Current Research

My research focuses on the area of biomedical imaging and its translation to clinical studies. Currently, I am carrying out research on the development of novel imaging techniques combining light and ultrasound, aiming to tackle the challenges of imaging inside the optical scattering biological tissue.
In particular, I am interested in the following research topics in this area:
  • Ultrasound modulated optical tomography
  • Time reversal deep tissue imaging based on optical phase conjugation
  • Photoacoustic imaging
  • Ultrasonic imaging with nonlinear ultrasound and contrast agents
  • Biomedical instrumentation and translation to clinical studies
