Abedpour Lab
Computational Systems Biology of Cancer
Tumor cells live in a complex environment communicating with various non-cancerous cells including normal origin, immune, stromal, vascular, and many other cell types. Due to the stochastic genetic mutations and non-genetic modifications, tumor cells themselves also exhibit intratumoral heterogeneity that influences the tumor behaviour. Therefore, traditional bulk-level and single-omics profiling of the tumor is far from a realistic representation of the tumor characteristics.
State of the art single-cell multi-omics technologies can reveal cell biology with inimitable spatiotemporal resolution. However, appreciation of the value in this large amount of data requires advanced statistical methods that can capture the complexity at a systems level.
Our research focus:
The main focus in our lab is the study of tumor evolution (See the Figure 1). Unleashing the analytical capacity of multi-omics data at high spatiotemporal resolutions down to single cells level and at a systems scale is emphasised.
Our goals:
We aim in our lab to understand different aspects of cancer biology on a systems level. This includes malfunctioning of signalling networks, tumor evolution, stromal remodelling, immune system suppression, as well as the treatment response.
Our Approach:
We employ advanced statistical models such as Machine learning (ML), which are tools to automatically find patterns in data, to appreciate the complex biology of the cancer.
