Dr Denys Villa Gomez
Denys specialises in bioprocess engineering to recover resources from waste within the Synbio Group
Denys has contributed to expanding the knowledge of engineering approaches and biobased processes for the treatment and management of waste and resource recovery from urban and industrial waste and wastewater. Her research leans on applying biological processes such as biological sulphate reduction for making the treatment of waste more sustainable and economically viable by maximising the efficiency and decreasing the environmental footprint of the operations. For example, I lead projects on the recovery of cobalt and rare earth elements from mine impacted waters and tailings using biological processes. Recovery of these elements is a priority to Australia due to its low abundance and high demand worldwide, particularly in new technologies combating climate change. This has influenced the field nationally and internationally, as shown in her research metrics, conference invitations as a keynote speaker and as a member of international scientific committees. She is ranked No. 1 in Australia, and No. 11 worldwide in the SciVal topic “acid mine drainage; sulfate-reducing bacteria; sulphate”.
Denys Villa Gomez is an Advance Queensland Research Fellow at the Australian Institute for Bioengineering and Nanotechnology. She obtained her PhD at the world leading institute’s IHE-Delft/Wageningen University, The Netherlands in 2013. She applies advanced methodologies such as omics approaches and micro spectral tools to develop biotechnology processes that reduce pollution and recover resources such as energy and metals. Denys has published over 40 peer-reviewed journal and conference papers cited more than 400 times, has served as editor and reviewer for leading journals (e.g. Frontiers in Bioengineering & Biotechnology) and advisory roles in industry and scientific committees (e.g. International Mine Water Association). Villa Gomez has multiple research projects as chief investigator with industry, government, and academia, and with international and UQ-based researchers (over AU$2.5M), for example, the 3-year project with the Queensland government and Rio Tinto using synthetic biology to recover critical minerals.
