Many planar spatially extended systems exhibit localized standing structures such as pulses and oscillons. In particular, such structures can emerge at Turing and forced Hopf bifurcations. In this talk, I will give an overview of these mechanisms and show how geometric blow-up techniques can be used to analyze them: among the findings is the bif...

While the theory of nonlinear waves in partial differential equations is very well developed, understanding travelling waves in systems posed on lattices is challenging, and many basic questions remain open. Indeed, travelling waves on lattices can be found only by solving functional differential equations of mixed mode, which are ill-posed as i...

Each of these three posters contains a piece of digital art exploring an aspect of life during the COVID-19 pandemic. The first poster contains a digital drawing of a laptop computer with a Zoom meeting on the screen. The people in the grid are featureless andare set against colorful backgrounds. Keys on the keyboard spell out the word "caged." ...
