Peru Bhardwaj is an Alexander von Humboldt Research Fellow at the University of Stuttgart, Germany. Her research lies at the intersection of Adversarial Machine Learning, Explainable AI, Natural Language Processing, and Knowledge Representation and Reasoning.

Prior to joining the University of Stuttgart, Peru completed her PhD from Trinity College Dublin, Ireland. Her thesis investigates the robustness of graph representation learning algorithms by designing adversarial attacks that lead to unintended predictions from the learned models. The focus of her thesis are Knowledge Graph Embedding (KGE) models that enable machine learning on large scale knowledge graphs through feature vector representations of entities and relations. These models are increasingly used in user facing applications in high-stake domains like healthcare and finance where motivated malicious actors can try to misuse them. Furthermore, the predictions of KGE models are non-interpretable and black-box in nature. Through methods that lead to KGE models’ failure (i.e. adversarial attacks), Peru's thesis aims to provide an understanding of the predictive behaviour of these models, as well as improve the utility of KGE models in user applications that require trustworthy predictions.
