I just returned from a fun event-filled couple days at Wright State Univeristy in Dayton, Ohio, visiting statistician Harry Khamis. Harry invited me to give two talks on Friday, November 2nd, 2012: one in Statistics and a second in Neuroscience, arranged by Thomas N. Hangartner. Harry was the model host; I always felt taken care of, my needs met.

We got one! Research Allocation Committee (RAC) Grants are for supporting new research or creative works. The RAC is particularly supportive of projects that may lead to outside funding and/or larger related projects.
Last year David Hanson and I began collaboration continuing his study in leaf respiration. I wrote a custom R package to process data from his tunable diode laser (TDL) and Licor devices to understand how carbon is taken up and respired by leaves. This summer a poster presenting some of what we’ve been learning was presented by graduate student, Dianne Pater, who has been designing and running experiments.
In a previous post I discussed this paper and how fun it was to write with Laurel. Here I’m happy to report it’s available electronically (SpringerLink, pdf) and soon in paper.
A few important areas of focus, reflecting what I’m doing and where I’m going.
