Hermenegildo Fabregat is currently a student at computer science Ph.D at the Deparment of "Lenguajes y Sistemas Informáticos (LSI)" at the National Distance Education University (UNED). He has been working as a researcher at LSI deparment at UNED since 2016.
In 2017, he obtained the MSc in Computer Science from the Complutense University of Madrid and in 2015, the degree in Computer Science from the Polytechnic University of Valencia.
His main research interest include Machine Learning and Text Mining applied to Biomedical datasets.

2017, Summer Sim Simulation and implementation of a low-cost platform to improve the quality of biological images.
The development of fluorescence microscopy techniques has helped advance in the understanding of molecular mechanisms present at biological systems, as the case of cell migration (Castillo-Lluva et al. 2010, Castillo-Lluva et al. 2013). These techniques allow studying the location, distribution as well as the movement of molecules that have been fluorescently tagged at a high resolution, even dealing with live cells (Rieckher 2017). In this paper a filtering and pattern recognition flow is simulated and implemented on a low-cost hardware platform in order to automate the detection of circular and ellipsoidal cells within the microscopic images. Results show that images keep a high quality after filtering and that 78.4% of the objects are properly recognized.

2015, PROLE Analysing the Termination of Term Rewriting Systems using Data Mining.
During the last decades, researchers in the field of Term Rewriting System (TRS) have devoted a lot of effort in order to develop techniques and methods able to demonstrate the termination property of a TRS. As a consequence, some of the proposed techniques have been implemented and several termination tools have been developed in order to automatize the termination proofs. From 2004, the annual Termination Competition is the forum in which research groups compare their tools trying to provide termination proofs of as many TRS as possible. This event generates a large amount of information (results obtained by the different tools, time spent on each proof, …) that is recorded in databases. In this paper, we propose an alternative approach to study the termination of TRS: to use data mining techniques that, based on the historical information collected in the competition, generate models to explore the termination of a TRS. The goal of our study is not to develop a termination tool but to show, for the first time, what machine learning techniques can offer to the analysis of TRS termination.
