So excited to share a pre-print of my thesis work! Check it out to see how we can leverage an epigenetic resistance mechanism to PI3K inhibitors to target leukemic stem cells!! (Spoiler alert: PRC2 is involved!) Really proud of this work conducted with @gritsmanlab.bsky.social

So proud of Team Stemmy! Interdisciplinary collabs are the way to make a difference for preventing and curing cancer. @pmresearch-uhn.bsky.social @uwaterloo.ca
Three Waterloo grads — Isabella Di Biasio, Veronika Sustrova and Katarina Makivic — teamed up to automate blood stem cell analysis using ML and a custom scripting language. Their tool, developed with Princess Margaret Cancer Centre, aims to speed up cancer research.
