AMHERST, Mass. – Patricia Fox, of Westford, who graduated this month from the University of Massachusetts Amherst with a degree in civil engineering, is a complicated and talented young woman. She qualified this spring to be a cheerleader for the New England Patriots football team. She also has a passion for historic preservation – the field she desires to work in as a professional engineer. And this year, Fox traveled to Kenya to help provide clean drinking water for about 3,000 people in the western part of the country. The trip was organized by the UMass Amherst chapter of Engineers Without Borders, an organization that works in Third World countries.
