Biomedical engineers are typically involved in research and design. They discover new knowledge that they apply to designing new engineering devices and systems for the fields of medicine and biology. Among the devices that biomedical engineering (BMED) has produced are noninvasive body imaging systems, critical-care monitoring instruments used in intensive care units, and a wide spectrum of implants, such as artificial joints, oral implants, and vascular grafts, all of which are used to replace diseased tissues. With new discoveries related to stem cells, genomics, and proteomics, BME is increasingly involved in cellular and molecular biology for basic research and design of new devices and technologies. Biomedical engineers are helping to advance the new field of tissue engineering. In this capacity, they use basic knowledge about the cellular/molecular processes of tissue regeneration to help design replacement tissues and organs. At Rensselaer, a key focus is functional tissue engineering, which encompasses the biology and engineering necessary to understand, characterize, synthesize, and shape the required mechanical and functional behavior of living tissues.
Founded upon a strong engineering base, the BMED curriculum combines significant life science content with courses that bring engineering solutions to medical needs. BMED students may select from a variety of concentrations to develop knowledge and skills in key areas of biomedical engineering including biomechanics, biomaterials, cell and tissue engineering, implant design, bioimaging, instrumentation, and computational analysis and modeling of biological systems.
Research Innovations and Initiatives
Biophotonics deals with the interaction between photons and biological matter. It offers great hope for early detection of diseases and for new modalities of light-guided and light-activated therapies. Continuing research includes (1) development of new imaging optical system for pre-clinical and clinical applications; (2) development of innovative computational methods for 3-D visualization and quantification of optical parameters in tissues.
Cell and Tissue Engineering
Mammalian cell cultures are used to study systems of biomedical interest at the cell and molecular level. Experimental projects in progress include (1) investigations of the mechanisms of osteoblast interactions with orthopedic/dental implant materials; (2) structure and biochemistry of the cell/biomaterial interface; (3) effects of mechanical stresses on cellular function, morphology, and structure; (4) the development of engineering tissues to repair or replace damaged tissues including the mechanistic understanding of neural injury and repair. Theoretical approaches are used in modeling proliferation of anchorage-dependent, contact-inhibited cells, and in quantifying morphological responses of cells to mechanical forces.
The level of complexity inherent in the study of human systems such as musculoskeletal or cardiovascular systems frequently dictates the need for numerical solution methods. Rensselaer is developing and applying high-performance computational methods to the study of diathrodial joint mechanics, cardiovascular mechanics, dental mechanics, and imaging. Projects involving the development of computational methods for bioengineering applications are done in collaboration with Rensselaer’s Scientific Computation Research Center, as well as the Center for Subsurface Sensing and Imaging Systems (CenSISS).
Ongoing research includes the design, packaging and integration of novel sensors into chronic implants to facilitate direct experimental measurement of physical parameters in vivo in (1) oral implants; (2) fracture fixation devices; and (3) spinal implants.
In an aging individual, musculoskeletal well-being is a key factor that contributes towards quality of life. Continuing research includes cellular and tissue-level approaches to (1) identifying changes in the biological and mechanical characteristics of skeletal tissues with emphasis on aging and osteoporosis; (2) developing microenvironments conducive to regeneration of lost or damaged bone matrix; (3) characterizing the mechanisms that cause degeneration of the intervertebral disc in response to loading; and (4) understanding the biomechanical effects of spine implants and tissue substitutes. Current research areas include biology and mechanics of hard tissue, cellular control of tissue growth and development, mechanobiology of skeletal tissue regeneration, fatigue fractures of long bones, mechanism of sclerosis of subchondral bone, and biomechanics of fracture fixation.
The Tissue Interface
In oral/maxillofacial surgery, orthopedic surgery, and tissue engineering, events at the bone-implant interface ultimately determine clinical implant performance. All such interfaces transmit loads, so interfacial biomechanics and biomaterials become extremely relevant. Continuing projects include (1) characterization of inplant biomechanics; and (2) assessment of bone biology at loaded verses unloaded bone-implant interfaces. New aspects of these projects include digital image-based strain analysis of interfaces and cellular/molecular-level approaches to understand interfacial bone healing and remodeling under the influence of interfacial biomechanics and biomaterials.

Objectives of the Undergraduate Curriculum in Biomedical Engineering
Graduates of the Department of Biomedical Engineering will:
- Be engaged in professional practice or be enrolled in high quality advanced academic or industrial training programs.
- Function in a technically competent manner to address challenges in biomedical engineering, medicine and biology.
- Contribute to and lead multidisciplinary teams in industrial, academic, and clinical environments.
- Be engaged in the design of biomedical products, processes, and systems within the context of ethical, societal, and environmental factors.
- Be engaged in life long learning that expands their knowledge and appreciation of global contemporary professional issues and practices.
Students may achieve these objectives through completion of the baccalaureate program leading to the B.S. degree. To ensure selection of the appropriate concentration and courses to meet individual interests and goals, students should consult their academic adviser as early as possible.
The department offers programs leading to M.S., D.Eng., and Ph.D. degrees. Persons seeking admission to any of these graduate degree programs in biomedical engineering should have their Graduate Record Examination (GRE) aptitude test scores sent to the Graduate Admissions Office. Applicants who cannot take the test should attach an explanation to the application. Submission of the GRE advanced test scores is also recommended. For further information on the GREs, write to Graduate Record Examinations, Box 955, Princeton, NJ 08541.
Matriculation into the doctoral program is based upon prior demonstration of a high level of academic achievement in graduate and/or undergraduate work. Advanced study and research are conducted under the guidance of a faculty member of the Department of Biomedical Engineering and an interdisciplinary committee. In order for a course to count towards the requirements, students must attain a B (grade) or higher.
A minimum of 30 credits in graduate course work (6000 level) are required in addition to the residency and thesis requirements. Students may need to take additional courses at the 4000 level to prepare for graduate level coursework. These requirements are formalized in a Plan of Study that is prepared in consultation with the student’s research adviser and doctoral committee.
The minimum course work requirements are distributed as follows:
Advanced Mathematics or Statistics 3-4 (1 course)
Advanced Life Sciences 6-8 (2 courses)
(Advanced Biology or Advanced Physiology)
Engineering depth courses 18 (5-6 courses)
(minimum of 3 courses should have the prefix BMED)
Advanced laboratory techniques 3-4 (1 course)
Courses directly related to all Biomedical Engineering curricula are described in the Course Description section of this catalog under the department codes BMED, CHME, ECSE, MTLE, and MANE.
Elective courses can be chosen from a recommended list of BME courses and other engineering and/or science courses at Rensselaer in consultation with the adviser.
For a detailed listing of approved courses in advanced mathematics, statistics, life sciences, laboratory techniques and engineering depth, see the BMED website at www.bme.rpi.edu.
