My goal is to use wearable technology for process audio and, specifically, speech data for data privacy preserving audio recording. In addition, I use audio and other sensor data to measure psychological variables and develop behavioral interventions in everyday life. If you can think across disciplines and want to apply computer science into practice, please reach out!
