About Me
My academic journey in solar-terrestrial physics began in 2007 at the University of Saskatchewan, following my graduation from the University of the Fraser Valley. After earning my MSc in 2010, I continued my research at Saskatchewan, ultimately receiving my PhD in 2015. I then moved to the University of Calgary to work with the Enhanced Polar Outflow Probe (e-POP) science team. Since joining NJIT in 2019, I have had the privilege of collaborating daily with world-class scientists and exceptionally bright students.

Research Interests
For nearly 15 years, I have had the distinct pleasure of investigating the most compelling problems in solar-terrestrial physics. My research focuses on plasma structuring and dynamics within the terrestrial ionosphere and magnetosphere. Utilizing both in situ and remote sensing observational techniques, I study the complex, interconnected processes of Earth’s geospace environment, with a particular emphasis on high-latitude regions.
I find this work incredibly rewarding; it is both intellectually challenging and provides the opportunity to collaborate with brilliant colleagues at the New Jersey Institute of Technology (NJIT) and across the globe.
