Iain Collings is a Professor in the School of Engineering, Macquarie University, Sydney, Australia, since 2014, where he has served terms as Head of Department and Deputy Dean of School. He received a PhD in systems engineering from the Australian National University in 1995. In between he spent nine years at the CSIRO, where he held a number of roles including Deputy Chief of Division, Research Program Leader, and Theme Leader, and nine years at the Universities of Melbourne and Sydney.

He is a Fellow of the IEEE, and has published over 300 papers in the area of wireless communications. He has been awarded:

* The Engineers Australia IREE Neville Thiele Award in 2009

* The IEEE CommSoc Stephen O. Rice Award in 2011

* While at CSIRO he was a memeber of a research team that was awarded the Chairman's Medal in 2012.

* Best Paper prizes at international conferences including IEEE Globecom 2010 and the Asia Pacific Communications Conference 2023

He has made pioneering contributions in adaptive multiple user and multiple antenna wireless communication systems. These are key technologies in all outdoor mobile and indoor wireless systems. His work spans fundamental research, prototype development, postgraduate teaching, and consulting. His contributions were essential for the development of high spectrum efficiency (MIMO) wireless communication systems, and he has made several fundamental contributions to practical transmitter and receiver system design.

In 2000 he co-founded the Australian Communications Theory Workshop (AusCTW), that has since been run 21 times over the past 24 years. He continues to lead the Steering Committee.

He is a member of the Australian Academy of Science National Committee for Information and Communication Sciences (NCICS). He is a member of the General Assessor Panel of the Australian Research Council (ARC) National Intelligence and Security Discovery Research Grant (NISDRG) Program. He is an Associate Editor for the journal Sensors, and has served as an Editor for IEEE Transactions on Wireless Communications.

He publishes research and education videos on a YouTube channel that has more than 80,000 subscribers and has been viewed over 7M times. It is ranked in the top 6% of all Australian channels, and in the top 8% of all Education channels globally.

He recently published an Engineering Education paper titled: "Online Delivery of Solutions-Based-Learning Focused Tools for Engineers with Global Impact" at the 33rd Australasian Association for Engineering Education (AAEE) Conference.
