Sixbert Picard Muhoza

Materials Scientist

Dr. Sixbert P. Muhoza is a Materials Scientist at the United States Department of Energy’s (DOE) Argonne National Laboratory. He is passionate about developing and advancing green energy technologies.

Biography

Sixbert P. Muhoza is a Material Scientist in the Applied Materials Division within the Advanced Energy Technologies directorate at the Argonne National Laboratory. His research focuses on application-directed material customization for green electrochemical technologies. Prior to joining Argonne, he completed his Ph.D. work in Materials Chemistry at Wake Forest University where he also served as a Postdoctoral Research Associate. His research focused on developing and preserving nanomaterials at high temperature as well as their integration into solid oxide fuel cells (SOFC) electrodes.  He was born in Rwanda, where he attended his foundational education in primary and secondary schools. Upon graduating high school, he was awarded a presidential scholarship by the government of Rwanda to pursue college education in the United States. The scholarship was awarded to the top STEM high school graduates and enabled him to pursue a Bachelor of Science (B.S.) in Chemistry at Belhaven University. He envisions growing into a scientist who develops solutions to society’s most pressing challenges. Furthermore, he is passionate about and envisions collaborating with African STEM students and professionals to develop high-quality research, technologies, and products.
