\"\"Remote Estimation of Above Ground Forest Biomass<\/h2>\n

Collaborators: Drs. Husnu S. Narman and Rick Gage<\/p>\n

Abstract: This study explores a modern approach to estimating forest biomass using drone imagery, satellite LiDAR, and machine learning. Traditional biomass measurement methods are labor-intensive and slow, prompting the need for scalable, remote techniques. Researchers developed models to identify tree species and estimate biomass based on canopy size and height, even in areas with limited ground-truth data. Early results show promise, especially in open forest regions, though more data is needed for dense environments. The project highlights the potential of combining accessible technologies with AI to monitor forest health and carbon stocks, contributing to climate change research and environmental management.<\/p><\/div><\/div>\n<\/div>\n

\"\"Blood-Based RNA Biomarkers of Alzheimer\u2019s Disease and Related Dementia<\/h2>\n

Collaborators: Drs. Joon W. \u201cSimon\u201d Shim, Courtney Wellman, and Todd Davies<\/p>\n

Abstract: Dr. Joon W. \u201cSimon\u201d Shim\u2019s research investigates blood-based RNA biomarkers that can enable early and noninvasive detection of Alzheimer\u2019s disease (AD) and Parkinson\u2019s disease dementia (PDD). Building on recent discoveries from postmortem brain transcriptomic analyses, his team found that hemoglobin genes (HBA1, HBB) are significantly reduced in Alzheimer\u2019s and Parkinson\u2019s tissues, suggesting a novel link between impaired oxygen transport, hypoxia, and cognitive decline.
\nThe project aims to determine whether these brain-specific RNA changes are also detectable in peripheral blood of living patients and to examine how they relate to systemic oxygen saturation. Using quantitative RT-PCR and pulse co-oximetry, the study will analyze blood samples from patients with AD, PDD, and cognitively normal controls.
\nThis research bridges biomedical engineering, neuroscience, and geriatric medicine to identify molecular signatures that reflect both neural and systemic health. If successful, the findings could lead to accessible diagnostic tools for early detection and personalized intervention\u2014such as oxygen-based therapies\u2014to slow or prevent cognitive decline in aging populations.<\/p><\/div><\/div>\n<\/div>\n

\"\"Implant Fabrication Using Advanced Manufacturing Techniques for Bone Tissue Engineering <\/h2>\n

Dr. Ross Salary <\/p>\n

This project is supported by the National Aeronautics & Space Administration (NASA) under Award Numbers 80NSSC22M0249 and 80NSSC19M0054, focuses on implant fabrication using advanced manufacturing techniques for bone tissue engineering in collaboration with the School of Medicine at Marshall University. This multidisciplinary project integrates mechanical engineering, biomedical science, and artificial intelligence (AI) principles to address one of the most pressing challenges in regenerative medicine, i.e., designing and fabricating patient-specific bone implants that can effectively support and stimulate tissue regeneration. The research problem at the core of this project arises from the complex and interdependent influences of material, process, and biological factors on implant performance. Despite significant advancements in scaffold design and fabrication, it has remained largely unknown how these factors collectively determine the structural integrity, mechanical functionality, and osteogenic (bone-forming) potential of the resulting implants. Variations in material composition, fabrication parameters, pore geometry, and cell-related factors can significantly impact the biological response, potentially leading to inconsistencies in bone growth and integration. Therefore, there is a need to identify the fundamental mechanisms and underlying relationships that govern scaffold fabrication, osteogenesis (bone formation), and ultimately, the fracture-healing process. By identifying and investigating these relationships through experimental characterization and computational modeling, this project aims to establish predictive frameworks and design principles that enable the fabrication of patient-specific bone implants. The outcomes of this project are expected to advance the frontier of bioprinting technologies and contribute to the development of self-healing and clinically viable bone implants that improve recovery outcomes for patients with complex injuries or defects<\/p><\/div><\/div>\n<\/div>\n

\"\"The Investigation of Aerosol Formation, Transport, and Deposition in (AJP) for High-Resolution Fabrication of Electronic Devices <\/h2>\n

Dr. Ross Salary <\/p>\n

This project is supported by the National Science Foundation (NSF) under Award Number OIA-2327460 and by the National Aeronautics & Space Administration (NASA) under Award Number 80NSSC24K0607, focuses on the investigation of aerosol formation, transport, and deposition in aerosol jet printing (AJP) for high-resolution fabrication of electronic devices. AJP is a direct-write additive manufacturing technique that enables maskless, non-contact fabrication of a broad spectrum of electronics, including sensors, transistors, antennas, and optoelectronic devices, on both planar and three-dimensional surfaces. Despite these advantages, AJP is highly complex and sensitive to subtle variations in process conditions. AJP often suffers from gradual drifts in aerosol transport and deposition, resulting in inconsistencies and defects that compromise the dimensional accuracy and functional performance of printed electronic devices. Therefore, there is a need to identify and characterize the underlying aerodynamic phenomena that govern aerosol flow dynamics in AJP. This project aims to uncover and elucidate the key mechanisms behind aerosol generation, transport, and deposition in AJP through computational fluid dynamics (CFD) modeling, experimental validation, and AI-driven modeling. Overall, this project will enable high-resolution, defect-free fabrication of electronics, advancing precision, reliability, and miniaturization in electronics and semiconductor manufacturing.<\/p><\/div><\/div>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":720,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"page-legacy.php","meta":{"_acf_changed":false,"footnotes":""},"class_list":["post-12404","page","type-page","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.marshall.edu\/cecs\/wp-json\/wp\/v2\/pages\/12404","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.marshall.edu\/cecs\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.marshall.edu\/cecs\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.marshall.edu\/cecs\/wp-json\/wp\/v2\/users\/720"}],"replies":[{"embeddable":true,"href":"https:\/\/www.marshall.edu\/cecs\/wp-json\/wp\/v2\/comments?post=12404"}],"version-history":[{"count":21,"href":"https:\/\/www.marshall.edu\/cecs\/wp-json\/wp\/v2\/pages\/12404\/revisions"}],"predecessor-version":[{"id":16403,"href":"https:\/\/www.marshall.edu\/cecs\/wp-json\/wp\/v2\/pages\/12404\/revisions\/16403"}],"wp:attachment":[{"href":"https:\/\/www.marshall.edu\/cecs\/wp-json\/wp\/v2\/media?parent=12404"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
