I am working on a ecophysiological assessment of New York City’s green infrastructure. Focusing on bioswales, street-level rain gardens that collect gutter water, I am using transpiration and thermal infrared photography to evaluate the water use habits of different plant species. This will both provide input for a mechanistic understanding of diversity’s influence of community function and also give the city valuable information for optimizing the performance of future green installations.

I am broadly interested in exploring the consequence of various human interactions with the environment and the different scales at which they occur. Before entering the master’s program at E3B, I taught fishing and carpentry to New York City public school students. 


CURRENT PROJECT:  Career analysis

Some preliminary observations and statistical analysis on career trajectories.  Figure 1 is a JAC (Job Accumulation Curve) model, which is is typically asymptotic.  Fitting this model to x's career, x will likely have fewer additional new jobs for the remainder of x's life.  This [antecedent deliberately unclear], coupled with the data in Figure 2, suggest that, although x will likely be at a single job for many years, x will be increasingly unable to pay attention to that job, potentially resulting in overall ineffectiveness in one and increasing effectiveness in others, under the assumption of equilibrium, which can be relaxed, even if is not.  An interesting corollary is Figure 3, which establishes a negative linear relationship between x's ability to create graphs in R and x's ability to do anything else.  Notes:  Replication is low (n = 1).  Time is normalized to Sarah years which is constrained between 0 and 500.  Time is only plotted to 70 as instabilities arise for higher values.  The last figure represents analyses not part of this study, but clearly related.  Figure 4 combines these findings.
