    <h2>Bio</h2>
    <p>I am an Assistant Professor in the Department of Information Systems and Quantitative Analysis (ISQA) at the College of Information Science & Technology, University of Nebraska at Omaha. Before joining UNO, I served as an Assistant Research Professor in the College of Information Sciences and Technology at Penn State University. I earned my Ph.D. from the University of Pittsburgh in 2019. </p>

    <p>My research agenda is centered on advancing both our understanding of—and our ability to design—sociotechnical systems by applying methodologies from Human-Computer Interaction (HCI) and Human-Centered Computing (HCC). Positioned at the intersection of HCI, Intelligent User Interfaces (IUI), and Artificial Intelligence (AI), I focus on creating AI-driven systems that are fair, trustworthy, and transparent. To achieve this, I adopt mixed quantitative and qualitative methods—combining large-scale data analysis with narrative interviews, thematic analysis, and content analysis—to capture users’ needs, behaviors, perceptions, and practices across diverse contexts such as recommender systems, educational platforms, health-care technologies, and social media communities.</p>
