Research interests

I am a post-doctoral research assistant in the Imaging Centre of Excellence (ICE) at the Queen Elizabeth University Hospital. I received my PhD in Biomedical Engineering and Master of Science degrees in Electrical Engineering and Biomedical Engineering from the University Michigan, and my undergraduate degree in Biomedical Engineering from the Illinois Institute of Technology in Chicago. More info about me is found on my personal site: https://sydneynw.github.io/ .

My research interests lie mostly in MRI physics, particularly RF pulse design. The ICE building is home to a CE-labeled 7 tesla ultra-high field scanner which offers the capacity for exceptional image resolution but also increased technical challenges that I am eager to help address. One example of a technical challenge for 7 tesla MRI is the inhomogeneity of the RF transmit field, which can affect image uniformity. The MRI physics team at ICE hope to combat this problem with parallel transmit (pTx) RF pulses, which offer a greater degree of freedom with RF excitation and the opportunity to correct inhomogeneities. My research for pTx pulse design involves mathematical optimization, MR simulations, and programming the MRI scanner. In the long term, I hope to incorporate pTx into 7 tesla scanning for clinical purposes, improving the diagnostic quality of imaging and healthcare of patients.
