Nicholas J. Matiasz is a PhD student in the Department of Bioengineering and a lab member in both the Medical Imaging Informatics Group and Silva Lab. Nicholas is interested in the problems of causal discovery and experiment planning. He is developing a method to construct causal graphs from findings reported in the biological literature. In parallel, he is developing an approach to experiment planning that ranks potential experiments by their ability to inform an existing causal model. He plans to apply his work to improve the efficiency of scientific research and clinical practice. Nicholas is a developer for ResearchMaps (, a Node.js web application that allows scientists to track, integrate, and visualize causal information. His dissertation work is advised by Prof. William Hsu and Prof. Alcino J. Silva.

Nicholas received a Bachelor of Science in Electrical Engineering (BSEE) degree from Tufts University in 2010. His senior design project team developed a novel intonation method for electrolarynx devices, leading the university to apply for a patent on the design (publication number US20130294613 A1). As a graduate student at Tufts, Nicholas was a research assistant in both the Machine Learning Group (Dept. of Computer Science) and the Interpersonal Perception & Communication Lab (Dept. of Psychology), and received a Master of Science (MS) degree in electrical engineering in 2012. Before coming to UCLA, Nicholas was a research technician in the Department of Neurology Research at the MGH Institute for Neurodegenerative Disease.
