Creation of reconfigurable and multi-functional materials can be achieved by incorporating architecture into material design. In our research, we design and fabricate three-dimensional (3D) nano-architected materials that can exhibit superior and often tunable mechanical, thermal, photonic, electrochemical, and biochemical properties at extremely low mass densities, which renders them useful and enabling in technological applications. Dominant properties of such meta-materials are driven by their multi-scale hierarchy: from characteristic material microstructure (atoms) to individual constituents (nanometers) to structural components (microns) to overall architectures (millimeters and above).

Our research is focused on the fabrication, synthesis, and characterization of hierarchical materials using additive manufacturing (AM) techniques, as well as on investigating their mechanical, electrochemical, and chemo-mechanical properties as a function of architecture, constituent materials, and microstructural detail. AM represents a set of processes that fabricate complex 3D structures using a layer-by-layer approach, with some advanced methods attaining nanometer resolution and the creation of unique, multifunctional materials and shapes derived from a photoinitiation-based polymerization of custom-synthesized resins and thermal post-processing. A type of additive manufacturing, vat polymerization via hydrogel infusion (HIAM), has allowed for using hydrogels as precursors to produce 3D nano- and micro-architected metals and metal oxides, and exploiting their nano-induced material and structural properties. We describe additive manufacturing via vat polymerization and function-containing chemical synthesis to create 3D nano- and micro-architected metals, ceramics, multifunctional metal oxides, and metal-containing polymer complexes with dynamic bonds, as well as demonstrate their potential in energy storage, microrobotics, and nano- and micro-electronics. I will describe how the choice of architecture, chemical composition, and microstructure can elicit new microstructural orders and induce stimulusresponsive, reconfigurable, and multifunctional response.

Greer’s research focuses on the design, synthesis, fabrication, and characterization of nanoarchitected materials using additive manufacturing (AM) techniques, as well as on investigating their mechanical, electrochemical, and chemo-mechanical properties as a function of architecture, constituent materials, and microstructural detail. We strive to uncover the synergy between the internal atomic- and molecular-level microstructure and the multi-scale external dimensionality, where competing material- (nano) and structure- (architecture) induced size effects drive overall response and govern these properties. Specific topics include applications of 3D nano- and microarchitected materials in devices, energy absorption, ultralightweight energy storage systems, mechanochemistry, reconfigurable and multi-functional materials, and additive manufacturing.

Reconstruction of Left Ventricular Pressure Using Cardiovascular Mechanics

Coskun Bilgi

Postdoctoral Researcher
Department of Aerospace & Mechanical Engineering
University of Southern California
Los Angeles, CA

Left ventricular (LV) pressure is a fundamental quantity that provides a direct window into the mechanics and energetic performance of the heart. However, LV pressure is typically measured through invasive cardiac catheterization, limiting its accessibility for routine and longitudinal assessment. This talk will present our efforts to reconstruct the LV pressure waveform noninvasively using a physics-based approach. The cardiac cycle consists of physiologically distinct phases. Rather than describing the entire pressure waveform using a single empirical function, our framework identifies key physiological time instances throughout the cardiac cycle and reconstructs the pressure between them using principles of fluid and solid mechanics. By coupling these phase-specific descriptions through physiological conditions, a continuous LV pressure waveform can be reconstructed and clinically important hemodynamic indices can be estimated without direct ventricular catheterization. We will discuss the development of this framework and its evaluation across both human and preclinical studies. In retrospective human data, reconstructed LV pressure and pressure-derived indices differentiated healthy individuals from patients with heart failure. In preclinical experiments with simultaneous invasive pressure measurements, the method accurately reproduced important hemodynamic metrics across varying cardiac conditions. Together, these studies demonstrate how combining cardiovascular physiology with fundamental mechanics represents a promising step toward the noninvasive diagnosis and monitoring of cardiovascular conditions.

Coskun Bilgi is a postdoctoral researcher in the Department of Aerospace and Mechanical Engineering at the University of Southern California.

