Research Interests

Plants employ complex and intertwining signaling cascades, driven by chemical signals to translate and adapt to environmental changes. Local heterogeneities in water and nutrient availability, sudden changes in temperature, light or other stresses trigger and result in changes in growth. These developmental responses occur in a timely manner and involve swift changes in cellular protein abundance. Protein stability is a key element in the regulation of protein abundance, making the plant ubiquitin-proteasome system (UPS) regulatory function fundamental to plant response signals. We study the regulatory role of the UPS in plant signaling cascades and seek to uncover the molecular mechanisms that rapidly fine-tune protein abundance in plant cells in response to stress.
