Our lab uses optical imaging to investigate changes in the tumor microenvironment in response to treatment. Specifically, we are interested in studying the relationship between tumor oxygenation and metabolism, and its role in promoting undesirable tumor outcomes, such as treatment resistance, recurrence, and metastasis. The biomarkers derived from these investigations will lead to the development of optimized whole-tumor imaging methods that can identify patients who will benefit the most from treatment.

  1. BMEG 3124 - Biomedical Signals and Systems - This course introduces the basics of signals – continuous and digital signals, and signal processing tools, such as filters, Laplace and Fourier transforms. The ‘systems’ aspect of the course will focus on physiological systems and methods to model such systems. The course will also focus on the biomedical applications of these methods as part of a lab component.
  2. BMEG 4513/5513 - Biomedical Optics and Imaging - This course will provide students with a fundamental understanding of various biomedical imaging modalities. Topics will include the basics of light-tissue interaction and computational and analytical models of light propagation to quantify tissue optical properties. In addition, the course will also review clinical imaging modalities and recent advances in X-ray, Magnetic Resonance Imaging (MRI), Positron Emission Tomography (PET), Computed Tomography (CT), Ultrasound imaging, and Photoacoustic imaging.
