We are an integrative research group that uses stable isotopes as a central tool in basic ecological studies (from population to ecosystem levels), but especially that applies this knowledge on environmental assessment and forensic science combining isoscapes with genetics, chemistry, big data, remote sensing and modeling in our research initiatives.


We are committed to providing high-quality research on stable isotope data interpretation to further knowledge in the environmental sciences for the Neotropics.

Here, we develop a new machine learning approach to ascertain a finer‐scale understanding of geographic differences in soil δ15N, using the South American continent as a test case.  The random forest machine learning framework showed to be a great opportunity to explore a broad array of ecological, biogeochemical, and forensic issues through the lens of soil δ15N.


Next Events


On September 23, 2020, the official launch event of the UFPR Center for Forensic Sciences will take place. The event will be online and will be attended by professionals from the public security area and researchers working in Forensic Sciences. The complete schedule and the link for registration will be released soon on the site https://ccf.c3sl.ufpr.br/


The 12th International Conference on the Applications of Stable Isotope Techniques to Ecological Studies will be held in the beautiful town of Gaming, Austria, from June 20-26 , 2021.


The 22nd meeting of the International Association of Forensic Sciences (IAFS) will take place between 17-21 May 2021 in Australia.

InterForensics is the largest forensic conference in Latin America. In 2021, we will meet in Curitiba / PR to hold another event where the most relevant and current topics in the field of Forensic Sciences will be discussed.

On july (7/29/2020) another edition of the APCF Dialogues webinar series took place with the theme “Science against crime: far beyond discourse”. The debate included the federal criminal expert and former PF Technical-Scientific Director, Fábio Salvador; the professor and researcher in forensic isotopes, Gabriela Nardoto; director general of the Scientific Police of Paraná, Luiz Rodrigo Grochocki; and the president of the National Association of Federal Criminal Experts (APCF), Marcos Camargo. Watch in full:

The National Network of Forensic Isotopes (renifbrasil.org) promoted, from July 6 to 10, 2020, the 2nd edition of the National Workshop on Forensic Isotopes. More than 200 people participated in the event, which included 44 hours of programming, 10 short courses and 20 lectures. The workshop brought together federal and state criminal experts, researchers, students and other professionals working in the field of isotopic science, in addition to representatives from 8 other countries.
