I investigate the shifting relationship between essence and perception. My work begins from the idea that what we understand as reality is not fixed but constantly reconstructed through subjective interpretation, memory, context, and time. To visualize this process, I developed the Modulated Mold Casting technique, which allows multiple forms to emerge through the recombination of modular mold components. The resulting works are not representations of stable objects but material traces of transformation and difference. Through these forms, I seek to reveal perception as an ongoing process shaped by relational conditions rather than a singular, objective truth.
