Bio: Ben joined the University of Melbourne in 2013 as a Senior Lecturer in Computing and Information Systems (a RAMAP appointee). Previously he gained four years of industry experience in the research divisions of Microsoft, Google, Intel and Yahoo! (all in the US); followed by a short stint at IBM Research Australia. As a full-time Researcher at Microsoft Research, Silicon Valley, Ben shipped production systems for entity resolution in Bing and the Xbox360 (driving huge success accounting for revenues in the $100m's); his research has helped identify and plug side-channel attacks against the popular Firefox browser, and deanonymise an unprecedented Australian Medicare data release, prompting introduction of the Re-identification Offence Bill 2016. He actively researches topics in machine learning, security & privacy, databases such as adversarial learning, differential privacy and record linkage respectively. His work has been recognised through an Australian Research Council DECRA award, and a Young Tall Poppy Science award. Ben earned the PhD in Computer Science from UC Berkeley under Peter Bartlett in 2010, collaborating closely with the SecML group, at the boundary of machine learning and security.

  • 10/2017: Invited speaker at the DARPA Safe ML workshop at the Simons Institute, Berkeley.
  • 7/2017: Open-source R diffpriv package released on CRAN based on ICML'2017 and AAAI'2017 papers. Provides many generic mechanisms for differential privacy, along with a sensitivity sampler that privatises arbitrary functions under random differential privacy, without the need to bound sensitivity or perform any math analysis whatsoever.
  • 7/2017: PhD student Maryam Fanaeepour wins the WiE Best Postgraduate Paper Award from the IEEE Australia Council for our ICDM'16 paper.
  • 3/2017: Open-source python OASIS package released based on VLDB'2017 paper to PyPI. Provides a principled, light-weight system for sampling examples to annotate for efficient (low budget) evaluation of highly class-imbalanced problems such as in record linkage. Implements this paper with Neil Marchant.

Teaching

I co-designed several exciting programs offered by my department (within Engineering): the Master of Business Analytics (joint with the Melbourne Business School), the Bachelor of Science major in Data Science and the Master of Data Science (both joint with Maths & Stats within Science). These programs reflect the interdisciplinary nature of machine learning and its allied areas.
