PhD Opportunities

If you are interested in doing a PhD in the areas of discrete mathematics, combinatorics, or discrete complex systems then I would be very happy to discuss this possibility with you, so please drop me an email at mark.dukes@ucd.ie at the earilest opportunity. If you already have funding then the process is easier. Please be aware the UCD has a Minimum English Language Requirement for prospective students and information on this is here. If you do not have funding in place, then here is some information regarding potential sources:

• Government of Ireland Postgraduate Scholarships. The deadline for applying is usually the beginning of November the year before the position is due to start. Such applications require quite a non-trivial amount of work and I recommend coming to see me no later than 1st September 2020 if you are considering this for a September 2021 start.

Teaching

All material for current undergraduate courses can be found on UCD's latest e-learning system.

2020–2021:

• MATH20270: Theory of Games
• MST30040: Differential Equations
• MATH30290: Mathematical Logic
