About Me

I joined Arizona State University in Fall 2013 as an Assistant Professor with a joint appointment in the School of Electrical Computer and Energy engineering and the department of Speech and Hearing Science. The overarching goal of research conducted in my lab is to develop and apply new machine learning and statistical signal processing tools to better understand and model signal perception. With a focus on speech, the goal is to develop reliable, data-driven models that can mimic aspects of human cognition. Some recent projects include developing non-parametric signal processing methods and using them to model pathological speech perception, developing auditory perception models based on psychoacoustics, and developing new machine learning tools for use with behavioral experiments.

Making progress against these goals requires an interdisciplinary approach that spans multiple fields. My contributions to this effort are centered on developing computational models guided by collected behavioral data. If you have any interest in these topics, please feel free to contact me!
