Horacio Castillo

Horacio Castillo is an Associate Professor in the Department of Physics and Astronomy at Ohio University, affiliated with the Nanoscale Quantum Phenomena Institute (NQPI). His research focuses on condensed matter theory, particularly glassy dynamics, dynamical heterogeneities, and non-equilibrium systems. He explores topics such as fluctuating relaxation times, aging dynamics, and the interplay between structure and dynamics in supercooled liquids and amorphous solids.

Key research areas include the study of glass transition phenomena using molecular simulations and theoretical models. His work addresses questions about spatial and temporal correlations in glass-forming systems, dynamic susceptibility, and the application of spin-glass concepts to biological reprogramming processes. Castillo’s contributions span experimental collaborations and computational studies, with a focus on advancing understanding of complex materials and their underlying physics.

Publications highlight advancements in characterizing rotational/translational dynamics in supercooled liquids, modeling dynamic heterogeneity, and analyzing aging regimes in silica glasses. His research bridges traditional condensed matter physics with interdisciplinary topics such as biophysics, leveraging tools from statistical mechanics and nonlinear dynamics.

Castillo has contributed to the Ohio University community through involvement in academic events like the NQPI-CMSS Joint Poster Session (2015) and mentoring student research projects, as evidenced by his presence in student research expos. His grants and collaborations reflect a commitment to advancing fundamental knowledge in nanoscale and quantum phenomena.
