Prompt
Generate a realistic portrait of a mature Canadian mathematician, Donald J. Daley, in a study or office setting, surrounded by books and papers related to probability theory, stochastic processes, point processes, and queueing theory. He should be dressed in attire consistent with a university professor, possibly with glasses and a thoughtful expression, conveying a sense of deep concentration or contemplation. Incorporate subtle hints of his notable work, such as a copy of "An Introduction to the Theory of Point Processes" or a blackboard with equations related to his fields of study in the background. The style should be formal and professional, reflecting his achievements, including his fellowship in the Australian Academy of Science and his association with the Australian National University.
