Jensen Huang is out at Nvidia — who is Colette Kress, his interim replacement?

Nvidia's board announced Thursday that co-founder and CEO Jensen Huang resigned as president, CEO, and board member effective immediately, following reports of affairs with an alleged Chinese spy and a direct report; CFO and EVP Colette Kress has taken over as interim CEO while the company searches for a successor. Kress joined Nvidia in September 2013 after three years as SVP and CFO of Cisco's Business Technology Operations Finance organization and 13 years at Microsoft, including four years as CFO of the Server and Tools division; she holds a finance degree from the University of Arizona and an MBA from Southern Methodist University. The 59-year-old California-based executive, whose net worth Forbes estimates at about $1.2 billion, has been a regular presence on Nvidia's earnings calls, and the company is slated to report quarterly earnings on Tuesday.
