Theo Cacoullos’s family members have initiated a Theo Cacoullos Memorial Lecture series, starting 2022. The inaugural lecture will be delivered by Narayanaswamy Balakrishnan, McMaster University, Canada, during the Annual Panhellenic Statistics Conference. Balakrishnan has been an Honorary Member of the Greek Statistical Institute since 2007. See for more information about the lecture and Theo Cacoullos. The selected lecturer is a researcher whose contributions have been or promise to be fundamental to the development of mathematical statistics and/or probability theory and related fields. Furthermore, the suitability based on interests of other researchers within the Greek community and potential research interactions with faculty and students, in addition to her/his research or academic record, will also be given due consideration during the selection process.
