    Computer Vision in Breast Conserving Surgery

    Using stereo cameras and character based fiducials, we can aquire the surface of the breast in the operating room. This work-flow friendly data collection provides points to our image guidance system to enable continuous updates.

    Breast Deformation Correction

    Data suggest that nonrigid deformation will be an essential consideration in developing a novel image guidance system to compete with and outperform seed-based lesion localization methods. The previously uncharacterized shifts between supine magnetic resonance (MR) imaging and surgical position are likely crucial to breast image guidance and modeling approaches for highly accurate intraoperative tumor localization with supine MR.

    Image Guidance Platform

    Our image guidance system for breast conserving surgery provides a surgeon's tool tip in relation to all available patient data. Our system pairs conventional optical instrument tracking with novel computer vision surface measurements. Preoperative supine magnetic resonance imaging provides tumor position and extent.

    Machine Learning

    At the University of Central Florida, I worked on lung nodule classification using hand-crafted features and deep learning. At Tulane University, I developed a machine learning approach for detecting successful cell transfers for 3D bioprinting.

    About Me

    Outside of research, I am passionate about STEM education outreach, teaching, and supporting Women in STEM.

    Women of VISE

    I loved forming and leading WoV as a part of the planning team and the steering committee throughout graduate school.

    Glencliff High School STEM Outreach

    Throughout graduate school, I brought exciting science demos and lectures to students at Glencliff High School several times per semester.

    Center for Public Service at Tulane

    Through the Center for Public Service at Tulane, I served as a liason between students, community partners and faculty for service learning courses.

    Tulane Academic Learning & Tutoring Center

    The Tulane ALTC provides free tutoring and supplemental instruction. I am passionate about making additional instruction available and accessible to all. While at Tulane, I led the tutoring team and worked as a tutor.

    My Robo-Trainer

    In an effort to get fit for free, I built a little program in python to generate workouts and lead training sessions.
