Various research projects are undertaken by faculty, staff and students in these focus areas. Department personnel are very successful in obtaining research support from private, government, and business/manufacturing entities. These grants and awards help support many graduate students and allow considerable advantages for funding research activities and providing real-world engineering and research challenges and accomplishments. Graduate students have the opportunity to select research projects from the wide diversity of research interests of the faculty. Generally, a thesis/dissertation research project will involve both analytical and experimental investigations that rely upon the student's background in engineering, basic physical sciences, and biological/agricultural sciences. Theses/dissertations may range from being almost completely theoretical to almost completely experimental in nature. The research project is selected by the student in consultation with the faculty adviser.The following should provide an idea of the types of graduate research topics that are being (or have been) investigated:
