Fresh excitement for the Science Rendezvous festival
CSB shared our stories under shady trees as students, staff and faculty presented at Science Rendezvous 2025.
Science Rendezvous is an annual science festival across Canada, and we had many new faces from CSB to present our work on UofT's leafy Front Campus.
Squeezing in some neuroscience
Stephanie Shishis works on behavioural neuroscience in the Kim lab. Aided by volunteer Rubin Khandekar and electrodes from the BIOPAC system, they measured visitors' grip strength while showing the electrical pulses that were activating the grip muscles. This led to discussions of how these impulses can go awry in diseases like Parkinson’s.
Linking shape and function at the molecular level
Matea Maurice demonstrated all the forms that proteins can take and the variations that can change function, drawing on her research in the Saltzman lab. Visitors made their own alpha helices, beta sheets and intrinsically disordered regions out of pipecleaners and took these model proteins home.
Victoria Zhang and Neil Macpherson demonstrated the different organelles inside our cells, each of which has a fascinating function. From the shipping warehouse of the Golgi to the powerhouse of the Mitochondria, Zhang and Macpherson showed our guests the complexity of life, even within a single cell. They helped visitors understand the shape these organelles make through forming their own organelles out of modelling clay.
Karan Ishii from the Plotnikov lab cleverly demonstrated the physical forces that keep cells strong by showing how even a plastic bag that’s pierced all the way through won’t leak due to hydrostatic forces. She then explained to the large crowds gathered around her how she studies the forces exerted during cell migration and the cortical tension that keeps the cells intact.
It’s amazing what you can see with the right lenses
Plant scientists Professor Heather McFarlane and Yoshioka lab grad student Sofia Finley demonstrated the power of smartphone-compatible DIPLEscopes. With assistance from volunteer Abby Kuo, they revealed the columns, crescents and jigsaw pieces that cell walls make in different tissues of the plant; visitors took these beautiful patterns home on their phones!
Ernest Liang turned complex cellular patterns into a quiz. Guests were shown unlabelled microscopic images ranging from the folded leaves inside a seed to crawling cancer cells and were asked to guess which type of organisms they came from. The correct identification surprised many visitors, but some got it almost 100% right.
Our visitors were excited to look down the microscope and see tiny living organisms wriggling around on a plate. Ruby He and Linda Li of the Saltzman lab showed worms that move by rolling and going in spirals and contrasted these bioengineered worms with normal worms that move in a wiggly line. This activity was so popular, we had to cut off the line for visitors as our successful day came to an end.
Thank you to all our presenters, and to Lisa Matchett, Reta Aram, Tom Gludovacz and Alice DesRoches who helped with preparations!
Innovation, Excitement and Awards at CSB Research Day 2025
CSB Research Day 2025 on May 1st at University of Toronto Scarborough gave us a chance to share fun times with our colleagues, gain important insights into their research and celebrate their accomplishments.
Students, staff and faculty were welcomed by Professors Rene Harrison and Adam Mott and introduced to our venue, the impressive Sam Ibrahim Building. Our keynote speaker Prof Costin Antonescu of TMU revealed fascinating details from his work on receptor signaling at the nanoscale.

Gorgeous images win Nikon Small World Toronto competition
The winners of the Nikon Small World Toronto imaging competition have been announced!
We are proud that the top three winners as determined by imaging facility managers at SickKids Hospital were from Cell & Systems Biology! These images exploited the newest Nikon AXR NSPARC point-scanning confocal microscopy technology.
First place went to Damo Shi for “Immunofluorescence image of microtubules in the amnioserosa of fog-mutant Drosophila embryos”.
Second place went to Emily Deng for “From water to land: green algae transformed with an Arabidopsis protein required for chloroplast biogenesis”.
Third place went to Rebecca Tam for “Highly folded plasma membrane”.
You can see the full images in our gallery.
Shi’s research with Tirthankar Ray in the Harris lab showed that the amnioserosa of fruit fly embryos is confined by surrounding tissue to form a nematic, or crystal-like, structure.
Shi says that “My image for the competition submission was taken from an embryo with mutations of the gene fog, which perturbs confinement and causes reduced amnioserosa cell alignment.” Instead of aligning to outline crystal shapes, the red-stained microtubules in the fog mutant form stormy streaks.
Tam’s image shows a fluffy plasma membrane surface, contrasting with the usual image of the plasma membrane as a flat plane. This image comes from studies in early stage Drosophila embryos of how Arp2/3 proteins regulates cortical tension through patterning of myosin that is integrated with highly folded plasma membrane. In this image, the plasma membrane is coloured green and myosin is magenta.
Tam has shown how the plasma membrane is pulled by the centrosome to form a cap as fruit fly embryo cells divide, and this image shows the folding that occurs at a subsequent stage in the development of the Drosophila embryo. Tam recently won the Christine Hone-Buske award for her research.

Reid William James (Yoshioka lab) detailed their work "Investigating the Transcriptional Network within the Cyclic Nucleotide-Gated Channels (CNGCs) in Arabidopsis thaliana"
Vy-nhan Chanh Nguyen (Nambara lab) was recognized for "Unravelling the Regulatory Mechanism of ABA Catabolism Under High Humidity in Arabidopsis Thaliana"
Nicholas Garcia (Guttman lab) presented his work on unique transcriptomic responses evoked by PtoDC3000 Type 3 Secretion Effectors in Arabidopsis thaliana
Congratulations to these winners, and to all poster presenters for their hard work! Thank you to Melissa Casco and Genna Zunde for their hard work organizing the poster session.
Rising star in plant sciences Heather McFarlane awarded CSMB New Investigator Award
CSB Professor Heather McFarlane has earned the prestigious New Investigator Award from the Canadian Society for Molecular Biosciences (CSMB).
The CSMB grants this award to rising stars in cell and molecular biology and this award recognizes McFarlane's outstanding research on plant cell wall synthesis. Plant cell walls provide structure and flexibility to plants that allow them to form thin, flexible structures like corn stalks or trees.
Stress on plant cell walls, including stress from climate change, can reduce yields in important products like lumber, cotton and fuel crops. Previous attempts to modify plant cell walls for improved materials or biofuels have resulted in substantially reduced crop yields, showing that we don't fully understand how this economically important process occurs.
The goal of McFarlane’s award-winning research is therefore to study how plants sense and respond to cell wall changes to permit cell wall engineering that advances sustainability and yields innovative products. McFarlane and her trainees have already revealed important aspects of cell wall synthesis.
They have identified dozens of new molecular components of cell wall signaling and provided mechanistic insights into why some cell wall modifications are tolerated by plants while other changes can cause dramatic growth and developmental phenotypes. We look forward to further revolutionary work from this team.
McFarlane's excellence is reflected by her post as CRC Chair in Plant Cell Biology, by her Ontario Early Researcher Award and by her earning the Dorothy Shoichet Women Faculty in Science Award of Excellence.
Congratulations, Heather!
Congratulations to Professor Woodin on her appointment as President of University of Toronto
Professor Melanie Woodin, an internationally recognized neuroscientist at CSB, has been named the University of Toronto’s 17th president!
An accomplished leader, Woodin is current Dean of Arts & Science at U of T, president of the Canadian Association for Neuroscience and serves on the board of directors at the Vector Institute.
Woodin's Lab at CSB is focused on discovering the cellular mechanisms underlying inhibitory GABAergic synaptic plasticity in the healthy and diseased brain.
They employ a multi-disciplinary approach combining electrophysiology, biochemistry, fluorescence imaging, and behaviour to understand how synapses are built, the mechanisms that underlie their plasticity, and their role in neuronal circuits.
Woodin's studies unravel mechanisms that lead to neurological disorders and diseases, including autism spectrum disorder, Huntington’s disease and ALS.
“I am profoundly honoured to accept this appointment to lead an institution that I care about deeply,” says Woodin. “U of T is widely recognized as one of the world’s best universities and a highly trusted source for ideas, research, innovation and talent.”
Congratulations, Melanie!
Laptop or Lab? Research opportunity in Chang lab leads BCB student to embrace both
A Research Opportunity in the Chang lab led Alena Qin, a student in the Bioinformatics and Computational Biology program, to an appreciation for hands-on experimentation.
Students in Arts & Sciences can engage in research opportunities through the Research Opportunities Program. Qin was accepted into the lab of Professor Belinda Chang, whose lab works on recreating the evolution of visual proteins in the laboratory, using dry-lab computational methods, but also wet-lab mutational studies.
“The ROP has definitely helped me narrow the scope of the type of research I'm interested in,” say Qin. “I’m really enjoying the wet lab experience and I'm thinking of pursuing a career that’s more in line with that.”
You can read more about Qin's experience in "A&S Research Opportunities Program provides second-year undergrad Alena Qin with hands-on lab experience.
ROP courses are posted on CLNx in February when the applications start. You must apply on CLNx within the program application timeframe, which is from mid-February to mid-March every year, to be considered.
For other positions in Cell & Systems Biology, students can review the list of Faculty for labs researching their topics of interest and contact the professors. Not all professors have available positions in their labs, so it's good to contact several professors.
We are glad to offer these research positions to help students learn where their future can take them.
Excellence in Plant Science earns Professor Heather McFarlane the Dorothy Shoichet Award
Congratulations to CSB Professor Heather McFarlane on earning the Dorothy Shoichet Women Faculty in Science Award of Excellence.
