Data Scientist and Scientific Writer/Editor

I am a freelance data scientist with a strong background (and PhD) in biomedical research. My work relies heavily on data analysis, including examining large and often-messy data sets and utilizing techniques such as machine learning, building regression models, exploratory data analysis and the development of interactive apps and data visualizations. The majority of my analyses are performed in the statistical programming language R. I also have experience using Python and Octave/MatLab. Please see my portfolio for some of my more recent data science projects. I am looking for any projects that will give me more professional experience. At the moment, I am mostly interested in learning new fields within data science and data analytics and building up my portfolio. I am a native English speaker and have extensive experience in preparing scientific presentations and reports. I am available on short notice and keen to hear from you if you have a project that I could contribute to.

Experience

Postdoctoral Research Associate

University College London
May 2012 - Jun 2015 (3 years, 1 month)
I performed biomedical research on signalling pathways controlling tissue induction in early embryos.

Postdoctoral Research Associate

King's College London
Nov 2008 - Mar 2012 (3 years, 4 months)
I performed biomedical research into the gene regulatory networks controlling skeletal muscle formation. This work was based on a DNA microarray project, giving me hands-on experience in R programming and datasets on the order of 1 million observations.

PhD Student and Postdoctoral Fellow

Cancer Research UK London Research Institute
Jul 2003 - Oct 2008 (5 years, 3 months)
I performed biomedical research into the processes controlling blood vessel formation during embryonic development and in cancer.
