Dr Janaina Avila

Honorary Lecturer

Dr Ávila has a PhD in Earth Sciences (2011) from the Australian National University (ANU). She held postdoctoral appointments at the University of São Paulo from 2011 to 2013 and ANU from 2013 to 2014. Between 2013 and 2014, she was a Postdoctoral Fellow under a Research in Business grant from the Australia Department of Innovation. During that period, she worked in partnership with the RSES SHRIMP team and the Australian Scientific Instruments (ASI) scientists in a range of subjects related to improvements in performance of measurements of stable isotopes in the SHRIMP instruments (SHRIMP-II and SHRIMP-SI). As a Postdoctoral Fellow (from March 2013 to May 2014) and as a Research Fellow (from June 2014 to February 2021) at RSES, Dr Ávila provided strategic advice and support to a wide range of multidisciplinary research projects, from application of stable isotopes to constrain the evolution of the early solar system, atmospheric conditions in the Archean, fluid migration in petroleum systems, continental weathering, and more recently in the field of archaeological sciences. 

Dr Ávila is currently a Research Fellow at the Griffith Centre for Social and Cultural Research (GCSCR) at Griffith University. She provides technical expertise in the acquisition and interpretation of in situ measurements of oxygen isotopes obtained in primate teeth. The oxygen fossil record obtained from the measurement of primate teeth will help the construction of fine-scale ancient climate seasonality and its impact in human and primate evolution. The research is funded by the ARC Discovery grant "Constructing robust climate proxies to explore human and primate evolution" lead by Prof Tanya Smith from the Griffith Centre for Social and Cultural Research (GCSCR) at Griffith University.

Qualifications

Ph.D. Cosmochemistry/Planetary Science, 2011, ANU
M.Sc. Earth Sciences, 2005, UFRGS
B.Sc. Geology, 2003. UFRGS

Research interests

Dr Ávila research centres around the application of ion microprobes to the understanding of the isotopic nature of terrestrial and extraterrestrial materials at the microscale. In particular, she is interested in new analytical developments and applications that extend the use of in situ isotopic measurements in earth and planetary sciences. Current areas of interest include: (1) environmental and biological evolutions on early Earth, and their influences on the chemical evolution of the atmosphere and oceans, (2) factors influencing isotopic fractionation (mass-dependent and mass-independent fractionation) associated to sulfur and oxygen isotopes in terrestrial and extraterrestrial materials, (3) sulfur and oxygen isotopic signatures of biological processes, and (4) technique development and innovation of in-situ measurements of stable and radiogenic isotopes using the ion microprobe.
