Desislava Petrova
Postdoctoral Fellow Climate, Air Pollution, Nature and Urban HealthDesislava Petrova is a co-chair of the Climate and Planetary Change Hub at ISGlobal. Her research focuses on climate dynamics, predictability and change. She holds a PhD degree in Climate Dynamics from the University of Barcelona, a research Master’s degree in Science of Natural Hazards from the University of Bristol in UK, and an undergraduate degree in Mathematics from Whittier College in California. Her main area of expertise is climate predictability at sub-seasonal to seasonal, inter-annual and decadal timescales, and particularly the predictability of El Niño Southern Oscillation (ENSO). During her PhD period, she developed a novel ENSO prediction model, specifically tailored to the long-lead predictions of this important climatic phenomenon.
Petrova is also interested in how climate forecasts can be incorporated within health and other impact models to increase their predictive lead time, and to develop useful climate services in help of vulnerable communities and decision-makers. She has participated in the development of prototypes of climate-driven early warning systems for dengue in Ecuador, as well as for temperature-related mortality on a pan-European scale. She has also been involved in research on climate teleconnections, variability and change, and specifically on quantifying and unraveling the dynamical sources of uncertainty of future rainfall projections in Mediterranean types of climates (especially in California and the Mediterranean region).
She is currently involved in a European project dedicated to climate and biodiversity tipping points (TipESM), and her work is concentrated on tipping scenarios for the Amazon rain-forest, including ENSO-driven changes in the region. She has a number of publications in high-impact journals on all of these topics.
