He later joined Healthline, an ontology backed medical search company, where he helped make multiple improvements to the product, including moving it from Lucene to a Solr backed custom engine, and introducing various improvements that combined advances in Solr with Natural Language Processing and Machine Learning technologies. At Elsevier, he has worked on large-scale search quality measurement, and is currently looking at image understanding and search.
