This fonds contains materials relating to Pierson’s research interests, and his collaborative work with graduate students and faculty from medicine, nursing, veterinary medicine, and computational science. Pierson and the reproductive biology research unit made medical history when they were the first to capture natural human ovulation, witnessed with the use of an intra-vaginal probe to produce ultrasound waves. Those original images, on video tape, form part of this fonds; as do other images and data relating to Pierson’s research in reproductive technologies.
