Qualifications
PhD, 2011, The University of Sydney
B.Sc. (Advanced) Hons I, 2002, The University of Sydney

Background
After completing a Bachelor of Science degree in computer science at the University of Sydney, Ms. Ceguerra worked at IBM Australia as an application programmer for four years, before coming back to the University of Sydney for a PhD at the Australian Centre for Microscopy & Microanalysis (ACMM). During her PhD candidature, she studied and developed analysis techniques in atom probe tomography. She is currently a Postdoctoral Research Associate at the ACMM.

Research project
Dr. Ceguerra is working with Prof. Simon Ringer, and her project is in Modelling and Simulation Techniques for Atom Probe Microscopy (APM) Analysis. She is developing characterisation and simulation techniques to study the structural aspects of alloys at the atomistic level and at slightly higher length scales. These techniques will be used in the analysis of APM data.

Research Interests
Dr Ceguerra’s other research interests include computer science.
