Working within Alexa, supporting data privacy via measuring the risk of exposing personal data within internal team datasets and machine learning models.

Part of the data science team within the Sponsored Products organization of the Amazon Advertising Platform. We work to build models like CTR, CVR, and Relevance to predict the performance of context-based advertising. I am currently working on Auto Targeting which leverages data and modeling to automate the identification of opportunities for Ads to show based on contextual information.

Worked on the Display Advertising Cornerstone team responsible for developing and maintaining the core advertising server for the Performance Display component of the Amazon Advertising Platform. I was involved in both CTR and Purchase model experimentation and helping to implement the current AdServer system.

Completed a PhD in CS in 2015 (while working full time.) Completed an MS in CS in 2008. My dissertation titled "Informed Search for Learning Causal Structure" delved into recasting causal learning, in this case the PC algorithm, as a Markov Decision Process and then developing a probabilistic policy to solve the problem. This policy was able to automatically identify Markov classes of causal models from an observational data set consistent with the PC algorithm. It did this by updating its prior over the causal model space into a posterior based on what it learned from applying causal inferences like marginal- and conditional-independence tests resulting in a marked reduction in the number of inferences needed to find the Markov class.My other research while in graduate school focused on knowledge discovery, relational learning, causal knowledge discovery, and collaborative peer-production systems. One interesting project I conducted was a social experiment involving nearly 100 individuals to study how people collaborate and compete in a photo sharing app.

Led teams of researchers for NASA contracts to help develop techniques for the V&V of adaptive software. Worked on a research team in the development of an intelligent flight control system.

Conducted research under Dr. Bojan Cukic on the V&V of neural network systems.
