Research Interests

Life displays complexity in many different layers; complex ecosystems emerge from simple organisms, complex organisms emerge from simple cells, complex cells emerge from simple molecules.

Often, our complex brains produce too simple a mind to grasp at the collective behavior of the parts making one of these layers. Computational modeling can make up for our shortcomings, allowing us to implement elementary rules to piece together pieces of the bigger puzzle. Led by this grand purpose, or maybe unfit for pipetting and lab coats, I joined the IT crowd of biology.

Over the past few years, I have been working on TGF-beta receptor trafficking in the context of liver fibrosis and regulation of gene expression by transcription factors. More recently, I have focused on gene expression patterning in the shoot apical meristem of plants, especially focusing on the CLAVATA-WUSCHEL feedback loop.
