I am a Research Fellow at the University of Oxford, working with ʻŌiwi Parker Jones and Philip Torr. I am also a member of the ELLIS Society. I am passionate about advancing multimodal machine learning by creating models that are adaptable and trustworthy.

I earned my PhD in Artificial Intelligence at the University of Amsterdam, advised by Maarten de Rijke and Paul Groth. Before that, I obtained a MSc in AI from KU Leuven where I was advised by Marie-Francine Moens.

During my academic journey, I spent time at Microsoft Research, the Gemini team, Bloomberg AI, Amazon Science, LIIR at KU Leuven, and ETH Zurich as an intern. Alongside my research, I hold leadership roles in initiatives focused on diversity and inclusion in machine learning, including organizing the WiML Mentorship Program, serving as General Chair of WiML at ICML 2025, and mentoring through the ELLIS Inclusive AI initiative.

BarPlotsUniverse Adapting Vision-Language Models for Evaluating World Models.
Mariya Hendriksen, Tabish Rashid, David Bignell, Raluca Georgescu, Abdelhak Lemkhenter, Katja Hoffman, Sam Devlin*, Sarah Parisot*
Oral at NeurIPS LAW 2025; Under submission

We focus on the challenge of automated evaluation for world model rollouts and introduce a structured semantic protocol for this domain. We also propose UNIVERSE, a method for efficient adaptation of VLMs to this scenario.

VennDiagram Demonstrating and Reducing Shortcuts in Vision-Language Representation Learning.
Maurits Bleeker*, Mariya Hendriksen*, Andrew Yates, Maarten de Rijke
TMLR, 2024
arXiv / bibtex / GitHub

We propose a framework to examine the shortcut learning problem in the context of Vision-Language contrastive representation learning with multiple captions per image. We show how this problem can be partially mitigated using a form of text reconstruction and implicit feature modification.

VennDiagram Multimodal Learned Sparse Retrieval with Probabilistic Expansion Control.

We propose a framework for multimodal learned sparse retrieval.
