Not Just Outreach: How Public Engagement Builds Better Scientists A/2-A214 - Velika predavalnica
A/2-A214 - Velika predavalnica
JSI
Outreach programs are typically designed to benefit public audiences, but they can also be powerful training grounds for researchers themselves. At the ARC Centre of Excellence for Dark Matter Particle Physics and OzGrav in Australia, we intentionally use outreach and education programs as opportunities for early career researchers to develop the “soft skills” that are critical for modern scientific careers.
This talk will share how we integrate communication, mentoring, leadership, and collaboration training into programs including the OzGrav Outreach Ambassadors initiative, the Regional Partner Schools program, HERA student balloon research projects, and dedicated professional development sessions at collaboration meetings. These experiences allow researchers to practice communicating complex ideas to diverse audiences, lead hands-on activities, mentor students, and explore career pathways in science communication and outreach.
By embedding researcher development within authentic outreach experiences, we have found that these programs strengthen both the quality of public engagement and the confidence and capability of the researchers involved. This presentation will highlight practical approaches, successes, challenges, and lessons learned that may be transferable to outreach programs across the international particle physics community.Speaker: Jackie Bondell -

(Optional) Visit to the JSI Research Reactor Centre
Bus departure: 8:15 sharp in front of the JSI
You will visit our institute's research nuclear reactor Triga and the only accelerator in Slovenia Tandetron. They are situated at the outskirts of Ljubljana at the JSI reactor center. The full trip will take about 3 hours. After about 30 min bus ride we will reach the JSI reactor center where you will split in multiple groups. The visit will take take about 2 hours. Then you will return by bus to the institute or city center by 12:30. Note that you will visit supervised radiation areas.
