Mission Statement

The Biomedical Engineering Department prepares students for rewarding careers in the health care industry or professional programs in biomedical research or medicine.

Educational Objectives

The educational objectives of the Biomedical Engineering Program, which embrace the WPI educational philosophy, are that our alumni 1) have successful careers, 2) apply sound science and engineering principles to impact the field of biomedical sciences in a socially and ethically responsible manner and, 3) will meet the changing needs of the profession through lifelong learning.

Student Outcomes

The Biomedical Engineering Program has established the following student outcomes in support of the educational objectives of our department. The general and specific program criteria meet the requirements for Biomedical Engineering accreditation by ABET (The Accreditation Board for Engineering and Technology). Accordingly, students graduating from the Biomedical Engineering Program will demonstrate:

  1. An ability to identify, formulate, and solve complex engineering problems at the interface of engineering and biology by applying principles of engineering, science, and mathematics
  2. An ability to apply engineering design to produce solutions that meet specified needs with consideration of public health, safety, and welfare, as well as global, cultural, social, environmental, and economic factors
  3. An ability to communicate effectively with a range of audiences
  4. An ability to recognize ethical and professional responsibilities in engineering situations and make informed judgments, which must consider the impact of engineering solutions in global, economic, environmental, and societal contexts
  5. An ability to function effectively on a team whose members together provide leadership, create a collaborative and inclusive environment, establish goals, plan tasks, and meet objectives
  6. An ability to develop and conduct appropriate experimentation, analyze and interpret data from living and non-living systems, and use engineering judgment to draw conclusions
  7. An ability to acquire and apply new knowledge as needed, using appropriate learning strategies
  8. An understanding of biology and physiology
  9. An ability to address the problems associated with the interaction between living and non-living materials and systems.

Biomedical engineering is the application of engineering principles to the solution of problems in biology and medicine for the enhancement of health care. Students choose this field in order:

  • to be of service to people;
  • to work with living systems; and
  • to apply advanced technology to solve complex ­problems of medicine.

Biomedical engineers may be called upon to design instruments and devices, to integrate knowledge from many sources in order to develop new procedures, or to pursue research in order to acquire knowledge needed to solve problems. The major culminates in a Major Qualifying Project, which requires that each student apply his or her engineering background to a suitable biomedical problem, generally in association with the University of Massachusetts Medical School, Tufts University School of Veterinary Medicine, one of the local hospitals, or a medical device company.

Each student’s program will be developed individually with an advisor to follow the Biomedical Engineering program chart. WPI requirements applicable to all students must also be met. See page 7.

Biomedical engineering is characterized by the following types of activity in the field:

  1. Uncovering new knowledge in areas of biological science and medical practice by applying engineering methods;
  2. Applying engineering principles to identify unmet needs in the medical and biological fields and implement high impact innovative solutions;
  3. Designing and developing patient-related instrumentation, biosensors, prostheses, biocompatible materials, and diagnostic and therapeutic devices; and bioengineered tissues and organs;
  4. Analyzing, designing, and implementing improved health-care delivery systems and apparatus in order to improve patient care and reduce health-care costs in contexts ranging from individual doctors’ offices to advanced clinical diagnostic and therapeutic centers.

The modeling of biological systems is an example of applying engineering analytical techniques to better understand the dynamic function of biological systems. The body has a complex feedback control system with multiple subsystems that interact with each other. The application of modeling, computer simulation, and control theory provides insights into the function of these bodily processes.

Recently, there has been increased emphasis on the application of the biomedical engineering principles embodied in the third and fourth areas listed above. Examples of the third area include:

  • designing and developing tissues and organs;
  • development of implantable biomaterials;
  • design of an implantable power source;
  • design of transducers to monitor the heart’s performance;
  • development of electronic circuitry to control the system;
  • bench and field testing of devices in animals;
  • application of new technology to rehabilitation engineering.

The fourth area involves closer contact with the patient and health-care delivery system. This area is commonly referred to as Clinical Engineering. The engineer in the clinical environment normally has responsibility for the medical instrumentation and equipment including:

  • writing procurement specifications in consultation with medical and hospital staff;
  • inspecting equipment for safe operation and conformance with specifications;
  • training medical personnel in proper use of equipment;
  • testing within hospital for electrical safety; and
  • adaptation of instrumentation to specific applications.

Biomedical engineering projects are available in WPI’s Goddard Hall and Higgins Laboratories, the Life Sciences and Bioengineering Center at Gateway Park as well as at the affiliated institutions previously listed.
