I am a Statistics Professor with research interests in spatial and temporal analysis of environmental data, including the development of risk assessment methods to evaluate the impacts of natural hazards under potential climate change. I did my PhD at Griffith University in Brisbane, Australia. I was a professor at the graduate programs of Statistics at Simón Bolívar University, Caracas, Venezuela for more than 20 years. I was a member of the Science Steering Committee of the Biospherical Aspects of the Hydrological Cycle project from the International Geosphere-Biosphere Program (IGBP) and Lead author of the Millenium Ecosystem Assessment report. I used to teach as a short term Visiting Scholar at the Department of Statistics at the University of California in Santa Cruz, between 2008 and 2017. I was a visiting professor at the Division of Statistics at Northern Illinois University during the academic years 2017-2019. I am now a visiting associate professor at the Department of Statistics at University of Illinois at Urbana-Champaign. I was elected as president of The International Environmetrics Society (TIES) for the period 2019-2021 and I am an Elected Member of the International Statistical Institute (ISI) since January 2019.
