01 About

I was born in Iowa, spent part of my childhood in New Zealand and Korea, and now call Fullerton, California home. Moving between places that early probably had more to do with why I like research than anything else — you notice pretty fast that the same question can look completely different depending on where you're standing, and I've been chasing that feeling ever since, whether it's comparing how AI and humans write song lyrics or how far apart two water polo teams are on a map.

Outside of that, I'm into statistics, artificial intelligence, and the ways data can explain human behavior. My work includes published and ongoing research in AI-generated language, sports analytics, and marketing — including a first-author article in the Journal of Emerging Investigators and a second sports-analytics manuscript currently under review at European Sport Management Quarterly.

I also founded Ashberry Entertainment, where I develop and publish educational and casual mobile applications for iOS and Android. Through research, software development, and InnoYouth, I enjoy turning ideas into projects that can be tested, shared, and used in the real world.

Probably a side effect of growing up between New Zealand and coastal California, but I never really stopped loving the water. I play center — also called hole set — for Troy High School's water polo team: back to the goal at the two-meter line, fighting for position the entire game, and usually the player the offense is built around. It's one of the most physical spots in the pool, and I love it. When I'm not in the water for that, I'm usually in it anyway — sailing or just swimming.

02 Research & Publications

Six research projects spanning generative AI, environmental modeling, sports analytics, and applied machine learning — three with a peer-reviewed outcome.

Published — Journal of Emerging Investigators, Oct 2026

Geographic Proximity to Strong Competitors and Team Performance in High School Water Polo

Analyzed season-record performance and geographic location data from 755 U.S. high school boys' water polo teams using Moran's I and k-nearest-neighbor spatial methods. Contrary to the original hypothesis, results showed weak but statistically significant spatial dispersion rather than positive geographic clustering, both nationally and within California. First-author article, conducted with Professor Young Bae (Penn State University).

Are AI-Generated Song Lyrics Less Diverse Than Human Lyrics?

A matched comparison of 213 human-written songs and 628 lyrics generated by Claude Sonnet 4.5 across three sampling temperatures. Measured semantic diversity using sentence embeddings and lexical diversity using MTLD, adjusting for genre and lyric length. AI-generated lyrics showed substantially lower semantic dispersion but higher lexical diversity than human lyrics; raising temperature increased lexical diversity without increasing semantic dispersion. Advanced to the second round of the International Journal of Arts and Sciences Competition (IJAC) 2026.

Public Rankings, Rank Responsiveness, and Persistent Published-versus-Record Differences in U.S. High School Water Polo

Built and analyzed a longitudinal dataset of 3,500+ team-seasons across 600+ programs using MaxPreps data and Python. Applied regression and fixed-effects models to study how publicly reported rankings respond to, and lag behind, real changes in team performance. Co-authored with Professor Young H. Bae, Penn State University.

OCSEF 2025 — Outstanding Achievement

A Dynamical Model for PM2.5 Accumulation and Removal

Developed a first-order dynamical model of PM2.5 concentration based on competing accumulation and meteorological removal processes. Derived the model's equilibrium, established global asymptotic stability, and analyzed recovery time and resilience, validating results through numerical simulation and sensitivity analysis. Presented at the 71st Annual Orange County Science & Engineering Fair.

Modeling Meteorological Controls on PM2.5 Recovery in Orange County, California

Extended earlier PM2.5 modeling work to examine how wind, precipitation, and background decay influence pollution persistence and recovery. Estimated model parameters from 4,105 daily observations (EPA/NOAA, 2014–2024); the fitted model achieved an RMSE of 4.40 µg/m³ and MAE of 2.85 µg/m³, with stability analysis confirming recovery toward a unique equilibrium after pollution shocks.

WAICY 2025

AI-Based Wildfire Vulnerability Index for California

Built a community-level wildfire vulnerability index integrating CAL FIRE, U.S. Census, CDC, and USGS data across fire hazard, social vulnerability, and emergency access. Trained a lightweight nonlinear MLP neural network on ten geospatial and socioeconomic features, achieving an MSE of 0.0004 and MAE of 0.0125, to support early risk identification and equitable resource allocation.

InnoYouth

45,000+

new Braille books coordinated for distribution to nonprofits, schools, and libraries serving children with visual impairments

I founded InnoYouth in September 2024 to expand access to educational resources for children and underserved communities. Beyond leading the Braille-book initiative, I built partnerships with organizations including Orange County United Way, led outreach and logistics, and built and run the organization's website and public presence.

05 Apps & Projects

Founding Fathers Quiz

An educational mobile quiz app about the Founding Fathers and early American history, built end-to-end — content, UI, testing, and store release — under Ashberry Entertainment. Started life as Voices of the Founders, a Congressional App Challenge submission, before launching publicly on iOS and Android.
