After a time with Orolia as a maritime Product Line Director, Gwynne worked as a marine consultant with a variety of clients, before becoming the chief executive of the Institute of Marine Engineering, Science & Technology (IMarEST) in June 2020, a position he holds today.

Prior to his current role, Dr Mansell was posted into The Boeing Company (USA) where he worked alongside the Chief Engineer and his leadership team on engineering realignment, innovation supply chain and R&D transformation. This posting provided invaluable experience leading a company through a crisis, as well as the technical and commercial challenges creating innovative products and transitioning them into new capability through industrial supply chains.

From 2017-2019 Dr Mansell was Chief Science Strategy and Program Division and the Acting Chief Defence Scientist (6 mths), where he was accountable for assuring Defence had the Science & Technology (S&T) capability required to meet Defence’s current and future needs. He also has experience leading Defence’s S&T programs supporting Air Force (as Chief Air Operations Division), the Joint Force Domain (as Chief Joint and Operations Analysis Division), and the formation of Contestability Division and the National Naval Ship Building Strategy (as First Assistant Secretary – Strategic Policy and Intelligence Initiatives).

Throughout his career, Dr Mansell has been responsible for all aspects of the technologies that support submarines through their capability lifecycle (including, combat systems, weapons and countermeasure systems, communications and EW, ship control and manoeuvring, hull and mechanical systems, power generation and distribution, propulsion, signatures, force structure modelling, operations analysis and shore based facilities).

In recent years, Dr Mansell has shaped Defence innovation (as the architect of the Defence Innovation reforms announced in the 2016 Defence White Paper and Defence Industry Policy Statement) and Australia’s National innovation ecosystem (where the led the Innovation and Science Australia Taskforce responsible for producing the nation’s 2030 Innovation, Science and Research Strategic Plan titled Australia 2030: Prosperity through Innovation).

Dr Mansell has a deep knowledge of the five-eyes research and development environments through previous postings to the USN’s Naval Undersea Warfare Centre, Canada’s Defence Research Establishment Atlantic, and as Counsellor on Defence Science in the United Kingdom.

Secondly, and continuing, he is an academic of 25 years standing with the University of NSW Canberra. In this environment, which delivers a UNSW university education at the Australian Defence Force Academy, he has served in a range of roles including two terms as Head of School. His research and teaching have predominantly been related to engineering design, naval architecture, and engineering education. With the decision to stand up a full naval architectural discipline at UNSW Canberra, which began in 2022, Warren is the inaugural Program Coordinator and has turned his full attention to its success. Thus, naval architecture has been a consistent thread that has spanned his whole career.

Warren is also well known and respected for his leadership and delivery of highly engaging, experiential learning in his classrooms and beyond, leading to significant, long-term outcomes with local, national and international impact. Examples include being the academic advisor to the Academy Racing FSAE Team, and supporting the Re-Engineering Australia (REA) Foundation STEM outreach programs (e.g. F1inSchools, Subs in Schools) serving as the National Rules Chair and Chair of Judges since 2011. However, it the Warman Design and Build (WD&B) Project since 1998 that in part has defined him, a project that has engaged and influenced more than 68,000 students across 36 Australasian universities during its 36-year life. In recognition, Warren was the 2018 recipient of Engineers Australia’s, A G M Michell Medal, awarded for outstanding service to mechanical engineering.

Following this project, Tim assumed the role of design manager during the construction of the 83m, 86m and 101m Auto Express catamaran designs. When Austal moved into the defence market with the Armidale Class Patrol Boat, Tim led the Austal proposal team. He then moved to the United States to lead the Austal Littoral Combat Ship team as the capture manager. This continued until construction of USS Independence commenced and the US based design team was established. Tim also led the Austal Joint High Speed Vessel team which won an initial ten ship contract. Following his return to Australia, Tim has led the sales and business development of Austal’s domestic and international defence business. Tim’s current title is Design Development Manager and is focused on the delivery of naval and commercial design solutions, including decarbonisation options for the world’s ferry market.
