National Science Foundation Research Experience for Undergraduates (NSF REU)
Can functional ultrasound detect neural activity with better sensitivity than functional magnetic resonance imaging (fMRI)? How well can diffuse optical techniques detect breast cancer and monitor bone healing? Does combining machine learning with ultrasound allow better flow detection in smaller vessels or increase the speed of processing large echo datasets (gigabyte-sized)? Can cell imaging methods help researchers determine the mechanisms by which COVID-19 and SARS-CoV-2 induce cellular stress? Can GSP-based graph learning frameworks be used to estimate structural brain connectivity from functional signals measured by resting-state fMRI?
Diverse teams are needed to answer engineering questions like these. This Imaging in Medicine and Biology for Underrepresented Minorities REU site will provide an environment for underrepresented minorities (URM) undergraduates to complete individual research projects under the mentorship of leaders in their respective fields, in a world-class interdisciplinary research environment. The Imaging in Medicine and Biology for Underrepresented Minorities REU site will also provide structured enrichment programs to participants that will allow students to develop critical skills needed to be successful in STEM graduate education (GRE preparation, time management, oral/written presentation). The University of Rochester (UR) Hajim School of Engineering and University of Rochester Medical Center (URMC) is an ideal setting for this REU site; it is the home of the Rochester Center for Biomedical Ultrasound (RCBU), the Institute of Optics, the Goergen Institute for Data Science (GIDS), and the Del Monte Institute of Neuroscience—members of which will serve as mentors in this REU site.

2023 Projects (Planned)
Title: High-resolution functional ultrasound imaging based on ultrafast Doppler ultrasound
Mentor: Farran Briggs (Neuroscience)
High-resolution functional ultrasound imaging (fUS) is an innovative method to gather large neuron activity data sets throughout the brain of rodents, ferrets, and non-human primates. Students will use fUS to visualize neuronal activity in visual brain areas. They will explore the impact of cortical feedback to the visual thalamus and its functional pattern of activation. At the end of the 10-week research experience, students should be able to (a) use fUS to image the visual cortex and visual thalamus, (b) perform basic histological processing, and (c) compute power Doppler images from ultra-fast plane-wave images.
Title: Diffuse optical imaging for non-invasive deep tissue monitoring of bone healing
Mentor: Regine Choe (Biomedical Engineering)
Diffuse optical imaging can quantify hemodynamic parameters of deep-tissue in vivo samples non-invasively, enabling longitudinal monitoring of the bone graft vascularization process. The project will focus on developing and validating diffuse optical imaging methods. At the end of the 10-week research experience, students should be able to (a) perform 3D image reconstruction based on diffuse optical measurements, and (b) develop image processing methods to compare diffuse optical images and clinical images obtained using micro-CT, MRI, and ultrasound.
Title: Advancing high-frequency ultrasound imaging technologies to visualize and quantitatively monitor structural changes in tissue
Mentor: Diane Dalecki (Biomedical Engineering)
In this project, students will develop quantitative ultrasound imaging metrics to characterize collagen microstructure within tendon and use machine learning techniques to test these quantitative metrics as noninvasive indicators of disease or injury. At the end of the 10-week research experience, students should be able to apply (a) quantitative, high-frequency ultrasound imaging techniques to monitor cell migration or proliferation, and (b) machine learning techniques to quantitative ultrasound data.
Title: Imaging of virally induced exodosis
Mentor: Stephen Dewhurst (Microbiology and Immunology)
Students will use cell imaging methods to examine fundamental mechanisms by which human coronaviruses and SARS-CoV-2 induce cellular stress, and “ER exodosis” (i.e., the release of the protein contents of the endoplasmic reticulum from the cell). At the end of the 10-week research experience, students should be able to (a) determine whether the SARS-CoV-2 homologs of the genes shown to induce ER exodosis by SARS-CoV-1 (the “viroporins” E and 3a) are also able to induce ER exodosis, and (b) know how to examine protein assays from minimally pathogenic human coronaviruses.
