BME Research Areas

To allow the student to concentrate in a specific area of biomedical engineering, we have partitioned the research programs of each of the faculty into generalized areas, representing pathways for the students to pursue. Importantly, the interdisciplinary nature of biomedical engineering means that these pathways are only meant to "guide" the student and in reality, it is up to the student to determine the nature of their research. Tying together molecular biomedical engineering with instrumentation may create a new biosensor based diagnostic or integrating biomechanics with biomaterials will ensure that structurally appropriate materials are used as tissue substitutes.

Again, the pathways are intended to help the student focus on a specific research area, but are, in no way, meant to constrain the interdisciplinary nature of the work. Indeed, the students are encouraged to "think outside the box," in terms of understanding the nature of human disease and developing new diagnostics, therapeutics or medical devices.

 

Biomaterials and Biomechanics

Biomaterials

Biom biomaterialsaterial combines both material sciences and biomedical aspects. A biomaterial replaces a part or a function of the body in a safe, reliable, economic and physiologically acceptable manner. A variety of devices and materials are used in the treatment of disease or injury. Common examples include sutures, needles, catheters, plates, implants, artificial skin, implantable devices and tooth fillings. A biomaterial is a synthetic material used to replace part of a living system or to function in intimate contact with living tissue. A biomaterial deals with the design, synthesis and applications of both living and non-living materials for temporary and permanent replacement of human tissues.

Biomechanics

Bio biomechmechanics implements broad knowledge of mechanical and civil engineering in solving biomedical problems. Biomechanics has a long history and has built a foundation for modern biomedical engineering. Mechanics is the engineering science that deals with studying, defining, and mathematically quantifying "interactions" that take place among "things" in our universe. Our ability to perceive the physical manifestation of such interactions is embedded in the concept of a force and the "things" that transmit forces among themselves are classified for purposed or analysis as being solid, fluid or some combination of the two. What alters mechanics into the field of biomechanics is the fact that biomechanics is the science that deals with the time and space response characteristics of biologic solids, fluids and viscoelastic materials to imposed systems of internal and external forces. The principles of biomechanics have been applied and used for monitoring physiologic function, processing the data thus accumulated, theories to explain the data, diagnosing why the human "engine" malfunctions as a result of disease, aging and ordinary wear, repairing and rehabilitating body parts and supporting ailing physiologic organs.

Bioimaging/Molecular Imaging

spectralThe field of Bio-imaging has experienced phenomenal growth within the last century. Whereas imaging was the prerogative of the defense and the space science communities in the past, with the advent of powerful, less-expensive computers, new and expanded imaging systems have found their way into the medical field. Systems range from those devoted to planar imaging using x-rays to technologies that are just emerging, such as virtual reality. Hardware design and software algorithm development for a wide array of imaging technologies applicable to medicine, including MRI, fMRI, PET and CT.

Tissue Engineering/Regenerative Medicine

Tissue engineering is an emerging interdisciplinary field which applies the principles of biology and engineering to the development of viable substitutes which restore, maintain, or improve the function of human tissues. This form of therapy differs from standard drug therapy in that the engineered tissue becomes integrated within the patient, affording a potentially permanent and specific cure of the disease state.

TEA large number of Americans suffer organ and tissue loss every year from accidents, birth defects, hereditary disorders, conditions and diseases. Improved understanding of biological processes holds promise for the development of new classes of biomaterials, polymers diagnostic and analytical reagents.

Tissue engineering integrates discoveries from biochemistry, cell and molecular biology, genetics, material science and biomedical engineering to produce innovative three dimensional composites having structure/function properties that can be used to either replace or correct damaged, missing or poorly functioning components in living systems. In addition, this emerging technology can be used to introduce better functioning components. The material components themselves may be processed from naturally occurring materials, processed from synthetic materials or a combination of these. Cellular and other biologic components may be added.

Tissue engineering faces the challenges in:

  • Permanent versus biodegradable
  • Optimal lifespan of scaffold or product
  • Degradation products
  • Biocompatibility
  • Optimal geometry/architecture/composition
  • Surface features (and how to modify them e.g., biomimetics)
  • Role of surface features in biointegration
  • Biomechanical characteristics
  • Reproducibility

 

Bionanotechnology

Bionanotechnology holds exciting opportunities to bring high-impact advances in the field of bioengineering and medicine. Exquisite biological nanostructures are a natural means by which cells interact with one another and with the extracellular matrix. Bionanotechnology offers at the nanoscale (100,000 times smaller than the diameter of the average human hair) the ability to provide insight into the structural features of biological systems such as cell or tissue as well as to develop nanobiomaterials/medical devices for diagnostics, therapeutics and tissue regeneration. Ongoing work includes development nanoprobes that can characterize the nanoscale structure and function of cells; design of multi-functional nanobiosystems for therapeutics, localized therapy delivery and for functional tissue repair/regeneration; innovative techniques for chromosome sorting; development of technologies to characterize the physio-chemical, structural and biological properties of nanostructured assemblies/materials; design of artificial biomaterials through molecular synthesis and nanoscale self-assembly.

Molecular Biomedical Engineering

cmbAnalysis and manipulation of the genome and development of processes for applying this knowledge in the clinic. Emphasis is on the discovery of novel genes active in tissue healing and adaptation as well as the development of therapeutic drugs, antibodies, vaccines, proteins and antisense products for agricultural, environmental and medical applications. Current work is being conducted on the progression of cardiovascular diseases, diseases of the musculoskeletal system. New technolgies, such as CRISPR, are being used for various applications.

Medical Instrumentation

MIToday's medical instruments are considerably more complicated and diverse, primarily because they incorporate electronic systems for sensing, transducing, manipulating, storing and displaying data or information. Medical diagnostic today more and more relies on detailed and accurate measurements of a vast number of physiologic parameters for diagnosing illnesses and prescribe complicated procedures for treating these. While medical instruments acquire and process information and data for monitoring patients and diagnosing illnesses, medical devices use electrical, mechanical, chemical or radiation energy for achieving a desired therapeutic purpose, maintaining physiologic functions or assisting a patient's healing process.

Development of novel clinical diagnostic, therapeutic and prosthetic devices based on advances in physiology research, materials, electronics and computational capabilities. Ongoing work includes use of vibromyography for diagnosis of osteoporosis, neural networks applied to heart auscultation, rapid sequencing of the human genome, self assembled materials, surface coatings to enhance tissue ingrowth and ultrasonic measurements of bone quality. The research topics include: Ultrasound - Diagnostic, Treatment, Biosensors.
