Molecules are forever… and in their structural formulae, they record environmental conditions: temperature, precipitation, nutrient availability, pH. My lab's research focuses on how we can use molecules preserved in sedimentary archives - lake and ocean cores - to learn about past climate change. Why study past climate change (paleoclimate)? Just as history informs us about human behavior, paleoclimate informs us about the nature of climate change on Earth. In doing so, it also helps the climate community predict the effects of anthropogenic global warming. All this, from tiny bits of fat.


[2.9.15] It is with great excitement that I announce that I'll be joining the University of Arizona Geosciences Department as an Associate Professor in August of 2015! While I will miss WHOI, I am really looking forward to joining the vibrant group at UofA.

[2.13.15] The Ocean2K group has been working hard on our reconstructions of sea-surface temperature for the past 400 years, and our paper describing the results has just been accepted for publication at Paleoceanography. The reconstructions will be made available once the paper is posted on the journal's website.

Most annually resolved climate reconstructions of the Common Era are based on terrestrial data, making it a challenge to independently assess how recent climate changes have affected the oceans. Here, as part of the Past Global Changes (PAGES) Ocean2K project, we present four regionally calibrated and validated reconstructions of sea-surface temperatures in the tropics, based on fifty-seven published and publicly archived marine paleoclimate datasets derived exclusively from tropical coral archives.
