Research Interests

I am broadly interested in how plants on a cell-to-cell level process external information that affects their development. More specifically, I want to understand how this information in the form of abiotic stresses such as heat or drought is interpreted on a genomic level at various stages of development. My research primarily focuses on understanding how this information is stored and encoded in the context of chromatin and 3-dimensional contacts of DNA and its associated proteins inside the nucleus so that plants “learn” how to adapt to recurring stress situations. In my lab, we use next-generation sequencing, plant physiological, genetic, molecular and cell biology approaches to tackle these questions. Especially in light of climate change, it will be important to understand how plants react to changing environmental conditions.

Research Interests

Over the last decade phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2), a minor membrane phospholipid of the phosphoinositide family, has emerged as a key regulator of nerve cell activity. PI(4,5)P2 interaction with voltage-gated ion channels is essential for a large number of these channels. In addition, PI(4,5)P2 is critically involved in exo- and endocytosis, influencing neurotransmitter release and reuptake.A fundamental problem is how neurons accurately control PI(4,5)P2 levels, and quickly and reversibly adjust them to an altered physiological situation. However, despite the importance of phosphoinositides for the regulation of neuronal activity, little is known about how the metabolism of phosphoinositides is regulated in cells of the nervous system. To address this question, my research focuses on two major
areas:

  • Analysis of individual steps of phosphoinositide metabolism in a model system for hippocampal neurons by a combination of experimental and computational approaches. Development of mathematical models of phosphoinositide-dependent processes such as action potential firing of hippocampal neurons in response to simulated stimulation by neurotransmitters.
  • Analysis of second messenger signaling downstream of PI(4,5)P2 hydrolysis, specifically mediation of intracellular Ca2+-signaling by IP3 receptor-binding protein released with inositol 1,4,5-trisphosphate.

Research Interests

The Williams Lab tests the hypothesis that organisms, at various stages of their lives, are enabled through molecular changes to respond to alterations in their environment. Because molecular biology is a universally powerful tool to explore these questions, we have been able to ask questions in animals and plants as diverse as zebrafish, crabs, and sea grass. The majority of projects in the lab are, however, focused on how specific proteins (called transcription factors) work to coordinate normal development and respond to toxicants and oxidative stress agents. We study these proteins in a freshwater fish called the zebrafish.

Student Research Opportunities

Are you interested in how organisms grow? How about questions related to how chemicals can affect our health and well-being? In my lab using molecular, biochemical, imaging, and computational approaches, students can explore these questions working the zebrafish model. Please contact me if you have any interest in working in the lab.
