Soups Ranjan

Soups Ranjan is a seasoned data-scientist and software engineer with 10+ years of experience in two diverse areas: Ads (Local, Mobile and Social Media) and Cyber Security. He has applied his data science expertise with proven results in a variety of problems such as: Ad Click-Through Rate Prediction, Real-Time Bidding (RTB) Strategies, Click Fraud Detection, Social Media Spam Detection, Network Security, Anomaly Detection and Network Traffic Analysis. 

He has led teams of scientists and engineers towards building several successful products end-to-end from concept to development:
          • Yelp (2014 - ): CTR Prediction (Local Ads)
          • Flurry (2013-14): Ad Optimization and Mobile RTB Bidding Strategies (Mobile App Ads)
          • MyLikes (2011-13): Click-fraud detection systems, Twitter Spam detection (Social Media Ads)
          • Narus (Boeing Inc) (2005-11): Cyber Security product deployed at Tier-1 ISPs worldwide to detect DDoS attacks, Botnets, DNS poisoning, IP prefix hijacking, etc.
While at Narus Inc., he has managed multi-million dollar R&D projects granted to over 10 Machine Learning/Systems faculty at major US universities. He been awarded 15 patent applications by USPTO (detailed list at PatentMaps) and has published 25 high-impact IEEE/ACM papers with over 1000 citations, and an h-index of 17 (17 papers >= 17 citations).

He is a regular speaker at IEEE/ACM conferences, industry events and meet-ups on Data Science and Network Security.

He's passionate about how ambient location sensing can improve our lives, and has developed a popular expense reporting Android app called that ties your purchases to a location.

In his spare time, he enjoys digital photography and exploring Tilden park in Berkeley with his son and wife. He blogs occasionally covering complex technical, social and legal issues around cyber-security. He can be contacted at soups.ranjan AT gmail DOT com.
