Bernardo is a PhD student in mechanical engineering whose research examines the synthesis of robust strategies for grasping and dexterous manipulation. Specifically, he is examining the problem of caging, a geometric property by which a set of fingers manipulate an object by trapping it rather than immobilizing it. He has developed an explicit optimization approach to formulate the caging condition as a convex mixed-integer optimization problem. This was the first of its kind, since caging had previously been approached as either a topological or computational geometry problem. More recently, he has extended the formulation to synthesizing grasping strategies with certificates of correctness, a problem that is of high interest today both in academia and industry. He uses MATLAB’s Robotics Toolbox, Optimization Toolbox, and Deep Learning Toolbox as the main prototyping interface. In addition, his work has resulted in several tools that have been made open to the robotics and MathWorks communities, including ABB ROS Interface, Contact-TrajectoryOptimization Models, and Certified Grasping Toolbox. Bernando earned a BSc in electronics engineering from Universidad Simón Bolívar, Venezuela

Nicolas is a PhD student in electrical engineering and computer science whose research focuses on medical imaging technology. He is trying to solve challenging MRI problems by creating and distributing the hardware and computational tools needed for simultaneous optimization of coil geometries, encoding field patterns, and received-signal reconstruction algorithms. He has observed that the steps, or modules, that make up most MRI sequences often have conflicting patient-specific field pattern requirements. Nicolas developed a general MATLAB-based framework for use at scan time that optimizes the field patterns for each sequence module. The framework reads patient rapid-scan data from the imager, exploits the coil pre-characterization and convex formulations to efficiently compute sets of sequence-module optimized coil currents, and then transfers the coil currents sets, along with triggering conditions, to the coil driver array. Nicolas earned an SB in electrical engineering from MIT.

Ximo is a PhD student in aeronautics and astronautics conducting research at the intersection of numerical modeling and physics of nanoscale engineering devices. A frequent MATLAB user, he is working on a problem related to the numerical analysis of the shapes of small liquid menisci stressed under very high electric fields to evaporate ions. As these ions fly away, they produce thrust, hence a rocket can be constructed under this principle. This is difficult to analyze since the scales change dramatically from millimeters to nanometers, which creates a set of numerical challenges as equations describing the balance of electric, surface tension, and hydraulic stresses, including thermal loads that need to be solved simultaneously on meshes with very strong dimensional gradients. He earned a BS in aeronautics and astronautics and physics from Universitat Politècnica de Catalunya, Spain

Hannah is a PhD student in mechanical engineering whose research is centered on the fundamental design, optimization, and device integration of dynamically reconfigurable micro-scale fluid droplet morphologies for biomedical sensing and imaging. Being able to determine whether bacteria are alive or dead has important implications for rapid detection of pathogenic bacteria presence and the quantification of antibiotic effectiveness. This can be accomplished through sensing optical changes.Hannah is advancing sensing concepts that are based on employing micro-scale, bi-phase emulsion droplets for the optical quantification of bacteria motion to readily distinguish between live and dead bacteria. MATLAB is critical for in-situ assessment of the droplets’ optical characteristics and for computational deduction of the underlying bacteria dynamics. If successful, her approach, which involves efficient data capture and analysis enabled by MATLAB, will address drawbacks in sensitivity, delay times, and cost of bacterial culture and polymerase chain reaction approaches, given that her detection strategy is rapid and the required fluid morphologies are relatively inexpensive to fabricate. Hannah earned a BS in mechanical engineering from Schreyer Honors College at Pennsylvania State University.

Abinash is a PhD student in the Department of Materials Science and Engineering. His research involves atomic-scale characterization of materials using scanning transmission electron microscopy (STEM). He focuses on two aspects of electron microscopy: developing new tools for acquiring high quality data; and extracting local chemical and structural information in materials, using various statistical tools. With the discovery of aberration correctors for electron microscopes, acquiring images of various materials at anatomic scale has become common, yet extracting quantitative information from such images is still challenging. Abinash has implemented a revolving STEM based approach to simultaneously acquired images to correct drift and scan distortions in the musing MATLAB programs.Further, he uses correlation analysis to determine various inhomogeneities, like chemical and structural ordering, which drive the unique spatial pattern in polarization leading to the relaxor behavior. He also applies learning tools like convolutional neural networks for obtaining information, like sample mistilt and thickness, from position averaged convergent beam electron diffraction (PACBED) patterns.He also uses MATLAB to automate the process of generation of simulated PACBED patterns and applied image augmentations for neural networks.

David is a PhD student in computer science and a member of the Geometric Data Processing Group. His current research focuses on the hexahedral (hex) meshing problem, which is of interest for applications, including fluid and nonlinear elastic simulations. Automatically computing high-quality hex meshes is a significant problem largely due to the complicated topology of hex mesh singularities, regions of a mesh for which the combinatorial structure is irregular. David’s research addresses challenges through the lens of smooth geometry. The field-based meshing research program replaces the hard combinatorial problem of hex meshing with computing a smooth volumetric frame field, encoding the alignment of the mesh elements with the ultimate aim of recovering a mesh from the field. While frame fields take values in nonlinear, non-convex algebraic spaces (the octahedral and odeco varieties), he has studied the geometry of these spaces and developed manifold-based optimization methods tailored to the frame field problem. He has created aMATLAB toolkit, ARFF, which allows him to experiment directly with high-dimensional spaces and complex topologies.David earned anAB in computer science from Harvard University and anMAS in mathematics from University ofCambridge, England.

