Kyle Luh, Department of Mathematics, University of Colorado Boulder Extreme Eigenvalues of a Random Laplacian Matrix The extreme eigenvalues of a random matrix have been important objects of study since the inception of random matrix theory and also have a variety of applications. The Laplacian matrix is the workhorse of...

Alessandro Peri, Department of Economics, University of Colorado Boulder Programming FPGAs for Economics: An Introduction to Electrical Engineering Economics We show how to use field-programmable gate arrays (FPGAs) and their associated high-level synthesis (HLS) compilers to solve heterogeneous agent models with incomplete markets and aggregate uncertainty (Krusell and Smith, 1998)...

Alexander Young, Anderson School of Management, University of California - Los Angeles (UCLA) Inferring genetic causation using randomization of genetic material within families and modeling intergenerational inequalities Multiple phenomena contribute to genotype-phenotype associations: causal effects of alleles carried by the individual on the individual (direct genetic effects); effects of alleles...

Daniel Rothman; Department of Earth, Atmospheric, and Planetary Sciences; Massachusetts Institute of Technology Excitations of Earth's Carbon Cycle Mysterious, transient changes in the ocean's store of carbon occur intermittently throughout Earth's history. Each of these events coincides with climate change; moreover, mass extinctions are always accompanied by such events. What...

Stephanie Chaillat, Laboratoire POems, École Nationale Supérieure de Techniques Avancées Paris Fast Boundary Element Methods to simulate underwater explosions and their interactions with submarines Assessing the impact of underwater explosions on submerged structures (submarines) is an important naval engineering problem. An underwater explosion mainly induces two distinct phenomena: a "shock...

Robert MacCurdy, Department of Mechanical Engineering, University of Colorado Boulder Automated Design and Fabrication of Multimaterial Soft Robots Current electromechanical design practice is predicated on the exercise of expert-level judgement through an interactive and iterative design and fabrication process that requires skilled humans at every step. This approach doesn't scale...

Heather Wilber, Oden Institute, University of Texas at Austin Rational functions in computational mathematics From dynamical systems and signal processing theory to core algorithms in numerical linear algebra, rational approximation theory has always shaped the way we think about computational mathematics. Even so, outside of a few very active areas,...

Mark Ablowitz, Department of Applied Mathematics, University of Colorado Boulder Looking Back: Reflections on Research and Teaching Mark J. Ablowitz is the recipient of the 2022 Hazel Barnes Prize. This is the most prestigious single faculty award funded by the University of Colorado Boulder. It was established in 1991 to...

Peter Hamlington, Department of Mechanical Engineering, University of Colorado Boulder The Structure and Dynamics of Puffing Plumes The near-field characteristics of highly buoyant plumes, commonly referred to as lazy plumes, remain relatively poorly understood across a range of flow conditions, particularly compared to our understanding of far-field characteristics. Buoyant plumes...

Dorit Hammerling, Department of Applied Mathematics and Statistics, Colorado School of Mines Lossy Data Compression and the Community Earth System Model Climate models such as the Community Earth System Model (CESM) typically produce enormous amounts of output data, and storage capacities have not increased as rapidly as processor speeds over...
