Irene Sciriha graduated BSc mathematics/physics, MSc (University of Malta) and PhD in Graphs/Linear Algebra (University of Reading (UK)). She lectured at the University of Malta 1971-1974 and since 1987. She is currently professor of mathematics, teaching algebra and the spectra of graphs. Professor Sciriha served as Department of Mathematics representative on the Science Faculty Board and is currently chair of the faculty's research ethics committee. She was chair of various university senate and council sub-committees including Gender Issues, Auditing Faculty of Theology, and Auditing Institute of Agriculture. She also served on the Quality Assurance, the Staff Development, Students' Charter, AWR, and the Lisbon Convention Diploma Supplement Committees in accordance with the associated standards of the Bologna Process.
Professor Sciriha taught mathematics, physics and computer science at sec- pre-university level. She represented the Math dept on the national Science-Education Division Committee for Development of Math Courses at pre-university levels and on the Matsec syllabus panels since the preparatory years for the setting up of the Matsec system in Malta. She is still an active member of the revisers and marking team .

She publishes regularly in the areas of her research interests in abstract algebra, which extend to spectral graph theory, molecular chemistry and computer science. She is also an associate editor for the international journal Graph Theory Notes of New York, and is also referee for international journals including Elsevier's and ISRN journals. World Scientific and Engineering Academy and the American Mathematical Society have appointed her as a reviewer of published papers.

Internationally, Prof Sciriha has been recognized as expert in her field and is occasionally asked to give plenary sessions at conferences. She represented Malta on the Helsinki Group of the European Commission, promoting women in research for ten years and was formerly elected as the president of the European Women in Mathematics . On a national level, she was often consulted on policy documents on science and women as academics-decision makers. During the CHOGM conference held in Malta, she convened the People's Forum Gender and the Digital Divide meeting.
