Dear Colleagues, I am delighted to let you know that Leo Chiang has been selected as the recipient of the 2016 AIChE Herbert Epstein Award for Technical Programming for organizing the Big Data Topical during the Spring 2015 meeting. While I take credit merely for selecting Leo to organize this topical for CAST, Leo put in an extraordinary effort in conceiving and orchestrating all aspects of the topical. According to AIChE, ``the topical was the cornerstone “new draw” for the Spring 2015 meeting, was highly attended and attracted new Spring attendance from CAST, and others involved in IT/analytics/data analysis who had not recently participated in AIChE meetings.'' Please spread the word about CAST's Big Data Topical to any potentially interested parties. CAST continues this programming effort in 2016 and possibly beyond. Many thanks to Leo for his continued efforts in this regard. Best wishes, Nick Sahinidis CAST Programming Chair
