About

Ashley E. Fletcher is a leading researcher at the intersection of medical robotics and interventional imaging, with a primary focus on advancing robotic needle steering systems for minimally invasive procedures. Her most-cited work, "3-D Ultrasound-Guided Robotic Needle Steering in Biological Tissue" (2014, 98 citations), pioneered the integration of three-dimensional ultrasound as a real-time, low-cost guidance modality for robotic needles—a critical step toward making these systems clinically viable. Fletcher’s key contributions include developing novel methods for steering flexible needles through soft tissue while using 3-D ultrasound feedback to track and correct trajectories, addressing a major barrier in precision medicine. Her research has been instrumental in demonstrating that widely available imaging can replace costly alternatives like CT or MRI, potentially expanding access to robotic-assisted interventions. With her work cited by engineers and clinicians alike, Fletcher is recognized for bridging the gap between robotic control theory and practical medical applications, laying the groundwork for safer, more accurate tissue targeting in procedures such as biopsies and brachytherapy.
