Computational Neuroscience, Graph Neural Networks, Computer Vision

Biography

I am currently a PhD candidate in the Faculty of Engineering and IT at the University of Melbourne under Prof. Andrew Zalesky, Dr. Sidhant Chopra, A/Prof. Maria Di Biase, Dr. Wei Tong,and Dr. Lukas Roell, specializing in mathematical modelling, computational methods, and artificial intelligence, particularly computer vision, with applications to multiscale network modelling in neuroscience.

I have experience working in AI research at the Walter and Eliza Hall Institute of Medical Research as a Data Research Engineer, and at Sindy Lab as a Software Engineer focused on AI detection for academic integrity. I am also a teaching associate for Algorithms and Analysis at RMIT University and Algorithms for Bioinformatics at The University of Melbourne.
