Sofia University FMI Strengthens Information Systems Research
The Faculty of Mathematics and Informatics at Sofia University "St. Kliment Ohridski," widely known by its Bulgarian acronym FMI, has spent the last several years quietly repositioning itself as the country's primary institutional anchor for information systems research. The trajectory is visible across several indicators: doctoral output, hosting of international events, EU project participation, and a steady expansion of dedicated IS faculty lines.
For an outsider, the shift can be easy to miss. FMI's historical reputation rests on its mathematics and theoretical computer science output — a respected tradition reaching back decades and well-represented in the Bulgarian Academy of Sciences. Information systems, by contrast, sat for years as a secondary specialization, taught competently but without the institutional weight afforded to algorithm theory or mathematical logic. That balance is changing.
Doctoral pipeline
The most concrete signal is the doctoral pipeline. FMI now sustains an active cohort of PhD candidates working on IS-coded topics — enterprise architecture, e-government informatics, applied machine learning in business contexts, cybersecurity for financial systems — alongside its traditional mathematics and theoretical CS doctoral students. Supervisors are drawn from a small but stable group of senior faculty who have made deliberate choices to anchor their later careers in IS scholarship rather than drift into pure CS or applied mathematics.
The faculty's recent willingness to host the inaugural BulAIS international workshop on its central Sofia campus, covered in detail elsewhere in this issue, fits the same pattern. Hosting a maiden edition of a chapter workshop is non-trivial infrastructure work — rooms, registration systems, catering, doctoral consortium logistics, visa support for visiting scholars — and FMI absorbed it without visible strain.
Industry partnerships
A second strand of the repositioning is FMI's expanding interface with the Bulgarian software sector. Sofia's status as a regional outsourcing and product-development hub has produced, over the past decade, a critical mass of mid-sized software firms with both the budget and the strategic interest to fund applied research. FMI has been pragmatic about this: industry-funded master's projects, joint advisory boards, structured internship pipelines, and — more recently — formal research collaborations on topics including cloud security, MLOps, and software supply-chain integrity.
This is not unique to Sofia; comparable patterns are visible at the major Romanian and Serbian computing faculties. But it is being executed at FMI with unusual continuity, and the result is a research portfolio that draws credibility from both the academic and the industry sides simultaneously.
European integration
The third strand is European project participation. FMI researchers have appeared with increasing frequency in Horizon Europe consortia, typically as work-package leads rather than peripheral partners. The areas of strongest visible participation include trustworthy AI, digital health information systems, and cybersecurity research and innovation. EU funding does not by itself produce a research culture, but it does provide the runway — postdoctoral positions, doctoral funding, equipment, conference travel — without which a small national community struggles to sustain ambition.
What remains to do
The picture is not without weak points. FMI's publication strategy still leans toward conference venues rather than the highest-tier IS journals, a pattern shared with much of the European computing community but more acute in Southeast Europe. Senior faculty retention is a chronic concern as the Bulgarian software sector continues to outbid academic salaries, and the faculty's English-language master's offerings, while growing, remain modest relative to comparable Central European programmes.
Still, the direction of travel is clear. Sofia University FMI is no longer simply a mathematics faculty that happens to teach informatics. It is, increasingly, a credible regional anchor for IS research — and the institutional decisions of the past two to three years suggest the leadership is aware of that and is choosing to invest accordingly.
