The PhD program emphasizes advanced coursework, hands-on teaching experience, and world-class research at the forefront of the broad disciplines of chemical and biological engineering. Students are trained to become leaders in research and development in industrial and university settings.<br><br>We also foster entrepreneurial research activities. PhD students work with top researchers who are organized in three areas: biotechnology, bioengineering, and complexity, materials and nanoengineering, and energy and sustainability. We encourage interdisciplinary research interactions, including through world-class research centers and training programs that have not only garnered the department a high national ranking, but have also led to attracting students from the most competitive institutions in the world.
