Dr John Bissell
Research Interests: Mathematical Biology
My current research lies mainly in mathematical modelling of so-called `tipping-point' systems, that is, systems which undergo transitions between markedly different states following small changes to key parameters. Present interests include:
- Behavioural transmission dynamics as epidemics
- Conformity bias and catastrophic transitions in trends or fashions
- Pedestrian flow and crowd dynamics
Research Interests: Plasma Physics
In addition to my research on `tipping points' in mathematical biology and social dynamics, I also work on related systems in the physical sciences, specifically plasma physics. In this area I focus on:
- Electromagnetic instability (especially magnetothermal instability)
- Collisional transport theory and magnetic field dynamics
- Computational modelling of transport with coupled magnetohydrodynamics
Teaching: Laplace Transforms and Multiple Integrals (Michaelmas Term 2013)
This year I am lecturing the second-year undergraduate engineering course "Laplace Transforms and Multiple Integrals" (confusingly part of the Numerical Methods series, 2H Engineering). Sets of outline notes will be posted on this page (below) in advance of lectures, while solutions to the problem sheet will be made available at the end of term:
- Lecture Handout
- Additional Comments on Example 3 of Lecture 1
- Problem Sheet
- Solutions I
- Solutions II
- Solutions III
Students: Please advise me of errors. If I correct the notes, then revisions will be uploaded throughout term.
- Computational Applied Mathematics
