Definition: "Oksana Sergeyeva" is a person known for her work in space exploration, specifically as a NASA astronaut. The term "Oksana" could refer to the person's first name, but it doesn't specify any details about her profession. The word itself, "Sergeyev," doesn't provide enough context or detail to definitively determine the person's occupation, since the name isnβt clear. For this purpose, I'd need additional information to confirm the full definition of "Oksana Sergeyeva."
