Rate My Professor Ray Marx

Ray Marx, holding a BSc and MSc from the University of Otago, has been a dedicated member of the Department of Geology staff since the mid-2000s. His MSc thesis, completed in 2004 and titled 'The evolution of Lake Rotorua,' examined the sedimentology and allostratigraphy of post-240 ka to pre-Waimihia Tephras (~26 ka) sediments underlying northern Lake Rotorua in the Rotorua Volcanic Centre, New Zealand. This work contributed to understanding volcanic and sedimentary processes in the region and led to a related publication in 2009 on the same topic. Earlier, in 2002, Marx received the Geological Society of New Zealand Postgraduate Prize, recognizing his postgraduate research excellence among students from multiple New Zealand universities. He co-authored 'Phytolith morphology and biogenic silica concentrations and abundance in leaves of Chionochloa (Danthonieae) and Festuca (Poeae) in New Zealand,' published in the New Zealand Journal of Botany (Volume 42, Issue 4, 2004), which analyzed phytolith types, silica content, and their ecological implications in native grasses. Marx has presented research at conferences, including abstracts on tephra beds in upper Miocene sediments (Geological Society of New Zealand, Tauranga 2007) and other geological topics (Oamaru 2009).

Currently serving as Safety Officer, Laboratory Manager, and Field Coordinator in the Department of Geology at the University of Otago, Ray Marx also acts as the Department Health and Safety Officer (DHSO). In this capacity, he oversees the implementation of the Health and Safety at Work Act 2015, manages hazardous substances in laboratories, and ensures compliance with safety policies. He coordinates field trips, provides logistical support including letters of introduction for landowners, and maintains resources such as plastic bags and other materials for fieldwork. Marx manages laboratory operations, including the Otago Paleomagnetic Research Facility, rock catalogues, fossil storage, and physical geology labs. His contributions are frequently acknowledged in student theses and research papers for assistance with fieldwork, sample preparation, XRF analysis, and logistical support—examples include petrology studies of metabasalts (Fagereng 2010), bedrock geology of the DFDP-2B drill core at the Alpine Fault (Toy 2017), magnetostratigraphy of OREP-1 drill core, and investigations into shallow intrusion explosivity. Through these roles, Marx supports teaching, research, and safe practices in geological sciences at the University of Otago.
