• Radar Multichannel Beamforming with MIMO and non-MIMO Signal Processing
  • Pablo Badia, Electrical and Computer Engineering
  • Abstract: A MIMO-array is best understood as a signal processing technique involving multiple transmitters and multiple receivers operating independently to transmit orthogonal or otherwise distinguishable waveforms. The use of MIMO arrays in radars is novel since MIMO-arrays fundamentally change how radar systems transmit and process signals. Traditional radar systems transmit using all antenna elements in an array. A MIMO radar transmits using independently operating subarrays, which allows the receiver channels to distinguish the contributions of each transmit subarray. MIMO-arrays provide advantages to radar systems, including high angular resolution, improved target detection and discrimination, spatial diversity, and array geometry flexibility. However, there are drawbacks to using MIMO-arrays: limited beam-forming capabilities and higher signal processing complexities—including signal separation from different channels. Additionally, while MIMO-arrays generally reduce the need for beam steering hardware, having multiple processing chains can be expensive. MIMO-arrays and non-MIMO phased-arrays play different roles for communication and radar purposes. Non-MIMO phased arrays primarily focus on enhancing signal-to-noise ratio and electronic beam steering. MIMOarrays leverage waveform diversity and spatial multiplexing to achieve higher resolution, improved angle of arrival estimation, and increased target detection capabilities. The core problem this study intends to solve is to understand the things needed to be considered when performing multichannel beamforming techniques with either MIMO or non-MIMO approaches for different radar modes and from different platform perspectives.
• Robust Noise Attenuation via Adaptive Pooling of Transformer Outputs
  • Greyson Brothers, Engineering for Professionals
  • Abstract: How do self-driving cars identify what is important, like picking out a pedestrian from a sea of vehicles? Many modern AI systems use transformer models, which condense many pieces of data into one meaningful summary. This step, called pooling, is critical for making decisions. But in real-world tasks, where much of the data is distracting or noisy, common pooling methods like averaging or picking the strongest signal may not work as intended, causing our self-driving car to ignore that stray pedestrian. Our paper shows that these pooling methods do indeed fail when there’s a large number of distractions. We then predict that a lesser-known technique, called adaptive pooling, can prevent such a performance collapse, even in the presence of many distractors. It does this by using attention to learn which parts of the input matter and what to ignore, like tuning out a noisy crowd to listen to a single voice. Our findings demonstrate that adaptive pooling can closely match the best possible summary of the inputs. More importantly, we show that simply swapping out the old methods for adaptive pooling can significantly improve the reliability and trustworthiness of transformer-based models in many applications, even when their inputs are quite messy.

