Employment

I work as an University Lecturer at the University of Helsinki. I am also a principal investigator. I do research on sensory photobiology of plants, and other aspects of the role of acquisition and use of information by plants in acclimation.

I teach Plant Ecology.

Experience

I have been using TeX and LaTeX since around 1987, initially mostly for literate programming in Modula-2 with MWEB. At different times I have used different programming languages (BASIC, Pascal, Modula-2, C, C++, Java, Fortran, 6800 and 8086 assembler), scripting languages (awk, Perl, Ruby) and graphical programming systems (Stella, Simile, FlowStone).

I have been using R since around 1998, before that I used mainly Systat, but occasionally also S-Plus, SAS and MinTab.

I have developed software and hardware for use in different aspects of my lab's research in plant science.

I have earlier held a lecturer position in Environmental Statistics and taught courses on Satistics itself, and the use of R and SPSS.

Current work relevant to Stackoverflow

I am currently developing a suite of R packages for use in photobiological research, mainly for quantification of spectral data. Preliminary versions of some of these packages are described and available at r4photobiology blog and my Bitbucket public depositories.

I am also developing some instrumentation based on microcontroller boards like Arduino (see openinstruments blog).
