Research
I'm a researcher at the division of Systems and Control in Professor Peter Stoica's group. I defended my PhD thesis, titled: Contributions to Signal Processing for MRI on May 8th, 2015.
My main field of research is signal processing, with the application Magnetic Resonance Imaging (MRI). By modeling the MR signal and estimating the model parameters from data, measures of tissue-specific physical properties can be obtained. The optimization problems solved are typically nonlinear, and require intelligent and application-specific algorithms to avoid suboptimal local minima. Designing such algorithms is a challenging research problem.
