Irene Sciriha
Maltese mathematician
Irene Sciriha Aquilina is a Maltese mathematician specializing in spectral graph theory and chemical graph theory. A particular topic of her research has been the singular graphs, graphs whose adjacency matrix is a singular matrix, and the nut graphs, singular graphs all of whose nontrivial induced subgraphs are non-singular. She is a professor of mathematics at the University of Malta. She is a Fellow of the Institute of Combinatorics and its Applications.
Education and career
Sciriha studied mathematics at the University of Malta, earning bachelor's and master's degrees as the only woman studying mathematics or physics there at that time. She completed a PhD in 1998 at the University of Reading in England. Her dissertation, On some aspects of graph spectra, was jointly supervised by Anthony Hilton and Stanley Fiorini, and she also worked with Nash Williams, David Stirling and Peter Rowlinson.

“Irene Sciriha” enters the record as maltese mathematician. Crown Archives preserves that source wording while asking what Irene, Sciriha and Maltese can confirm, complicate or overturn.
Why this record matters
“Irene Sciriha” is worth following because a concise public description often conceals a longer documentary argument. Here, Irene, Sciriha and Maltese provides the most credible route into that argument.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q86756309. VIAF identifies the subject as 194154440121735340147. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1998 and 1971.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Read biographical claims against dates, named institutions and the cited references. Distinguish a subject’s later reputation from evidence produced during their lifetime.
- Establishing names and roles
- Building a first chronology
- Locating cited institutions
