## NZMS Research Award

This annual Award was instituted in 1990 to foster mathematical research in New Zealand and to recognise excellence in research carried out by mathematicians in New Zealand. **This Award is based on mathematical research published in the last five calendar years (2014-2018). This could include research published in books, journals, other peer-reviewed venues, or other types of high quality mathematical research.** This assessment period may be adjusted to take into account an interrupted career pattern. Candidates may contact the NZMS President in confidence for clarification of how the adjustment of time period applies to the their particular circumstances. To be eligible for the Award, a candidate must be a current member of the NZMS and must have been a resident of New Zealand for the last three years.

Nominations and applications should include the following:

- name and affiliation of candidate;
- statement of general area of research;
- a CV including: distinctions awarded, full list of graduate students supervised, full list of grants received (including names of co-investigators), full list of publications (including names of coauthors); publications from the 2014-2018 assessment period should be highlighted;
- if appropriate, a justification for an adjustment of the assessment period to take into account an interrupted career pattern;
- an electronic copy (pdf) of each of the five most significant publications (selected from within the assessment period);
- a clear statement of how much of any joint work is due to the candidate;
- names of two persons willing to act as referees, though the judging panel may approach referees other than those nominated;
- the referees should be chosen carefully; in particular, they should not have a conflict of interest and they should be able to give scientific insight into the work to be assessed. It may be easier to avoid a conflict of interest by choosing international referees; and
- a citation, of maximum 40 words, summarizing the mathematical research underlying the application.

A judging panel will be appointed by the NZMS President, and the panel makes recommendations to the President for the Award. No person shall receive the Award more than once. The Award consists of a certificate including an appropriate citation of the awardee's work, and will be announced and presented at the New Zealand Mathematics Colloquium Dinner in December.

All nominations and applications should be sent by email to the NZMS President, Assoc Prof Vivien Kirk by 31 August 2019. Submissions should state clearly that they are for the NZMS Research Award.

Unsuccessful applicants from 2018 will be invited to update their application so that it can be reconsidered in 2019.

The Research Award for 2018 was presented at the NZ Mathematics Colloquium dinner in Dunedin jointly to **Alex James** (University of Canterbury) for "her contributions in mathematical modelling ranging from the theoretical, such as Lévy walks and complex ecological systems, to the very applied, such as masting and snail dynamics" and **Carlo Laing** (Massey University) for "his sustained contributions to the field of mathematical neuroscience, and pioneering work in the study of coupled oscillator networks".

## NZMS Early Career Research Award

This award was instituted in 2006 to foster mathematical research in New Zealand and to recognise excellent research carried out by early-career New Zealand mathematicians. Applicants should be within seven years of confirmation of PhD, but an appropriate adjustment to this time period can be made to take into account an interrupted career pattern. Candidates may contact the NZMS President in confidence for clarification of how the adjustment of time period applies to the their particular circumstances. **The candidate will be judged on their best three published research outputs and a brief CV. Research outputs could include publications in books, journals, other peer-reviewed venues, or other types of high quality mathematical research.** To be eligible, the candidate must be a current member of the NZMS, and must have completed a significant part of their research in New Zealand.

Nominations and applications should include the following:

- name and affiliation of candidate;
- statement of general area of research;
- a brief CV which illustrates the nominee's standing in the community, including: any distinctions awarded, list of any graduate students supervised, list of any grants received (including names of co-investigators), full list of publications (including names of coauthors);
- if appropriate, a justification for an adjustment of time since confirmation of PhD;
- an electronic copy (pdf) of each of their three best papers (the papers must be published or in press);
- a clear statement of the mathematical contribution of the candidate in cases of joint authorship;
- names of two persons willing to act as referees, though the judging panel may approach referees other than those nominated;
- the referees should be chosen carefully; in particular, they should not have a conflict of interest and they should be able to give scientific insight into the work to be assessed. It may be easier to avoid a conflict of interest by choosing international referees; and
- a citation, of maximum 40 words, summarising the mathematical research underlying the application (it is recommended that self-applicants approach a colleague to write this citation).

A judging panel will be appointed by the NZMS President, and makes recommendations to the President for the Award. No person shall receive the Award more than once. The Award consists of a certificate including an appropriate citation of the awardee's work, and will be announced and presented at the New Zealand Mathematics Colloquium Dinner in December.

