Leonardo Alfonso Segura

Associate Professor of Hydroinformatics

Biography

Leonardo Alfonso is a Civil Engineer of the National University of Colombia, currently holding the position of Senior Lecturer in Hydroinformatics at IHE Delft. He has a combined consultancy and research experience in water modelling. He holds an MSc degree in Water Science and Engineering, specialisation Hydroinformatics at UNESCO-IHE Delft and a PhD degree from Delft University of Technology and UNESCO-IHE. Since November 2018, he has been acting as the Coordinator of the Hydroinformatics Specialisation, which is part of the Water Science and Engineering Master Programme and a component of the Erasmus Mundus Flood Risk Management programme.

Leonardo has several years of teaching experience that complements his practical experience in the field. He completed the University Teaching Qualification (TU Delft) in 2013, as well as a PhD Supervision course (Utrecht University) in 2017. To date, he has co-promoted 3 PhD students at TU-Delft, 1 at the University of Cassino (IT), and currently supervising 2 more jointly with the Sapienza University (IT), and supervised 25 MSc students on diverse water-related topics. His main teaching tasks include Information and Communication Technology, Real-time Control of Water Systems, Software for model integration, Matlab and Python.

He has participated in several capacity-building activities in Kenya, Rwanda and Myanmar and in Colombia, for which he is Country Coordinator and member of the Academic Research Partnership Colombia - The Netherlands.

He is member of the SENSE Research School, and member of the Sounding Board of the Orange Knowledge Programme of Nuffic.

Research Summary

Dr. Alfonso has participated in a number of European-funded research projects under the Seventh Framework Programme and H2020. Among others, he co-managed the FP7 KULTURisk project from 2011 to 2014, led the modelling work package of the FP7 WeSenseIt project (2012 - 2016) and managed various tasks in the Waternomics project (2014 - 2017). He is currently involved in the H2020 NAIADES project, where water modelling techniques are used to generate big data to feed an Artificial Intelligence platform to support efficient water management. Recently, he finished the H2020 Ground Truth 2.0 project, where he explores the value of citizen data with respect to monitoring networks.

His research interests are aligned with the three Hydroinformatics Chair research lines: 

Data, modelling, uncertainty and risk

  • Use of mobile and smartphone technologies for data collection (citizen observatories): complementing in-situ data with dynamic, intermittent, heterogeneous data coming from citizen observations.
  • Design and evaluation of (dynamic) monitoring networks.

Systems engineering, optimization and integration

  • Multi-objective model-based optimisation of water systems, including design and operation of urban water systems.

Collaborative decision making and Internet-based computing and learning

  • Decision making under uncertainty: incorporating decision-maker's beliefs in water-related risks decisions using Value of Information and Prospect Theory concepts.
