I am a Research Scientist at Pacific Northwest National Laboratory (PNNL). I received my Ph.D. in Computer Science and Engineering from University of South Florida.
Current Interests Foundation Models (Language + Multimodal), Geometric Deep Learning (Dynamic Graphs), Privacy and Security
We develop massive-scale, self-supervised, multimodal foundation models of scientific knowledge capable of general-purpose inferences to enable reasoning with existing knowledge and discovery of new knowledge across science and security domains. |

The objective of this work is to develop technologies for high-fidelity simulation of online social behavior (the spread and evolution of online information) while rigorously testing and measuring simulation accuracy |

The objective of this work is to provide big data owners with tools to safely share their social networks data with the research community. The project aims to approach graph anonymization via two techniques for graph generation: dK-series techniques, introduced in the context of internet network generation, and Exponential Random Graph Model-based approaches (ERGM). My contribution is related to privacy/ utility measures, and how such graph annonymization techniques could apply on evolving graphs. |
