Prompt
Generate a realistic image of a middle-aged American man with a friendly expression, wearing a casual yet professional outfit, sitting in front of a computer or a laboratory setup, surrounded by subtle hints of his work in computer science and synthetic biology, such as circuit boards, petri dishes, or a laptop with code on the screen; he should be in a thoughtful pose, perhaps with a pen in hand, and have a few distinguished gray hairs, conveying a sense of experience and intelligence; the background should be a muted, neutral color, allowing the subject to be the main focus, and the overall style should be a photorealistic portrait.
