Dr. Jonathan Tyler is an Associate Professor in Earth Sciences with a PhD from University College London and research experience from the Universities of Tokyo, Oxford and Melbourne. His teaching and research revolve around climate variability past and present and the way Earth surface processes can be deciphered using chemical signatures. When not working, Jonathan is being re-educated about the world via his three children. He tries to spend as much time as he can outside, but otherwise indulges in following the travails of the English cricket team whilst listening to '90s alternative rock.
I am a palaeoclimatologist and isotope geochemist. That means I am interested in past climates and the use of chemical tracers in sediments to develop our understanding of past climate changes. I mostly work with lake sediments, but also work in terrestrial, marine, estuarine and cave environments.
Mainly, I am interested in developing isotope-based tools for quantifying past climate variability. This involves field and experimental studies on modern systems. I then apply these techniques to examine the patterns and causes of past climate change, in regions as diverse as coastal Antarctica, central Australia and Japan. In 2024 I will start an ARC Future Fellowship, which aims to better understand climate variability in southern Australia through the last 2000 years, with a view to providing data and knowledge relevant to policy makers and environmental managers. Similarly, I am actively researching the interplay between climate variability and changing vegetation and fire regimes in order to better understand bushfire risks and mitigation strategies, most notably on Kangaroo Island, South Australia.
During my career I have worked with a variety of techniques, both geochemical and palaeoecological, including oxygen and silicon isotopes in biogenic silica, carbon and nitrogen isotope analysis of sedimentary chlorins and branched GDGTs as a proxy for surface air temperature and soil pH. Recent projects involve the use of 'clumped isotope' palaeothermometry and sub-annual geochemical analysis of fossil and modern bivalves. I've supervised over 30 Honours students, and over 10 PhD students and place a high value on mentorship and fostering an inclusive and positive research environment.

Earth Systems I (GEOLOGY 1103)
This course draws from all fields of geoscience to explore the evolution of Planet Earth. My lectures introduce students to the energy balance on Earth, the fundamentals of atmospheric and ocean circulation and their effects on the hydrosphere, cryosphere and biosphere.
Geochemistry II (GEOLOGY 2505)
This course focuses on the chemistry of the natural world and the chemical evolution of the Earth over geological time. I coordinate this course and my lectures include the partitioning of elements on Earth, low temperature geochemical processes and the fundamentals of stable isotope geochemistry.
Earth Systems History III (GEOLOGY 3505)
This course focuses on the chemistry of the natural world and the chemical evolution of the Earth over geological time. I coordinate this course and my lectures primarily cover climate variability during the late Cenozoic and Quaternary up to present day, including the various techniques used to reconstruct climate change over those timescales.
Structural Geology II (GEOLOGY 2501)
This year (in 2016) I'll be joining my first Pichi Richi field camp with Structural Geology. I'm really looking forward to spending a week out in the Flinders Ranges, and being part of one of Adelaide's longest running geology traditions.
Principles and Practice of Research II and III (SCIENCE 2300 and 3100)
I regularly contribute to the PPR courses for the BSc Advanced program, leading tutorials and supervising research projects.
