MADISON, Wis. -

Gov. Scott Walker is touting Wisconsin as a leader in bioscience during a four-day global conference in Chicago.

Walker joined industry leaders Tuesday at the annual BIO International Convention. Thousands of domestic and international companies are discussing trends in pharmaceuticals, energy production and agriculture, among other things.

More than 50 Wisconsin companies, as well as associations representing the state's universities, nonprofit groups and government agencies are at this year's conference.

The conference includes opportunities for companies to network and create partnerships. Walker says it is a chance for Wisconsin to promote its bioscience community and showcase the state as a place for growth in the industry. The conference ends Thursday.
