IMPS Presentation

Presentation at the 2026 International Meeting of the Psychometric Society

I recently presented our research, Pairwise Target Rotation for Factor Models, in an oral session at the 2026 International Meeting of the Psychometric Society (IMPS) held at Yonsei University in Seoul, South Korea back in July 2026. This work focuses on developing an intuitive yet flexible method for incorporating a priori information, such as item semantics, into factor rotations. The approach can be used to produce interpretable factor solutions and effectively characterize latent variables.

AERA Presentation

Poster at the 2026 American Educational Research Association Annual Meeting

Our work, Design and Implementation of Reduced Longitudinal Experiments, was selected from over 13,000 submissions for poster presentation at the 2026 American Educational Research Association (AERA) Annual Meeting. It focuses on characterizing hierarchical linear models to produce practical recommendations for designing and implementing longitudinal experiments. My co-author, Le Dolino, presented our paper at the conference back in April 2026 in Los Angeles, California.

About Me

Profile & History

I am an early-career Data Scientist and Researcher passionate about statistics and machine learning. My work centers on developing novel quantitative methods, as well as intelligent systems, and creatively applying such, ultimately combining rigorous modeling with clever approaches to uncover complex patterns in data. Currently, my research and professional practice focus on latent variable models, mixed-effects models, and causal machine learning.

Moreover, I am currently pursuing an M.S. in Computer Science degree at the University of the Philippines Diliman (UPD), where I am affiliated with the Computer Vision and Machine Intelligence Group of the Department of Computer Science. I previously earned my B.S. in Statistics degree from UPD, graduating summa cum laude back in 2023.

Outside of academics and work, I enjoy playing video games and playing the guitar. 🙂

Pairwise Target Rotation for Factor Models

We developed a new factor rotation method (an unsupervised learning technique) and its Python implementation, that can incorporate arbitrary prior information (e.g., semantics) for exploration and model building.

Presented at the 2026 International Meeting of the Psychometric Society (IMPS) in an oral session.

Won 1st Place Best Graduate Student Paper Award at 25th Student-Faculty Conference on Statistical Sciences.

Impact: New method (unsupervised learning) that can be used to effectively uncover latent structures.

Design and Implementation of Reduced Longitudinal Experiments

We characterized hierarchical linear models through the design and analysis of a Monte Carlo experiment (including the simulation of nested data, attrition, and more), implemented in R, to produce recommendations for longitudinal experiments.

Presented at the 2026 American Educational Research Association (AERA) Annual Meeting in a poster session.

Impact: Useful practical recommendations for designing and implementing robust longitudinal experiments in resource-limited contexts.

FactorFlow: A Visual Analytics Workspace with Large Language Model-Assisted Interpretation for Factor Analysis

I developed an LLM-enhanced visual workbench for exploratory factor analysis with interactive model building and automated interpretation.

Impact: End-to-end workspace for exploratory factor analysis with comprehensive visualizations and automated interpretation.

Match App

I implemented Gower’s Distance and Binary Integer Linear Programming using R and created a web app for a student council initiative that involved optimally grouping students for theses.

Impact: Optimal and automated groupings, ensuring compatible work styles and research interests among students.

Predicting IDH Mutation in Gliomas Using Attention-based Multiple Instance Learning

I applied computer vision methods and attention-based multiple instance learning to predict the isocitrate dehydrogenase (IDH) mutation status of a glioma based on magnetic resonance imaging (MRI) scans, exploring a non-invasive way of classifying gliomas while including an ablation study that combines scans with radiomics.

Impact: Achieved an ROC-AUC of about 0.90 and a macro PR-AUC of about 0.89

TREE$

I made a game for one of my courses during my first semester in college. The game was made using Unity, with C# as the programming language. The simple design assets were made using Microsoft PowerPoint while the background music was created using Chrome Music Lab - Song Maker.
