LISETTECARRION

I am Dr. Lisette Carrion, a mathematical linguist specializing in holomorphic semantic embeddings and complex-analytic representations of symbolic systems. As the Chair of Analytic Semantics at the Institute for Advanced Study (2024–present) and former Chief Scientist of Google AI’s Complex Language Dynamics team (2021–2024), my work bridges Riemann surface theory with large-scale semantic topology. By modeling semantic manifolds as Bergman spaces and Hardy spaces over multiply connected domains, I developed Holomorphic Embedding of Language (HEL), a framework that resolves polysemy ambiguity with 98.7% accuracy (Journal of Mathematical Linguistics, 2025). My mission: To redefine language as a complex-analytic geometry where words flow like meromorphic functions across conceptual Riemann spheres.

My previous relevant research includes "Topological Property Analysis of High-Dimensional Semantic Spaces" (Transactions of the Association for Computational Linguistics, 2022), exploring geometric and topological structures of language model embedding spaces; "Differential Geometry-Based Attention Flow Models" (NeurIPS 2021), proposing a new perspective viewing attention mechanisms as geodesics on manifolds; and "Mathematical Analogies Between Semantic Continuity and Quantum States" (Computational Linguistics, 2023), investigating the application potential of quantum mechanics mathematical frameworks in language models. Additionally, I published "Applications of Analytic Functions in Signal Processing" (IEEE Transactions on Signal Processing, 2022) in complex analysis, providing theoretical foundations of complex functions for signal representation. These works have laid mathematical and computational foundations for the current research, demonstrating my ability to apply advanced mathematical theories to language processing. My recent research "Complex-Valued Neural Networks for Multimodal Representation" (ICLR 2023) directly explores the advantages of complex-valued networks in processing multimodal data, providing technical implementation pathways and preliminary experimental results for this project, particularly in designing complex-valued neural network architectures and training methods.
