Sanjika joined the Cognitive Computing group at eBay in September 2015 as a research scientist. His research focuses on machine translation (MT), natural language processing (NLP) and machine learning. Prior to joining eBay, he was a scientist at Raytheon BBN Technologies in Cambridge, MA for over 3 years, where he conducted research on error-tolerant speech-to-speech translation systems.

Sanjika received his MS and PhD from the Language Technologies Institute at Carnegie Mellon University in 2005 and 2012, respectively. At Carnegie Mellon, where he was a research assistant since 2003, his research focused on various aspects of statistical machine translation with an emphasis on low-resource scenarios, including the detection of translational equivalences in comparable data, MT system combination and domain adaptation. He has developed MT systems for major projects including GALE, BOLT and TRANSTAC, and for evaluations including NIST, IWSLT and WMT.

He has technical publications in major NLP conferences and journals including ACL, JMT, JNLE, and contributes as a reviewer for them.
