Experience

Jun. 2025 - Aug. 2025
Research assistant
The University of Auckland
Auckland, New Zealand

I was hired under a short-term casual contract to finish the preparation of manuscripts on the phase resetting work I studied during my post-doctoral research fellowship.

May 2023 - May 2025
Postdoctoral research fellow
The University of Auckland
Auckland, New Zealand

I worked in the Department of Mathematics with Professors Bernd Krauskopf and Neil Broderick as part of the project "Quantum effects in coupled nano-lasers". Given a perturbation into a stable, pulsating laser system, the laser will initially exhibit some response to the perturbation, but will ultimately reset back to the stable oscillations. There will be, however, an induced phase difference relative to the unperturbed oscillations. Modelling the laser as a nonlinear dynamical system, I used numerical continuation techniques to study the phase resetting of the stable oscillations or, periodic orbits in the Yamada model.

2017 - 2023
Graduate teaching assistant
The University of Auckland
Auckland, New Zealand
  • Marker and tutor for postgraduate courses on quantum mechanics and quantum optics.
  • Student coordinator for the Physics Tuākana program. I would organise tutorial times, assist the main coordinator with administration tasks, and attend monthly Faculty meetings with other departments.
  • Tutor for the Physics Tuākana drop in tutorials for Māori and Pasifika students. I would help students from all stages of physics with concepts from their classes, their assignments, as well as test preparation.
  • Lab demonstrator for the Stage II and III laboratory students. This involves helping students with the experimental equipment and theory and marking reports and providing feedback.
  • Marking tests and assignments as well test invigilating for Physics 107 - Planets, Stars and Galaxies.
2016 - 2023
Volunteer karate instructor
Fushin Ryu Karate Assoication
Auckland, New Zealand

I taught two - four classes a week to children from ages 6 to 16 as well as two classes of adults. I am responsible for teaching the students new techniques and abilities as well as strengthening current ones.

Education

2019 - 2024
New Zealand Diploma in Te Reo Māori (Māori Language)
Te Wānanga o Aotearoa
Auckland, New Zealand

I learnt Te Reo Māori (the Māori language) in a series of year-long rūmaki reo (full immersion) coures, achieving the following certifications:

  • New Zealand Diploma in Te Reo Māori (Rumaki) Level 7, Te Pīnakitangi ki te Reo Kairanga (2024)
  • New Zealand Diploma in Te Reo Māori (Rumaki) Level 6, Te Aupikitanga ki te Reo Kairanga (2023)
  • New Zealand Diploma in Te Reo Māori (Rumaki) Level 5, Te Rōnakitanga ki te Reo Kairanga (2022)
  • New Zealand Certificate in Te Reo Māori (Rumaki) Levels 3-4, Te Ara Reo Māori: He Pī Ka Rere (2021)
  • New Zealand Certificate in Te Reo Māori (Rumaki) Levels 1-2, Te Ara Reo Māori: He Pī Ka Pao (2020)

2023
PhD. in Physics
The University of Auckland
Auckland, New Zealand

Worked under Professor Howard Carmichael and Associate Professor Scott Parkins researching frequency filtering techniques in a quantum optics setting. We developed a theoretical model that allows an approximation of an ideal bandpass filter, allowing more accurate calculations of frequency-filtered photon correlations to be performed.

2019
MSc. in Physics
The University of Auckland
Auckland, New Zealand

For a year I worked under Professor Howard Carmichael investigating the fluorescence spectrum and photon-correlations of a driven three-level atom. An entire year's worth of directed research was presented in a thesis as part of the degree's requirements.

2018
BSc. (Hons.) in Physics
The University of Auckland
Auckland, New Zealand

Worked under Professor Howard Carmichael exploring the effects of spontaneous emission, quantum dephasing and thermal photons on the generation of sub-Poissonian light.

2017
BSc.
The University of Auckland
Auckland, New Zealand

Doubled major in Physics and Mathematics.
