Tim Molteno presents Steve Rawlins Lecture

 

Tim Molteno presented the prestigious Steve Rawlings Lecture, on “The Transient Array Radio Telescope, at the South African Radio Astronomy Observatory postgraduate conference 2024.

Tim is known for his innovative work in radio astronomy, particularly the development of the Transient Array Radio Telescope (TART). This low-cost, open-source telescope is designed to detect transient radio phenomena and is notable for its accessibility, using off-the-shelf components to create an advanced interferometer.  

Congratulations Tim!

Sciences Divisional Awards 2024

Congratulations to Blair Blakie and Hannah Kasenich for their divisional awards 2024!

Outstanding Researcher

Professor Blair Blakie, Department of Physics

Professor Blair Blakie is a globally recognised leader in theoretical condensed matter physics, known for his groundbreaking research in ultra-cold atomic systems. His recent work on dipolar supersolids has advanced our understanding of their characteristics and confirmed earlier predictions about quantum droplets in collaboration with an international experimental team. This work is published in the leading physics journal, Physical Review Letters. Blair has six Marsden grants, and his contributions have attracted significant attention, including an invitation to speak at Harvard University last year. While serving as Head of Department, Blair continues to advance the frontiers of theoretical physics and he’s committed to nurturing the next generation of scientists, both which underscore his invaluable contributions to the academic community.

Best Research Paper (Postgraduate): Fundamental

Hannah Kessenich, Department of Physics

Hannah Kessenich’s research on the Antarctic ozone hole has made a significant impact in atmospheric science, that attracted widespread media attention. Her groundbreaking paper that was part of her PhD, reveals that despite the Montreal Protocol reducing the use of ozone depleting substances, the ozone hole has grown larger and deeper since 2004, contradicting expectations of recovery. Her analysis shows the hole has been among the largest on record over the period 2020-2022, with significantly less ozone in the centre during mid-spring. Hannah’s careful work challenges prevailing assumptions and provides crucial insights into the complexities of stratospheric dynamics and environmental policy. Published in the journal Nature Communications, the paper received considerable international media attention from CNN to the ODT, and Hannah was interviewed by several outlets including morning TV news shows.

Petra Fisher awarded Woolf Fisher Scholarship

Petra Fisher, Physics BSc (Hons) student at Otago, is one of four Woolf Fisher Trust scholarship awardees for New Zealand in 2025. The prestigious scholarship will fund Petra’s doctoral research at the University of Cambridge. 

Petra’s PhD research in physics will explore astrophysical fluid dynamics associated with the formation and dynamics of galaxies and accretion discs. 

Petra has already had a distinguished career at Otago, gaining Beverly Bursaries (2021,2023,2024), and a University of Otago Prestige Scholarship in Science (2023).

Congratulations Petra!  We wish you all the best for your doctoral studies, and will be keenly following what you do next.

Sir Michael Berry: James and Jean Davis Prestigious Visitor of the University of Otago

Sir Michael Berry, distinguished British physicist, renowned for his groundbreaking contributions to the field of quantum mechanics and wave phenomena has visited New Zealand as a James and Jean Davis Prestigious Visitor of the University of Otago.

Professor Berry’s work has had profound implications in various disciplines, including optics and condensed matter physics. He is perhaps best known for formulating the Berry phase, a fundamental concept in quantum mechanics that describes how the phase of a quantum state evolves when the system is adiabatically transported around a closed path in parameter space. This concept has not only enriched theoretical physics but has also found applications in areas such as molecular dynamics, quantum computing, and materials science.
