Profile bio
About Liam Costello
Experience in the completion of my law and economics degree has provided me with thoroughly developed and refined skills in writing, grammar, analysis, reading comprehension, macro and microeconomic knowledge, mathematics, coding, programs like Rstudio and Stata, high numerical literacy, and an academic understanding of statistics.Working as an intern and part time market research trainee with 4th Harmonic for a little over a year showed to me firsthand the picture of the defence industry and its related economic inputs and outputs in the Australian and international context. It also gave me the advantage over my age bracket of real experience in a workforce of some of the most competent and knowledgeable peers in defence. They guided me in learning how to code, use programs such as Python, Microsoft Excel, and others, as well as personal knowledge of the military, defence industry, and business etiquette.I have completed all the law courses required for my law degree; I look forward to the conclusion of my economics subjects to allow me to graduate from my double degree in semester two of 2023. I eagerly anticipate fully utilising my capacity to practice law and my economic knowledge to further develop my career.

Market Research Trainee
My primary role in 4th Harmonic has been to exhaustively study the defence industry from top to bottom. This involved researching numerous aspects of Australian defence from the initiatives of the largest firms such as Lockheed Martin or Thales Group to finding any and all companies with connections to defence. I was taught how to use Python coding so we could to the best possible extent automate the unending quantities of data involved in this process. My role has been critical to 4th Harmonic's business model of providing a comprehensive and total view of the Australian defence industry to bolster its strategic management services to companies in defence.
