Ana Laura Diedrichs
Ana Laura Diedrichs got her Information System Engineer degree in 2009 in Facultad Regional Mendoza, Universidad Tecnológica Nacional (FRM UTN), with 24 years old. During her studies, she applied for an DAAD-UTN scholarship and spent a semester (2008-2009) such as exchange student in the Technische Universität Carolo-Wilhelmina zu Braunschweig (Brunswick, Germany), taking part of the “WISEBED- Future Internet” project. Thank to this experience, she took contact with wireless sensor networks research. Back to FRM UTN, she took part of GridTICs research group, whose director is Ing. Gustavo Mercado, dealing with wireless sensor networks. In 2010 she and her coworkers received the 1st prize in the “Concurso de Proyectos Estudiantiles Simposio Argentino de Sistemas Embebidos” (Argentine Symposium of Embedded Systems) presenting the project “Método de Acceso de Bajo Consumo para IEEE 802.15.4” (low-power scheduling in IEEE 802.15.4). Since then, she has participated in several conferences in Argentina such as ARGENCON 2014, CASE 2013, SASE 2012, ENIDI 2009 giving talks about WSN topics. In addition, she has participated in the IJCAI school (International Joint Conference on Artificial Intelligence) on september 2014. Thanks to the UTN doctoral scholarship and the direction of her advisor Dr. Facundo Bromberg, she became a PhD student (2012-2016) at FRM UTN. Her research focuses on “Prediction of frost location using machine learning and wireless sensor networks”. The damage caused by the frost takes place when the temperatures are below than a tolerable limit for the plants. Each phenological state, e.g flowering, has a variable cold hardiness, so the lethal temperature is also variable. Freezing climatic events are the most dangerous, because they affect a large land surface. In order to study the micro-climate phenomenon of frost in Mendoza, Ana has been working with the GridTICs team designing a WSN, where sensors were distributed in the vineyards vertically as well horizontally; because the air temperatures change in both directions, and the plant has also different cold hardiness in the organs like trunk, flowers, shoots. On the other hand, for a better understanding of the phenomenon, she and Bromberg propose a study of the sensor relationships in order to improve the frost prediction. They are exploring the variables relationships using the independence approach by learning Markov Network structures from the environmental data. The analysis of the Markov blanket of particular sensors helps to identify which neighbor sensors could improve the prediction. The research is focused about the use of Markov networks as a supervised machine learning technique, for the feature selection purpose, and they are considering to improve other supervised learning techniques for inference. Another problem they are interested in is how to optimize the sensor locations in a field, in order to maximize the prediction power of the algorithms.
Interested in the following research topics: wireless sensor networks (WSN), context aware sensor networks, cognitive radio, machine learning, internet of things (IoT), multi-agent systems, reinforcement learning techniques, micro-climate prediction and behaviour.
Interested in the following technologies: contiki os, simulation tools, 802.15.4e TSCH,6tisch, issues for outdoor deployment of WSN.
