Doctor Yolima Carrillo

KEYWORDS: soil carbon, nutrient cycling, rhizosphere processes, elevated CO2, drought, soil organic matter


Doctor Yolima Carrillo is a Senior Lecturer in the Institute. Her research focuses on the cycles of carbon and nutrients in terrestrial ecosystems, both natural and agricultural. She is interested in the mechanisms by which these cycles are affected by environmental change and management. She studies belowground biogeochemical processes and how they are shaped by plants, plant roots and soil biotic communities.

Biographical details

Prior to joining HIE she worked as a Teaching and Research Fellow at the Department of Environmental Sciences, Faculty of Agriculture of the University of Sydney, which she joined after doing post-doctoral work at the University of Wyoming (USA). She obtained a PhD in Ecology at the University of Georgia (USA) where she also obtained a graduate certificate in Conservation Ecology. Dr Carrillo completed her undergraduate studies at the National University of Colombia

Research interests

Dr Carrillo combines field and laboratory experiments to answer questions at the ecosystem level at the plant-soil-microbe interface. As tools for her research she has used a variety of applications of stable isotope tracers of carbon, nitrogen and oxygen, microbial and whole soil community assessments as well as various chemical approaches to the analyses of pools an fluxes of carbon, nitrogen and other nutrients in plants, soil, soil microbes and the atmosphere.

Her current areas of interest include:

  • Rhizosphere mediation of soil organic matter dynamics, including decomposition and formation, as affected by climate change factors (including elevated CO2, warming and water stress)
  • Mechanisms of impact of water stress and water availability on carbon cycling, stoichiometric relations and microbial communities in soil and potential feedbacks to climate
  • Mediation by plant roots on plant water use and plant and microbes nitrogen uptake via impacts on the soil physical environment
  • Role of mycorrhizal symbionts on soil organic matter dynamics
  • Response of biogeochemical processes and microbial communities to ecosystem restoration

Teaching

She co-founded and also co-leads the Stable Isotope in Biosphere Systems, a multi-institutional intensive  8-day annual workshop directed at researchers of all levels seeking to enhance or bring stable isotope techniques to their work.

Awards and Recognition

  • Won a Western Sydney University Researcher Development Strategic Initiative Funding – Women’s Fellowship Scheme Award, 2015. The award supported her research project ‘Water and nitrogen in soil: are they a solid couple?’.
