Our BioMaths Colloquium Series resumes for the autumn term with a seminar by Dr Farzad Fathi Zadeh, from the Department of Mathematics at Swansea University.  Farzad is a Marie Curie - SER Cymru II Cofund Research Fellow in Mathematics at Swansea University & Guest Research Scientist at the Max Planck Institute for Biological Cybernetics (Germany). Farzad works on time series analysis and signal detection, including applications to multidimensional neurobiological measurements, multiple hypothesis testing in large datasets, and applications of stochastic analysis and geometric and differential analysis methods to a wide variety of practical cases.

I will talk about a novel and robust method based on making use of higher criticism for detecting signals and sorting peaks in electrophysiological measurements of neuronal activities, which are accompanied with considerable noise. The method relies solely on the intrinsic statistical properties of the data and avoids any preprocessing, which prevents the loss of any invaluable information. This is join work with E. Mitricheva, R. Kimura, N. K. Logothetis and
H. R. Noori.   

The discussions will continue over tea and coffee after the seminar. 
Hope to see many of you!
