Welcome!

You have reached the online home of FLAReLab, the Formal Languages and Automata Research Lab. We are a part of the Department of Computer Science at St. Francis Xavier University in Antigonish, Nova Scotia, Canada.

About Us

In the same way that a flare illuminates the dark sky, research in theoretical computer science sheds light on the many unknowns scattered across the rest of computer science. Theoretical research forms the foundation of the study of computing, and although the interest in and value of “hot topics” ebbs and flows, theory is a constant presence lending perpetual insight to researchers and practitioners alike.

The members of FLAReLab study fundamental problems in formal language theory and automata theory together with select applications of these theoretical notions, intersecting with areas such as algorithm analysis, bioinformatics, coding theory, and software engineering. FLAReLab research has been presented at top international conferences and published in leading computer science journals, and its members have received a number of awards and accolades.

FLAReLab is led by Taylor J. Smith, an assistant professor in the Department of Computer Science at St. Francis Xavier University.

November 19, 2024StFX University News

It should come as no surprise to anyone familiar with StFX that our campus is filled with highly engaged students, educators, researchers, and leaders. Academic X’cellence shines a spotlight on members of our educational community to find out more about their unique experiences—both inside and outside of the classroom.

Alley Heaps internship allows computer science students to tackle big research questions

September 11, 2026StFX University News

Can experienced programmers really tell when code was written by AI? Does sounding confident after a hockey game actually mean a team played well? And how can machine learning help in medical research? These are questions three StFX computer science students spent their summer exploring, thanks to the Alley Heaps Undergraduate Research Internship.

StFX research internship leads to solution of 11-year-old mathematical conjecture

August 26, 2026StFX University News

This summer, an undergraduate research internship at StFX, made possible through the Mitacs Globalink Research Internship program, has led to the resolution of a mathematical conjecture that had remained unanswered for over a decade.

Projects

Two-Dimensional Formal Languages and Automata Theory


A major interest of FLAReLab lies in the study of formal languages and automata theory in two dimensions. Although going from strings to arrays may not seem like a big change, adding another dimension increases the computational power of a finite automaton drastically. FLAReLab members study fundamental properties of the two-dimensional automaton model together with applications to other areas of computer science, such as data storage and image recognition.

Visual Representations of Automata


Building on the Grail software package, members of FLAReLab created a software tool that takes Grail output and generates a visual representation of a finite automaton in LaTeX/TikZ code. The generated figure can then be added to research papers or educational materials, saving authors considerable time versus producing the figure manually. This work received the Computer Science Communication Award at the Science Atlantic MSCS 2022 conference.

Bio-Inspired Language Operations


Certain biological and genomic operations, such as insertion, deletion, splicing, and mutagenesis, can be modelled formally using language operations. In a collaboration with researchers from South Korea, members of FLAReLab studied these bio-inspired language operations and proved a number of decidability and algorithmic results that, taken together, establish the power of this modelling technique. Combining formal languages with bioinformatics may help future researchers uncover new findings without the need for a wet lab.
