Advances in early detection of disease and increases in lifespan necessitate new strategies to repair or replace damaged organs and tissues. My research is directed toward incorporating cues from the native environment and natural extracellular matrix (ECM) into the design of cell culture platforms and musculoskeletal tissue engineered constructs. By applying fundamental principles in cell and molecular biology, biomaterials, and biotransport phenomena, we are developing materials-based strategies to direct the behavior of transplanted or host cells within bone defects and interrogate the behavior of various cell populations in more physiologically relevant conditions. In this talk, I will present examples of our recent work in designing biomaterials from cells and natural and synthetic polymers to instruct cell fate and enhance tissue formation and function with applications in bone regeneration and repair.

Abstract:
Solar electric propulsion (EP) is a key technology for human and robotic space missions, and is part of NASA’s vision for expanding human presence beyond low earth orbit. The high specific impulse of EP enables reductions in propellant mass, but at the price of long burn times. Deep space missions re-quire operating times of many 104 hours. Demonstrating that the thruster meets this requirement is a challenge. Multiple life tests of the full mission duration are not practical. The life capability must be demonstrated by combining physics-based modeling and short duration testing.
JPL developed the CEX2D and CEX3D codes to model erosion of ion accelerator systems in ion engines, a dominant failure mechanism. The codes model a primary ion beamlet and charge exchange (CEX) ions from the beamlet. Impingement of main, beamlet, and CEX ions on the grids then determine erosion rates. The models predict time-to-failure, but key questions include: What is the uncertainty in those estimates? How much margin is needed to account for the uncertainties? Estimating uncertainty in experiments is routine, but the modeling community is still developing techniques for estimating errors. In this talk we discuss the physical processes of ion engine grid erosion, how they are modeled, and methods for quantifying model uncertainty and required life margins.

he future Aguado Research Group will develop “precision biomaterials” that enable the evaluation of a patient’s unique biology to diagnose and treat a variety of health disorders as a function of sex, age, and/or ancestry. Precision medicine is a movement in clinical practice that seeks to develop therapies tailored for specific patients or subsets of patients. As mounting evidence suggests that the “one size fits all” approach to medicine is ineffective, my future lab seeks to exploit biomaterials as in vitro culture tools or implantable devices in vivo to understand how patient-specific variables may impact disease onset, progression, and treatment. In my talk, I will describe my past, present, and future work in precision biomaterials. During my graduate training with Prof. Lonnie Shea at Northwestern University, I developed implantable biomaterial scaffolds for the recruitment and early detection of metastatic cancer cells, which may serve as a platform to capture disseminating tumor cells for downstream precision medicine applications. My current postdoctoral research with Prof. Kristi Anseth at the University of Colorado Boulder is focused on engineering personalized in vitro disease models of aortic valve stenosis using serum from individual aortic valve stenosis patients to culture valve and cardiac fibroblasts and hydrogels as extracellular matrix mimics. I will also share my outlook for future work in exploring sex differences in cardiovascular disorders using precision biomaterials. In sum, precision biomaterials may serve as tools to improve our understanding of how patient-specific variables impact disease mechanisms and guide more effective diagnostics and treatments for individual patients or subsets of patients.

Talk Overview:

Cancer immunotherapy has achieved significant clinical success in the past few years, but there remains tremendous room for the development of new-generation therapies with more robust and persistent antitumor immune responses. My research interests are largely directed towards understanding how cancer cells and immune cells can be manipulated or engineered using chemistry, material, and chemical biology approaches, in order to develop effective therapies for cancers, injured tissues, and other diseases. In this talk, I will start with my phd journey in exploring cancer-selective metabolic labeling and targeting, and then share how metabolic cell labeling can be utilized for tracking and targeted modulation of immune cells in vivo. Lastly, I will talk about a biomaterial-based antigen-free cancer vaccine for the treatment of poorly-immunogenic solid tumors.

Bio:

I am currently a Wyss Technology Development Fellow at Harvard University, aiming to integrate my research background in chemistry, materials science, and chemical biology with cancer immunotherapy and immunoengineering here. More specifically, I am exploring approaches to modulate or engineer cancer and immune cells in vivo, in order to improve and innovate current immunotherapies for cancers and other immune-related diseases. Before moving to Harvard, I earned my Ph.D. degree in Materials Science and Engineering at the University of Illinois at Urbana-Champaign (08/2012-06/2016), and my Bachelor’s degree in Polymer Science and Engineering at the University of Science and Technology of China (08/2008-06/2012).

