Research Interests Detail: 

The circadian clock is an emergent property controlling gene expression in organisms ranging from single-celled prokaryotes to the individual cells of higher eukaryotes like plants and humans. The clock aligns regular processes on the single-cell, tissue and organismal levels so that they occur in a time-dependent fashion with respect to each other and to daily oscillations in the natural environment (like daylight). I am broadly interested in elucidating the clock's inputs and outputs. Specifically, I am developing genetic (including transcriptional reporter assays) and metabolomic (including NMR, HPLC-NMR/MS) screens towards answering the following:

  • - How do cells in the same microenvironment synchronize their clocks?
  • - Can we isolate an intercellular chemical signal which explains this behavior?
  • - What are the metabolic/transcriptional pathways which produce and respond to this signal?
  • - What is its physiological relevance of local synchronization, and is it conserved in other systems?
