Leslie Krohn

Chief communications officer - Argonne National Laboratory

Leslie Krohn is the chief communications officer of Argonne National Laboratory, where she has responsibility to promote and protect the reputation of one of America’s scientific powerhouses. She spent more than two decades leading communications and marketing at the world's most admired and respected organizations. From start-ups to global multinationals, Krohn has transformed marketing and communications functions in times of economic boom and bust, growth or decline. In 2009, she took on a role leading integrated marketing for Nielsen’s $1 billion North America buy business, where her responsibilities focused on building and protecting the company’s reputation, increasing awareness of the company’s solutions and capabilities, driving client engagement through traditional and digital events, and delivering thought leadership content across diverse digital platforms. In 2015, Krohn added commercial responsibility, with a cross-industry client base spanning CPG, retail, healthcare, financial services, automotive, professional services and nonprofits. Before joining Nielsen, Krohn led internal communications for the Sara Lee Company. She spent five years building a communications and marketing function for a new business at General Electric. From inside a web consulting firm as its director of marketing, Krohn spent a year riding the dot-com roller coaster up—and was on board when it crashed the next year. She was schooled in thought leadership during her five-year tenure at Accenture, and learned the basics of marketing communications in her first role as a jack-of-all-trades marketer for an industrial trade association.
