About Mariya Vasileva

My name is Mariya, and I work at the intersection of generative models, multimodal learning, vision–language systems, and safety and alignment. My research focuses on vision and language learning in large-scale multimodal models, with an emphasis on visual reasoning and evaluation science for frontier systems. In particular, my work tightly integrates vision–language model development — representation learning, modality alignment, posttraining, and synthetic data — with benchmark design, interpretability, and capability, alignment, and safety evaluations. A unifying theme of my work is multimodal safety, trust, and alignment, studied empirically through scalable oversight, stress-testing, and robustness analysis across the full model lifecycle.I spent a number of years in industry research and worked on a range of problems, from image and video generative models, to visual recommender engines, to 2D-to-3D human body shape and pose modelling, to synthetic data generation for efficient training of foundation models at scale, to fairness and explainability of AI systems. I obtained my PhD in Computer Science from the University of Illinois at Urbana-Champaign under the advisorship of professor David A. Forsyth, where I researched problems in vision and language, visual search and retrieval, and applications of computer vision in the fashion domain.

Experience

  1. Senior Research Scientist

    Meta

    Mar 2025 — Present · New York, NY, US

    Designed and implemented rigorous, large-scale evaluation frameworks for AI trust, safety, and alignment with a focus on systematic benchmarking, quantitative risk assessment, and scalable oversight of multimodal foundation and frontier models across high-impact domains- Developed core components of end-to-end scalable evaluation ecosystems spanning policy operationalization, large-scale vision data sourcing and annotation workflows, LLM/VLLM-as-a-judge framework development and calibration against human baselines, and risk metric design and instrumentation, enabling continuous oversight of model behavior in close collaboration with cross-functional partners; these evaluation frameworks now underpin all MSL pre-release model and product testing
