Thuany Costa de Lima

PhD Candidate

I am a geophysicist mostly interested in global observational seismology. I investigate the structure of the deep Earth through seismic waves. My Ph.D. research involves the development and application of different techniques to image the Earth’s interior, from the inner core to the mantle.

Previously to embracing seismology, I was interested in correlating multiple geophysical observations to the structural geology of cratonic sedimentary basins and reconstruct the history of crustal deformation. I had worked with gravity and magnetic geophysical data processing, interpretation of seismic reflection data, remote sensing, and structural geology.

Since 2018: PhD student in Seismology, RSES, The Australian National University, Australia.

2013 - 2015: MPhil in Geophysics. Universidade Federal do Rio Grande do Norte, Brazil.

2009 - 2012: BSc in Geophysics. Universidade Federal do Rio Grande do Norte, Brazil.

Before starting my Ph.D., I spent almost a year working as a private tutor, and teaching maths and physics to kids from Years 7 to 12. Currently, I am one of the volunteer mentors in the Girls Educating Girls program which is a project that aims to provide research experience for women enrolled in STEM fields at universities across Puerto Rico.

Part of the (160) undergraduate students participating in the Blue Planet field trip to the Snowy Mountains! Everyone had a wonderful time looking at the rocks and correlating what they have learned in the classroom with their observations on the field. Thanks to Tiah Penny for the selfie :D
