Lecturer (fixed term) Computer Science Department, University of Otago January 2018 - November 2018
The Department of Computer Science is a small department composed of 14 full-time academic staff, six service staff, and three teaching fellows. In this position I lectured undergraduate courses on Effective Programming, Object-Oriented Programming and User Interfaces, Linux Network Management, and a post-graduate course on Advanced Databases.
- Take lectures/tutorials conveying computer science concepts and provide appropriate assessment feedback to students from different academic and cultural backgrounds
- Complete administrative tasks in a timely, efficient manner in accordance with the University's policies
- Ensure relevant health and safety protocols are followed in all workplace activities
AchievementsFormal teaching evaluations were 'pretty outstanding [...] with a very good response rate'. All core teaching questions scored median values in the top two levels. The following are some of the comments students left on the evaluation forms anonymously
- I really enjoyed how open Paul was to answering questions. He was also very knowledgeable about the subject which is always helpful.
- Really good communicator, going to Paul's lectures always feels valuable and his verbal explanations help a lot with unpacking and understanding the concepts, really appreciate his depth of explanation in lectures and his patience and thoroughness when helping us in labs
- Paul has a great attitude about the topic and is obviously very passionate about it. I enjoy his teaching style and the way that he interacts with the students. He is also very helpful after class if you have any questions. He is very receptive to students who show enthusiasm on the topics and he meets them with a similar attitude. Having a teacher who is also engaged in the student’s learning is rare and makes for a better learning environment.
Software Engineer Downer Group March 2017 - December 2017
The Downer Group is a company involved in civil infrastructure works across Australia and New Zealand. I designed, developed, tested, deployed and maintained a novel containerised digital signage application to push (in realtime) a wide range of relevant up-to-date content to remote display clients around the country while maintaining integrity and security of the data. Briefly, the application consisted of an AndroidThings client application; a message queue for control commands; a web application and associated database for administration of devices, content hosting, and data gathering and parsing (via asynchronous task queues); and, public key infrastructure to authenticate remote clients.
- Reduced the number of tourist enquiries of a dozen businesses in Te Anau (population 2000) about the status of the only road to Milford Sound (a popular tourist destination), which is often closed at short notice due to avalanches and other hazards common in mountainous areas
- Increased visibility of earthquake recovery efforts by North Canterbury Transport Infrastructure Recovery (NCTIR), the organisation comprised of several government departments and private companies setup to recover from the magnitude 7.8 earthquake that struck Kaikōura in 2016
PhD Computer Science, University of Otago, 2017
Indoor localisation systems are concerned with locating people or devices indoors without the support of GPS. A key challenge is to derive accurate location estimates. The thesis explores, and improves upon, the accuracy of two different signal strength based approaches. The final contribution is to reduce the effort needed to deploy an indoor localisation system via crowd sourcing.
MSc (Thesis Only) with Credit Information Science, University of Otago, 2011
The thesis is an examination of the use of rapidly deployable cell-phone networks for disaster relief efforts. During a disaster, effective communications are vital to coordinate response efforts and to keep civilians informed. We propose and test a system that is aimed at use by civilians without the need for them to have any special equipment apart from a GSM mobile phone.

Real-time Neuro-feedback Phoebe Neo, Department of Psychology, University of Otago March 2017 - November 2017
This research project in the Psychology department aims to discover ways to reduce depressivity. I implemented a real-time neuro-feedback task according to an experimental protocol, and developed programs to analyse the data collected.
Supporting Energy Monitoring At University of Otago Hans Pietsch and David Eyers, Property Services Division and Department of Computer Science, University of Otago July 2016 - December 2016
In this project I worked with a multi-disciplinary team at the University of Otago to collect and collate a variety of energy related measurements from a disparate set of systems (e.g. building management systems, lighting systems, ad hoc sensors) at a high level of geographic (e.g. room, floor, building, and campus) and temporal precision (most commercial systems only persist aggregate data). The prototype system was presented at the Otago Energy Research Centre's Symposium in 2016, and awarded Best Student Presentation.
Accelerometer Gloves Liz Franz, Department of Psychology, University of Otago 2013 - 2014
In this project I designed, developed, and prototyped a set of accelerometer gloves to replace and improve upon a set of gloves that had gone out of production. The design of the new gloves achieved a sample rate of 125Hz (matching the existing pair), while improving upon the comfort level across a variety of different hand sizes and shapes.