Ryan is a PhD student in mechanical engineering whose research is focused on the development of in-situ instrumentation and measurement techniques for end-to-end interrogation of selective laser melting (SLM) additive manufacturing. He has designed, built, and integrated two optical instruments with an SLM testbed: a mid-wave infrared (MWIR) camera that images thermal (blackbody) radiation from the build area and a near IR (NIR) pyrometer that measures the temperature of material directly at the laser’s focus. Determining the mathematical correspondence between a process signature and a component property (e.g. thermal radiance and density, respectively) is established by geometrically aligning the datasets using a metric of cross-predictive power between the datasets known as mutual information (MI). He is using the Signal Processing Toolbox to relate different process signatures to SLM component properties, including density, metallurgical grain size, and residual stress.

Charles is a PhD student in the Department of Electrical Engineering and Computer Science. His research interests include nanophotonics, light-matter-free-electron interactions, machine learning, complexity theory, quantum electrodynamics, and electron beam physics. His research contributions include the demonstration of novel nanophotonic light sources driven by free electrons, photonic computing architectures for complex optimization, and photonic devices to control light at the nanoscale (called metasurfaces). The MATLAB interface—enabling the simultaneous writing of scripts, decoding, evaluating variables in the command line, and plotting—has been instrumental in the design and analysis of his work on polarization-insensitive dielectric-based metasurfaces and on light emission from all-silicon substrates. In particular, MATLAB’s library of optimization algorithms proved extremely helpful in the correction of chromatic aberrations in dielectric metasurfaces, since the design of such metasurfaces requires the optimization of a complicated constraint function at various wavelengths of operation. More recently, he developed an algorithm called the Photonic Recurrent Ising Sampler (PRIS) that can solve NP-hard optimization problems by performing iterative matrix multiplications. While working on the experimental demonstration of the proposed concept with photonic components, he relied on MATLAB’s computational speed for large-scale matrix multiplications to numerically investigate the performance of the algorithm.

Lluís is a PhD student in civil and environmental engineering studying geologic CO2 storage (GCS). GCS is the second stage of a technology known as carbon capture, utilization, and storage, a leading climate change mitigation technology and an enabling application for other negative-emissions technologies. Through a combination of geologic and multiphase flow modeling, he is addressing the critical question of migration and potential leakage of CO2 through faults during CO2 storage in sedimentary formations. Lluís is developing all of this research using MATLAB, ranging from visualization to sophisticated developments for the simulation of multiphase flow (governed by complex coupled PDEs) in multimillion-cell grids. In particular, he is a regular user of the MATLAB Reservoir Simulation Toolbox, to which he is also a contributor. Lluís is currently developing physics-based, probabilistic and machine-learning tools for the upscaling of fault properties and quantitative hazard assessment of CO2 migration through faults. Lluís earned a BS in geology from Universitat de Barcelona, Spain and an MS in geotechnical and earthquake engineering from Universitat Politècnica de Catalunya, Spain.

Rohit is a PhD student in mechanical engineering developing continuum mathematical models for the collective dynamics in biological and engineered active fluids—for example, suspensions of swimming cells or self-propelling colloidal particles. In particular, he is developing and investigating physics-informed machine learning methods to infer partial differential equations that govern macroscopic observables directly from particle data. To achieve this, Rohit has used MATLAB for building a learning framework that coarse-grains microscopic data and results in interpretable models that are essential for predicting the complex dynamics in these systems. He has also extensively used MATLAB as a teaching tool in his role as a TA for a graduate subject in fluid mechanics, as well as an undergraduate subject in dynamics and controls. He earned a BTech in mechanical engineering from Indian Institute of Technology, India and an SM in mechanical engineering from MIT.

Wenhui is a PhD student in mechanical engineering whose research focuses on the spatial and temporal self-organization of multicellular living systems in 3D during physiological and pathological processes. She uses modern microscopy to image in real time the 4D spontaneous organization of living cells and under various conditions, including different surrounding matrix mechanics and substrate curvature. Using MATLAB, she can extract data from microscopic videos and images and convert the optical intensity information into cell positions as a function of time. She also calculates the multicellular flow field such as swell/shrink, rotation and shear to understand how multicellular system dynamics changes as substrate curvature changes. Based on cell positions in 3D, she uses MATLAB code to perform Voronoi tessellation of cells on a spherical surface that can be used to reveal the cell packing behavior during human lung alveolar development. Wenhui earned a BEng from Xi’an Jiaotong University, China and an SM from MIT.

Huanhuan is a PhD student in chemical engineering. She is working on shock electrodialysis (shock ED), a new electrochemical process for water treatment that was designed and developed by the Bazant Research Group. Recent experimental results shows that shock ED can selectively remove multivalent cations, which could be promising for continuous and economical heavy metal ion removal from drinking water and industrious waste. For instance, preliminary results showed that shock ED can almost completely remove lead ions (Pb++) from model Flint tap water (mostly NaCl) from unsafe levels (up to 50ppb) down to <1ppb, well below the EPA action limit of 15ppb, in a point-of-use small-scale device with an operating electrical cost of only pennies per meter cubed of fresh water, compared with $25/m³ for existing (impractical) filtration methods. This new technology could have a significant impact on human health in the U.S. and around the world. She is using MATLAB to study PDE-based models of shock ED from experimental data (including her own) on selective ion removal. Her innovative work with MATLAB could lead to new simulation tools for electrochemical systems involving charged porous media and membranes, including (but not limited to) water treatment applications. Huanhuan earned a BEng and SB in engineering mechanics, both from Tsinghua University, China.
