Hi, good to see you here! I’m a Master of Cognitive Science (Data Science spec.) student at Carleton University in Ottawa I’m researching the cognitive neuroscience of language at the L-Neuro Lab and computational models of cognition at ANIMUS Lab.

My current research studies how language-specific concepts are organized in the bilingual brain. I’m also studying whether multilingual LLMs form comparable representational structures. In particular:

• Whether semantic associations specific to one language transfer to another
• Whether similar interference affects how Transformer-based LMs encode concepts.

Meanwhile, I love doing reasearch in the industry. I’m passionate about bringing cognitive science to real life in the context of HCI, user research, and behavioural economics. Human factors are rarely considered but are essential for understanding the users, informing a business in its product design and customer engagement tactics. These are differentiating acumens that set a business apart in this AI hype. My current interests lie in human-AI interaction, consumer study, and decision-making biases. I’m ready to hop on a project so feel free to book a chat with me!
