We are interested in the development of medical image reconstruction algorithms and their applications, and specific topics are as follows but not limited to:

• Photon counting detector-based computed tomography
• X-ray material decomposition
• Diffuse optical tomography
• Three-dimensional functional brain imaging using NIR light
• NIR light-based brain computer interactions
• Compressed sensing
