     <p>Our research group consists mostly of undergraduate students interested in applying the theoretical knowledge learned in academic classes to solving real-world problems. Many of our students come from engineering majors, but any motivated student can join our group. Engineers for Exploration projects uniquely provide the opportunity to combine hands-on engineering skills with foundational academic research, allowing students to develop skills early on in their careers which are invaluable both to industry engineering positions and in graduate school.</p>
     <p>We are looking for students who are enthusiastic about engineering, technology, and exploration to participate in our research and development projects. Students must be self-motivated and excited about learning new technical skills, no matter their academic backgrounds. We especially encourage students with an interest in photography and film-making to join, since our field expeditions provide extraordinary opportunities for creating exciting media.</p>