From Surrogates to Solvers: Physics-Embedded Vision Transformers and Foundation Models in Mechanics

Benjamin A. Jasperson

Postdoctoral Scholar
Department of Aerospace & Mechanical Engineering
University of Southern California
Los Angeles, CA

Accurately predicting the behavior of advanced mechanical systems and materials requires capturing complex multiscale phenomena and rare events. While classical numerical methods offer high fidelity, their immense computational costs, especially when bridging disparate scales, often bottleneck the research and design cycle. Artificial intelligence provides a fast, compelling alternative, yet transitioning these tools from black-box data surrogates to rigorous, physics-aware solvers remains a critical challenge.

This talk explores the intersection of solid mechanics and interpretable AI, focusing on strategies to combine the guarantees of traditional solvers with the speed of deep learning. We will examine Vision Transformers (ViTs) as foundational architectures, specifically evaluating their accuracy, numerical stability, and overall performance when applied to continuum mechanics compared to classical methods.

Moving beyond standard surrogate modeling, we will tackle the unique computational challenge of predicting rare events, centered around understanding how unit mechanisms influence crack self-healing in metals. We will discuss how foundation models can map heterogeneous, multiscale materials data into a shared latent space, yielding frameworks that are highly descriptive and predictive of these highly localized phenomena. Finally, we will conclude with a broader vision for the future of AI-embedded computational mechanics.

Homogenizing Origami and Kirigami Metamaterials

Paul Plucinsky

Assistant Professor
Aerospace & Mechanical Engineering Department
University of Southern California
Los Angeles

Shape-morphing finds widespread utility, from the deployment of small stents and large solar sails to actuation and propulsion in soft robots. Kirigami and origami metamaterials, formed by repeating patterns of slits, creases and panels, are a versatile platform for shape-morphing, inspiring the design of many morphing structures and devices. However, it remains a challenge to predict the response of these and other metamaterial systems to a broad range of loads and stimuli, especially under large deformations.

This talk describes general theoretical principles for homogenizing origami and kirigami metamaterials. Our broad goal is to derive, from first principles, an effective mechanical theory for their bulk deformations, valid in the limit of a large number of building blocks. The first part discusses kirigami; the second discusses origami. We present the foundational ingredients of the theory and give numerical demonstrations of its predictive power.

Engineering Human Health: Biomechanics, Medical Imaging, and Patient-Specific Modeling

Kaveh Laksari

Assistant Professor
Mechanical Engineering Department
University of California, Riverside
Riverside, CA

The human body is a complex mechanical system in which structure, material properties, and physiological function are intimately connected. Yet many of the mechanical processes underlying injury and disease cannot be measured directly in humans. Our laboratory develops engineering approaches that combine biomechanics, medical imaging, computational modeling, biomedical devices, and data-driven methods to uncover these hidden relationships and translate them into tools for understanding and improving human health. In this talk, I will highlight three areas of our research that span scales from tissue mechanics to patient-specific physiology. First, I will discuss our work in traumatic brain injury, where wearable sensors, neuroimaging, and computational models are used to connect head impact biomechanics with changes in brain structure and function. Second, I will describe approaches for characterizing the mechanical behavior of biological materials, including inverse methods that combine experiments and computational mechanics to determine material properties that are difficult to measure directly. Finally, I will present our work in cerebrovascular biomechanics and stroke, where large-scale vascular imaging, automated vessel reconstruction, computational hemodynamics, and machine learning are being integrated to characterize patient-specific cerebrovascular anatomy and function and ultimately improve stroke assessment and outcome prediction.

Together, these studies illustrate a broader research vision: using engineering to infer physiological information that cannot be directly observed, and integrating experiments, imaging, mechanics, and computation toward predictive, patient-specific models of human health.

