Current Projects | Disseminations

Research in the Biophotonics Laboratory at the Marquette University and Medical College of Wisconsin Department of Biomedical Engineering focuses on developing cost-effective optical solutions for use in cancer detection and treatment monitoring.  Recent innovations include the deep UV fluorescence microscope, the integrated fiber-optic probe for laser tumor ablation, and the Smartphone Microendoscope, a device that facilitates cost-effective and non-invasive detection and professional evaluation of cervical cancer for any organization with access to a smartphone. 


Current Projects


Breast tumor margin imagingDeep UV Scanning Microscopy for Breast-tumor-margin Imaging

The Biophotonics Laboratory is developing an intraoperative breast tumor margin imaging device with both large margin coverage and microscopic resolution that can accurately and efficiently evaluate an entire surgical specimen.