Title: Functional ultrasound brain imaging via neurovascular and neuromechanical coupling
Mentor: Marvin Doyley (Electrical and Computer Engineering)
In this project the student will perform studies using high-frequency functional ultrasound (fUS) and high-frequency shear wave elastography (SWE) in the developing brains of murine models. Students will compute activation maps from fUS and SWE images obtained with auditory stimulation. Studies will also investigate if advanced machine learning techniques provide better activation maps and allow the detection of smaller vessels. At the end of the 10-week research experience, students should be able to perform ultrasound imaging, compute activation maps from ultrasound SWE and power Doppler data, and construct activation maps with different approaches including machine learning methods.
Title: Super-resolution imaging of vascular malformation development
Mentor: Angela Glading (Pharmacology and Physiology)
This project would require training in advanced optical imaging, and development of an analysis program to quantify protein co-localization. Students will perform transfection, confocal ratio-metric imaging (FRET or FLIM), and permeability measurements on primary endothelial cell cultures. At the end of the 10-week research experience, students should be able to perform staining, image acquisition, and contribute to analysis and subsequent creation of 3D models of the vascular tissue.
Title: Bioluminescence to imaging of tactile sensory perception
Mentor: Manuel Gomez-Ramirez (Brain and Cognitive Science)
In this project the students will use bioluminescence to study the role of excitatory vs. inhibitory cells in tactile sensory perception. At the end of the 10-week research experience, students should be able to perform bioluminescence imaging, headpost implant, and viral injection.
Title: Robot-assisted strain imaging
Mentor: Thomas Howard (Electrical and Computer Engineering)
In this project students will develop perception algorithms for robotically-assisted strain elastography, which uses a robotic arm to capture force and ultrasound measurements that are used to infer the stiffness and structure of underlying tissue. Students will use tissue models to evaluate the accuracy and quality of the resulting images and explore different organs such as the liver. Students will also learn software development and best practices for robotic systems. At the end of the 10-week research experience students should be able to calculate stiffness maps using strain imaging techniques with a robotic manipulator.
Title: Determination of 3-D scapular position from plain radiographs using computer vision
Abnormalities in scapular mechanics, or scapular dyskinesis, during shoulder motion negatively affects function. Diagnosis of scapular dyskinesis is important to guide treatment and improve patient outcomes but can be challenging to identify clinically. In this project, students will develop a computer vision algorithm to infer 3-D scapular position through interpretation of shoulder plain 2D radiographs. At the end of the 10-week research experience, students should be able to develop 2D and 3D landmark detection and registration methods and have a working knowledge of various registration methods such as RANSAC and mutual information.
Title: GSP-based graph learning framework to estimate structural brain connectivity
Mentor: Gonzalo Mateos (Electrical and Computer Engineering)
In this project students will develop a GSP-based graph learning framework to estimate structural brain connectivity from functional signals measured by resting-state functional magnetic resonance imaging (fMRI). At the end of the 10-week research experience, students should be able to construct structural graph models of neural pathways in white matter and use statistical techniques to construct function graphs.
Title: Ultrasound stiffness imaging using deep learning
Mentor: Stephen McAleavey (Biomedical Engineering)
In this project, the student will investigate the feasibility of using deep-learning algorithms to obtain detailed images of tissue mechanical properties (e.g., viscoelasticity, anisotropy). Students will also study the correlation between mechanical property images and disease/injury. At the end of the 10-week research experience, students should be able to apply machine learning methods to train a network to estimate tissue mechanical properties from shear wave data.
Title: Big data imaging
Mentor: Justin Meeks (Neuroscience)
In this project students will analyze large imaging datasets obtained from LSM and 2-photon microscopes. Students will use these data sets to investigate neural networks and pathways that underlie mammalian social behavior. At the end of the 10-week research experience, students should know the theory and practice of producing, databasing, and analyzing large imaging datasets through LSM and 2-photon microscopy.
