                                            Create a realistic portrait of Jo Handelsman, a middle-aged American woman with a warm and authoritative smile, wearing a professional outfit, against a subtle background that hints at her connection to nature and microbiology, such as a faint image of a microscope or a soil texture. She should be depicted in a contemplative pose, perhaps with a book or a notebook in hand, reflecting her passion for science, education, and mentorship. The style should be photorealistic, conveying a sense of approachability and intelligence.
