Rate My Professor Timothy Marshall

Timothy Marshall serves as a laboratory technician in the Department of Physics at the University of Otago in Dunedin, New Zealand. His professional contact information includes the direct dial number +64 3 556 5330 and email timothy.marshall@otago.ac.nz, as listed on the university's official department contact page. Marshall holds a Bachelor of Applied Science in Energy Management and Physics from the University of Otago, completed between 2012 and 2014. He further obtained a Master of Teaching and Learning in Secondary Education from the same institution in 2015 and a New Zealand Diploma in Engineering Mechanical from Otago Polytechnic in 2018. These qualifications support his technical expertise in areas such as mechanical engineering design, applied thermodynamics, AutoCAD, Solidworks, and secondary education.

Marshall has actively contributed to research initiatives within the Department of Physics. During the 2013/14 summer period, he participated as a fellowship student in the Space Physics Group at the University of Otago. He is a co-author of the 2015 publication titled 'A quantitative examination of lightning as a predictor of peak wind gusts in supercell thunderstorms,' published in the Journal of Geophysical Research: Atmospheres, where his affiliation is noted as the Department of Physics, University of Otago. In the summer of 2018-19, Marshall collaborated as a summer student with Dr. Harald Schwefel and the Dodd-Walls Centre Industry team, including Luke Taylor, to develop six prototype handheld lamps replicating the flickering torchlight used by Paleolithic cave artists. These lamps featured hand-blown glass elements, stone-mimicking bodies sourced from various regions, and three LED lights calibrated to the sodium emission line identified through spectral analysis of ancient residues. Adjustable via a button mechanism, the prototypes produced 13 distinct intensity and flicker patterns, achieved through experiments with wind effects and wick lengths to match archaeological specifications provided by Leslie van Gelder. The lamps were tested in an Australian cave, enhancing the visibility of ancient artworks through dynamic shadows and spectral colors, bridging quantum physics with archaeology. This interdisciplinary work provided hands-on experience in prototyping and light simulation technologies.
