  • PhD University of Nevada, Reno 2005
  • BSc (Hons) University of Newscastle upon Tyne 1999
Dr. Emma Hill is a geodesist specializing in using the geodetic observing system to measure natural hazards and climate change. She received her B.Sc. in Surveying and Mapping Science from the University of Newcastle-upon-Tyne, UK, where she studied the technical aspects of geodesy. Her Ph.D. in Geophysics was obtained from the University of Nevada, Reno, USA, where she used the Global Positioning System to study tectonic deformation in Nevada and California. During her time as a Postdoctoral Fellow at the Harvard-Smithsonian Center for Astrophysics, Dr. Hill used the global tide gauge network and an ocean general circulation model to study seasonal and long-term changes in sea level. Most recently, Dr. Hill was employed as a Geodesist (Research Scientist) at the Harvard-Smithsonian Center for Astrophysics, where she worked on a wide range of problems that included melting glaciers, sea-level rise, GRACE satellite gravity, and high-precision GPS. Dr. Hill is now employed as an Assistant Professor at the Earth Observatory of Singapore, where she will be using geodetic data to study natural hazards and climate change for the regions of South and Southeast Asia. Dr. Hill is a member of the Council of the American Geophysical Union, and Chair of the UNAVCO Education and Outreach Advisory Committee. Awards include the AGU Outstanding Student Presentation Award (2002) and a Zonta Amelia Earhart Fellowship (2001, 2002).
Research Interests
Research interests involve the application of space geodesy to understanding climate change and natural hazards, including measuring sea-level rise, tectonic deformation and melting glaciers using the Global Positioning System (GPS), GRACE gravity satellites and the global tide-gauge network. Future research will particularly focus on the regions of South and Southeast Asia. A particular focus is the development of techniques to combine different geodetic data sets for the purpose of separating the effects of the many different geophysical processes occurring in the Earth system.
Current Projects
  • Automatic Geodetic Processing
  • Monitoring sea-level change in SE Asia with the innovative use of GPS
  • Subsidence & Sea Level
