Bryan Rosales is a postdoctoral researcher in the Chemistry and Nanoscience Center at NREL in Lance Wheeler’s group. At NREL, he synthesizes novel chromogenic materials and develops switchable photovoltaic windows.
Rosales received an associate's degree from Columbus State Community College in 2011 and then a bachelor's degree in chemistry from The Ohio State University in 2013, where he performed undergraduate research with Professor Anne Co developing Sn anodes for lithium-ion batteries. He then received his doctorate in chemistry from Iowa State University in 2019 under the guidance of Professor Javier Vela. His graduate research focused on determining how different synthetic methods affect phase-segregation in metal halide perovskites by 207Pb ssNMR, developing the low-temperature synthesis of colloidal semiconductor nanocrystals based on earth-abundant and environmentally friendly elements, and fabricating solar cells based on binary and ternary chalcogenide colloidal semiconductor nanocrystals.
