Adamu Muhammad came to Iowa from Nigeria in 2008 through the U.S. Embassy Achievers Program that helps promising low income students apply to American colleges and universities. His academic prowess in science and math got him noticed by Waverly's Wartburg College. Muhammad graduated last August and after a few months at a soil testing lab in Ames, he found a job in Hartley. He works as a chemist at an ethanol plant with a shift that has him working seven days on and seven days off. He's decided in that spare time he'd like to see all of Iowa's 99 counties.
