The SFU Math Symposium is an annual event that brings together innovative research on computation and mathematics, while showcasing the computational expertise of the SFU department and of other invited speakers. Speakers: Caroline Colijn ~...

The coronavirus that was reported in Wuhan, China in December 2019 has caused much concern in the media, in scientific and in public health communities due to its human-to-human transmission, virulence and transmissibility. In this era of open data...

Ecological competition between strains of a pathogen occurs when strains compete for hosts -- either for susceptible hosts, host resources during co-infection, or the ability to re-infect hosts. Competition is important because when strains compete...

While vaccines are available and are effective in protecting against colonisation and disease with Streptococcus pneumoniae, their effectiveness is limited by strain (serotype) replacement following widespread vaccination. Understanding the post...

Improvements in sequencing technology mean that we have rich data on how infections evolve and spread. In this talk I will describe two settings where this calls for new mathematics. Trees -- in the sense of graphs with no cycles -- are a cornerstone...

New kinds of data are giving rise to exciting new opportunities in public health. The recent revolution in DNA sequencing means that for the first time, we can read the sequences of viruses and bacteria that cause human disease. This allows us to...
