Every summer, we host undergraduates in the lab at the PVL and during the year we bring in volunteers to experience what professional research looks like. Today Ella, one of those undergrads, tells the story of their research journey so far!

Last summer, one of York’s monthly email updates featured an article on Dr. Haley Sapers’ expedition to Nunavut to test Mars rover simulations. The words, ‘astrobiology’ and ‘Mars’ immediately caught my attention. Seeing that Dr Sapers was part of the Planetary Volatiles Lab (PVL), I emailed Dr. Moores for potential opportunities to contribute to his lab. I exchanged an exciting conversation with Dr. John Moores and in the fall, I was assigned to help a PhD student, Grace Bischof, with her research on developing a Mars Microbial Survival (MMS) model. Fast forward, I completed eight months as an undergraduate volunteer at PVL and this summer, I received the NSERC USRA from NSERC and the Lassonde School of Engineering.
Now, what’s the actual science I’m working on, you may ask? The MMS Model estimates the bioburden reduction on Mars spacecraft during the cruise phase and on the surface. The MMS model calculates the quantity of terrestrial microorganisms remaining on a spacecraft's surface as it is exposed to the effects of the most deleterious space conditions. These include high vacuum, extreme temperatures, solar UV radiation, and ionizing radiation such as solar wind particles (SWPs). This is important because when we send spacecraft to celestial bodies like Mars, we want to prevent forward contamination as it can impact future exploration of extra-terrestrial life on Mars.
My enriching, fulfilling experience while doing research at the PVL, along with the challenges that came with it, has allowed me to grow both academically and professionally. The first challenge I faced was my limited background in space and planetary science. When I joined the PVL, I was entering my second year as a Biochemistry major and I barely knew anything about biochemistry, let alone planetary science. Although I still struggle with this knowledge gap, it has become easier to address by learning through literature searches. In addition, I also struggled significantly with programming. Grace’s project, the MMS Model, uses Python for calculations and graphing. While I had previous experience with HTML / CSS and Python through hackathons and self-learning, I had never worked with numerical modeling or data processing before. Familiarizing myself with these concepts was a challenge, and I essentially had to learn from scratch—from graphing to using various Python libraries for modeling. Google and Stack Overflow became my go-to resources. Fortunately, I am surrounded by passionate Mars experts with many years of research experience who are always willing to answer my questions.
Not only did I learn about all the exciting things about microbial survival, Mars, clouds, and the atmosphere, but I’ve also developed many technical and soft skills such as coding, writing, data collection, collaboration, problem-solving, and critical thinking, just to name a few. This invaluable knowledge and skill are something that I would have never formally gained from my degree alone. Engaging in research early on in my academic career has also allowed me to apply the knowledge I’ve learned in the classroom to real, practical research. My interactions with lab members have given me insight into the workload, the highs and lows, and the overall culture in academia, which has helped clarify my career goals and deepened my passion for planetary science and research.
Most importantly, I learned that research is not instantaneous – it is a journey composed of both productive and unproductive days. I learned that some days you might read 10 papers, write pages of words, and run many lines of code, while on other days, you might spend hours just sitting, thinking, writing then scratching and writing again. Although there have been times when I felt unmotivated, I still look forward to coming to the office every day with the same excitement I had when I first visited Dr. Moores’ office.
And of course, one of the best parts about doing research is the people! My interest in research comes from my aspiration to be part of a community that shares a profound passion for exploring the intricacies of the world and a dedication to immersing themselves in their questions – I found that community in the PVL. Some of my favourite memories are getting last place during bowling, dilly-dallying at Toronto Island, and eating lunch at the Petrie courtyard under the legendary Newton tree (manifesting a Nature paper!). I owe all of my positive research experience to my role models – Grace, Dr. Moores, and all the PVL members. Their support has been incredibly helpful in navigating my research challenges and has kept me curious about the world.
So, what’s next? Tomorrow, the next day, and throughout the rest of the school year, I’ll be heading to the Petrie building to continue my exciting planetary science research! Stay tuned ;)!
