Michael Jacob Pushie, University of Saskatchewan
Jake Pushie is a full-time staff scientist in the Department of Surgery at the University of Saskatchewan (Canada). My first visit to SSRL was in 2003. Autumn 2007 I became a regular user and over the past 15 years have had the pleasure of working and collaborating alongside some of the most amazing scientists and friends while visiting and collecting data at SSRL. My areas of interest are in the role of bio-metals in human health and disease, with particular focus on transition metal trafficking and coordination structure, as well as changes in trace elements associated with blood-brain barrier disruption and neurodegeneration. I have 66 peer reviewed publications, 35 of these have employed bio-spectroscopy beamlines at SSRL and 17 employed X-ray fluorescence microscopy beamlines at SSRL - and I feel like I’m only getting started! Much like the loss of wasted photons when we have beam, the loss of CPU cycles is also of concern to me as I use a broad range of computational chemistry tools at my home institution to help inform most of my synchrotron research. I was very impressed with how SSRL as a facility, and its staff, stepped-up and aided the user community during the pandemic. This only cemented my firm belief that SSRL is a facility like no other that researchers can rely on to enable the carrying-out of great science, no matter what. As a user I am also keenly aware of how difficult it is to train new users and grow the community. Such endeavours and outreach must start from within the user community itself and as a member of the UEC I envision opportunities to facilitate building user-led mentorships to educate, advise, and support new users - while also representing the needs and future interests of the existing user community.
