2026


October 2026

Professional Service — IEEE ICASSP 2027

I accepted an invitation to serve as a reviewer for the 2027 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP 2027) .

Invited Talk — Oregon State University Applied Mathematics and Computation Seminar

I gave an invited talk, “Dynamical System Autoencoders and Representation Learning,” in the Applied Mathematics and Computation Seminar at Oregon State University on October 2, 2026.

The talk examined hidden-state dynamics in Dynamical System Autoencoders and how repeated encoding affects learned representations, combining mathematical analysis with computational experiments on 3D LiDAR point clouds.

Undergraduate Research Mentoring — CREST REU

I mentored undergraduate researcher Evelyn Pulla through the CREST REU program. Her summer research culminated in a poster presentation in August 2026.


July 2026

New Preprint — Dynamical System Autoencoders for LiDAR Classification

Our preprint, “Depth-Dependent Hidden-State Collapse in Dynamical System Autoencoders for LiDAR Point-Cloud Classification,” with Hy P. G. Lam, is available on arXiv.

The work studies how repeated transformations in dynamical autoencoder architectures affect hidden representations and downstream classification.
