Senior Lecturer in the School of Civil and Environmental Engineering

Research interest

  • Investigate the implications of 3D kinematic datum modernisation for professional and mass market users, particularly in tectonically active environments.
  • Investigate the application of high precision multi-GNSS/ PPP positioning. Leveraging CORS infrastructure and combining UAV or laser scan data for practical application to surveying and geospatial engineering.
  • Understand the policy implications of new measurement technologies on authoritative geospatial data management (GPS for cadastral, DCDB, LandXML, eGeodesy, SUI standards, Dial before you dig, smartphone imagery etc).
  • Investigating AR/VR applications in Surveying and Geospatial Engineering

Interest in engineering

Why did you get into engineering?

I like geometry, maps and the outdoors and Surveying combines all three.

What are your research goals?

To modernise the national/ international datum and map the geophysical changes that we can now measure in 4D. To better understand multi-GNSS positioning and augmentations. To develop governance to better map underground utilities in accordance with GDA2020 and AS5488 Subsurface utility standard.

What do people not understand about you do?

People trust their modern devices to give them the correct positions all the time. Measurement science is far more complex and expectations of accuracy nowadays are sometimes unrealistic.

Advice for prospective Surveying and Geospatial engineers

Love maths (especially geometry – do Maths Ext 1). Love maps. Love gadgets. Be precise. Love the outdoors.
