UX Research

I’m excited about the potential of technological innovations and novel interaction paradigms. I thrive in conceptual and strategic UX projects that consider interactions beyond a graphical interface. There is more to outstanding user interfaces than pixel-perfect aesthetics. My data-driven approach considers the user’s context, goals, perceptions, emotions, and expectations. Humans and computers function so differently that the translation between them needs a deep understanding of both.

A new generation of devices and tools will soon redefine how we engage with virtuality, data, and computing systems. I’m thinking of AI in all kinds of flavors, virtual and mixed reality (XR), embedded systems, ambient computing, proactive agents, and biometrics. As users, we can look forward to more natural interactions, such as conversational interfaces with natural language, eye tracking, 3D and gestural interactions, haptic feedback, neural interfaces, and multimodal systems.

Virtual space will soon be seamlessly integrated into our personal and professional lives, just as laptops and smartphones are today. It doesn’t have to be a spooky dystopia – it’s an opportunity! This tech landscape on the horizon needs UX experts who see the whole picture, introduce original interaction techniques, and offer creative and ethical solutions based on user research and tech literacy, building trust and value.

In my work, I design the interactions between people and this new generation of technology to empower users. Let’s create ubiquitous availability of virtuality rather than intrusive distraction. Let’s strive to enrich the user’s world in meaningful and helpful ways instead of cluttering it with digital content. I imagine seamless integration of the virtual into the real, where interaction feels like engaging with the world naturally, not like operating a system. I want to shape this paradigm shift for the better.

My research focus

  • Human-computer interaction (HCI)
    and user experience (UX)
  • Virtual reality (VR), blended realities (XR)
    3D interactions and spatial computing
  • Conversational interfaces and
    artificial intelligence (AI)
  • Aspects of fidelity and realism
  • Object manipulation and haptics
  • Embodiment and avatars

Dissertation

In 2024, I published and defended my doctoral dissertation entitled “Unraveling the Fidelity of Virtual Reality Interactions: Effects of Realism in Object Manipulation and Embodiment.” You can read more about my thesis – in easy language or in technical terms – and get the free download of the open-access document.
