Congratulations to my friend and colleague Professor Stuart Laurence at the University of Maryland on his team’s publication Experimental study of fluid-thermal-structural interactions in a Mach-10 compression corner using super-ellipse-based photogrammetry in the Experiments in Fluids journal. Congratulations are also due to the entire NASA team, lead by Greg Buck, for their expertise in s…

Congratulations to former PhD student and now Dr. Sandeep Murthy on his publication of Resolvent Analysis for Shock-Laden Flows in the Journal of Fluid Mechanics. Through detailed and inspired analysis, Sandeep shows how to properly interpret the input-output-gain structure of the linearized Navier-Stokes operator in the presence of a shock wave using inviscid, viscous, and […]

The just-accepted paper “Petrov-Galerkin model reduction for collisional-radiative argon plasma,” written by (now Dr.) Ivan Zanardi and Dr. Alby Padovan was chosen by Physics of Plasmas for its Editor’s Pick! Congratulations Ivan and Alby!

In our study of the origins of patterned formations on sublimating and ablating bodies, our local linear stability analysis has uncovered (what appears to be) the first known physical mechanism of their formation via differential ablation in laminar flows. More details on arXiv and a forthcoming article in the Journal of Fluid Mechanics. Congratulations to […]

Professor Bodony will give an invited lecture on Gas-Material Interactions for the NATO STO-AVT-358 LS on Advanced Computational Fluid Dynamic Methods for Hypersonic Flows, 1-4 December 2025. The Lecture Series has been rescheduled for late winter / early spring of 2026 due to the US government shutdown.

Led by Dr. Alberto (Alby) Padovan, a Python-based package for analyzing large-scale linear systems, such as derived from fluid dynamics simulations, has been released on github: https://github.com/albertopadovan/resolvent4py. SoftwareX and arXiv have more documentation.

I am so pleased to announce that (now) Dr. Sandeep Murthy successfully defended his PhD thesis “Reducing Noise from Supersonic Jets using Linear Feedback Control informed by Resolvent Analysis” in January, 2025. Congratulations, Sandeep!

Bodony has been honored and will give the keynote talk at the 16th ERCOFTAC SIG 33 Workshop on Progress in Flow Instability, Transition, and Control, from June 30–July 2, 2025. More details to follow.

Congratulations to Dr. Fabian Dettenrieder for successfully defending his PhD thesis titled Fluid Structure Interaction in Compressible Viscous Flows in November, 2024.

Congratulations to Dr. Alby Padovan and Mr. Blaine Vollmer for their paper accepted to SIADS: Padovan, A., Vollmer, B., and Bodony, D. J. “Data-driven model reduction via non-intrusive optimization of projection operators and reduced-order dynamics,” accepted for publication in the SIAM Journal on Applied Dynamical Systems. Here’s the arXiv version.

In collaboration with the Center for Hypersonics and Entry System Studies, several post-doctoral opportunities are available. The full announcement is available here.

Building on our group’s success in modeling ablative systems and studying linear stability, we combined those capabilities to study the physical origins of differential ablation, found on many ablative systems but as-yet not fully explained. We are excited to work with our DoE partners at Sandia National Laboratory.
