Sten Claessens

Dr. Sten Claessens is a Senior Lecturer at Curtin University's School of Earth and Planetary Sciences, within the Faculty of Science and Engineering. He holds a BSc and MSc in Geodesy from Delft University of Technology (Netherlands) and a PhD from Curtin University. His research focuses on gravity field modelling, geoid determination, and coordinate reference frames. He teaches courses on measurement adjustment analysis, control surveying, and applied geodetic surveying. Dr. Claessens has contributed extensively to global and regional geoid models, including the AUSGeoid2020 and Indian gravimetric geoid solutions. His work integrates satellite gravity data (GRACE, GOCE) and terrestrial observations to improve vertical datums and geodetic standards. He has authored/co-authored over 60 papers, with recent emphasis on hydrological loading studies and ultra-high-resolution gravity models. His ORCID profile (https://orcid.org/0000-0003-4935-6916) and Google Scholar page document his international collaborations and computational geodetic methodologies.

Education: BSc/MSc (Delft University), PhD (Curtin University). Professional roles include membership in the International Association of Geodesy and editorial contributions to Journal of Geodesy. He leads Curtin's geoid computation research, collaborating with agencies like Australia's National Geospatial Intelligence Agency on vertical datum modernization.

Research highlights include the Colorado geoid experiment (2020), development of layer-based gravity field models (2016), and Mars gravity validation studies (2012). Teaching responsibilities span advanced geodetic surveying units with practical field components.
