Sol is a Ph.D. student advised by Prof. Sri Kurniawan (UCSC CM) and mentored by incoming Prof. Jas Brooks (MIT CSAIL) focusing on multisensory engineering and sensory accessibility. She has worked at CMU’s Entertainment Technology Center under the mentorship of Prof. Jessica Hammer and holds dual B.S. degrees in Food and Nutrition and Information and Interaction Design at Yonsei University.
Her interdisciplinary research explores the intersection of hedonic design, motivational interfaces, and flavor science. She enjoys extending scientific and computational theories into everyday objects.
Before academia, Sol was a biotech skincare developer — and her food-inspired works have been showcased at a major cosmetic conference.

In this work, we examine over 50,000 images across hyper-palatable, normal, and healthy categories to identify patterns in their visual composition—specifically saturation, color entropy, and spatial alignment—with computer vision and CIELAB color space.

We present a multisensory audio system with microencapsulated scent. As the user scratches or plays the record, surface friction activates localized scent release—coupling the tangible input with olfactory and low-quality audio output. This system explores how physical, auditory media can be reimagined as a tangible recollection.

Multisensory modalities were incorporated into a self-ordering kiosk used for daily food selection. Subsequently, we conducted an experiment to observe how participants perceived an unfamiliar food on a multisensory interface, and found them to exhibit a significantly increased willingness to try the food regardless of level of fear.

Scents can be used to augment games and playful technologies, enrich the play experience, and evoke specific emotional responses. However, scent can also serve as an effective storytelling tool by its very presence/ absence to be a game narrative mechanism. We present Scented Days, where we showcase the use of olfactory cues to deliver narrative elements.
Under Preparation
We present a compact, reversible heating and cooling platform to explore the surface sensory materiality of sugar glass. Our system uses a Peltier module for small-scale simulation of the hard candy pulling process— to surface-changing via thermodynamic transitions.

What will happen after I die? We hardly wonder about our Instagram account’s after death maybe because it is deemed less important, or is something that is valued less than physical connections. We investigate user identity on social media after demise and propose a system for shared commemoration on an existing platform.
