Welcome to my primitive little home on the web. In addition to a bit of information about myself, here you can find:

• Selected publications that describe various projects I have worked on.
• Several algorithms, data-sets and other resources I have made available for download.

Current Gig

I am a Disinguished Software Engineer at Coinbase, working in the crypto-protocol team.

Research Interests

Currently I'm most interested in web3, digital & decentralized finance, blockchains, and trust-minimization in distributed computing. Previously I've worked in the areas of data mining, data science, applied machine learning, and web & enterprise search.

While I haven't been too active in authoring research papers recently, I remain active in the research community through participating in conferences in various capacities, including:

• The 2021 European Conference on Machine Learning and Principles and Practice of Knowledge Discovery in Databases (ECML/PKDD-2017), Senior Program Committee member.
• The 14th ACM International Web Search and Data Mining Conference (WSDM-2021), Program Committee member.
• 30th The Web Conference 2021 (WWW-2021), Web Mining and Content Analysis track, Program Committee member.
• IEEE ICDM 2021 21st IEEE International Conference on Data Mining (ICDM-2021), Program Committee member.
• 2021 IEEE International Conference on Big Data (IEEE-BigData-2021), Program Committee Member.
• 27th SIGKDD Conference on Knowledge Discovery and Data Mining (KDD-2021), Applied Data Science Track, Program Committee member.
