<description>Our AIAA SCITECH '26 conference paper, focusing on <a href='https://doi.org/10.2514/6.2026-1812' target='_blank'>symbolic computational abstraction of chemistry libraries</a> is now available online. Work with Ph.D. student Dimitrios Adam and UTSI faculty Esteban Cisneros-Garibay. We will be presenting it during the <a href='https://arc.aiaa.org/doi/book/10.2514/MSCITECH26' target='_blank'>SCITECH forum</a> next week, Jan 12-16, 2026.</description>

<description>A new group preprint by graduate student Haocheng Yu and postdoc Tianyi Chu, <i>Energy dissipation mechanisms in an acoustically-driven slit</i>, is <a href='https://doi.org/10.48550/arXiv.2512.19507' target='_blank' rel='noopener noreferrer'>available on arXiv</a>. Using DNS and spectral POD, we quantify how incident acoustic energy is converted into vortical motion and viscous dissipation, identifying the coherent structures and mechanisms that govern absorption.</description>
