The Kioupakis Group
Computational Materials Physics & Discovery
What We Do
Our group develops and applies high-performance first-principles computational methods to study the properties of functional materials. Our goal is to understand and predictively model the properties of materials for electronic, optoelectronic, and magnetic devices.
Who We Are
We come from a variety of backgrounds, including Materials Science, Physics, Chemistry, and Engineering. Students pursue degrees in Materials Science & Engineering, Applied Physics, and Electrical Engineering and joint degrees in Scientific Computing as well as graduate certificate programs offered by the Rackham Graduate School.
Where We Are
We are located in the Materials Science & Engineering department of the University of Michigan, Ann Arbor. Our proximity to experimental groups with access to state-of-the-art facilities at the College of Engineering puts us at the forefront of cutting-edge collaborations.