Advanced Manufacturing of Stretchable Electronics for Soft Biological and Robotic Systems

Hangbo Zhao

Assistant Professor
Department of Aerospace and Mechanical Engineering
University of Southern California
Los Angeles, CA

Electronics that stretch and conform open new possibilities for interfacing with soft biological and robotic systems, but they cannot be built with the planar, rigid-substrate processes that modern microfabrication was designed around. My group develops manufacturing methods that close this gap, and I will organize the talk around two routes we have pursued. The first reshapes conventional high-performance materials into stretchable form, using micromachining, transfer printing, and mechanically guided assembly to build microneedle electrode arrays for electromyography and origami-inspired strain sensors for soft robot shape perception. The second patterns intrinsically stretchable materials at microscale resolution, where colloidal self-assembly of liquid metal particles and microtransfer printing produce high-resolution electronics that we used for in vivo cardiac mapping.

The Fluid Mechanics of Stroke: unraveling the role of flow and transport in complex cerebrovascular networks

Debanjan Mukherjee

Assistant Professor of Mechanical Engineering
Paul M. Rady Department of Mechanical Engineering
University of Colorado
Boulder, Colorado

Despite many recent medical advances, stroke continues to be a leading global cause of death and disability. The latest American Heart Association statistics reveal that, on average, someone in the United States dies of a stroke every 3 minutes and 14 seconds. As a disease that stems from flow disruption in the brain due to blockage or rupture of an artery in the brain, fluid mechanics plays an intimate role in stroke etiology and treatment. Yet, owing to the inherent complexity of blood flow through complex cerebrovascular network, and associated cerebrovascular physiology, our understanding of the role of fluid mechanics in stroke remains incomplete at best. Here, I will outline a combination of computer simulations, benchtop experiments, and medical image analytics to address this knowledge gap. I will illustrate how we have leveraged this hybrid approach to study mechanisms of ischemic stroke due to embolisms, understand the role of collateral circulation in the brain, and illustrate network level non-linear flow effects that mediate transport of drug such as tissue Plasminogen Activator (tPA) for stroke treatment. Through these examples, we will present a framework for data-integrated digital twins for stroke, and discuss some of the associated challenges and opportunities in developing and translating such digital twins for advancing stroke care.

He is also a program faculty for the Biomedical Engineering program, and a faculty council member at the BioFrontiers Institute at CU Boulder.

What Cameras Can and Cannot See in a Flame: Physics-Constrained Reconstruction of Combustion Fields from High-Speed Video

Benjamin Cohen

Ph.D. Student
Department of Aerospace & Mechanical Engineering
USC
Los Angeles, CA

Visual measurements offer only a partial projection of the physical world. What we can recover depends on both how well we quantify the measurement process and what we know about the system's physics. Physical laws can constrain fields that measurements alone cannot determine. This talk applies that idea to premixed combustion imaging. The study focuses on a lean hydrogen flame propagating through a 6 mm gap between parallel plates, a Hele-Shaw cell used in Prof. Paul Ronney's Combustion Physics Lab at USC to study confined flame propagation. The narrow gap shortens the optical path, simplifying the link between the flame's local thermochemical state and the measured light. Three synchronized high-speed cameras record the flame. High-speed cameras capture only light integrated along a line of sight. Since temperature, species concentrations, velocity, and pressure are not measured, models of light emission, optical projection, and reacting-flow dynamics must be used to infer them. As a result, this is an ill-posed inverse problem. The seminar examines what is required to set up and solve this inverse problem, and what uncertainty remains in the resulting reconstruction of the physical flame.

Benjamin Cohen is a Ph.D. student in Mechanical Engineering at the University of Southern California, where he works in Prof. Paul Ronney's Combustion Physics Lab. His research uses high-speed imaging of quasi-two-dimensional flames in Hele-Shaw cells, together with computer vision and physics-informed machine learning, to reconstruct combustion fields from video. Before his doctoral work, he studied graph neural networks and convex optimization as a USC SURF fellow. He enjoys pure mathematics and is a two-time Putnam Competition finalist.

