Modelling Qualia with Physical Computers
2024

I argued that Jackson’s knowledge argument about qualia does not refute physicalism: even purely physical computational systems can fail to predict their own sensory information if they have the right structure and complexity, providing a physicalist and computationalist explanation of qualia.

Empirical Constraints and the Computational Unpredictability of Physical Systems
2024 · Doctoral Dissertation

In my doctoral dissertation, I argued that if we take the physical Church–Turing thesis seriously as an empirical claim, then time-constrained physical systems face a fundamental limitation: they cannot predict their own computational outcomes, which has implications for understanding free will, Kalmár’s objection to Church’s thesis, and the nature of qualia.

The Physical Church–Turing Thesis and the Halting Problem
2022

I investigated whether the physical Church–Turing thesis and the uncomputability of the halting problem can consistently coexist, examining Seth Lloyd’s argument that physical systems characterized by the PCTT are inherently unpredictable in their decisions.

HeroMirror Interactive: A Gesture Controlled Augmented Reality Gaming Experience
2019

We built an augmented reality quiz game where players interact through hand gestures recognized by a deep learning model using a regular camera — no depth sensor needed. The system was presented as an interactive kiosk featuring a virtual “hero” character who guides the player through the experience.
