Co-Is: Xiang Zhang, PhD, Research Scientist/Technical Lead, Center for Clinical and Translational Research, Massachusetts Institute of Technology; Evan Linton, MS, Clinical Research Scientist, Center for Clinical and Translational Research, Massachusetts Institute of Technology
Description: This project addresses the translational gap in neonatal care by validating and developing non-contact monitoring devices that cater to the unique physiology of neonates. Through a collaborative effort involving the MIT Center for Clinical and Translational Research (CCTR) and he Neonatal Intensive Care Unit (NICU) at Tufts Medical Center, novel radar and camera technologies will be compared with standard monitoring equipment in a clinical setting. A prototype combining these technologies will be designed and tested on infant simulators, potentially transforming neonatal monitoring practices and benefiting NICU personnel, patient families, and device innovators.
Optimization of Handheld 3D Ultrasound and Photoacoustic Imaging for Addressing Healthcare Disparities
PI: Srivalleesha Mallidi, PhD, Assistant Professor, Department of Biomedical Engineering, Tufts University School of Engineering
Description: The research aims to optimize a novel, cost-effective 3D ultrasound and photoacoustic imaging (USPAI) system that promises to make real-time 3D imaging more accessible across diverse patient populations. By focusing on improving the system’s performance for varying skin melanin and subcutaneous fat content, and ensuring consistent imaging results across different operators, the project seeks to address healthcare disparities. The outcome could significantly broaden the reach of 3D imaging technology, enhancing its applicability in various medical contexts.
Validation of a Remote Speech/Motor Assessment Protocol for Neurodevelopmental Disorders
PI: Karen Chenausky, PhD, CCC-SLP, Assistant Professor, Department of Communications Sciences and Disorders and Director, Speech in Autism and Neurodevelopmental Disorders (SPAN) Laboratory, MGH Institute of Health Professions

Description: The research seeks to develop and test innovative access technologies for augmentative and alternative communication (AAC) devices, specifically targeting non-speaking autistic individuals. By engaging with stakeholders and conducting a needs assessment within the nonspeaking autism community, the project aims to create more inclusive and symmetric communication tools. Prototype technologies will be evaluated, with the goal of advancing one for further development. This work has the potential to significantly enhance AAC technology, offering new means of engagement for those currently underserved by existing systems.
Next-Generation Nerve Repair: Combined Magnetic and Topographic Cues for Highly Directed Neurite Outgrowth
PI: Abigail Koppes, PhD, Associate Professor, Department of Chemical Engineering, College of Engineering, Northeastern University
Co-PIs: Ryan Koppes, PhD, Assistant Professor, Department of Chemical Engineering, College of Engineering, Northeastern University; Laura Lewis, PhD, Distinguished University and Cabot Professor, Department of Chemical Engineering, Department of Mechanical and Industrial Engineering, Northeastern University
Description: The project aims to advance therapies for peripheral nervous system (PNS) injuries by combining tissue engineering and materials science to explore magneto-stimulation for nerve repair. Building on previous findings that static magnetic fields can direct neuron outgrowth, the research will investigate the use of magnetic and topographical cues to enhance nerve regeneration. This interdisciplinary effort, involving bioengineers, materials scientists, and neurobiologists, seeks to optimize conditions for clinical applications, transforming outcomes for patients with PNS injuries and advancing the science of translation.
Empirical Dynamic Modeling: A Path to Predicting Health Outcomes with Limited Data
PI: Benjamin Stern, DPT, Assistant Professor, Department of Public Health and Community Medicine, School of Medicine, Tufts University
Co-Is: Ethan Deyle, PhD, Research Assistant Professor, Department of Biology, Boston University; Ying-Cheng Lai, PhD, Regents Professor, School of Electrical, Computer and Energy Engineering, Arizona State University
Description: This project aims to apply a dynamical systems approach, originally developed for studying ecosystem dynamics, to the analysis of athlete health. By utilizing empirical dynamic modeling (EDM), the research seeks to identify causal relationships in biological time series, overcoming limitations of traditional methods such as correlation or regression. Seasonal data from 30 Division I athletes at UCSD will be analyzed, with the potential to advance understanding of complex biological interactions and improve health monitoring practices. Successful outcomes will be shared through a repository, offering code, instructions, and examples for broader application.
