    I am a scientific researcher and freelance editor/proofreader with knowledge of physics, chemistry, astrophysics, biology and computing. I have a PhD in physical chemistry and a first class master's degree in physics and astrophysics.I have extensive experience in scientific and technical writing, with papers published in high impact, peer-reviewed journals such as Nature. I offer a comprehensive editing and proofreading service, which goes beyond just checking spelling and grammar. I specialise in preparing papers for journal submission and often work with authors whose first language is not English. As a published scientist, I understand journal requirements and what reviewers look for when assessing papers.  less

    I am a professional data scientist and statistical programmer operating under the guiding principle that much intelligence lies dormant and unrealized in today's data-intensive world. Over the last 17 years I have developed a highly-refined set of skills for handling large amounts of data and solving complex problems. My core competencies lie in analytical and statistical techniques including pattern-recognition, class discovery, predictive modeling, clustering and data visualization. I am always professional with excellence in communication, presentation and reporting. I have experience working with data in all of it's forms and the various challenges that arise. I'm comfortable working standalone or with remote servers and databases and can integrate statistical code/scripts into various systems, web dashboards, etc. I am a creative problem-solver, hard worker and native English speaker.

    I started as a physics teacher after my graduation from university but I always had in mind to become a scientist and if possible to combine that with teaching. Also, as I like biology it was always my goal as a scientist to apply physics to the study of biology. During my MSc and PhD research projects, both on plant physiology, I extented further my knowledge on plant sciences, namely plant physiology & biochemistry, plant anatomy and the experimental methods used in these disciplines. Over the last 6 years I have especialized on mathematical modelling of plant transport systems (membrane transport, phloem and xylem transport) for which I used Mathcad as my main tool for solving differential equations. Also, on the experimental level I have experience on isotope labelling, electrophysiology and the standard methods and equipment used in those fields.  less
