Outreach Statement


As an earth scientist who studies past climate variability, I am very interested in and motivated by understanding anthropogenic climate change and working to increase public awareness of the serious changes happening on the planet. In order for the public to fully grasp the magnitude of modern warming, I believe it is critical to have some understanding of past natural climate changes. As such, I seek to share my research findings and knowledge outside of the scientific community as much as possible. I also am interested in working to increase participation in the sciences among groups that are currently underrepresented, particularly women. Below are some examples of my past and current outreach projects. 

  • I currently serve as president of CU's Women in Science and Engineering (WiSE) group, a community of graduate students and postdocs who seek to increase the retention and success of women in STEM fields through enriching seminars, professional mentorship, K-12 outreach, and community-building. I work with a committed leadership team of 25 women, and our monthly events reach hundreds of students and postdocs across the university. See my recent blog post on fieldwork in the Arctic.
  • I mentor undergraduate women in earth science fields through the Promoting Geoscience Research, Education, and Success (PROGRESS) program. 
  • As part of a seminar I took in fall 2014, I created a website summarizing the Intergovernmental Panel on Climate Change (IPCC) 5th Assessment Report (AR5) chapter on Paleoclimate. This website is designed to be understandable by the general public and highlights the most societally relevant aspects of the chapter.
  • In 2014 and 2015, I taught a field-based earth science summer camp for Boulder area middle school students through CU Science Discovery.
  • I have volunteered with local nonprofit Earth Explorers, sharing my science with middle school students from underrepresented groups in the sciences.
