I am happy to advertise a new open-access journal "Higher structures" where I serve on the editorial board. Its website is accessible via the URL If your research is related to the scope of this journal, please do consider publishing a paper there.


In collaboration with Murray Bremner, I wrote a book "Algebraic Operads: An Algorithmic Companion".

Table of Contents:

1. Normal forms for vectors and univariate polynomials
2. Noncommutative associative algebras
3. Nonsymmetric operads
4. Twisted associative algebras and shuffle algebras
5. Symmetric operads and shuffle operads
6. Operadic homological algebra and Gröbner bases
7. Commutative Gröbner bases
8. Linear algebra over polynomial rings
9. Case study of nonsymmetric binary cubic operads

Research supervision and mentorship

In 2017-20, I am supervising the PhD thesis of Pedro Tamaroff, who works on a number of topics in homological and homotopical algebra, his current research outputs are this paper he wrote himself, this paper we wrote together, and this paper he wrote himself.

In 2019/20, I was a mentor of Vincent Gélinas during his time as a postdoc at the Hamilton Mathematics Institute.

In 2017-19, I supervised the Masters thesis of Norah Alghamdi who worked on Gröbner bases for nonsymmetric operads and their applications; her work resulted in a thesis "The associative filtration of the dendriform operad".

In 2016-18, I was a mentor of Victoria Lebed during her time as a postdoc at the Hamilton Mathematics Institute; she is now a maître de conférences at Université de Caen - Normandie.

In 2016, I was a mentor of José Moreno during his exchange visit to Trinity College Dublin as a part of his PhD studies in Malaga. José then was a postdoc at MPIM Bonn, and in September 2019 is moving to Trinity College Dublin to start a competitive research fellowship awarded by the Irish Research Council.

In 2014/15, I supervised the Masters thesis of Soutrik Roy Chowdhury who studied an important computational method of homological algebra, the Anick's resolution.

In 2013/14, I supervised the Masters thesis of Lucas Mason-Brown who studied invariant (coordinate-independent) operations that map various differential-geometric constructions to one another.

For prospective postgraduate students

This webpage and various materials linked here (my papers, slides and videos of my talks etc.) should give you some ideas about the range of my research interests, as well as my style of doing maths. At any time, I have suggestions for PhD projects in a few areas of my immediate interest, however, if you have some ideas of your own for topics to work on, I would be happy to discuss these ideas, and possibly either serve as a supervisor for such a project or suggest a more suitable supervisor.

Doing research in maths is great fun, and I assume you share this opinion if you are reading this. However, it does not hurt anyone to bring a bit of structure in that fun: while typical problems you encounter in tutorials and exams during your undergraduate studies are designed in a way that one can finish them in 15-20 minutes, actual research questions can take days, weeks, months, and in some famous cases years of work. Approaching them without any system would not thus take one too far. There are some good examples of guidelines towards systematic mathematical reasoning (suggestions will depend a lot on who you ask for guidelines). I would recommend to have a glance at an excellent essay "Why is it plausible?" by Barry Mazur, and then maybe even follow to one of the sources he references, "Mathematics and Plausible Reasoning: Induction and Analogy in Mathematics" by George Polya.

Ideally, you will have completed an undergraduate degree in maths that includes some research experience, such as a final year project, or a summer research internship, but in principle previous research experience, especially for a master student, is not mandatory. I strongly believe that apart from interest in maths, the only two qualities that someone aiming to do research in pure mathematics should develop at an early stage is, first, being prepared to work hard, and, second, not being discouraged too easily: unlike many other research areas, in pure maths we work with concepts, and this means that on many occasions working on a problem would continue without much tangible progress for quite a while (unlike doing experiments in a lab, let us say), and this can be seriously frustrating. However, over time your knowledge of a problem grows, and at times you will be rewarded by that unique feeling of having found something new and cool, and this kinda makes it all worth your while. Keep that in mind, and work hard, and we shall get along well.

On a more practical side: currently, the situation with funding for Masters and PhD in Ireland is tricky, but there still are quite a few ways for a motivated student to get funded. In any case, if you are considering me as a prospective supervisor for your PhD or Master thesis, please let me know at your earliest convenience; sometimes knowing that a good candidate for a postgraduate research position exists is crucial for securing funding that is suddenly made available.

My favourite instances of mathematical writing

There are three pieces of mathematical writing which I like a lot, both because of lovely style of writing and because of nearly infinite potential for discovering new amazing things about maths while reading them, regardless of how many times you read them before. These are Ian Macdonald's book called "Symmetric functions and Hall polynomials" (2nd edition) where every other fact mentioned in examples and exercises leads to a separate exciting mathematical story, Daniel Quillen's article "On the (co-)homology of commutative rings", featuring the most fantastic style of maths writing, and Victor Ufnarovskij's survey "Combinatorial and asymptotic methods in algebra" which is sort of similar to Macdonald's book but almost without theorems and proofs between examples and exercises.
