I got my BSc and MSc degrees in Biomedical Engineering, respectively majoring in Bioelectric and Radio-medical engineering, from Shiraz university in Iran. After a PhD in Applied Mathematics at the University of Manchester, I joined the Biomedical Ultrasound Group (BUG) at UCL. In the BUG group, I am working on ray-based methods for medical ultrasound computed tomography. Under supervision of Dr. Ben Cox, I developed a refraction-corrected ray-based method for full-3D ultrasound tomography of the breast.
During my PhD, I worked on the application of inverse problems, specifically iterative variational approaches, in Photoacoustic Tomography (PAT) and Quantitative Photoacoustic Tomography (QPAT). Under supervision of Dr. Sean Holman, I established an iterative framework for Photo-acoustic tomography of the brain using an adjoint-assisted inversion approach that accounts for absorption and dispersion. I also proposed a linearised inversion method for a single-stage simultaneous reconstruction of the optical parameters from the PAT time series. Using some realistic simulation studies, I showed that a linearised version of the single-stage problem of QPAT can significantly improve the image reconstruction, compared to the nonlinear gradient-based methods.
