Welcome to my personal academic website

I am Lecturer in Networks and Security at the School of IT at the University of Sydney. I also lead the Node for Cybersecurity and Usable Security inside the Human-Centred Technologies cluster.

One of my goals is to make the Sydney area a great place to do R&D in IT Security. To this end, I am also Contributed Staff to Data61|CSIRO, a Visiting Fellow at the University of New South Wales, and a member of the Sydney Cybersecurity Network.

Research Interests

My research interests revolve around security and (network) measurement, with a decidedly empirical approach. My current interests are:

  • Global-scale measurement of Internet service deployments and their security
  • Data-driven security mechanisms
  • Analysis of blockchain technology and its implications

My theme is real-world security: security is achieved only by technology that supports its human users. No matter how brilliant the technology, if humans find it hard to operate, it will be insecure. Similarly, technology is always used in a context (at home, in finance, etc.) and this context is important in understanding how a technology must designed.

Bio

I hold a PhD from Technical University of Munich. I did both my post-grad and under-grad studies at Eberhard Karls University, Tuebingen, one of Germany’s classic universities.

I also am a Visiting Lecturer at the University of New South Wales and a Visiting Academic at Technical University of Munich. As contributed university staff, I frequently collaborate with Data61 (CSIRO), Australia’s premier innovation group.

Prospective Honours/SSP/Capstone/Internships

I welcome new students for projects in S1 or S2 of 2018. I offer a range of topics in the area of security and network security. Open topics can be found here. The current research theme for honours projects is described here (slides).

I also offer scholarships/internships within three programmes:

Prospective PhD students

If you want to do a PhD with me, please contact me several months before the application deadline and take the time to find out what I am doing before proposing a research topic. I delete emails where the sender makes no attempt to understand what I am doing and how this fits with their research plans.

I always have one or two ideas for PhD topics. PhD students at USyd are expected to be competitive for a scholarship. Sometimes topics can be done in collaboration with Data61 - these come with an extra top-up scholarship.

Current students

I am currently an advisor to the following students, working on a range of topics:

  • Jiaan Guo (PhD student, with Alan Fekete) - Internet security
  • Christopher Natoli (PhD student, with Vincent Gramoli) - Blockchain measurement
  • Lexi Brent - Internet security
  • Ilya Nikolaev (Master by Research) - Blockchain security
  • Victory Wang (Honours) - Internet security
  • Jonathan Yan (Honours) - Software security
  • Andrew Yang (Engineering Project) - Software security
  • Joshua Murray (Honours), with Vincent Gramoli) - Blockchain security

Graduated students

  • Rabia Chaudry (PhD student, with Alan Fekete) - Performance of cloud technology
  • Gordon Draper (Master)

Teaching

I am teaching the following units in S2 2017:

I am also the unit coordinator for:

I am a co-lecturer at the University of New South Wales in S1 2017:

TSP & SSP

I am the School of IT’s coordinator for the Talented Students Program (TSP) and Special Studies Program (SSP).

The TSP program is for excellent students doing a science degree. Admission is governed by the rules laid out by the Faculty of Science. Eligible students will receive an invitation by the responsible Associate Dean. The School of IT offers computing-related projects within the TSP. These are the same in nature as the projects offered within a different program, the School’s SSP, which is described below.

The SSP of the School of IT is offered to all students (not just those in an IT degree) who have a strong interest in computing and who are high performers. The entry criteria are:

  • First year students: an ATAR of 99 or higher
  • Second and third year students: an HD average in IT units of study (INFO, COMP, ISYS codes) and a Distinction average in non-IT units of study

For students of degrees offered by the School of IT, admission to the SSP is by invitation, sent out at the beginning of each academic year (late February). Students of non-IT degrees must apply directly with me if they meet the criteria. Students of IT degrees who began their studies during the academic year may choose this way of applying, too.

If you are interested in doing a TSP or SSP project within the School of IT, our offerings can be found here.