Signaling is governed not only by the expression levels of molecules, but by their localization via mechanisms as diverse as compartmentalization in organelles, phase separation, and directed transport by motor proteins. Cell morphology likely also modulates the localization of signaling molecules, and recent advances in high-resolution light-sheet microscopy, such as lattice light-sheet microscopy, now allow imaging at the spatiotemporal resolution needed to capture the many undulations and quick dynamics of the 3D cell surface. However, these microscopes generate large datasets with detailed 3D movies that are impossible to interpret without a dedicated computational pipeline. In this seminar, I will introduce u-shape3D, a computer graphics and machine-learning pipeline to probe molecular mechanisms underlying 3D cell morphogenesis. U-shape3D includes a generic morphological motif detector that automatically finds lamellipodia, filopodia, blebs and other motifs in order to test the intriguing possibility that morphogenesis itself affects intracellular signaling.

In today’s research we often talk about knowledge-extraction from Big Data, and integration across different scales: molecules, cells, tissues/organs, organisms and their communities. The pursuit of multi-scale synthesis has a long history. For the microscopic world we have largely succeeded in connecting the chemical properties of molecules with the facts of atoms and their constituents and interactions. In epidemiology, many are currently applying linear mixed models to quantify the genetic contribution of disease risks in the general population. By and large, we live with the tacit belief that basic principles, once found, will be simple and elegant, and that we can build Systems Biology from the ground level. This leads to a pointillistic research culture, as when we try to explain the heredity of complex traits by summing up the individual actions of millions of DNA variants, or when we look for the neural basis of behavior by the connectivity and firing patterns of millions of neurons.
I will use this talk to share some thoughts on the emerging appreciation that, in biomedical data science, perhaps the best one can learn is not widely generalizable Mechanisms, but different laws for different scales of organization. There may not be a good chance, and perhaps no need, to "know" a system by brute force accumulation of larger and larger data at the bottom level. Acknowledging the irreducibility of highly-level phenomena in biology and medicine can help us appreciate the distinct methods, norms, and compromises in traditional disciplines, and steer the society's investment towards balanced collection of good data on all levels. By giving up the blind celebration of sample size, we give more attention to new technologies that can measure what was previously inaccessible, and to the next-generation of information science that embraces messy, context-specific models.

Chimeric antigen receptor (CAR) T-cell therapy has shown dramatic clinical responses in hematologic malignancies, with a high proportion of durable complete remissions elicited in leukemia and lymphomas. However, achieving the full promise of CAR T-cell therapy, especially in solid tumors, will require further advances in this form of cellular therapy. A key challenge is maintaining a sufficient pool of functional CAR T cells in vivo. We recently developed a strategy to target vaccines to lymph nodes, by linking peptide antigens to albumin-binding phospholipid-polymers. Constitutive trafficking of albumin from blood to lymph makes it ideal chaperone to concentrate these “amphiphile-vaccine” molecules in lymph nodes that would otherwise be rapidly dispersed in the bloodstream following parenteral injection. These lipid-polymer conjugates also exhibit the property that they insert in cell membranes on arrival in lymph nodes. Here, we generated amphiphile CAR T ligand (amph-ligand) vaccine by exploiting these dual lymph node targeting and membrane-decorating properties to repeatedly expand and rejuvenate CAR T cells through the chimeric receptor in native lymph node microenvironment. We evaluated this approach in the presence of a complete host immune system. Amph-ligand vaccine boosting triggered massive CAR T expansion, increased donor cell polyfunctionality, and enhanced anti-tumor efficacy in multiple immunocompetent tumor models. We demonstrate two approaches to generalize this strategy to any CAR, enabling this simple HLA-independent vaccination approach to enhance CAR T functionality to be applied to existing CAR T cell designs. Taken together, our amph-ligand vaccine provides a simple engineering solution to augment CAR T-cell therapy.

Investigation of the molecular basis of a complex biological system, such as the brain, can lead to fundamental understanding of its composition and function, and to a new strategy to repair it. Such investigation, however, requires a tool that can capture biological structures and their molecular constituents across multiple orders of magnitude—from nanometers to centimeters—in length. Electron microscopy offers nanoscopic resolution but lacks molecular information to differentiate endogenous biomolecules as well as imaging speed to cover millimeter-scale specimens. Light microscopy provides molecular contrast but is limited by optical diffraction and the tradeoff between imaging speed and photobleaching.