Designing Heterogeneity in Structural Metals: Processing and Deformation Mechanisms

GangHee Gu

Postdoctoral Scholar
Department of Aerospace & Mechanical Engineering
USC
Los Angeles, CA

Microstructural heterogeneity offers a route to improving the strength–ductility balance in structural metals. This seminar connects processing, deformation mechanisms, and optimization through experiments and modeling. Cold rolling, local laser treatment, and high-pressure torsion with annealing establish gradient and layered architectures. Plasma nitriding extends this concept to the nanoscale, combining surface strengthening with recovery-assisted ductility. Finally, dislocation-based modeling and finite element analyses assess additional hetero-deformation-induced (HDI) contributions and examine how domain size and volume fraction influence deformation localization. The results highlight the benefits of fine soft domains within a hard matrix in the investigated microstructures, illustrating how understanding deformation mechanisms can guide the optimization of heterostructured metals.

GangHee Gu is a Postdoctoral Scholar in the Department of Aerospace and Mechanical Engineering at the University of Southern California. He received his Ph.D. in Materials Science and Engineering from Pohang University of Science and Technology (POSTECH), South Korea, in 2025.

The Multivariate Cauchy Estimator

Jason L. Speyer

Distinguished Professor, Ronald and Valerie Sugar Endowed Professor of Engineering
Mechanical and Aerospace Engineering Department
UCLA
Los Angeles, CA

The multivariate Cauchy estimator (MCE) provides an exact Bayesian filtering framework for discrete-time linear dynamic systems subject to additive Cauchy process and measurement noise, a direct analog to the Gaussian-based Kalman filter. For an n-dimensional system (n>1), applying Bayes’ rule directly in the state domain fails to yield a recursive, closed-form conditional probability density function (cpdf). However, propagating the cpdf’s characteristic function (the Fourier transform of the cpdf) produces the same analytic function through measurement updates and dynamic propagations, establishing the MCE as the only estimator derived in the characteristic function spectral domain and, alongside the Kalman filter, the only known filter with exact recursive analytic properties. Because heavy-tailed Cauchy distributions process measurement updates through nonlinear operations, the MCE can model asymmetric and multimodal state distributions that are impossible under the linear-Gaussian framework. The development of computationally efficient numerical methodologies now enables real-time application of this theory to complex engineering systems. When compared against the Extended Kalman Filter (EKF), numerical evaluations of the Extended MCE (EMCE) demonstrate superior performance and robustness in handling system parameter uncertainty within Gaussian simulations, suppressing severe impulsive radar noise in missile tracking, and estimating the position, velocity, and atmospheric density of Very Low Earth Orbit (VLEO) satellites operating in impulsive atmospheric environments.

Dynamics of Droplet Impact from Engineering to Environmental Systems

Abhishek Saha

Associate Professor
Department of Mechanical and Aerospace Engineering
University of California San Diego
La Jolla, CA

Droplet impact is ubiquitous in natural and engineering processes. From raindrops falling onto the ocean to applications such as additive manufacturing, inkjet printing, and spray coating, droplet impact plays a critical role in mass, energy, and species transport. In this talk, we will discuss two classes of droplet impact problems.

In the first part, we will explore substrate oscillation as a strategy for controlling droplet spreading on solid surfaces. We will examine how spreading depends on oscillation frequency, amplitude, and phase, and develop scaling analyses to guide design optimization. We will then highlight the striking changes in impact dynamics as substrate oscillation shifts from low to high frequencies and discuss the mechanisms governing the high-frequency response.

In the second part, we will focus on raindrop impact on ocean waves. The resulting atomization and mixing influence air–sea exchange, with implications for marine life, climate, and coastal environments. Although field campaigns have provided limited measurements of the collective and stochastic effects, our understanding of individual droplet–wave interactions remains limited. We will present laboratory experiments using a new benchtop wave tank to examine these interactions in detail. Specifically, we will explore how waves influence cavity formation and jetting following droplet impact, and how wave conditions modulate jet breakup and secondary droplet formation.
