Prompt
Create a realistic portrait of Harold E. Varmus, a middle-aged man with a gentle expression, wearing a suit and tie, with a subtle background that hints at his medical and scientific achievements, such as a faint image of a cell or a DNA double helix. He should be depicted in a contemplative pose, with a slight smile, conveying a sense of intelligence and compassion. The style should be formal and professional, suitable for a renowned physician, biologist, and professor.