All nominations and applications should be sent by email to the NZMS President, Assoc Prof Vivien Kirk by 31 August 2019. Submissions should state clearly that they are for the NZMS Early Career Award.

Unsuccessful applicants from 2018 who are still eligible in 2019 will be invited to update their application so that it can be reconsidered in 2019.

The Early Career Award for 2018 was presented at the NZ Mathematics Colloquium dinner in Dunedin to **Fabien Montiel** (University of Otago) for "outstanding contributions to the development of mathematical and computational methods in wave scattering theory and his innovative approach to modelling the propagation of ocean waves in ice-covered seas".

## Kalman Prize for Best Paper

The Kalman Prize for Best Paper was instituted in 2016 to recognise excellence in research carried out by New Zealand mathematicians. The Prize will normally be awarded annually for an outstanding and innovative piece of research in the mathematical sciences published by a member or members of the NZMS. **The Prize is for a single publication of original research, which may be an article, monograph or book, having appeared within the last 5 calendar years: 2014-2018.** The value of the Prize is $5000. The Prize is generously funded by the Margaret and John Kalman Charitable Trust, and recognises the significant contributions to mathematics in New Zealand made by Professor John Kalman.

A publication may be nominated for the Prize by any member of the NZMS who is not an author of that publication. To be eligible, the nominated publication must have at least one author who:

i) is a current member of the NZMS, and was a member in the calendar year of publication of the nominated work; and |

ii) is a resident of New Zealand, and was a resident of New Zealand at the time when the research was carried out. |

In the case of publications with multiple eligible authors, the Prize will be shared by all eligible authors. The existence of authors who do not meet the conditions in i) and ii) above will not preclude the award, although the judging panel may take into account whether the NZ author has made a major contribution to the published work. The judging panel may deem a publication ineligible if an author has previously received an award from the NZMS for a body of research that included the nominated publication.

A judging panel will be appointed by the NZMS President, and makes recommendations to the President for the Prize. The winner of the prize will be announced at the New Zealand Mathematics Colloquium Dinner in December.

Each author of the publication should provide a CV including: distinctions awarded, full list of graduate students supervised, full list of grants received (including names of co-investigators), full list of publications (including names of coauthors).

Nominators should provide a brief summary of 1-2 pages of what makes the nominated publication important, innovative and outstanding (with appropriate references to prior or subsequent work in the field), and the names of three possible assessors. The judging panel may approach assessors other than those nominated. Assessors should not have a conflict of interest and they should be able to give scientific insight into the work to be assessed. It may be easier to avoid a conflict of interest by choosing international assessors.

All nominations should be sent by email to the NZMS President, Assoc Prof Vivien Kirk by 31 August 2019. Submissions should state clearly that they are for the Kalman Prize for Best Paper.

Unsuccessful applicants from 2018 (whose publication remains within the eligibility period) will be invited to update their application so that it can be reconsidered in 2019.

The Kalman Prize for Best Paper in 2018 was awarded to **Noam Greenberg** (Victoria University Wellington), **Andre Nies** (University of Auckland) and **Dan Turetsky** (Victoria University Wellington) for their journal article

## NZMS Aitken Prize (Student Prize)

The Society offers a prize for the best contributed talk by a student at the annual New Zealand Mathematics Colloquium. This prize is known as the Aitken Prize, in honour of the New Zealand born mathematician Alexander Craig Aitken. The Prize was first offered at the 1995 Colloquium held in conjunction with the Aitken Centenary Conference at the University of Otago. Candidates for the Prize give a talk on a topic in any branch of the mathematical sciences.

To be eligible, a candidate must be enrolled (or have been enrolled) for a degree in Mathematics at a university or other tertiary institution in New Zealand in the year of the award. The prize consists of NZ$500, accompanied by a certificate. Candidates should indicate their willingness to be considered for the Prize on the Colloquium registration form.

A judging panel is appointed by the NZMS President. The panel makes recommendations to the President for the Prize. Normally the Prize will be awarded to one person, but in exceptional circumstances the Prize may be shared, or no prize may be awarded.

The winner in 2018 was **Pascal Eun Sig Cheon** (University of Auckland) for the talk "Domain truncation in pipeline monitoring problems".

The prize consists of a cheque for NZ$500, accompanied by a certificate.