In this talk, I will first introduce an optical imaging pipeline named expansion lattice light-sheet microscopy (ExLLSM) and its application to multiplexed, volumetric imaging of molecular constituents in cells and intact tissues. Using ExLLSM, our study has revealed molecular-specific structures of organelles, synapses, myelin sheaths, and neurites in rodent and insect brains at ∼60 by 60 by 90 nm effective resolution across dimensions that span millimeters. Next, I will present two recently developed methods that further extend the resolution and throughput of ExLLSM: (1) a non-radical hydrogel chemistry that forms a homogenous polymer network and physically separates biomolecules or fluorescent labels up to 40-fold linearly, and (2) a multi-modal optical microscopy that enables rapid, high-resolution imaging of both expanded and live tissues. Lastly, I will discuss the significance of these imaging methods in the context of microanatomy and functional omics.

The notion of building artificial human organs has moved from a far-fetched concept to the forefront of regenerative medicine research. While progress is being made, most tissues created to date are simply not large enough to support clinically meaningful functions, and their structural features remain an magnitude coarser in resolution than native tissues. Few organs better represent this challenge than the liver – the largest visceral organ in the human body, in which hepatocytes are aligned in single cell-width structures entangled with vascular and biliary networks. To address this challenge, we are working to develop a portfolio of tools that integrate 3D printing, synthetic biology, and the innate capacity of cells to self-assemble. We are applying these tools to decode the signals that drive tissue assembly during development, and using this information to build scaled artificial tissues that replicate the features of native tissues.

Abstract

Electromagnetic fields represent a fundamental aspect of nature, and serve as the primary carrier of energy. New abilities to control electromagnetic fields, as enabled for example by the developments of metamaterials and nanophotonic structures, can therefore have profound implications for energy technology. In this talk we will discuss some of our recent efforts in applying the concepts of electromagnetics towards developing new energy technologies, with examples including radiative cooling, and robust dynamic wireless power transfer.

Abstract:
Since the 1970s, the semiconductor industry has fabricated electronic circuits using a plasma based pattern-transfer ap-proach that is remarkably reminiscent of the etching artform used centuries ago. Only now, the patterns are a million times smaller and driven by the wafer fab equipment industry. The most advanced plasma etching technique in production today is called atomic layer etching (ALE) in which a single layer is removed in a cyclic manner. This talk will review the ALE ap-proach in comparison to conventional plasma etching tech-niques, such as Reactive Ion Etching (RIE). As RIE reaches its fifth decade, its drawbacks have become apparent. ALE offers better control by isolating steps in time and switching between the steps in a repeatable cycle. To the extent that an ALE pro-cess behaves ideally – with high ALE synergy and self-limiting behavior – the primary benefit is improved uniformity across all length scales: at the surface, between different aspect rati-os, and across the full wafer. Another benefit that will be high-lighted is the atomic-scale smoothness in topography of the surface left behind after etching. The underlying mechanism and benefits of plasma ALE will be described, providing insight into the plasma science behind the ancient art of etching. Overall, ALE is simpler to understand than conventional plasma etch processing, and is proving to be important as we apply the art of etch at the atomic scale.

Abstract

Future applications, such as wearable electronics, flexible and transparent displays, or devices for solar energy conversion and storage require materials with more versatility, more integrated functions, and more environmentally responsible processing compared to traditional options (i.e., inorganic semiconductors, like silicon). Organic semiconductors, such as small molecules and polymers, are well-suited to these future requirements; however, their electrical properties and environmental stability are inherently worse. Hybrid materials, such as inorganic nanoparticles embedded within a polymer film, can mitigate the trade-offs that exist for any single material type by combining organic and inorganic semiconductors. For example, hybrid materials can impart multi-functionality, flexibility, transparency, and sustainability to devices based on the interaction of light and matter (i.e., optoelectronic devices) or energy-related devices (e.g., solar cells, supercapacitors, or photo-electrochemical cells). A critically important requirement to realize the promise of hybrid materials for devices is to understand and control thin film deposition. Because hybrid materials are heterogeneous systems containing more than one component, thin-film deposition can be complicated compared to single component films. As a result, the co-deposition of two or more materials with different properties to synthesize a hybrid film with pre-determined functionality is a technological challenge within thin-film engineering. I will describe my research program that investigates hybrid thin film deposition using resonant infrared, matrix-assisted pulsed laser evaporation (RIR-MAPLE) to control structure and properties and to improve the performance of optoelectronic and energy-related devices. I will also reflect on my path to a career in academia and the lessons I have learned along the way.

