New Zealand Mathematics
and Statistics Postgraduate
Conference
The annual New Zealand Mathematics and Statistics Postgraduate
conference is organised by students for students. It provides an
opportunity for postgraduates throughout New Zealand to network,
practise presentations and gain experience of conference etiquette
in a relaxed and supportive environment. This year the conference
is in Whitianga on the Coromandel Peninsula.
Starting in 2006, the South Island Mathematics and Statistics
Postgraduate Conference (SIMaSP) was held at Queenstown for
two days. Twenty six postgraduate students and staﬀ from the
Universities of Canterbury and Otago attended. It was such a
success that the first New Zealand Mathematics and Statistics
Postgraduate Conference (NZMASP) was held in November 2007,
also in Queenstown. Since then the NZMASP conference has been
held in the following places:

Excursion
Wednesday afternoon is a free afternoon for you to spend how you
wish. Here are some suggestions, use the internet or talk to the
organisers for more information:
Whitianga Rock Walk This is a short walking track in
the Whitianga Rock Scenic and Historic Reserve just across
the Whitianga harbour.
Hot Water Beach and Cathedral Cove These are some
famous and equally as beautiful beaches on the east coast of
the Coromandel peninsula just east of Whitianga. There are
tour buses departing from Whitianga that can take you there.
Water Sports Kayaks and boats are available for hire, there
are also good diving spots and glass bottom boat tours to
experience Mercury Bay without getting wet.

Top tips for student talks
By last year’s plenary speakers: Alex James; Jeanette McLeod
and Elena Moltchenova.
Slides: Beamer, powerpoint, ...? Nobody cares. As long as your
slides look nice and are informative that’s all that matters! Check
them in a large room beforehand, can you read everything from
the back row? Do all the lines on your graphs show up on a
low resolution projector? Don’t get carried away with fancy slide
eﬀects, revealing things one at a time should aid understanding
and not just jazz up a too long list of bullet points. As a rule of
thumb no more than two eﬀects per talk. Spell-check!
Equations: Research (Fawcett, PNAS, 2012) has shown that
citations decrease as equations per page increase. The same applies
to talks. Try to use English words not mathematical symbols.
Style: Chatty talks are nice but don’t sacrifice mathematical
formality to achieve this. Experienced speakers who do this took
years to perfect it and started oﬀ by giving formal talks.
Facilities: Videos and movies are great but check they work
on the conference system and have a back up plan if they don’t.
Drawing on a whiteboard usually comes across as poor preparation,
as though you couldn’t be bothered to prepare a decent slide.
We strongly recommend you avoid doing it unless there is a true
pedagogical need.
Less is more: Don’t include your entire thesis. The aim of a talk
is to enthuse, educate and entertain your audience. Many good
speakers choose one (often small) concept from their research and
explain this to the audience. If your research topic is particularly
obscure this may need to be a fairly basic concept!
Audience: Remember to adapt your talk to your audience. A
graph theory conference participant has a diﬀerent background to a
more general conference participant. Be sure to define your terms!
For more general audiences you should spend some time motivating
your work. This is especially important for pure maths topics.
Preparation: Good talks take time to prepare. It’s very obvious
to your audience when you’ve just thrown together a talk at the last
minute. They’ve taken time from their busy schedule to listen to
you. It’s quite insulting when you haven’t taken a similar amount
of time to prepare.
Body language: Enthusiasm is a wonderful thing :-) If you don’t
look interested why will your audience be interested. Look at the
audience, make eye-contact with people. Try not to spend your
whole talk talking to the whiteboard, screen or floor.
Laser pointers: These are a curse to the nervous, they make
it obvious if your hand is shaking! For smaller rooms consider
just using your hand to point instead. If you do use one, use it
sparingly, don’t wave it around the screen constantly, it can make
people feel seasick.
Questions: Answering questions after your talk is important.
But if you do not know the answer, it is fine to say so and to follow
up later. Do not forget to thank the commenter.
Acknowledgements: Research is rarely the product of a single
person. Who is your supervisor? Who funded you? Include
references and make it clear what your contribution is.
