Gordon Fitch

I’ve been fascinated by animals and plants for as long as I can remember, and it’s a dream to get paid to spend time with them and think about them. I’m motivated to better understand the intricate complexity of plant-animal interactions because I think this understanding is essential to conserving these interactions.

I became and ecologist thanks to the enthusiasm and passion of multiple mentors and role models, and I do my best to pay it forward by lighting the spark in others. I am dedicated to making the field of ecology more diverse, inclusive, and oriented towards justice.

Brandi Zenchyzen

I am an evolutionary developmental biologist passionate about exploring the remarkable diversity of floral traits and the ecological roles they play. I earned my PhD at the University of Alberta, where I integrated morphological analyses, chemical profiling, and transcriptomics to explore floral features tied to pollination biology—delving into the complexity of nectar colour, nectary structure, and floral scent. As a Postdoctoral Fellow in Dr. Fitch’s lab, I’m broadening my research beyond floral traits to include the dynamic interactions between plants and insects. My current research investigates how pollinators and herbivores interact with different chemotypes of Monarda fistulosa, each characterized by a distinct dominant monoterpene. Through field experiments, I aim to uncover whether these chemical differences influence insect interactions—a step toward linking plant chemistry with pollinator and herbivore behaviour.

Wildlife ranks top in my list of lifelong interests, to be able to spend the chunk of my life dedicated to “career” on it is something I am currently working towards. As my first project as a graduate student, currently I am expanding on the concept and potential effectiveness of roadside pollination sites as already established in the field of urban ecology. My lofty long-term ideals are: to become a researcher with a track record I can be proud of, and to help nudge urban systems throughout the world to be more considerate of ecological benefits in their landscapes and priorities without leaving anyone behind.

Ibrahim Ahmad

I am a first-year master’s student conducting research in the Fitch Lab. Im deeply interested in entomology, focusing on insect development, behaviour, and their interactions within ecosystems. In the lab, my research broadly focuses on bumblebee development and pollination behaviour, exploring how a change in environmental factors can shape their roles as key pollinators. Through this work, I aim to contribute to the understanding of bee resilience and preservation.

Shai Lis

As a Master’s student in the Fitch Lab, my primary research interest focuses on investigating the relationship between environmental stressors including disease, climate and insect herbivory and bumblebee foraging behavior, with a particular focus on flower choice in foraging bumblebees. In particular, my research will focus on understanding how environmental variables such as insect herbivory and soil quality impact plants, and foraging decisions made by bumblebees that pollinate them. I am also interested in understanding how the trypanosome gut parasite Crithidia bombi impacts foraging choice in bees. Coming from a background of undergraduate studies here at York University, I am truly passionate about uncovering the mysteries of these key pollinators, and how different stressors, including those caused by humans impact their behavior, and ultimately, their long-term survival. I hope that my research can contribute to the understanding, and ultimately conservation of these important pollinators.

Kajal Tabrizi Zadeh

As a third-year student in York University’s Biology program, my deep concern for animals and nature is one reason for my involvement in this research. I’m looking at how disease in bumble bees influences foraging on the plant Monarda fistulosa. This research explores whether bees practice self-medication, and will hopefully help us tackle the decline in the bee population. Through this experience, I’ve gained valuable practical skills and theoretical knowledge. I enjoy contributing to a cause that aims to support and protect bees, essential contributors to our ecosystem.

Fatemeh Shirshahi

I am currently in my fourth year of studying Honours B.Sc. in Biology, driven by a deep passion for science and medicine. My research focuses on the effects of the bumblebee digestive system on thymol, a naturally occurring nectar compound, to better understand its antiparasitic properties against Crithidia bombi. This work aims to contribute to pollinator conservation by investigating how thymol is processed, supporting efforts to reduce parasitic threats. I am eager to learn from my team members and gain valuable insights from them. 

Hananeh Kahlani

I’m a second-year biomedical science student at York University. I’ve always been deeply interested in biology, especially when it comes to plants and research. In the Fitch Lab, I have taken on tasks like processing and planting seeds and maintaining bumblebees. The project looks at how bumblebees interact with their environment and their fascinating ability to self-medicate. I love studying, exploring new materials, and constantly learning new things. My time in the Fitch Lab has been incredibly rewarding, teaching me valuable skills and deepening my passion for research.
