Hi, I’m Polina.

I work at the intersection of responsible AI, human behavior, and technology.

I’m interested in what happens between humans and AI — how we understand it, trust it, evaluate it, and learn to use it responsibly.

How I got here

  • I have a Master’s degree in Psychology, which gave me a foundation in human behavior, cognition, learning, and how people understand and interact with the world around them.
  • I spent more than 4 years working in product and UX, including user research and product design. That taught me how technology is built around human needs — and how design decisions can shape behavior, expectations, and experiences.
  • As more of the products I worked with became AI-driven, I moved into AI evaluation and quality assurance. Working directly with AI systems showed me how much human judgment, ambiguity, and invisible labor sits behind model performance.
  • That experience pushed me to look beyond individual products and learn more about responsible AI, technology ethics, governance, and the broader relationship between people and increasingly capable AI systems. This eventually brought me to Stanford’s Ethics, Technology, and Public Policy program and to the work I’m doing today.
