The Dennis Trewin Prize, named after the former Australian Statistician Dennis Trewin AO, is awarded annually by the ACT Branch for outstanding early career research in an area related to statistics and/or data science conducted within the ACT or regional NSW outside Newcastle-Sydney-Wollongong.
This year we have three candidates who will present their work, with a selection panel determining the winner. Each candidate will have 20-25 minutes for their presentation and 5 minutes for audience questions. In partnership with the Australian Bureau of Statistics, monetary prizes totalling $1,000 or more will be on offer and distributed at the discretion of the selection panel.
After the presentations the panel will be given time to deliberate, while those attending in-person will be asked to move outside and will have the opportunity to mingle with the candidates. Once the panel has reached a decision, attendees will be invited back into the room for the announcement of the results.
Also, we will be having an SSA ACT dinner that evening at Badger & Co in the ANU, Health & Well-being Centre, Kambri Precinct, so if you are interested in attending the dinner and catching up with members and friends in person, please see below for RSVP details.
