I am a Sr. Applied Scientist in the Product Graph team at Amazon, Seattle, currently focusing on research and development of knowledge extraction techniques to build an authoritative, high quality knowledge base of products and product-related knowledge for Amazon and its customers.

Prior to joining Amazon, I graduated with a Ph.D. in Computer Science from the School of Informatics and Computing, Indiana University Bloomington (IUB). At IUB, my dissertation work, advised by Prof. Fil Menczer and Prof. Alessandro Flammini, focussed on design of computational methods for fact checking simple statements that can be expressed as (subject, predicate, object) by leveraging and mining large knowledge graphs such as DBpedia as background knowledge.

Broadly speaking, my interest lies in exploring applied problems that can benefit from techniques in Machine Learning, Natural Language Processing, Social Media Data Analysis, and Semantic Web technologies.

Before PhD, I was a Programmer Analyst at Transamerica Capital Management (TCM) in Cedar Rapids, IA, and an Application Developer at ITS-Enterprise Services in the University of Iowa. More information about my work experience or education can be found here.
