My research focuses on the development of signal processing techniques for biomedical engineering systems, particularly with neuroscience and neuroengineering applications.

I lead the computational algorithms team at the multi-institutional BrainGate pilot clinical trial, which is investigating the feasibility of neural interfaces for motor function restoration in people with paralysis. My interest in the BrainGate project is in developing adaptive filtering approaches for multi-signal neural decoding to achieve neuroprosthetic control.

Another of our projects aims to develop point-process methods for identifying neuronal spikes from fast two-photon imaging data, enabling neuronal ensemble signal analysis for in vivo brain tissue. We also focus on time-series analysis and machine learning techniques for healthcare analytics.

Finally, I design wireless communications technology for a range of healthcare applications including chronically implantable stimulation and recording systems, telemedicine, 24-hour patient monitoring and wireless body area networks.
