United States - Last active: 19 days ago - Tests: 5 - Portfolio: 1

I work with clients on defining, implementing and managing data analysis and data management projects. My expertise lies at the intersection of Statistics, Computer Science and Business acumen. Specific areas of interest to me are education, healthcare, finance, real estate, and energy. Analysis: R (statistics), Python (data munging), Java+Scala (machine learning / big data), VB.NET/Excel (financial modelling) ** Apache Hadoop, Hive, Spark with MLlib (big data ecosystem) ** MongoDB, Neo4j (NoSQL) + MySQL, Monetdb (SQL) ** Gephi (networks/social graph processing) ** Weka (machine learning) Visualization: Tableau (rapid dashboarding), Shiny (R package for interactive statistical dashboards) Environments: Linux, Windows, and Mac (least experience) Productivity: Git (source code control) Web Applications: Play 2 Framework (modern Java/Scala-based, reactive websites) I believe the key qualification to be a Data Science practitioner is an analytic and curious mindset. That said, many hiring decisions seem to hinge on specific skills. Let me know if there's a tool or technology you don't see on my list, and I'll let you know if I've worked with it before.

Germany - Last active: 23 hours ago - Tests: 8 - Portfolio: 1

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.
