## Andrey Kutepov

Software Developer

Andrey Kutepov started his BNL appointment and joined Comscope in June 2017. His research field is the GW approximation and its diagrammatic extensions to study the electronic structure of solids. For Comscope, Andrey continues to work on the corresponding computer code FlapwMBPT, focusing mostly on the efficient solutions of Hedinâ€™s equations with non-trivial vertex. During his career, Andrey benefited greatly from collaboration with Anatolii Shklovskii who was his solid state physics teacher at Chelyabinsk State University (Russia), and, later, from collaborations with Gennadii Sin'ko (RFNC, Snezhinsk, Russia), Sergey Savrasov (UC Davis), Gabriel Kotliar (Rutgers University), and Vladimir Antropov (Ames Lab, Iowa).
