Lachlan O'Neil is a data scientist, statistician, team leader, and project manager within CSIRO's Energy Systems program. 'From farm to plate', Lachlan's work starts at stages as early as survey design and data collection, right through to the delivery of in-depth analyses with a strong focus on data visualisation for both technical and non-technical stakeholders.

Since starting in November 2016 as part of CSIRO's undergraduate vacation scholarship program, Lachlan's time has been spent researching the residential energy space. A key component of his research has been the consolidation of demographic, built environment, appliance uptake and usage, weather and metered energy data - each often with their own geographic and time series properties to consider.

Lachlan's work has seen him collaborate and deliver for many stakeholders including the Australian Energy Regulator, South Australian Power Networks, Energy Queensland Limited, Horizon Power and Tesla. Most recently Lachlan has lead several projects as part of the National Energy Analytics Research (NEAR) Program, working closely with the Department of Industry, Science, Energy and Resources and the Australian Energy Market Operator. Lachlan's unique multifaceted understanding of residential energy has also allowed him to contribute to high profile releases including the Australian Competition and Consumer Commission's electricity supply & prices inquiry final report (2018).

As for the origin story - Lachlan completed a Combined Bachelor of Computer Engineering and Mathematics, where he majored in statistics at the University of Newcastle. During this time he tutored university introductory programming, programmable logic design and introductory engineering practice as well as high school mathematics. This experience drove him to continually seek simple explanations to complex scenarios, an area where visualisations proved hugely important. Throughout the degree he also picked up experience in electrical engineering, FPGA design, software engineering, telecommunications design, mathematical modelling, statistics and data science.

As fate would have it, Lachlan's time in the energy sector actually started back in his gap year between high school and university. It's in this year he picked up a role at Essential Energy in his home town of Port Macquarie. A sector choice that he would ultimately come back to 5 years later.

Other Interests

Sports - I play soccer on the weekend and follow soccer, AFL, NRL and cricket when I get the time!

Video Games - I grew up playing the Sega Mega-Drive with my brothers and fell in love with my N64 one Christmas (I still have it setup in my lounge room today!) These days I spend my time trying to juggle time between the Nintendo Switch, PS4 and PC!

Board Games - It's nice to get away from screens, and regular board games sessions give me a chance to flex my brain whilst giving my eyes a bit of a rest!

Cats - I own two cats, ask for pictures at your own risk!
