Matthew Yeung is a PhD candidate whose research explores interactions between light and nanostructures for both fundamental research and the development of novel optoelectronic technologies. The focus of his current work, supported by a MathWorks Fellowship, is the development of nanostructured devices that can interact with and measure light fields with sub-femtosecond resolution. These devices enable a critical new tool in visible to near-infrared optical metrology: a sampling oscilloscope for light waves that could offer a fresh time-domain perspective on how light interacts with materials. Matthew’s work has a large number of potential applications, including creating more efficient solar cells, understanding the fundamental energy transfer mechanisms that enable photosynthesis, and characterizing materials with unprecedented sensitivity. MATLAB has been vital in Matthew’s device design, experiment development, and instrumentation interfacing, and he looks forward to sharing the resulting tools with the MathWorks community. His work has the potential to help usher in revolutionary advances in light-based technologies.

Li-Yu Yu is a PhD candidate whose research seeks to advance the growing field of spectroscopic microscopy, a powerful tool for delivering rich molecular information about an object through the measurement of its spatial and spectral characteristics. Potential applications of spectral microscopy range from medical diagnosis to pharmaceutical research and material identification. Lu-Yu’s current research, supported by a MathWorks Fellowship, addresses the crucial drawback of poor spectral signal-to-noise ratio in conventional dispersive spectrometers and limited spectral tuning capability in conventional laser sources. His goal is to develop a new spectroscopic measurement strategy that leverages illumination encoding and model-based AI to achieve broadband, real-time, super-resolved spatiospectral image reconstruction, offering a platform for advanced functional analysis in a sophisticated multicellular environment. MATLAB has been an essential tool in this work, enabling the simulation of optical physics, optimization, signal processing, and machine learning. Li-Yu’s work has the potential for far-reaching impact in the field of spectroscopic microscopy and could deliver useful new perspectives and open-source data processing tools (including tools to support a core data processing challenge of compressive sensing and spectral unmixing) to advance innovative research across the imaging and sensing, and signal processing communities.

Mingxin Yu is a PhD candidate whose research is in the fields of robotics and machine learning. As a MathWorks Fellow, Mingxin will contribute to a research program aimed at developing a learning-based method for accelerating motion planning in robot manipulation problems and will help to develop a proposed, new approach that leverages a machine learning-based control barrier functions (CBF) in safety-critical motion planning scenarios to tackle the high sampling complexity of traditional sampling-based motion planning methods. The principal aim of this project is to incorporate CBF into the traditional motion planning methods to steer the system to navigate safely to the goal, while significantly reducing time-consuming sampling tasks and maintaining the guarantees of the original methods. Mingxin’s research has the potential to offer valuable new solutions to a planning problem with significant impact on numerous real-world applications, including manipulation in cluttered environments, multi-arm assembly tasks, and human-robot interaction.

James H. Zhang is a PhD candidate whose research concentrates on efficient, economical strategies for desalinating water using porous, interfacial evaporators. This technology utilizes solar energy to evaporate water from brackish sources wicked inside of a interfacial evaporator. The vapor can then be collected and condensed into clean water. Specifically, James is exploring the thermodynamics of solar-driven evaporation inside porous materials, particularly in the case of super-thermal evaporation rates (2-3 times beyond the thermal limit), to optimize porous materials for use in desalination devices. He has designed a MATLAB-based model to investigate the evaporation process and identify key variables that could be manipulated to maximize evaporation rates. The model, combined with a MATLAB model of light-structure interactions developed by James’s mentee, has the potential to yield a comprehensive understanding of transport phenomena in porous evaporators. A MathWorks Fellowship will enable James to continue his research in super-thermal evaporation rates, which will be critical in the development of desalination technology and could help the growing global need for efficient clean water production.

Ruiqi Zhang is a PhD candidate whose research aims to develop novel solar cell technologies to support renewable energy. Specifically, he is devising machine learning (ML) algorithms to predict optimal structures for solar photovoltaic devices that utilize organic-metal-halide perovskites, a class of materials with promising optoelectronic properties for the next generation of solar photovoltaics.

His predictive work has demonstrated less than 5% between predicted outputs and ground truth performance—a remarkable indicator of potential success. Ruiqi’s work promises to enable rapid, targeted investigations of various novel perovskite compositions and identify the optimal compositions for perovskite solar structures. Ultimately, his work could represent a major step forward in solar energy, helping to meet the need for clean, renewable power.
