Engineering light-based solutions for biomedical challenges.
We are focused on the development and translation of new tools for non-invasive characterization of physiology and disease. By working with multidisciplinary teams spanning engineering and medicine, our aim is to bring new technological solutions to the bedside, to address major challenges in medical care, and to improve patient outcomes and quality of life.
Raman scattering is an optical interaction that can be used for non-destructive physicochemical characterization of samples without the need for exogenous contrast or extensive sample preparation. We apply spontaneous and coherent Raman microscopy approaches to visualize and quantify spatial and compositional properties of biomedical samples.
Using portable system components and versatile designs for light delivery and collection, we develop devices that directly interface with patients in a clinical setting. Noninvasive tool development enables the measurement of pathological changes and treatment response to augment screening, diagnosis, monitoring, and prediction across multiple tissues and diseases.
Our lab is conducting groundbreaking research into pelvic organ prolapse (POP), a multifactorial condition that alters the composition of the extracellular matrix (ECM) and compromises the biomechanical integrity of the vagina. Currently, we are validating the use of a fiber optic Raman probe to assess the composition of the microstructure in healthy and afflicted patients with the goal of increasing treatment efficacy. Noninvasive technology that quantifies the biochemical makeup of the vaginal ECM is unprecedented and provides a unique opportunity to facilitate the understanding of POP etiology.
Data acquisition over time in 3D space with encoded spectral information provides rich, multidimensional signals for complex analysis. Spanning multivariate statistical modeling and machine learning techniques, we develop new analytical methods to extract and represent biomedical data for medical decision making.
High spatial and spectral resolution analysis, rapid measurements, and sensitive detection tools enable the characterization of disease markers. By looking at the heterogeneity of biomarkers in tissue and patient-derived samples, improved approaches can be created to quantify disease processes amid the natural variation of human physiology.
