Profile Summary

Do you have some data to analyze/graph/report? No problem. As a data analyst with 15 years of experience, I have the technical knowledge and the communication skills needed to solve your problem and, most importantly, to give you a clear answer that you can apply to your field of interest. I offer a full data analysis stack, including: - Getting and organizing your data. - Selecting the most relevant statistical technique for your case. - Applying the technique to your data. - Assistance in applying the results to your specific field. I am equally comfortable working with corporate and academic clients. My projects range from a few hours of programming or consulting to ongoing client relationships spanning several years.
