David Cohen

Qualifications

BSc (Hons), Sydney University, 1983

MSc, Queen's University Canada, 1986

PhD, UNSW, 1990

I am President of the UNSW Academic Board.  From 2008-2016 I was head of the School of Biological, Earth and Environmental Sciences and the Deputy President of the Academic Board. My main research interests are in geochemistry with a focus on exploration methods for mineral deposits. I have been involved in research projects in North America, Indonesia, Europe, PNG, Pakistan, Iran and, of course, Australia. I led the Geochemical Atlas of Cyprus. I am President of the Australian Geoscience Council.

Education

  • BSc 1983 (Sydney) in Geology
  • MSc 1986 (Queen’s) in Geochemistry
  • PhD 1990 (UNSW) in Geochemistry
  • FRSN, FAAG, FAIG, MAICD

RESEARCH

My Research Goals

Develop better methods of geochemical exploration, especially in areas containing deep cover.

Investigate the use of biogeochemistry and selective chemical extractions in both exploration and contaminant detection.

Implement regional geochemical mapping programs in various parts of the world.

Evaluate various approaches to processing geochemical data with a view to separating "signals" related to either the effects of mineralisation or contamination from other processes or effects.

My Research in Detail

My research group examines the relationships between the geochemical characteristics of the surficial environment (soils, sediments, vegetation) and parent material, with a focus on the development of geochemical methods suited to mineral exploration in a variety of environments. This extends from mapping and trying to understand geochemical patterns in various sampling media at scales ranging from mineral deposits to entire countries.

    Supervision Opportunities/Areas

    Ongoing analysis of the very large set of soil samples collected as part of the Cyprus Atlas project.

    Geochemical dispersion in the weathered zone for a range of mineral deposits in various landscapes from the arid to the tropical.

    Mapping urban metal contamination.

    Otherwise.... come and talk to me about projects you would be interested in undertaking!  UNSW does have a large array of analytical facilities.

    Advice for prospective students

    PhD or MPhil students should think about the research topic that you would like to undertake and then talk to me or others in the group about details. In essence it is your project to design, implement, present (at conferences) and write up. For BSc(hons) students we can provide more assistance with things.

    Whereas I have supervised a number of different styles of project over the years, my preference is probably a project that gets you into the field (especially in remote and interesting localities).
