I am interested in developing data analysis techniques using the latest advances in statistical inference in order to leverage complex astronomical data. I work on probabilistic cataloging, a novel Bayesian technique that is able to handle extremely crowded stellar fields. The method is able to handle deblending ambiguities by treating the number of sources itself as a parameter to be inferred, using trans-dimensional Markov chain Monte Carlo sampling.
