  • Research

    I currently work on a couple of projects specifically at Beckman. With Mark Hasegawa-Johnson and his student Po-Sen Huang I collaborate on speech enhancement approaches that utilize deep learning. The goal of this work is to produce a system that can remove interference from speech recorded in noisy environments. This has resulted in a series of papers and also a conference award. With Art Kramer and his student Aki Nikolaidis I’m working on statistical analysis of brain data as
    collected from certain task experiments. This investigation is geared towards understanding plasticity and how various areas of the brain get utilized. We have one publication out of this work and Aki has also secured some funding on it (and will be a Beckman Institute Graduate Fellow in 2015-2016).
