Abstract

During his visit, Prof. Hubbe will focus on four complementary research activities:a)Work with the PI of the Fapesp JP-Project on the morphometric analysis of CT scans of early Holocene Lagoa Santa skulls, with a special focus on the study of the responses that different anatomical regions of the early skulls from Lagoa Santa (Minas Gerais) show to specific evolutionary pressures in the past. This activities will create the analytical protocols required to collect the morphometric data required to explore the questions about the evolution of cranial morphology among early South American populations (see background section, below).b)Offer a mini-workshop (9 hours, over 3 days) to introduce graduate and undergraduate students to the statistical software R. R is the most used statistical software worldwide, due to its open-source nature and impressive community of contributors. However, it is not user-friendly, and students that do not have a strong statistical background struggle to learn how to use it. Prof. Hubbe has been teaching statistical methods for social scientists for several years and has developed an efficient way to introduce and discuss the basic statistical concepts and use of statistical software for archaeological and anthropological students. Students will leave the workshop with a basic knowledge of the logic of inferential statistics, as well as of the use of R, R-Studio and R-commander, which will allow them to continue developing their statistical skills.c)Interact and establish collaborations with professors and graduate students interested in working with multivariate statistical analyses and morphometric studies. Prof. Hubbe has worked with Prof. Verônica Wesolowski (MAE) and Prof. Mercedes Okumura (IB-USP) as well as some of their students, and his visit will allow him to meet these professors and their research teams to strengthen the international collaboration between USP and Prof. Hubbe's primary institution, the Ohio State University. d)Participate on the 8th Meeting of the South American Association for Paleopathology that is being organized by Prof. Verônica Wesolowski and Prof. André Strauss here at the University of São Paulo. Prof. Hubbe will both present his recent work synthesizing global patterns of biological variation in past humans and act as the chair of the related sessions. (AU)
