Gabriella Alodia is a PhD graduate from the School of Earth and Environment, University of Leeds. Her primary interest is marine geophysical data acquisition and processing, ranging from sonar-based techniques (singlebeam and multibeam echosounder, side-scan sonar, sub-bottom profiler) to potential field-based techniques (marine gravity and magnetic) for high seas and deep-sea geoscience research. During her PhD, she has developed a geomorphometric algorithm to automate crustal type classification, specifically at slow-spreading ridge environment. She has has also been involved as Early Career Scientist (specifically in geophysics) aboard international and national research cruises.
