Dr. Asa K. Rennermalm


Åsa Rennermalm is an associate professor at the Department of Geography at Rutgers, The State University of New Jersey. Her research interest is the hydrology of the Arctic region. Currently, she is discovering how water is transported and retained within the Greenland ice sheet to better understand how much meltwater escapes to the ocean and rising global sea levels. Her work involves modeling, satellite and in situ data analysis, and fieldwork. She has participated in several field expeditions to the Arctic, mainly Greenland.

Åsa joined Rutgers faculty in 2009. Before coming to Rutgers, she was a postdoctoral researcher at the Department of Geography at the University of California Los Angeles (advisor: Laurence C. Smith). Her Ph.D. is in Civil and Environmental Engineering at Princeton University (advisor: Eric F. Wood). Her master’s and undergraduate degrees are from the University of Copenhagen in Denmark (advisor: Henrik Soegaard).

Dissertation: Pan-Arctic Land Surface Hydrology: Patterns of Change and Global Implications. Advisor: E. F. Wood. Princeton University, 2008

Note:  Åsa [pronounced aw-suh] is a female first name in Sweden and Norway.

Awards & Distinctions

  • 2019: Kavli Fellow

    Kavli Frontiers of Science symposia bring together outstanding young scientists to discuss exciting advances and opportunities in a broad range of disciplines. The format encourages both one-on-one conversations and informal group discussions in which participants continue to communicate about insights gained from formal presentations and the excitement of learning about cutting-edge research in other fields. By doing so, Frontiers helps to remove communication barriers between fields and encourages collaborations.

  • 2019: Excellence in Teaching & Mentoring Award (Faculty) from the School of Graduate Studies

    The Excellence in Teaching and Mentoring Award recognizes graduate faculty who have made significant contributions to graduate education at Rutgers University. The Excellence in Teaching and Mentoring Award winner will receive a commemorative plaque at our annual Awards Ceremony.

  • 2018: First-Year Interest Group Seminars (FIGS) Mentors award

    We are committed to assisting students in making connections between their academic experience and career paths. We provide career-related resources to help individuals discover themselves, explore careers and academic pathways, develop skills, and pursue their post-graduate goals.