• Space Weather and Lunar EVA Spacesuits
  • Talia Elkhatib, Space Systems Engineering
  • Abstract: This project aims to understand and mitigate the effects of space weather to support safe and sustainable lunar extra-vehicular activity (EVA). With no natural protection from solar radiation or cosmic rays, the Moon presents significant challenges to astronaut health and equipment longevity. We assess space weather data, define acceptable radiation exposure levels, and propose key radiation shielding features for EVA spacesuits.
• A Wearable Fluorescent Biosensor Patch for Real-Time Hydration and Electrolyte Monitoring Access Across Diverse Populations
  • Raven Holston-Turner, Applied Science Program, Engineering for Professionals
  • Abstract: Dehydration and electrolyte imbalance are critical risks for patients (ICU, elderly, pediatrics), athletes, military personnel, and workers in extreme environments. Current hydration monitoring relies heavily on delayed blood/urine tests or subjective assessments. We propose a non-invasive, low-cost optical biosensor patch that provides continuous, real-time hydration and electrolyte data.
• Strength in Numbers: Measuring Hand Function Through a Portable Device
  • Maya Lane, Physical Medicine and Rehabilitation
  • Abstract: My research studies how commonly used clinical measures of hand control in stroke patients relate to lift and grip force measured by a portable device (SenseHand). The long-term goal is to develop new methods to assess hand recovery status using portable remote devices that can be used in the clinic and at home.
• Clear-SiR for Deep Raman Biomolecular Sensing
  • Michael Lee, Mechanical Engineering
  • Abstract: Novel engineered pathway that bridges Raman spectroscopy to non-invasive clinical diagnosis
• Generalized Category Discovery for Time-Series Applications via Koopman Operator Feature Representation
  • Daniel Peterson, Applied Science Program, Engineering for Professionals
  • Abstract: Generalized category discovery of time-series data is challenging because of the temporal complexity of the data. Koopman operator theory has been shown to be effective for extracting informative features from time-series data for various machine learning tasks. Although it has been applied to clustering, forecasting, anomaly detection, and classification, its use in generalized category discovery remains unexplored. We propose a Koopman-based approach to generalized category discovery using dynamic mode decomposition (DMD) to extract a low-dimensional and interpretable feature embedding from time-series data. We show that this approach can extract meaningful structure from time-series data, enabling generalized category discovery. A comparative study across several dynamical systems highlights the advantages of using Koopman-based methods for feature extraction over other feature extraction methods.
• Synthesis and Characterization of WO3 and MoO3 in Polymer Matrix Nanocomposites
  • Duaa Ramadhan, Materials Science and Engineering
  • Abstract: Tungsten oxide (WO3) and molybdenum oxide (MoO3) are photochromic materials that change color upon going from one oxidation state to another by absorption of ultraviolet light, and these types of materials have applications in areas such as displays, imaging devices, “smart windows,” and solar energy conversion. In this work, a method based on chemical vapor deposition (CVD) was used for in situ growth of tungsten oxide (WO3) and molybdenum oxide (MoO3) nanoparticles in polydimethylsiloxane (PDMS) and in poly(tetrafluoroethylene-co-hexafluoropropylene) (also known as fluorinated ethylene propylene or FEP). The resulting polymer matrix nanocomposites (PMNCs) display a range of interesting and useful, photochromic and photocatalytic behaviors related to the properties of the particles present in the matrix. To synthesize WO3-FEP, WO3-PDMS, MoO3-FEP, and MoO3-PDMS PMNCs, the polymer matrix and an organometallic precursor were placed into a reaction vessel, the vessel was evacuated to the desired pressure, and then subjected to a two-step heating process. This process causes vaporization of the precursor, which diffuses into the matrix. Subsequent decomposition of the precursors results in nanoparticle growth. This synthesis method produces a homogeneous distribution of the nanoparticles throughout the polymer matrix [2]. WO3-FEP, WO3-PDMS, MoO3-FEP, and MoO3-PDMS, PMNCs were characterized using UV-Vis-NIR spectrometry and x-ray diffraction (XRD) to understand and analyze the optical and structural properties of the PMNCs. In particular, Tauc plot analysis was used to determine the bandgaps of these materials. Producing WO3-FEP, WO3-PDMS, MoO3-FEP, and MoO3-PDMS PMNCs with this synthesis technique can be used to produce materials for green energy applications.
• Embrace the Accelerated Frame of Reference

Tech Talk #1 – Dusty Descents: Fluid Dynamics of Ejecta and Multiphase Instabilities in Lunar and Martian Landings 

Rui Ni, Associate Professor, Department of Mechanical Engineering  

• Planetary landings on the Moon and Mars generate complex interactions between rocket exhaust plumes and unconsolidated regolith, leading to the mobilization of vast quantities of dust and granular ejecta. These interactions present both engineering hazards and scientific opportunities, influencing lander stability, surface modification, and environmental contamination. This talk presents recent advances in modeling and experimental studies of ejecta dynamics, with a focus on multiphase instabilities that arise during plume–surface coupling. High-speed imaging, scaling analyses, and computational fluid dynamics reveal the development of particle-laden shear layers, jet–particle interactions, and clustering phenomena that drive nonuniform dust transport. These mechanisms underpin the onset of coherent ejecta jets, turbulent entrainment, and lofting mechanisms that differ significantly between lunar vacuum conditions and the rarefied Martian atmosphere. By identifying the governing dimensionless parameters and instability pathways, this work advances predictive capabilities for future landing missions and supports the design of mitigation strategies to ensure safe and sustainable extraterrestrial operations.  

Tech Talk #2 – Generative AI: Understanding the Foundations, Opportunities, and Future Directions

Geetha Rajasekaran, Lecturer, Department of Computer Science, Engineering for Professionals 

• Generative AI has rapidly evolved from a research concept into a transformative technology reshaping organizations, academia, research, and everyday life. This talk traces the journey from classical Natural Language Processing (NLP) to Large Language Models (LLMs) built on Transformer architectures, providing a technical overview of how they are trained, fine-tuned, and aligned to generate coherent text and code. Building on that foundation, the talk will examine the concepts of Retrieval-Augmented Generation (RAG) for grounded answers, orchestration frameworks like LangChain for integrating tools and workflows, and the emergence of agentic AI capable of planning and acting autonomously. The discussion highlights opportunities across domains alongside key challenges such as hallucinations, bias, privacy, cost, and evaluation. The session concludes with future directions, including multimodal LLMs, efficient and edge inference, and responsible AI practices that enable trustworthy, high-impact deployments.
