Research Interests:

Magnetoencephalography (MEG) is a noninvasive brain imaging method with very high temporal resolution and good spatial resolution. Weaknesses of MEG include low signal-to-noise ratio and difficulty in the interpretation of complex patterns of signal. Many systems level responses remain difficult to interpret because of these weaknesses. My work includes efforts to interpret these responses where currently available tools have fallen short: there remain many questions in systems-level functional brain imaging that are easy to ask but difficult to answer. The result of the work is the development and use of approaches to recording and analysis of data that fall outside standard methods.

Current interests include long term learning, variability in brain response due to many factors, and improved characterization of responses to simple stimuli or multimodal stimuli.
