Prof Jerome Sheahan

MSc, PhD

Biography

Qualifications:
Professor Jerome Sheahan obtained B.Sc, and M.Sc. (1/1) degrees in Mathematical Science from University College Cork, Ireland, M.Sc. in Statistics from Carleton University, Ottawa, a Ph.D. in Mathematical Statistics from University of Calgary, and is about to be awarded a Doctorate of Sciences, honoris causa from National University of Ireland Galway.
Research Interests:
Rigorous mathematical procedures in both classical mathematical statistics and robust inference (both including asymptotic theories), and applied probability.
Research and Teaching Awards:
Holder of PhD. Dissertation Fellowship, University of Calgary. Research grant recipient every year eligible from The Natural Sciences and Engineering Research Council of Canada (NSERC). Jerome has also received several teaching awards during his career. These include twice winning the President's Award for Excellence in Teaching at National University of Ireland Galway (including in the inaugural year of the award), and a National Teaching Hero Award presented to him at Dublin Castle.
Publications:
Jerome has published 1 book, about 60 refereed papers in international journals, approx. 15 published Conference Proceeding papers, and roughly 10 other published and unpublished articles.
He has thus far spent 44 years in academia in Canada and Ireland, heavily involved in all aspects of university teaching, research and service including statistical consultancy to university researchers and graduate students, and adding his name only to a small fraction of papers in which he was deeply involved in design, analysis or both..
His professional activities include the following:
Served as editorial collaborator for Journal of Criminometrika.
Refereed several papers for professional journals.
Gave numerous research talks at several institutions (some more than once), including University of Alberta (Dept. of Statistics and Applied Probability, Faculty of Education, Statistical Services Centre, Mathematical Sciences Society), University of Calgary, York University (Toronto), Dalhousie University (Halifax), Naval Postgraduate School, Monterey, California, University College, Galway, University College Dublin, Dublin Institute of Advanced Studies, University College Cork (Irish Mathematics Society Conference), Annual Meeting of Alberta Statisticians.
Gave a workshop on Experimental Design and Response Surfaces to all staff members of Syncrude Canada Ltd. (then the second-last oil company in Canada)
Supervised and examined a large number of graduate and senior undergraduate students during the past 40 years.
Performed a large amount of statistical consulting during the past 44 years for researchers within NUI, Galway and in Canada, and in Galway has given workshops to various groups including the Environmental Change Institute.
Served on a number of departmental and university committees, e.g. programme board for Environmental Science, Arts Faculty meetings representative, Examinations and Assessment Committee, College of Arts Executive Committee, and was member and then Chair of University Appeals Committee for approx.10 years. Departmental extracurricular work (much of this done with supportive colleagues) included examination of teaching matters, delivering Open Days, Science Exhibitions, other ways of advising students on career choices organizing and giving classes for Mathematical Enrichment and International Mathematics Olympiad training sessions for both male and female students, preparing mathematics examinations and solutions for our so-calked PRISM mathematics exam held annually in Ireland during Irish Maths Week, involvement in TyFriday where secondary school pupils would be invited to National University of Ireland Galway to the university to learn more about areas of research in mathematics and see what a day in the life of a mathematician is like!
Maximizing Student Happiness and Performance:
Jerome's policy is that students' happiness and learning always come first. Therefore he has spent an inordinate number of hours explaining concepts to students over a cup of tea outside of classes and tutorials.. Students suffer much from family, relationship, financial, health and social problems. Being constantly available to help them through showing them the beauty of knowledge and the pride they will feel through working hard with Jerome to meet the university standards for passing, leads to a great feeling of accomplishment for the student in succeeding despite serious obstacles, and gives Jerome enormous happiness at fulfilling his role as a teacher with high standards but with a great amount of empathy to spend extra time with the student to make concepts in a course easily intelligible.
