My current research is focused on using Polarization Sensitive OFDI to image smooth muscle tissue in the lung, with the aim of gaining better understanding of the role airway smooth muscle plays in the development of asthma and the severity of asthmatic symptoms. To properly study this I ultimately intend to perform in vivo catheter based PS-OFDI imaging of airway dynamics. To assist with this I am also working on methods to extract accurate information about the optic axes of birefringent tissue, in both benchtop and catheter configurations.

Graduate Student/PhD program
I am a student in the Medical Engineering & Medical Physics program at HST. My research interests include the development and optimization of clinically-viable technologies for the early diagnosis and treatment of cancer. Current work focuses on refining OFDI-guided laser marking strategies for the guided biopsy of diseased tissue in the esophagus.

My research is focused on developing a method to measure blood flow in vivo using optical frequency domain imaging (OFDI). Being able to measure blood flow has wide applicability, especially in tumor vascular biology. We anticipate that our technique will allow a better understanding of how tumor vasculature changes as it develops, as well as how these pathological vessels respond to chemotherapeutic or anti-angiogenic therapy.

I am currently an MD/PhD student in the HST program. My research project aims to enable simultaneous intracoronary structural imaging and flow measurements to assess atherosclerotic plaques in patients. Specifically, I am interested in exploring emerging techniques such as polarization-sensitive OFDI and near-infrared spectroscopy for the characterization of vulnerable plaques.

Martin Villiger, PhD
The current focus of my research is catheter-based polarization sensitive OFDI. With novel reconstruction algorithms we attempt to compensate for polarization distortions that arise as light propagates through the catheter. This enables improved imaging of tissue birefringence and provides a complementary contrast mechanism especially for collagen. Imaging of collagen is of high relevance for intracoronary imaging as well as in a range of other endoscopic applications.
