Edward Sun
Why did you decide to pursue a graduate degree?
In short, I enjoy being a student! I was looking for a way to continue my education while also taking ownership of my work. A thesis-based graduate degree seemed like the perfect way to pursue and expand on my interest in plant biodiversity.
Why did you decide to study at UBC?
I really enjoyed my time as an undergraduate student in UBC's Biology Program and decided that I wasn't ready to leave in my final year before graduating. UBC has one of the best botany departments in the world and I was eager to continue my research in the Graham lab.
What is it specifically, that your program offers, that attracted you?
UBC is such a diverse and inclusive school, which I value greatly. I was impressed by the quality (size, research output, opportunities) of our botany department and the range of research subjects its members are pursuing. Additionally, I was excited to keep working with my undergraduate thesis supervisor, who is always supportive and encouraging.
What was the best surprise about UBC or life in Vancouver?
UBC is a gorgeous school with so many places to explore. I'm a big fan of the botanical garden and the Beaty Biodiversity Museum. Also, I love this city for its recreational opportunities! There are so many well-organized running and cycling events, and I've met some great friends through being part of this community.
What aspect of your graduate program do you enjoy the most or are looking forward to with the greatest curiosity?
I love getting to travel to new places. During my graduate degree program, I've been able to travel all over British Columbia (and even internationally) to attend conferences and perform fieldwork.
What do you see as your biggest challenge(s) in your future career?
Research funding is always a concern! It can be difficult to find enough resources to support biodiversity research.
I am fortunate to have access to a wide variety of grant and fellowship application resources, including writing workshops and helpful faculty and staff members (who are willing to contribute their advice, even on short notice).
What aspects of your life or career before now have best prepared you for your UBC graduate program?
My experience as an undergraduate thesis student (Plant Biology Honours program) prepared me well for my program. It was the perfect training for my current work as a graduate student researcher. I'm also lucky to love what I'm studying, providing an endless source of motivation. Plants rock my world!
What do you like to do for fun or relaxation?
Anything outdoors (especially late-night dance sessions at the beach)! The running and biking scene is great in this city. I also like to indulge in a bit of amateur pottery and maintain a sizeable collection of orchids, which are my favorite plants.
What advice do you have for new graduate students?
Meet (and befriend) your fellow students. Graduate school is a great place to make friends who share your interests, values and beliefs.

Plant-fungal associations (e.g., through mycorrhizae) are widespread throughout the plant tree of life and have far-reaching implications for food and ecosystem productivity. Mycoheterotrophy is a unique ecological strategy in which plants parasitize their fungal partners to obtain nutrients, particularly fixed carbon, directly from fungi, and often indirectly from neighbouring green plants. Unlike typical plants that can photosynthesize and produce their own food, fully mycoheterotrophic plants have evolved to become entirely dependent on soil fungi for survival. They have forgone photosynthesis entirely and have lost many genetic systems that are otherwise common across green plants. The objective of my research is to study independent examples of this unusual plant nutritional mode across the land plant tree-of-life and to investigate genome-level changes accompanying the evolutionary transition to mycoheterotrophy.
Of the more than 50 independent transitions known across the plant kingdom, only a few cases have been studied with nuclear genomic data. I am sequencing, assembling and annotating the whole genome (i.e., the entire set of DNA instructions for a given organism) of fully mycoheterotrophic species from Burmanniaceae (in the yam order, Dioscoreales, monocots) and Gentianaceae (Gentianales, eudicots). Understanding the genetic changes that allow plants to live without photosynthesis will provide a broader perspective on plant evolution and alternative nutritional strategies. Studying their genomes can enhance our understanding of ecosystem dynamics, the interconnectedness of different plant species and plant-fungal relationships in general. The outcome of my research may therefore contribute to our understanding of general plant nutrition and is relevant to studying crop plants that form mycorrhizal associations.
