The University of Queensland, Department of Mathematics. B.Sc. (First Class Honours and University Medal) Computer Science and Mathematics, 1994 - 1997. The University of Queensland. Employment Senior Energy Market Analyst, Energy Exemplar, September 2024 – current. - I develop and enhance PLEXOS models for external clients and assist potential clients with navigating the features and interface of PLEXOS (pre-sales). - I led the significant enhancement of Energy Exemplar’s models for the West Australian Electricity Market adding the DFCM (Dynamic Frequency Control Model) and ancillary services trapezia with complex constraints to closely approximate the model. This approach can be used in PLEXOS in WA, NT and NEM markets. - I updated the internal Japan model and work closely with AEMO and clients in WA and NT (both private and government). The implementation work is to more closely model the real-world operation of each market subject to time and resource limits of the client. Research Fellow and Affiliate, University of Queensland, July 2019 – current. Affiliate, University of Newcastle, July 2021 – current. - In the Centre for Energy Data Innovation, I led the collection and analysis of large amounts of energy data collected from meters; in particular from a 20,000 device setup in Queensland installed by Luceo Energy working with Energy Queensland. I perform clustering and forecasting using the data and set up an observatory to share anonymized data publicly with researchers. I won an IEEE international energy forecasting competition for solar generation and building energy use at Monash. I developed models and performed data analysis for the Gas and Energy Transition Research Centre and the School of Business. - Published extensively on the cybersecurity of energy data; the influence of land use, weather and temporal variables, gender, and hilliness on international bike sharing schemes and e-scooter schemes; breaking unsolved historical classical ciphers with modern techniques; and improving previous results in combinatorics and graph theory. Regularly published on “The Conversation” website to explain my research to the general public. I used C, R, Python, SQL and Gurobi for development. Data Scientist, Redback Technologies, July 2016 – June 2019. - Prediction of solar and load data on a large network of inverters. Development of algorithms in R for battery scheduling and optimization, embedded network operation and virtual power plants. Data cleaning, outlier detection and statistical analysis. Senior Epidemiologist, Preventive Health Branch, Queensland Health, July 2015 – June 2016. - Analysis of survey data and burden of disease data for the biennial Chief Health Officer’s Report and other reports. STATA programming. Senior Research Officer, Health Protection Branch and Communicable Diseases Branch, Queensland Health, December 2015 – June 2016. - Epidemiology of food-borne illness outbreaks involving salmonella and campylobacter Advanced Research Officer, Health Protection Unit/Branch, Queensland Health, February 2014 – December 2015. - Analysis of public health data and report preparation; finding public health datasets to perform preventative health programs rather than reactive health programs; administration of Department of Health’s ArcGIS Online system; developing and analysing public health targets and key performance indicators. Health areas included asbestos, lead, Aboriginal and Torres Strait Islander health, food-borne illnesses, medicines and poisons, and water programs. Analysing epidemiology of food-borne illness outbreaks and statistical analysis of areas including asbestos and food.
