<b>Abstract: </b></div>
<div style="text-align: left; text-indent: 0px; margin: 0px 0px 14px; font-family: Tahoma, Geneva, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);" class="elementToProof">
In this talk, I will present my research on the development of scalable, hardware-aware numerical algorithms for solving complex partial differential equations (PDEs) on leadership-class supercomputers. By co-designing algorithms with architectural constraints
in mind, my work enables high-fidelity simulations that were previously computationally infeasible. I will highlight key algorithmic advances and demonstrate their impact through three representative application areas:</div>
<ul style="text-align: left; margin-top: 0px; margin-bottom: 14px;">
<li style="font-family: Tahoma, Geneva, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
(A) Micro-scale physics, where I develop scalable solvers for the Boltzmann transport equation to model electron transport in low temperature plasmas;</li><li style="font-family: Tahoma, Geneva, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
(B) Relativistic astrophysics, where communication-avoiding and extreme-scale AMR enables large-scale simulations of the Einstein field equations for binary black-hole mergers and resulting gravitational waves; and</li><li style="font-family: Tahoma, Geneva, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
(C) Real-time Bayesian inversion, where the underlying problem structure is exploited to develop fast Hessian matrix–vector products that enable extreme-scale, real-time Bayesian inversion for a tsunami early warning system.</li></ul>

Together, these examples illustrate a unifying theme: carefully designed scalable algorithms are a prerequisite for extracting scientific insight from next-generation computing platforms. I will conclude by outlining my vision for future research in extreme-scale
algorithms and their role in advancing science and engineering in the exascale era.</div>
