UW Catalog Description: Applies engineering analysis to understand human physiology and pathology of the engineering of solutions to medical and biological problems. Includes laboratory.
Instructor Overview: The purpose of this course and lab is to build a fundamental understanding of the biophysical and engineering principles that are the basis of cellular and systems human physiology. Discussion of disease processes and patho-physiology will be incorporated when appropriate. Recitation activities will teach and encourage design, critical thinking, quantitative analysis and an understanding of scientific methodology applied to physiological systems. An emphasis on communication skills will be reflected in recitation reports, group exercises and oral presentations. The recitation exercises complement the lecture material and emphasize the design of biophysical tools to underlying molecular mechanisms of human physiology and disease processes. The implications of various topics for medicine in general and the possible societal, economic or ethical consequences will be discussed.
Prerequisites by Course: BIOEN 215, 335, 336, 337, STAT 390 or IND E 315, BIOL 220.
Required or Elective: Required
Lectures: 80 min lectures; meets twice
Laboratory and Recitation: 3 hr laboratory/recitation, meets once per week
Computer Use: Students will use computers to prepare their homework, final papers, and class presentations
Laboratory/Recitation Projects: BIOEN 345 will have a laboratory or recitation component that will emphasize engineering and practical applications of the topics discussed in lecture.
Each physiological system module will be worth 150 points for a cumulative maximum of 450 points for the class. The grade distribution for each module will be determined by the lead professor for that module. The final grade is based on percentage of acquired course points.
Specific Outcomes: By the end of the course, students will be able to:
- Understand the physiologic processes based on the application of molecular and biophysical principles.
- Appreciate the complexity of interactions between various physical, chemical and physiological pathways that underlie both normal and patho-physiological states.
Outcomes Addressed by this Course:
C. An ability to design a system, component, or process to meet desired needs within realistic constraints.
- Design a microvessel system to mimic microvessel bed in different disease conditions (e.g. aneurysm, fibrosis, and atherosclerosis) considering the microvessel geometry, flow resistance and blood flow rates.
Course recitations will include multi-disciplinary team projects. Students will work together on case studies, and/or examine an assigned scientific article that describes a diagnostic or therapeutic, and/or work collaboratively on laboratory exercises and reports of these exercises. Students are responsible for critical analysis to assess the design criteria used to develop the new technology or therapeutic, and to evaluate and recommend alternative approaches. Student competency is assessed in presentations and discussions during recitations.
F. An understanding of professional and ethical responsibility.
- Identify the ethical implications of proposed solutions.
Students will analyze the impact of technology in diagnostic and therapeutic solutions in the context of healthcare access and cost, and other ethical implications. The reliability of sophisticated medical instruments will also be emphasized. Concepts and techniques are presented in lecture and practiced in problem sets and recitation. Student competency is assessed during laboratory/recitations, from problem sets and quizzes, and in the student presentations.
H. The broad education necessary to understand the impact of engineering solutions in a global and societal context.
- Evaluate diagnostic and therapeutic solutions.
Students will be required to apply what they’ve learned to evaluate diagnostic and therapeutic solutions in vascular, cancer or circulation biology. For example, students need to analyze new cancer detections or therapies considering cost, availability, and efficacy in the context of global health. Concepts and techniques are presented in lecture and practiced in homeworks and recitation. Student competency is assessed during laboratory/recitations, from problem sets and quizzes, and in the student presentations.
I. A recognition of the need for, and an ability to engage in, life-long learning.
- Apply self-directed inquiry to identify diagnostic or therapeutic solutions to failures in physiology.
Students will apply self-directed inquiry to identify diagnostic or therapeutic solutions to failures in physiology. For examples, students will be exposed to a timely need in cancer detection or therapy and will select a specific problem that they will address through a new technology. Concepts and techniques are presented in lecture and practiced in problem sets and laboratory/recitation. Student competency is assessed during laboratory/recitations, from problem sets and quizzes, and/or in the student presentations.
L. An understanding of biology and physiology.
- Learn about biological systems, such as the immune system, cardiac mechanics, and cancer biology.
Students will develop a sufficient understanding of the physiology and failure of cardiovascular, cancer, and immunological systems. Topics in vascular biology include flow, hemostasis, inflammation and atherosclerosis, cardiac mechanics and electrophysiology, and angiogenesis in tumors and retina. Cancer biology topics include tumorigenesis and tumor physiology, solid tumors, and maintenance of genomic integrity. Immunological systems and failures will include topics on immune cells and the effector mechanisms that orchestrate an immune response to pathogens, foreign body response related to transplantation, immunity in cancer, and diseases caused by immune responses. Concepts and techniques are presented in lecture and practiced in problem sets and laboratory/recitation. Student competency is assessed during laboratory/recitations, from problem sets and quizzes, and in the student presentations.
N. The ability to make measurements on and interpret data from living systems, addressing the problems associated with the interaction between living and nonliving materials and systems.
- Utilize diagnostic data to evaluate diagnostic and therapeutic solutions.
Students will utilize diagnostic data to evaluate diagnostic and therapeutic solutions. In particular, the utility and potential of these new approaches in cardiac, cancer, and vascular biology will be based on sample diagnostic data analyzed for cost/benefit ratio, sensitivity, accuracy, etc. The course recitation will examine recently developed tumor detection/monitoring approaches and immunological techniques that have been translated into diagnostic devices. Concepts and techniques are presented in lecture and practiced in problem sets and recitation. Student competency is assessed during recitations, from problem sets and quizzes, and in the student presentations.
Relationship of Course to Program Educational Objectives:
The purpose of this course is to build a fundamental understanding of the biophysical and engineering principles that are the basis of cellular and systems human physiology. A solid foundation in this key area of knowledge for the bioengineering field will help students progress towards future goals of advanced education or employment. Discussion of disease processes, patho-physiology, and medical tools and technology will further provide students with the terminology necessary to communicate across science and engineering disciplines. Recitation activities will teach and encourage design, critical thinking, quantitative analysis and an understanding of scientific methodology applied to physiological systems. These activities, coupled with the emphasis on communication skills, will help prepare students for professional advancement. The implications of various important topics for medicine and the possible societal, economic or ethical consequences will be discussed, providing students with a well-rounded education.
