GENERAL INFORMATION:

Bioengineering is the integration of physical, chemical, or mathematical sciences and engineering principles in an engineering approach to problems in the life sciences. Bioengineering is a broad interdisciplinary field that brings together engineering, sciences (biology and chemistry, especially) and medicine to create new techniques, devices, and understanding of living systems to improve the quality of life. Bioengineering has major fields specialization tracks such as biomechanics, biomedical science and engineering, biomaterials (including cell and tissue engineering).

 

The roots of bioengineering goes back as early as 1950’s with groundbreaking developments in contact lenses, plasma expanders, pacemakers, ultrasound, artificial hip joints, etc. Bioengineering was approved as a graduate program in the USA and UK in 1947 and 1958, respectively. European Commission decided to support research projects in bioengineering area with a budget of 5 million Eurobetween the period of 1994-1998. The annual budget of USA Federal Government in 1993 for supporting such research programs was around 5 billion dollars excluding national supported projects and the industrial support.

Student interest, industrial, scientific and medical advances point to highlight a growing need for trained bioengineers all over the world. Employment opportunities for people trained in multidisciplinary areas such as bioengineering are increasing. People with special expertise in bioengineering will be one of the determinants for guiding the nations to achieve scientific excellence and improve their quality of life in the upcoming decades.

The primary goals of the minor program in Bioengineering are to provide the fundamentals of engineering and life sciences, teach the students to apply engineering approaches to biological problems and enable them to further specialize in special tracks of bioengineering, and broaden their perspectives. Today, many universities in the world have already established or are in the process of establishing undergraduate and graduate level bioengineering programs. This list includes four universities in Turkey, Hacettepe, Ege, Sabancı, and Başkent (see the attached Table). As the top technical Turkish University, METU,should also lead bioengineering education and research. To fulfill this expectation METU needs to establish a Bioengineering program of its own. Initiation of a Minor Degree in Bioengineering  might be a modest step in this direction. This program is being proposed as an undergraduate program intended primarily for Engineering and Science majors. Students participating in Bioengineering Minor Program (BMP) will have the training and excellent background to pursue further education in relevant graduate programs such as Biomechanics, Biomedical Engineering, Biotechnology, Medical Informatics and also will have strong preparation for a career in industry in rapidly developing areas of bioinformatics, biomechanics, biotechnology, biomedical materials and medical industry. Today, research towards problem solving rather than discipline-restricted researches are prevalent. Problem solving and communication are essential aspects of many jobs; an exposure to bioengineering topics will be helpful to most students by familiarizing them with the dominant theme in engineering which is solving problems involving multiple objectives.

The METU Experience: The potential interest among students from different disciplines towards Bioengineering has been tested by means of two courses offered by the Department of Engineering Sciences; ES 494 Introduction to Bioengineering and ES 704 Tissue Engineering within the last two semesters. Many graduate and undergraduate students have shown tremendous interest in these courses, in spite of very short notices. There were 34 registered students in ES 704, 16 of which are from Engineering majors, 18 from Sciences in Spring 2002. In Fall 2002, there are 21 registered students in ES 494, 17 of which are from Engineering majors, 4 from Sciences and 4 unregistered PhD students from Engineering. In  704, there are 17 registered students, 8 from Engineering, 9 from Sciences this semester. 

 

The Objectives of Minor Program in bioengineering are:

 

  1. To teach students principles of bioengineering and their applications in the life and medical sciences,
  2. To give necessary background to pursue education in related graduate programs (Biomechanics, Biotechnology, Medical Informatics, and Biomedical Engineering), To develop their ability to communicate effectively and participate in interdisciplinary teams including the medical doctors, too
  3. To expose students to a broad based education that prepares them for diverse careers,
  4. To develop skills to handle engineering tasks related with medicine and biology, 
  5. To provide students with a fundamental understanding of mathematics and the natural sciences, life sciences and medicine; an approach to problem solving which will serve the student well throughout their lives,
  6. To allow student to develop his/her interest in medical engineering applications while pursuing a traditional undergraduate engineering degree such as electrical, mechanical, chemical, etc.

 

MINOR PROGRAM IN BIOENGINEERING

 

The main objective is to teach student bioengineering principles and their applications in the life and medical sciences. Engineering students will receive necessary background to pursue education in related graduated programs: Biomechanics, Biotechnology, Bioinformatics, and Biomedical Engineering.
