Hi, my name is Elioth, I’m a research scientist with a PhD in Operations Research from Columbia University IEOR Department. Currently, I’m working on multiple projects applying Operations Research to solve real world problems with state-of-the-art solutions. I founded Staffing Analytics, created the retail analytics plafform Predictheus and the data fusion platform EOS Intel.

Before this, I served in the NYC Government as Assistant Commissioner of Operations Research for the NYC Department of Correction solving a lot of logistical optimization problems (including supply chain problems, transportation optimization, staff scheduling and so on). I also served as Deputy Director of Operations Research for the Fire Department of New York City (FDNY), working on ambulance scheduling to minimize response times. This work was derived from my PhD thesis advised by Professors David D. Yao and Henry Lam.

While I have eclectic research interests, the common thread is a deep emphasis in technical correctness, practical applications and maximizing the positive impact for society by applying Operations Research.
