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.

Measuring Transient Cerebral Blood Flow Changes from Sensory Stimuli Using Transcranial Doppler

Ultrasound is a safe, noninvasive method of measuring blood flow in the body, and transcranial Doppler (TCD) is a special ultrasound mode that measures blood flow in cerebral arteries deep in the brain. TCD may be used as an inexpensive, portable method to measure brain response since neural activity is correlated with blood flow in the cerebrum. For example, a visual stimulus (such as a strobe light) can evoke a change in blood flow to the visual cortex. This can be seen by a relative decrease in the flow within the middle cerebral artery compared to the posterior cerebral artery. For clinical reporting, blood flow measurements are typically reduced to a pulsatile or resistive index. However, this index is typically based on long-term (i.e., tens of seconds) averages of data, and averaging removes the valuable real-time aspect of ultrasound.

Multicellular Biomimetic Liver Tissue Models Mimicking stages of Liver Fibrosis

Engineering in vitro models that reproduce tissue microenvironment and mimic functions and responses of tissues that is more physiologically relevant represents a potential bridge to cover the gap between animal models and clinical studies. In this project we will engineer in vitro models of liver tissues in an effort to understand the role of the tissue microenvironment (physical attributes, cell-cell communication, and ligand density) on the underlying biology of healthy and diseased tissues during progression of liver fibrosis. These platforms provide an ideal model to delineate the critical but unexplored role of liver microenvironment in the progression of liver disease and test new drugs to discover new treatment regime for the currently untreatable condition.

Nanoparticle-mediated sensitization of pediatric brain tumors to radiotherapy

Pediatric brain tumors contribute disproportionally to mortality in children because of the lack of available treatment options. Radiotherapy is one of the few effective adjuvant therapies available for these tumors after neurosurgical resection, but survival is frequently accompanied by radiation-induced lifelong developmental and learning disorders. As such, there is a significant need to reduce the amount of radiation required to achieve a curative effect. The goal of this project is to use brain tumor targeted nanoparticles to selectively sensitize pediatric brain cancer cells to radiotherapy.

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.

Disappearable Cyber Physical System Sensors and Actuators

The goal of this REU research proposal is to enable the next generation of wearable sensors and actuators: those that disappear within the natural orifices of the human body. Specifically, we will use the gastrointestinal (GI) tract as a location for a long-term biosensing and control application. Doing so will enable invisible, unobtrusive, long-term physiological monitoring to address the problem of infrequent, clinic-based measurements. The GI tract is an ideal location for miniature biosensing systems due to its large volume and surface area, proximity to vital organs and systems, and because it is a natural pathway into and out of the body. In pursuit of this goal, the research objectives are to solve the problem of long-term persistence of sensors and actuators within the GI tract which will require in vitro and in vivo testing and trials of new attachment designs, methods, and systems.

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.
