Calabia Aibar

Andrés Calabia is a recognized academic and an outstanding professional, specializing in geodesy, navigation, and remote sensing. He possesses a wide range of analytical skills, including data analysis and algorithm development. His research interests focus on data acquisition, the study and modeling of terrestrial environments through space geodesy and remote sensing, as well as the implications of these environments on human activity. His research aims to explore existing geodetic techniques to measure and interpret planetary variability, as well as to test, validate, and develop geophysical models. After obtaining his degree in Surveying and Geodesy Engineering from the Higher Polytechnic School of Building in Barcelona, Polytechnic University of Catalonia (UPC), Andrés Calabia worked as a field and office engineer on major public sector projects in Spain and the United Kingdom. Initially, he served as a surveyor engineer on large public civil engineering works in Catalonia, and later worked as a cartography and remote sensing engineer at the Department for Environment, Food and Rural Affairs in Reading, United Kingdom. After approximately 7 years in the industry, in 2013, Andrés Calabia received a full-time scholarship from the Chinese Scholarship Council (CSC) to pursue his Ph.D. in Astrometry and Celestial Mechanics at the Shanghai Astronomical Observatory (SHAO), University of Chinese Academy of Sciences (UCAS). Since the beginning of his Ph.D., Andrés Calabia has actively participated in numerous research projects led by his Ph.D. supervisor, the distinguished Professor Shuanggen Jin, establishing important friendships and academic collaborations in research and teaching projects that still endure today. The title of his doctoral thesis, defended in 2017, is “Thermospheric neutral density variations from LEO accelerometers and precise orbits,” for which he received the honorary award of “Excellent International Graduate of UCAS.” Subsequently, Dr. Calabia held a postdoctoral researcher position at the Colorado Center for Astrodynamics Research at the University of Colorado in Boulder, CO, United States, to continue his research on empirical modeling of neutral mass density variations related to the expansion of the upper atmosphere. Specifically, his research addresses how these variations affect the aerodynamic drag experienced by satellites. Precise tracking and positioning of satellites are essential for successful missions, and understanding the underlying physics is crucial. By quantifying the effects of changes in neutral mass density, the aim is to improve predictive models and enhance satellite performance. In 2018, Dr. Calabia assumed his first position as a professor at the School of Remote Sensing and Geomatics Engineering at Nanjing University of Information Science and Technology (NUIST) in Nanjing, China. For several years, he taught and led his first research project as principal investigator. Since 2023, Professor Calabia has held the position of professor in the Department of Physics and Mathematics at the University of Alcalá de Henares (UAH), in Spain.
