Objective
I am a Ph.D. Candidate in Computer Science interested in solving current research
problems in electronic markets. I am most interested in modeling buyer and seller behavior,
better understanding auction dynamics, providing decision support for market
participants, or any similar challenges in online auctions or other strategic domains.

Experience
Google New York, NY
Software Engineering Intern: DoubleClick for Publishers, Summer 2012
Implemented dynamic programming, linear programming, and controller-based
methods of optimizing publisher revenue given Ad Exchange (AdX) bid distributions.
Created prediction and optimization testing frameworks for rapid prototyping and
evaluation of price predictors and optimization algorithms.
Visualized publisher data on various dimensions, such as impression competition
amongst a publisher s advertisers, expected revenue over the space of possible actions,
and revenue function approximations with respect to advertiser contract satisfaction.
Yahoo! Research New York, NY
Research Intern: Economics and Social Systems, Fall 2010
Implemented methods to infer advertiser values-per-click based on bidding behavior
across keywords.
Created hierarchical regression model to (1) understand which keyword features were
driving each advertiser s bids and values-per-click, and (2) predict advertiser
bids/values on new keywords.
Constructed models of advertiser click/cost beliefs from sponsored search logs.
The Search Agency East Greenwich, RI
Research Intern, 2009-2010
Developed methods to estimate sponsored search auction parameters using Google
bid simulator data from multiple accounts.
Created simulations to better understand counter-intuitive auction dynamics with
budget-constrained bidders, such as potential non-monotonicity in clicks with
increasing bids.
Brown University Providence, RI
Graduate Teaching Assistant, 2009-2011
Courses TAed: Autonomous Agents and Computational Market Design, Design of
Agents for Bidding in Sponsored Search Auctions, Introduction to Arti cial
Intelligence.
Co-led students in designing various components of autonomous sponsored search
bidding agents which ran in the Trading Agent Competition for Ad Auctions.
Led discussions on recent publications in sponsored search research.

Research Projects
Dutch Flower Auctions Rotterdam, The Netherlands
January 2011-present
Formulated MDP-based best-response algorithms to search for epsilon-equilibria in a
stylized model of the Dutch Flower Auctions.
Developed a simulator based on actual Dutch Flower Auction data to enable
evaluation of various price predictors and bidding strategies.
Trading Agent Competition for Ad Auctions Brown University
2008-present
Achieved 2nd place in the annual Trading Agent Competition for Ad Auctions in
2009, 2010, 2011, and 2012.
Developed demand predictors and multiple-choice knapsack-based optimization
algorithms for budget-constrained bidding in sponsored search.
Formulated mathematical programs to disaggregate average position data to more
accurately estimate the number of impressions seen by each advertiser in each slot.
Trading Agent Competition for Supply Chain Management Brown University, Univer-
sity of Minnesota
2004-2010
Reached nals of the annual Trading Agent Competition for Supply Chain
Management in 2005, 2006, 2008, 2009, and 2010.
Led Brown University s agent in 2008-2010, and team member for the University of
Minnesota s agent in 2004-2007.
Designed and implemented various supplier price predictors, sales price predictors,
procurement algorithms, and bidding algorithms using both mathematical
programming techniques and greedy marginal pro t-based algorithms.
Created a controlled testing framework to assist in game analysis, sensitivity analysis,
and variance reduction.
