Swampscott resident Ann Eskesen is scheduled to testify and she plans to talk in part about her role in pioneering SBIR 30 years ago. By directing federal research and development money to businesses with 500 or fewer workers, Eskesen said SBIR spurred innovations in 1,500 Massachusetts businesses and 22,000 across the country.

Eskesen is president of Swampscott-based Innovation Development Institute, tracking SBIR projects.

“We have created with SBIR money the largest single concentration of technical talent anywhere,” Eskesen said.

The two-hour hearing is a chance for Moulton, a Democrat, to underscore his commitment to work with House Republicans.

“It’s a bipartisan hearing and another example of work that can be done across the aisle,” he said.

Hanna is a New York Republican who, according to a statement released by Moulton’s office, is committed to ensuring that congress approves funding reauthorization for SBIR.

“In the rapidly growing and ever-changing field of technology, it is often small firms that develop innovative technologies that become staples in the marketplace years later,” Hanna stated.

The Tuesday hearing is one of five Small Business Committee hearings planned throughout the country. Mayor Judith Flanagan Kennedy said she is honored City Hall is hosting one of the hearings.

“Congressman Moulton has put a lot of effort into helping the city with its economic development.” Kennedy said.
