Our IGERT students have had extensive networking and professional development opportunities by introducing them to recognized experts in their field. These experts span academia, government regulatory agencies, national labs, and industry. During the past year our students have had group meetings with the following IGERT visitors (in alphabetical order): James Axley (Prof – Yale), David Banks (CPP, Inc.), Cynthia Howard-Reed (NIST), Peggy Jenkins (California Air Resources Board), Mike McGinley (St. Croix Sensory, Inc.), Shelly Miller (Assoc.
