Biomedical Kinesiology & Physiology doctoral student in the

Tell us a little about yourself, including what inspires you to learn and continue in your chosen field

I am a PhD student investigating whether the mechanisms of immunosuppression during isolation and confinement contribute to the physiological and kinesiophysical declines observed in astronauts upon return to Earth. Addressing this question may also yield important applications for health and recovery in terrestrial settings.

Why did you choose to come to SFU?

To join SFU鈥檚 Aerospace Physiology Laboratory and give me the opportunity to contribute to bioastronautical research.

How would you describe your research or your program to a family member?

In my research, I use a multi-omics approach to study how isolation and confinement stress may affect the immune system at a very detailed biological level. Here鈥檚 what that means: -Metabolomics looks at small molecules (metabolites) in the blood or saliva, such as hormones or byproducts of stress. These give us a snapshot of how the body is functioning in real time 鈥� like a biochemical 鈥渇uel gauge.鈥� -Proteomics studies proteins 鈥� the workhorses of cells 鈥� to see which ones are active or suppressed during stress. Proteins help regulate immunity, inflammation, and recovery processes. -Transcriptomics examines gene activity (RNA) to understand how cells are responding to stress signals. This helps us see which genes are turned 鈥渙n鈥� or 鈥渙ff鈥� in response to isolation. By combining these three layers of information, I can trace how stress moves through the body 鈥� from gene expression to protein function to the production of metabolites. This allows me to better understand whether these changes may contribute to immune weakening and physical decline after long periods of isolation, like in space travel. It also has real-world applications for understanding stress in remote environments, hospitals, or caregiving situations.

What three (3) keywords would you use to describe your research?

Integrative, Translational, Systems-based

How have your courses, RA-ships, TA-ships, or non-academic school experiences contributed to your academic and/or professional development?

I have been able to perform research into omics in an attempt to fill the research gap.

What have been the most valuable lessons you've learned along your graduate student journey (or in becoming a graduate student)?

It is not a straight path with many obstacles to be navigated. Some obstacles increase the stress of navigating the process. Cannot be faint of heart to endure.

How do you approach networking and building connections in and outside of your academic community?

I am dedicated to networking; your progress in the PhD; however, determines the level of networking achieved. You need to show through PhD candidacy or rigorous research design that your kab gas faith in you.

What are some tips for balancing your academic and personal life?

Always take care of your health; take time to exercise, be with loved ones, and enjoy life. Your journey is never straight unless you receive 100% guidance, so best to navigate in a way that retains health and vitality.

If you could dedicate your research to anyone (past, present and/or future), who would that be and why?

My late husband. He believed in me and my potential and I dedicated navigating life without him by contributing to humanity as much as possible.
