Carl Livadas

Carl Livadas is the Vice President of Data Science and Engineering at Sojern. Prior to Sojern, they were the Vice President of Optimization (RTB) at Nanigans from January 2014 to April 2017. In this role, they led the engineering and data science team responsible for building NanML, Nanigans' RTB machine learning pipeline and bid evaluation tier.

NanML included: 1) automated DAG-based ETLs to prepare the training data sets, 2) automated ML model training including feature generation, feature filtering, training, calibration, and evaluation steps, 3) hyper-parameter exploration on a per-model basis, 4) automated model deployment, and 5) a horizontally scalable bid evaluation tier to evaluate each RTB bid request on the behalf of each ad (post targeting matching). NanML supported rapid iteration by allowing Nanigans to explore new features, build new models, and experiment with new approaches to bidding within minutes, all without the need to deploy new code.

At the time, Nanigans was a leader among ecommerce, gaming, and other pure-play internet companies, enabling in-house teams to take control of their advertising through sophisticated workflow automation, predictive optimization, deep data integrations, and real-time and lifetime reporting tools.

Dr. Livadas received their PhD in Computer Science from the Massachusetts Institute of Technology. Prior to that, they received their MEng in Computer Science and MS in Aero/Astro from MIT. Carl also holds ScBs in Computer Science and Aero/Astro from MIT.
