In this study, we investigate the effect of ENSO-driven hydro-climatic variability on the performance of Metro Manila water supply system. We focus on Angat reservoir scheme, a multipurpose system providing water to Manila and nearby irrigation districts, hydropower production, and flood control. First, we simulate the storage dynamics using the existing operating rules, historical inflow conditions, and user demands to study the correlation between various ENSO indices (e.g., Niño 3.4 SST Index) and system performance (e.g., volumetric reliability, vulnerability). Then, we use the most significant ENSO indices to generate multiple synthetic inflow sequences. The latter are used within a Multi-Objective Evolutionary Direct Policy Search (MOEDPS) algorithm to design reservoir operating policies conditioned not only on conventional information—such as storage, time-of-the-year, or current period inflow—but also on ENSO indices. Preliminary results show that this soft management solution reduces the system vulnerability during El Niño events.

I graduated in Environmental and Land Planning Engineering at Politecnico di Milano in 2007, and I received a Ph.D. in Information and Communication Technology from the same university in early 2011. Before joining SUTD as Assistant Professor, I spent two years as Post-Doctoral Research Fellow at the Singapore-Delft Water Alliance (National University of Singapore), where I led the Hydro-informatics group. I was visiting scholar at MIT (US), Deltares (NL) and University of Western Australia.

I am a member of the IFAC Technical Committee TC8.3 on Modelling and Control of Environmental Systems and of Environmental Modelling & Software editorial board. I also serve as Associate Editor for the Journal of Water Resources Planning and Management. I received the Environmental Modelling & Software 2011 Outstanding Reviewer Award and an Early Career Research Excellence Award (2014) by the international Environmental Modelling & Software society.

I actively collaborate with several universities and research institutes, including MIT (US), Politecnico di Milano (IT), TU Delft (NL), Deltares (NL), National University of Singapore, University of Western Australia and University of Adelaide.
