About the Program

The Biomedical Engineering REU is designed to provide independent research experience for undergraduate students, broaden participant knowledge of opportunities in academia, industry and national laboratories, and introduce participants to interdisciplinary research in biomedical devices.

The goal of every medical practitioner is to improve quality of life for patients. Biomedical engineering and devices are instrumental in achieving this. The primary focus in each summer research project is biomedical devices designed to enhance medical care through science and engineering, with emphasis in two areas: (1) devices for diagnostics and sensing and (2) devices for therapeutics and intervention.

All projects are designed to be completed during the 10 week program and are a part of a faculty mentor's current research. This allows the student to be involved in many aspects of research, including design, analysis, simulation, and implementation of a biomedical device.

Students are also extensively involved in lab activities, such as weekly lab meetings. Research results are presented during lab meetings throughout the summer and at the end-of-summer in the Summer Research Symposium poster session. Lab members, especially graduate students and postdoctoral associates, are active with summer program research.

Design and development of a wearable ultrasound patch for measuring cerebral blood flow

Ultrasound is a safe, noninvasive method of measuring blood flow in the body. Transcranial Doppler ultrasound (TCD) is a specialized ultrasound modality that measures blood flow in cerebral arteries deep within the brain. TCD may be used as an inexpensive method to measure the brain’s response to stimuli since neural activity is correlated with blood flow in the cerebral cortex. However, methods to continuously monitor brain response are lacking. This REU project will create a wearable Doppler ultrasound device for real-time, continuous monitoring of blood flow velocity to measure brain response. The device will be constructed using soft, “skin-like” materials that closely match the mechanical properties of biological tissue to ensure conformal contact with the curved surface of the human body.

Engineering Nanomedicine for the Neurosciences

The field of nanomedicine offers the potential to improve the understanding and treatment of many disease processes by allowing researchers and clinicians the ability to deliver treatments to specific areas of the body, image where the treatments are going in real-time, and track responses. Therefore, the development of multifunctional nanoparticles has garnered significant attention especially for improving delivery into the brain for neurological diseases including traumatic brain injury, brain cancer, and dementia for which there is a significant lack of effective treatment options. These nanoparticles typically consist of a small core that acts as a scaffold to carry imaging agents for tracking nanoparticle localization in the body through various imaging modalities such as magnetic resonance and fluorescence imaging, therapeutic moieties for treatment, and targeting agents for binding cell surface receptors expressed in target tissue. The goal of the Kievit lab is to harness these capabilities of nanotechnology to provide strategies that will improve treatment of various neurological disorders.

Molecular Mechanosensors of Flow-induced Stem Cell Migration

Migrating mesenchymal stem cells (MSCs) contribute to homeostasis and modulate the repair of damaged tissues in vivo [15]. MSC migration-dependent regenerative medicine strategies such as cell therapies have, however, suffered from low efficiency in cell homing to the target tissue. While conventional soluble factor-driven static chemotaxis experiments have revealed some aspects of MSC migration and homing [16], there is a huge knowledge barrier with regard to how mechanical environments such as fluid flow-induced shear stress affect MSC migration [17]. Considering MSCs in vivo are exposed during migration to fluid flows in the blood vessel and interstitial space, this study investigates how physiologically relevant fluid shear conditions will affect MSC migration behavior.

Robotic Technology for Next-Generation Minimally Invasive Surgery

Robotic tools are becoming a standard fixture in medicine, and particularly in surgery, where they can help enhance dexterity and visualization in minimally invasive approaches. Inserted, in-vivo robots (like miniature surgeon arms inside the abdomen) can have particularly high functionality. However, the small electric motors that typically drive these surgical robots are problematic: they take up too much space for too little force and speed capability, and electrical connections multiply the possible failure modes and reduce reliability.

High Throughput Screening of Clinical Compounds that Prime Nonviral Gene Delivery in Human Mesenchymal Stem Cells

Human mesenchymal stem cells (hMSCs) are a multipotent cell type found in numerous tissues in the human body, such as bone marrow, fat, and muscle.  Due to hMSCs multipotency and ease of obtaining, they have become one of the most widely researched stem cell types in fields such as tissue engineering and regenerative medicine, and applications like targeted delivery of drugs/secretion of therapeutic proteins, and cancer therapy.  An area of high interest within these areas is genetic modification of hMSCs, which could be used to differentiate hMSCs, or to produce therapeutic proteins and signaling molecules.  However, potential clinical success of genetically modified hMSCs has been hindered by low efficiency of gene transfer to hMSCs via nonviral vectors.  While previous research has focused on modifying the delivery vector to increase transfection of hMSCs, the Pannier Lab is focused on identifying endogenous cellular factors, altered through chemical priming of clinically approved drugs that are important for successful nonviral gene delivery to hMSCs.

Fabrication of Microscale Hydrogel Beads Using Cross-flow-based Droplet Generation

Microscale hydrogel spheres have been widely used for biomedical research, such as cell encapsulation or three-dimensional cell culture. This project aims to fabricate such hydrogel beads using our cross-flow-based drop generator. In this effort, the water-based pre-polymer solution of a hydrogel will be injected through a syringe needle into mineral oil that rotates in rigid body motion. Then, monodisperse droplets of the solution will be generated at the needle tip by the motion of the oil, and the polymerization of the droplets will be controlled by either ultraviolet light or chemical cross-linkers.

Biomaterials and therapeutics to prevent low back pain

Low back pain is one source of orthopedic pain recognized as a widespread clinical problem resulting from degeneration and innervation of the intervertebral disc. Prevention of nerve growth into the intervertebral disc and reduction of painful stimuli has the potential to prevent disc-associated low back pain independent of disc degeneration.  Our lab develops natural biomaterial scaffolds to prevent undesired nerve growth and reduce nerve stimulation.  This project will work on developing and characterizing these natural material scaffolds and drug delivery devices to treat low back pain. Over the course of the first two weeks, the REU student will learn basic lab techniques such as how to isolate natural scaffolds, how to make decellularization chemicals, and how to decellularize tissue. During weeks three and four, the student will learn cell culture techniques and assays for analysis.  For the remainder of the summer, the student will culture various cell types including nucleus pulposus cells, macrophages, and/or stem cells in the decellularized tissue matrices to determine the effects of the matrix on cell phenotype and protein production.
