Emanuel (Manny) Azcona
Emanuel is a Ph.D. candidate in Electrical Engineering and a senior member of the Image and Video Processing Lab (IVPL) at Northwestern University (NU), where he has also received an M.S. in Electrical Engineering. Prior to NU, he attended New York University (NYU), where he received his B.S. in Electrical Engineering, along with minors in Integrated Digital Media and Computer Science. His primary research interests are in graph representation learning for medical imaging, graph signal processing, and predictive modeling of human decision-making using heterogeneous multipartite graphs. Some of his prior work has analyzed 3D surface mesh representations of the human brain structures (cortical ribbon and subcortical nuclei) and utilized spectral graph neural networks (GNN) models for the in-vivo classification of Alzheimer’s disease (AD). In addition, he has also developed conditional generative GNN models that have been shown to generate brain structures whose shape may vary based on AD diagnosis. He is currently developing a hybrid AI framework that integrates latent cognitive features (such as loss aversion) from a behavioral framework known as Relative Preference Theory (RPT) and heterogeneous GNNs to predict human expressed behavior and/or decision-making.
