After several decades in influential leadership roles, as president of Harvard University, secretary of the U.S. Treasury (in the Clinton administration) and chief economist at the World Bank, Lawrence Summers has returned to the Economics faculty at Harvard and will be in La Jolla on April 30 to address the University of California, San Diego Economics Roundtable.

Summers will share his insights about the global economy and U.S. economic policy in a talk entitled "The United States and the Global Economy."

Summers earned his doctorate in economics at Harvard in 1982, became a tenured professor there one year later and took leave in 1991 for the top economist position at the World Bank. He served in the U.S. Treasury for most of the 1990's, first as undersecretary for international affairs, and was named secretary in 1999. Summers was president of Harvard from 2001 until he resigned in 2006, under pressure for expressions about women's aptitude for science and engineering.

The public is invited to attend the Economics Roundtable, which will be held, beginning with breakfast at 7:30 a.m., at the Faculty Club on the UCSD campus. The fee of $50 includes parking, continental breakfast and Summers' presentation. To register, visit www.econ.ucsd.edu/roundtable or contact Edie Munk at (858) 822-0510.
