Welcome to Ruxandra Bondarescu's Page!
Welcome to my page. I received my PhD in physics in August 2008 from Cornell University and I am now a postdoc
at Penn State. I work with Sam Finn on recovering waveforms from LIGO data through a "maximum entropy"
method that cross-correlates data at different detectors. This is particularly useful for searches
in which we do not have a template for the gravitational wave signal. Additionaly, it is
faster than matched filtering and could also be used to narrow the search to templates
that are correlated with the data.

Teaching and TAing
These are two webpages with pics from boson star simulations. They were primarly written to convince my undergraduate advisor that we had enough for a paper and it worked :).
