Imaging Sciences Pathway Courses

Fundamentals of Molecular Cell Biology (Biology 5068). The goal of the course is for incoming graduate students to learn about research on molecular mechanisms that underlie cell structure and function. As such, the course emphasizes research and experimental strategies. The course includes a strong emphasis on how the techniques and approaches of protein biochemistry are used in cell biology research. Topics covered in the course include protein structure analysis, protein purification, membrane structure and function, protein and vesicular trafficking, enzyme kinetics, receptor-ligand binding, membrane channel electrophysiology, signal transduction, the cell cycle, apoptosis, cell motility, and extracellular matrix. The format is two lectures and one small-group discussion section per week. Each discussion section focuses on one or more original research articles, which the students read, prepare written critiques, and discuss in the group, which is facilitated by a faculty member.

Molecular Cell Biology for Engineers (BME 530). This course is designed for students with a background in engineering. This course covers the biology of cells of higher organisms: protein structure and function; cellular membranes and organelles; cell growth and oncogenic transformation; cellular transport, receptors and cell signaling;the cytoskeleton, the extracellular matrix, and cell movement. Emphasis will be placed on examples relevant to biomedical engineering. In the discussion section, the emphasis will be on experimental techniques used in cell biology and the critical analysis for primary literature.

Principles and Applications of Biological Imaging (Biology 5146). The purpose of this course is to give students an overview of the field imaging sciences, providing them an introduction to the interdisciplinary nature of the field. This course is designed to briefly cover many interrelated topics that define biological imaging. Individual topics will be addressed with greater depth in classes later on in the students’ training.
Contrast Agents for Biological Imaging (Biology 5147; cross-listed with Chemistry 5147). This course is designed to build the chemistry foundations for how contrast agents are designed and utilized in diagnostic imaging. The chemistry of PET/SPECT, MRI, optical and ultrasound contrast agents will be covered. The chemistry of contrast agent design is diverse, and includes some working knowledge of organic, inorganic, physical and analytical chemistry methods.
Biological Imaging Technology (ESE 589; BME 494; 3 credits) This class will develop a fundamental understanding of the physics and mathematical methods that underlie biological imaging and critically examine case studies of seminal biological imaging technology literature. The physics section will examine how electromagnetic and acoustic waves interact with tissues and cells, how waves can be used to image the biological structure and function, image formation methods and diffraction limited imaging. The math section will examine image decomposition using basis functions (e.g. fourier transforms), synthesis of measurement data, image analysis for feature extraction, reduction of multi-dimensional imaging datasets, multivariate regression, and statistical image analysis. Original literature on electron, confocal and two photon microscopy, ultrasound, computed tomography, functional and structural magnetic resonance imaging and other emerging imaging technology will be critiqued.
Seminar in Imaging Sciences & Engineering (ESE 596/BME 506/Biology 5139).  This seminar course consists of a series of tutorial lectures on imaging science and engineering with emphasis on applications of imaging technology. Students are exposed to a variety of imaging applications that vary depending on the semester, but may include multispectral remote sensing, astronomical imaging, microscopic imaging, ultrasound imaging, and tomographic imaging. Guest lecturers will be from both Danforth and medical school campuses.  The only requirement is attendance at the lectures; the course is pass/fail. 
Dissertation Research The interdisciplinary training of the students in the Imaging Sciences program does not end with course work. Once the students are working with a primary mentor, they will be encouraged to continue interacting and carrying out experiments in the lab of faculty in other disciplines, primarily in the lab of the secondary mentor, to gain knowledge and learn techniques outside the expertise of their home laboratory. The culture of collaboration at Washington University will facilitate this objective.

Imaging Sciences Retreat

An annual Imaging Sciences retreat that the students assist in organizing is central to the cohesion and the definition of the Pathway. The main purposes of the retreat are to provide a forum to highlight current work by undergraduate and graduate students and to foster interactions among faculty mentors and students in the Pathway. The retreat is an excellent opportunity for students to learn about evolving and ongoing research opportunities, while providing an excellent means of exchanging new ideas and methodological information.
