E-commerce fraud protection company Signifyd has recently signed up behavioral analytics expert Long-Ji Lin to fill the position of Chief Scientist.

“For advertisers, Lin perfected his model’s ability to predict which users would take each desired action, such as a clicking on an ad or purchasing from an advertiser. For e-commerce merchants, Lin is focused on innovations in modeling to verify if the user who made the purchase on their site is in fact the person authorized to do so, or if they are a fraudster,” the company explained.
