Biography

Peter D. Usher is a Professor Emeritus at Eberly College of Science, with interests in perturbation theory, quasars, modern cosmology, and the intersections of science and Shakespeare. He contributed to the understanding of how the works of Shakespeare can be analyzed through the lens of scientific inquiry, particularly in the realm of astronomy. Usher has a notable publication, 'Shakespeare's Knowledge: Astronomy Birth Modern Cosmology' (Peter Lang, 2022), which discusses the relationship between astronomy and early modern literature. He has presented his research at significant scientific meetings, including the 241st meeting of the American Astronomical Society, where he discussed empirical disproof of Ptolemaic geocentrism in relation to sixteenth-century scholarship. Usher engages with the implications of Shakespeare's texts in a modern context and remains active in the academic community.
