A determined female scientist in a modern laboratory at dusk. She’s in her early 40s, wearing a crisp lab coat over a turtleneck sweater, her glasses resting low on her nose. Her hair is neatly pulled back, and she’s intently observing a test tube under soft blue lab lighting. Behind her, shelves of equipment and glass beakers reflect the sterile but innovative atmosphere, while a faint sunset glow filters through the lab’s tall windows, adding warmth to her concentrated expression.
