen.
