Tim's aim is to use recently developed arbitrarily waveform generators to improve the current pulsed EPR experiments such as DEER, DQC, and SIFTER. He also aims to make potentially more effective experiments possible. The primary application of his work is to look at distances across proteins particularly for aggregating systems. He is trying to improve the study of distances on aggregating systems, especially on the model system of tau protein.
