The algae with chlorophyll c are a major part of the marine biosphere. They include the diatoms, dinoflagellates, coccolithophorids, and many of the "nanoplankton"--very small microalgae that have recently been discovered to be an important part of the biota. All the algae absorb sunlight using chlorophyll-containing light-harvesting antennas, and use the energy to fix carbon dioxide in the process called photosynthesis. By removing carbon dioxide from the atmosphere, they contribute significantly to the regulation of global climate. In spite of this, they have not received much attention campared to their green plant relatives on land. This is now starting to change, with the sequencing of several important algal genomes. My research program integrates information from genomics, molecular biology and biochemistry to understand how these algal cells, particularly the diatoms, assemble their photosynthetic apparatus and how they adjust to changes in light intensity, nutrition and termperature in order to survive daily life in the ocean.

含有叶绿素c的藻类是海洋生物圈的主要组成部分。它们包括硅藻、甲藻、颗石藻和许多“纳米浮游生物”——最近被发现是生物群重要组成部分的非常小的微藻。所有藻类都使用含有叶绿素的光捕获天线吸收阳光，并在称为光合作用的过程中利用能量来固定二氧化碳。通过去除大气中的二氧化碳，它们为全球气候的调节做出了重大贡献。尽管如此，与陆地上的绿色植物亲戚相比，它们并没有受到太多关注。随着几种重要藻类基因组的测序，这种情况现在开始改变。我的研究项目整合了基因组学、分子生物学和生物化学的信息，以了解这些藻类细胞，特别是硅藻，如何组装其光合装置，以及它们如何适应光强度、营养和温度的变化，以便在海洋中生存。
