The CSIRO has tapped Brendan Dalton to be the research organisation's chief information officer.
Dalton has held a variety of IT leadership roles in the public sector, including CIO at the Clean Energy Regulator and the former Department of Climate Change and Energy Efficiency.
He was most recently assistant secretary at the immigration department.
The new CSIRO CIO officially commenced his new role on 6 July.
He will lead the CSIRO's Information Management and Technology (IM&T) team of 250 staff across 30 sites.
"I am excited to be taking on the role and want to build on the momentum that the CSIRO IM&T team has established over many years in supporting both corporate and research computing needs," Dalton said in a statement.
"The IM&T team has the ability to build some truly great national computing infrastructure and to support CSIRO’s reform journey through targeted information management solutions."
Dalton replaces acting CIO Euan Sangster. Sangster had been acting in the role for the last nine months.
