Cellular polarization plays a critical during cellular differentiation, development, and cellular migration through the establishment of a long-lived cell-front and cell-rear. Although mechanisms of polarization vary across cells types, some common...

Graphs with no odd circuits are well understood. In 1992, Maffray characterized all graphs whose odd circuits only have size three. Oxley and Wetzler generalized this result to binary matroids in 2016. We give a complete characterization of all...

What does mathematics, materials science, biology and quantum information science have in common? It turns out, there are many connections worth exploring. I this talk, I will focus on graphs and random walks, starting from the classical mathematical...

Mathematical biology presents very many exciting scientific challenges. In this talk I will focus on five: understanding the process of biological pattern formation, analysing the dynamics of spreading populations, assessing the emergence of...

In The Hitchhiker’s Guide to the Galaxy, by Douglas Adams, the number 42 was revealed to be the “Answer to the Ultimate Question of Life, the Universe, and Everything”. But he didn’t say what the question was! I will reveal that here. In fact it is a...

There are various iterative approaches for solving unconstrained optimization problems. Between them, the non-monotone technique is a popular approach for improving the iterative algorithms in optimization. The non-monotone technique not only can...

The theory of random graphs is one of the most developed parts of modern combinatorics. This theory was initiated by Erdos and Renyi in the early 60’s and has evolved into a deep and beautiful area of study with numerous applications. Several...

Given two disjoint sets W_1 and W_2 of points in the plane, the Optimal Discretization problem asks for the minimum size of a family of horizontal and vertical lines that separate W_1 from W_2, that is, in every region into which the lines partition...

Over the last forty years, most progress in four-dimensional topology came from gauge theory and related invariants. Khovanov homology is an invariant of knots in of a different kind: its construction is combinatorial, and connected to ideas from...

Mathematics on the Indian subcontinent has been flourishing for over two and a half millennia, and this culture of inquiry has produced insights and techniques that are central to many of our mathematical practices today, such as the base ten decimal...
