Long Bio

Katerina is a graduate psychology student and a research assistant in the Learning Engineering Institute. She is passionate about helping students achieve their goals and find joy in learning. Her research focuses on developing educational technologies to assess and support students' comprehension of complex expository texts. Specifically, she is interested in using generative artificial intelligence, machine learning, natural language processing, and educational games to both gauge students’ comprehension skills and provide personalized strategy support. She is also interested in discovering more about how different aspects of knowledge and text relate to comprehension performance. Katerina has experience using a variety of tools and programs to support her research: Python, R, Javascript/CSS/HTML, SPSS, JASP, G*Power, Qualtrics, TAACO, Coh-Metrix, ChatGPT, Gemini, and Canva.

Research Activity

Active

ReQUESTA: Evaluating a multi-agent system that generates comprehension questions for expository texts. Developed an expert evaluation rubric, and currently comparing questions from ReQUESTA and base ChatGPT 5.0 to determine whether ReQUESTA represents an improvement in question quality.

AI-X Toolkit: Designing a toolkit to support novice creators of generative AI tools. Specifically focused on creating a set of resources to support, (1) exploring an educational challenge, (2) creating an AI tool, (3) implementing an AI tool, and (4) investigating the effectiveness of an AI tool in supporting user goals.
