Furthermore, his long-term collaboration with Michael Baake (University of Bielefeld) and various Canadian research groups has resulted in the monograph Aperiodic Order (Cambridge University Press), a foundational text in the field. Strungaru’s chapters on "Almost Periodic Measures" are widely praised for their clarity and depth.

For decades, the definition of a "crystal" in physics was rigid: it was a structure where atoms are arranged in a periodically repeating pattern. However, the discovery of quasicrystals in the 1980s—materials that are ordered but not periodic—shattered this definition and opened a new frontier in materials science and mathematics. These structures possess a symmetrical beauty that defies traditional repetition.

This prestigious appointment reflects his status as a thought leader in the mathematical sciences.

has published extensively in top-tier peer-reviewed journals, including:

In the vast intersection of mathematics and quantum physics, few problems are as deceptively simple yet profoundly deep as understanding the nature of electrons in a material. If the atoms are arranged in a perfect crystal, the mathematics is (relatively) tidy. If they are arranged randomly (like in a glass), the problems shift to the realm of probability and disorder. But what happens when the arrangement is perfectly ordered, yet never repeats?

Strungaru has worked extensively to prove that the labels identifying these gaps are not arbitrary numbers but are tied to the Cohomology of the underlying dynamical system. In plain English: he helped prove that the fingerprints of a quasicrystal (the gaps in its energy spectrum) can be "counted" using topological invariants. This work connects mathematical physics to algebraic topology, providing a tool to predict the electronic properties of real-world quasicrystals.
