Denis Alder - Services

I offer technical services in biostatistics and ecoinformatics, including the design of complex surveys and experiments, the analysis of data, simulation modelling of dynamic systems, and the development of software and information systems related to these. I work with several technologies including:

  • Web development: HTML, CSS, Javascript, PHP, MySQL
  • GIS: ArcGIS, QGIS, Python QGIS plug ins, Web mapping APIs
  • Statistical and data analysis: R, Excel/VBA, Systat, Statistica
  • Modelling and Application Development: Python, VBA, Java, Basic
  • Databases: MySQL, Access, SQL Server, heritage FoxPro systems
  • Mobile Data: ODK (survey data capture)

In the past, my main work has been with forest ecosystem modelling and agricultural surveys, land use change and carbon dynamics modelling. Since April 2017, I have been working with Valid International on the design and analysis of complex surveys for monitoring and evaluation relative to humanitarian relief, health and nutrition, and economic development.
