Speaker: Dr Fabio Zanini (UNSW) Abstract: Single cell sequencing has recently opened a new frontier in biomedicine, enabling characterisation of cell identities and behaviours with granularity and scale. Most analyses take place at a mesoscopic scale of sorts: thousands of cells from a specific organ and organism (e.g. adult human blood) are individually sequenced and later computationally grouped (clustering, pseudotime) to gain biological insights. In this talk, I will tell two stories that challenge this paradigm in quite opposite ways. First, I will describe HyperSeq, a new experimental method combining microscopy and transcriptomics to find cellular diversity where there appears to be none: a healthy cell line. Second, I will outline atlas approximations, a desperate quest to fit all cellular diversity on Earth into a single online place. About the speaker: Fabio Zanini is a group leader at UNSW focussing on single cell biomedicine and open source software development. After a PhD at the Max Planck Institute (Germany) and a postdoc at Stanford University (USA), he moved to Australia in 2019 to create the Data Driven Biomedicine lab (https://fabilab.org). His research covers three areas: (i) Data science on specific biomedical systems including development of the lung, viral infections, immunology, and cancer, (ii) Bioinformatic software including HTSeq 2.0 and igraph, and (iii) Innovation in single cell methods including computational algorithms and experimental protocols. Fabio’s overall research passion is cellular diversity. This event will be held in person and online. Venue: Carslaw Building, Level 8, Access Grid Room Zoom: https://uni-sydney.zoom.us/j/84087321707