The majority of the population will experience low back pain in their lifetime. Degeneration of the intervertebral disc is highly correlated with low back pain, however, not all disc degeneration is painful. One of the most common forms of low back pain is disc-associated low back pain in which pain originates from intervertebral disc. In disc-associated low back pain, nerve fibers penetrate the previously aneural disc, where they are then thought to be stimulated by the harsh catabolic environment. Repetitive stimulation of these nerve fibers can cause sensitization and chronic pain. The overarching goal of our work is to engineer biomaterials that target these two key areas of disc-associated low back pain: nerve growth and stimulation. Current clinical treatments for chronic low back pain have limited efficacy or are highly invasive. The majority of research to date focuses on regenerating a young healthy disc. We believe our approach to target nerve growth and stimulation independent of disc regeneration has the potential shift the paradigm in the treatment of low back pain.

Abstract:
The experimental and computational investigation of both equilibrium and non-equilibrium strongly coupled systems with partially or fully degenerate electrons is an intellectu-ally stimulating and scientifically challenging problem. Warm dense matter (WDM) is of particular interest since it “exists in the lower-temperature portion of the high energy density (HED) regime, under conditions where the assumptions of both condensed-matter theory and ideal-plasma theory break down, and where quantum mechanics, particle correlations, and electric forces are all important.” [FESAC 2009]. Interiors of giant planets, brown dwarfs, and neutron star envelopes are all examples of WDM. A wide variety of theoretical methods have been developed and are in routine use for studying warm dense matter. This includes density functional theory, time-dependent density functional theory, and quantum kinetic theory. Recently, there has been a resurgence in interest in using a “simpler” approach to investigating WDM based on quantum hydrodynamics. Quantum Hydrodynamics (QHD) has a long and interesting history, dating back to the first developments by Madelung and Bohm. In this talk, we discuss the historical and recent developments in QHD as applied to quantum many-body systems relevant to HED regimes. Recent work involving adding a QHD capability to the radiation hydrodynamics code MIRANDA will be discussed with applications to the electron gas.

Abstract:
NASA Heliophysics research studies a vast system stretching from the Sun to Earth to far beyond the edge of the planets. Studying this system – much of it driven by the Sun’s constant outpouring of solar wind – not only helps us understand fundamental infor-mation about how the universe works, but also helps protect our technology and astronauts in space. NASA seeks knowledge of near-Earth space, because, when extreme, space weather can interfere with our com-munications, satellites and power grids. The study of the Sun and space can also teach us more about how stars contribute to the habitability of planets through-out the universe.
Mapping out this interconnected system requires a holistic study of the Sun’s influence on space, Earth and other planets. NASA has a fleet of spacecraft stra-tegically placed throughout our heliosphere – from Parker Solar Probe at the Sun observing the very start of the solar wind, to satellites around Earth, to the far-thest human-made object, Voyager, which is sending back observations on interstellar space. Each mission is positioned at a critical, well-thought out vantage point to observe and understand the flow of energy and particles throughout the solar system, and all helping us untagle the effects of the star we live with.

Abstract:
As a fundamental process for converting kinetic to thermal energy, collisionless shocks are ubiquitous throughout the heliosphere and astrophysical systems, from Earth’s magnetosphere to supernova remnants. While these shocks have been studied for decades by spacecraft, telescopes, and numerical simulations, there remain key open questions in shock physics, such as: How do shocks accelerate particles to extremely high energies? or How are particles heated across a shock? Laboratory experiments thus provide a significant opportunity to both complement spacecraft and remote sensing observations with well-controlled and well-diagnosed datasets, and to help benchmark numerical simulations that bridge laboratory and astrophysical systems.
In this talk, I will discuss recent results from experiments and simulations on the formation and evolution of collision-less shocks created through the interaction of a supersonic laser-driven magnetic piston and magnetized ambient plas-ma. Through advanced diagnostics a fast, high-Mach-number shock is observed. Direct probing of particle velocity distributions reveals the coupling between the piston and ambient plasmas that is a key step in forming magnetized collisionless shocks. Particle-in-cell simulations further detail the shock formation process, the role of collisionality, and the dynamics of multi-ion-species ambient plasmas. I will also discuss how this experimental platform complements spacecraft missions and can allow novel investigations of shock heating and particle acceleration.
