About Me

I am an AI researcher and engineer based in London, with an MSc in Machine Learning from University College London, awarded with distinction, and a BSc in Computer Science from NYU Abu Dhabi. My work has been published in ACM Computing Surveys and ACL SRW.

I am currently most interested in studying and mitigating demographic bias in machine learning models, and in the growing presence of AI in mental health and well-being.

Research Interests

Broadly, I am interested in the social consequences of AI systems. I also work on technical questions in interpretability, memory, and representation. Please feel free to reach out if any of this resonates.

  • AI and Social Inequality: I am interested in measuring how language and vision models respond to a person's identity, whether stated or inferred from how they communicate or appear, and how this shapes the information and decisions they receive.
  • Help-Seeking and Conversational AI: People are increasingly turning to LLMs for companionship, emotional support, and medical advice. I am interested in whose idea of care these models are built around, whether they tell people what they want to hear (i.e. sycophancy), and what that reliance displaces.
  • AI Safety and Interpretability: I am interested in mechanistic interpretability, and have worked on the faithfulness of sparse autoencoders. More broadly, I am interested in the role interpretability can play in detecting and mitigating misalignment.
  • Memory in AI Agents: I am interested in the retrieval architectures that keep agents coherent and factually consistent over long interactions, especially as they are deployed in more sensitive settings.
  • Graph Neural Networks: I am interested in solutions that leverage graph neural networks (GNNs) to model data with inherent graph-like structures. My research investigates the use of GNNs in advancing integrated circuit design, reliability, and security.

  2. Across seven language models, sparse autoencoders trained on the model’s own generated data (Faithful) have a lower fake feature ratio than those trained on Pile or Fineweb for GPT2-small, Gemma 2B and LLaMA 1B, 3B and 8B, but not for Pythia 1.4B or 2.8B.
