Margaret Jackson at Trinity College, Dublin

Dr. Margaret Jackson, our alumni, is starting a new position as an Assistant Professor at Trinity College, Dublin, Ireland! Dr. Jackson defended her PhD on February 25th of 2019, with Professor Meredith Kelly as her advisor. Her research focused on poorly understood tropical glacial fluctuations. Dr. Jackson showed that at low-latitudes, in East Africa and South America, glaciers reached their maximum between 29 to 20 thousand years ago, during the global Last Glacial Maximum and started their retreat by 20 thousand years ago, before the rapid CO2 increase that occurred 2 thousand years later. These findings provide a framework to understand connections between climate forcings, greenhouse gas concentrations, and glacial retreat at both high and low latitudes.
