My research has focused on using biomechanical models to improve medical imaging. Neurosurgeons use MRI images as navigation tools during surgery. As the brain shifts during surgery, the images become inaccurate. Finite element models that capture the motion of the semi-porous brain matter can be used to correct these MRI images in almost-real time. Intraoperative 3D ultrasound images can supply sparse data to help improve this model-driven correction. My enthusiasm for teaching has recently attracted me to the research fields of physics and engineering education. I’m particularly interested in the topics of using educational technology effectively in the classroom, developing and using student assessments, teaching science through inquiry, and improving retention of underserved and underrepresented in science and engineering.
