I am a PhD. candidate at the University of Koblenz-Landau and at the Data Science Group of the Computational Social Science department at GESIS - Leibniz Institute for the Social Sciences in Cologne, Germany. I am focused on analyzing (attributed) networks to understand and explain both edge formation, and biases in network inference. I work together with my supervisors Claudia Wagner and Markus Strohmaier, and colleagues Florian Lemmerich and Fariba Karimi (previously with Philipp Singer as well). 

During summer 2018, I did a second internship at the Information Science Institute (ISI) of the University of Southern California (USC). I worked together with Kristina LermanXin-Zeng Wu (Misha) and Buddhika Nettasinghe. Our project focused on the study of network biases in relational classification (e.g., network properties that could potentially affect classification such as assortativity, homophily, density, friendship paradox, majority illusion, etc.). In summer 2017, I was a 3-month Visiting Research Assistant at the Information Science Institute (ISI) of the University of Southern California (USC). I worked together with Kristina Lerman and Peter Fennell on analyzing the influence of sampling in relational classification. Previously, in January 2017 I was a 2-month Visiting Student Researcher at the Biomedical Informatics Research Department (BMIR) at Stanford. I worked on leveraging server logs (users actions through clicks and API requests) to model semantic foraging in BioPortal, a repository of biomedical ontologies. I worked together with Simon Walk and Mark Musen.

Master in CS: In 2014 I finished my Master's of Science (Computer Science) at 
University of Saarland in Saarbrücken, Germany, where I expanded my knowledge in Information Retrieval, Data mining and Databases. I joined the Max Planck Institute for Software Systems in 2013 to work on my Master's thesis where I leveraged
 user attributes and behaviors in order to discover topical context in conversations from Twitter. I worked together with my supervisor Krishna Gummadi and colleagues Juhi KulshresthaBilal Zafar and Saptarshi Gosh.

Engineering in CS: Previously, I got my Engineer's degree in Computer Science at 
Escuela Superior Politécnica del Litoral in Guayaquil, Ecuador where my major studies were focused on Software Engineering, Programming and Human-Computer Interaction. I joined Centro de Tecnologias de Informacion (CTI) as a developer and research assistant to work in several projects including my bachelor's thesis, an Online Social Network based on Liferay, under the supervision of Xavier Ochoa. During this time I also launched my own software development company neoBOX S.A., where I am currently the President and CTO.

Areas of expertise include: Online Social Network Analysis, Programming (Python), Web Development (HTML, PHP, AJAX, Javascript, CSS, ActionScript), Databases (PostgreSQL, MySQL)

Areas of interests: Graph Theory, Bayesian Inference, Social Computing, Urban Computing, Human Mobility, Big Data, Human-Computer Interaction, e-Government, e-Learning.
