Tissue and Cell Biotherapeutics (TCB) Track

Note: This new track combines the Biomaterials and Tissue Engineering (BMTE) and Cellular and Molecular Biotechnology (CMBT) tracks together. Students currently in either BMTE or CMBT track may choose to switch to this track.


The TCB track addresses issues at the interface of materials science, biology and engineering. The topics include the interactions between materials and cells or tissues, the effects of such interactions on cells and tissues, the design of materials for biological applications, and the engineering of new tissues. It emphasizes fundamentals and applications of biochemistry, biophysics, cell biology, material science, and processes on the nanometer to centimeter size scale. Students in this track acquire an understanding of the molecular and cellular bases of life processes and build skills in quantitative modeling of live cell-based biotechnologies and in technologies that exploit the unique properties of biomolecules and materials in non-biological settings.


The TCB track is ideal for students interested in combining the education of Biomedical Engineering with Materials Science & Engineering or with Chemical Engineering. The track may also interest students in Mechanical Engineering and Environmental Engineering who have an interest in molecular aspects of Biomedical Engineering. It provides the necessary foundation in chemistry, molecular processing, and/or materials science. Students of this track may develop careers in biotechnology, tissue engineering, biopharmaceuticals, biosensors, drug delivery, and biological aspects of environmental engineering.

* The 42-x00 research project (42-200/300/400 Sophomore/Junior/Senior Biomedical Engineering Research Project OR 39-500 CIT Honors Research Project) must be on a BME topic that is aligned to the track, supervised or co-supervised by a BME faculty member, and conducted for 9 or more units of credit. 

Some Special Topics and newly offered or intermittently offered courses may be acceptable as track electives. Students should consult with their BME advisors and petition the BME Undergraduate Affairs Committee for permission to include such courses as track electives. The course petition form can be found here.
