UGA Engineeing Lecture Series: Christine Hendon

August 24, 2018 | 12:00 PM | Coverdell Center Auditorium (Room 175)

Christine P. Hendon, an associate professor in the Department of Electrical Engineering at Columbia University, will speak Aug. 24 as part of the UGA Engineering Lecture Series.

Translational Optical Imaging


The research goals of the Structure-Function Imaging Laboratory are to develop platform optical imaging systems to enable structure-function analysis of biological organ systems.  Towards this goal, we develop optical coherence tomography (OCT) and near infrared spectroscopy (NIRS) systems and automated processing tools to correlate tissue microstructure to electrical conduction and mechanical contraction. The main clinical drivers within our work are addressing unmet needs in cardiac electrophysiology, breast cancer and obstetrics. Within this talk, I will highlight our effort towards monitoring and guidance of radiofrequency ablation therapy with optical technologies. We propose to use optical imaging and spectroscopy as a means to monitor and guide radiofrequency ablation treatment of cardiac arrhythmias, which will directly interrogate the tissue for characterization in real time. There is typically an underlying substrate due to remodeling with the development of scar tissue or fibrosis that is the cause of the abnormalities in conduction patterns.  Therefore, better understanding how the microstructure of the myocardium influences electrical conduction will greatly inform these therapeutic procedures. I will present analysis of OCT and NIRS optical signals, metrics to extract information on energy delivery, remodeling and composition, and fiber orientations within human hearts. In addition, I will discuss our technical advances to enable real time monitoring of ablation therapy in vivo, including novel optical probes integrated within ablation catheters, extraction of polarization contrast to assess fibrosis, and the use of compressive sensing to reduce the burden of data and extract mechanical motion.


Hendon received the B.S. degree from Massachusetts Institute of Technology in Electrical Engineering and Computer Science in 2004, along with the M.S. and Ph.D. degrees from Case Western Reserve University in Biomedical Engineering in 2007 and 2010, respectively. She completed her postdoctoral fellowship at the Wellman Center for Photomedicine at Massachusetts General Hospital and Harvard Medical School in 2012. She joined Columbia University in 2012. She teaches courses on image processing and optical systems and leads the Structure Function Imaging Laboratory. Her work is currently funded by the National Science Foundation and the National Institute of Health, and she has received recognition for her work from Forbes' 30 under 30 in Science and Healthcare (2012), MIT Technology Review's 35 under 35 Innovators (2013), NIH New Innovator Award (2014), NSF CAREER Award (2015), and recently by President Obama, receiving a 2017 Presidential Early Career Award in Science and Engineering.
