Prompt
Create a realistic portrait of Timothy L. Killeen, a middle-aged British-American man with a professional and approachable demeanor, wearing a suit and standing in front of a backdrop that subtly suggests his connection to the University of Illinois System, such as a UI logo or a university building. He should be depicted with a warm smile, reflecting his role as a scientist, academic administrator, and President of the University of Illinois System. Incorporate subtle elements that hint at his background in atmospheric science, such as a faint image of a globe or a stylized representation of atmospheric layers in the background. The overall style should be formal, dignified, and representative of his professional achievements and contributions to the fields of science and education.
