I am a Senior Lecturer in Algebra and Geometry in the Algebra and Geometry group in the Department of Mathematics and Statistics, part of the Faculty of Science and Technology at Lancaster University.

My research is in the area of quantum algebra. Here "algebra" refers to the major branch of mathematics that studies the structure of mathematical objects and their symmetries. A brief introduction to this area - and an explanation of the various other ways the word is used - may be found in the Wikipedia article on Algebra.

The adjective "quantum" highlights a relationship with the quantum theory of physics. In the mathematics of that theory, many of the variables do not commute - that is, *a* times *b* need not equal *b* times *a*. Many of the structures in quantum algebra have a multiplication that is not commutative. The ones I study are often not far from being commutative, though. One can often *deform* a commutative product of two elements *a* and *b* by putting in an extra parameter, *q* say, and changing the product so that now *ab=qba*. Then *ba=q ^{-1}ab* and if

More specifically, I work with Lie algebras, quantized enveloping algebras, quantized coordinate rings, partial flag varieties, cluster algebras and cluster categories. For details, please see my publications.

Previously I was Fixed-Term Fellow and Director of Studies for Mathematics at Keble College and part of the Algebra group at the Mathematical Institute, University of Oxford. I obtained my PhD from the University of London, having been based in the School of Mathematical Sciences, Queen Mary, University of London, working under the supervision of Prof. Shahn Majid.

If you are interested in studying for a PhD with me beginning in October 2020, please contact me at j.grabowski@lancaster.ac.uk to discuss this. You might also like to look at the department's list of research topics in algebra and geometry.

My lecture notes from the Kent Algebra Days PGR held in July 2014 are available online, on the talks page.
