Otago Students' Geological Society (OSGS)

The Otago Geological Students Society is a University club that aims to introduce and educate people in geology in a fun and interactive way. The club has many different trips throughout the year ranging from beach trips to skiing trips, all of which include both geology and non-geology students. If you have any questions or would like to join the club please don’t hesitate to contact us.

Caitlin Hall imageCo-President

Caitlin Hall

Hi team! I’m Caitlin, and I’m completing my Masters in Palaeoclimatology, after completing an Honours in Antarctic Geophysics last year. Once again, I am your OSGS Co-President for 2020. My main role this year is to coordinate the rest of the committee and help to organise awesome events that are fun for everyone! Myself and Lachie are your main point of contact for all things Geology (incl. Marine Science, Zoology, Genetics and more!). If there are any concerns with OSGS events or the committee, come see us, we’re always happy to help!

Lachie Scarsbrook

Hi, I’m Lachie and I’m your OSGS co-President for 2020 alongside Caitlin! I’m a Geology/Zoology Masters student in my thesis year; focusing on understanding how human colonization and climate change have impacted Aotearoa’s unique lizard species through the use of ancient DNA. My role in OSGS involves a lot of organisation and delegation (amongst the committee) to ensure you all get some wicked experiences, sick merchandise and fun events throughout the year! I’m looking forward to not only working with our new team, but getting to know all our new members!

P.S. we are going to come in hot with events next year so be ready!

Naomi Ahern

Hey there! My name is Naomi, I’m originally from Boise, Idaho, but moved over to NZ to attend uni here at Otago. I’m a 3rd year geology and GIS student, and I’ll be your international representative as well as one of the trip secretaries for the 2020 year. If you’re an international or exchange student I’ll be your point of contact, so if you have any questions about OSGS or just Otago, in general, I’m your gal. I’ll also be helping with organising trips, so any questions about upcoming trips, as well as any ideas for cool places we could visit can come either to me or to Nadine, our other trip secretary. Super stoked for a fun year of geological shenanigans!

Hi! I’m Tilly, and I’m super excited to be the social rep for OSGS for the second time running. Next year I’ll be heading into the first year of my Master's degree, with a focus to find a potential high tech solution for carbon sequestration along the Dun Mt Ophiolite belt in Southland. My heart lies in the field of marine geophysics, so if you ever wanna share some of my passion, don’t hesitate to hmu.
