Plant nutrition, specialising in tropical root crops.

Since joining the University of Queensland in 1992, Dr. O'Sullivan has completed a series of projects characterising deficiencies and toxicities of mineral nutrients, in species of sweetpotato, aroids and yams, and identifying and remediating nutritional disorders in semi-subsistence production contexts in collaboration with project partners in Pacific Island countries.

Research Interests

  • Population growth and its impacts
    The environmental, social, micro- and macro-economic impacts of population growth, and the efficacy of policy and program options addressing it.
  • Demographic ageing
    Critiquing the basis and motives for negative messaging about demographic ageing and advancing more objective and balanced analysis.
  • Carbon pricing as a response to climate change
    Advantages of consumption-basis accounting and charging for greenhouse gas emissions, and risks and misconceptions around emissions trading.
  • Food security
    Multidimensional challenges of meeting the food demands of the global population while preserving or restoring environmental function and biodiversity.
  • Crop Nutrition
    Mineral nutrient deficiencies and toxicities, particularly of tropical root crops.
  • Low input and semi-subsistence farming systems
    Improving productivity and sustainability of smallholder agriculture in the tropics.
