Dr. Dunn’s Web site
Dr. Andrew K. Dunn earned his Ph.D. in biomedical engineering from The University of Texas at Austin. He joined the faculty of the College of Engineering in 2005.
Dr. Dunn develops advanced optical microscopy techniques used for imaging tissues, especially the brain. He seeks to integrate photonics and computational techniques to understand basic neurophysiological mechanisms and answer questions about strokes, migraines, functional mapping during neurosurgery and Alzheimer’s disease. Dunn is currently developing a system that would measure the brain’s blood flow, blood volume, hemoglobin oxygenation and oxygen metabolism during neurosurgery. The system could help physicians balance the tradeoff between removing malignant tissue and preserving brain function. Dunn also uses an imaging technique he developed, laser speckle contrast imaging, to study how blood flows through the brain during strokes, migraine headaches and normal brain activity.
