Prompt
Generate a realistic image of a middle-aged American man, likely in his office or a university setting, surrounded by books and academic materials. He is sitting in a thoughtful pose, perhaps with a pen in hand and a notebook or book open in front of him. He has a kind and introspective expression on his face. Incorporate some subtle hints of his work in sustainable enterprise and environmental policy, such as a globe or a recycling symbol in the background. The style should be formal and professional, reflecting his occupation as a professor and author.
