Mass spectrometry–based approaches to biological anthropology

 

Abstract

Biological anthropology seeks to understand the diversity, evolution, and ecology of humans and our primate relatives. However, the challenges of working with non-invasive and culturally important materials have limited the application of molecular methods in the field. Recent advances in mass spectrometry and the isolation of biomolecules from degraded samples have opened the door to answering previously unknowable anthropological questions. First, non-invasive primate ecology can be expanded through the use of quantitative fecal proteomics from free-ranging populations by integrating host physiological, dietary, and gut microbial data. Second, paleoproteomic methods are opening a window into deep-time molecular phylogenetics, advancing molecular evolution beyond the limits of ancient DNA. Third, traditional food preservation techniques vary widely across human cultures. By integrating mass spectrometry with cultural anthropology, we can reveal how subtle distinctions in taste and texture are associated with deeply rooted cultural preferences.

 

 

Biosketch

Joseph is an Assistant Professor (Professeur adjoint) at the Université de Montréal, where he leads the Molecular Anthropology and Primatology Lab. His research program examines the diversity and adaptive evolution of primates, humans, and their commensal microbes. The Orkin Lab specializes in the application of multiomic tools—genomics, proteomics, and metagenomics—to free-ranging primate populations using non-invasive biomaterials, extinct primates through the study of ancient biomolecules, and human dietary diversity through the biocultural analysis of fermented and preserved foods. Joseph earned his PhD in anthropology from Washington University in St. Louis and completed postdoctoral research at the University of Calgary and the Institut de Biologia Evolutiva (CSIC–UPF) in Barcelona, Spain.

Groupe de discussion en spectrométrie de masse de Montréal (GDSMM)

Le groupe de discussion sur la spectrométrie de masse de Montréal (GDSMM) est un organisme à but non lucratif qui offre un forum favorisant les interactions locales, nationales et internationales entre les scientifiques oeuvrant en spectrométrie de masse. Le GDSMM organise des séminaires scientifiques et des forums de discussion présentant les derniers développements en recherche fondamentale et appliquée en spectrométrie de masse. Une réunion annuelle du GDSMM qui regroupe les étudiants et les post-doctorants a lieu à Montréal chaque printemps et offre une opportunité unique de réseautage en plus d’accroitre la visibilité et la sensibilisation aux contributions locales en spectrométrie de masse.

Montreal mass spectrometry discussion group (MMSDG)

The Montreal mass spectrometry discussion group (MMSDG) is a not-for-profit organization that provides a forum to promote local, national and international interactions among scientists involved in mass spectrometry. MMSDG sponsors scientific seminars and forums to present the latest developments in basic and applied research in mass spectrometry. An annual MMSDG meeting that regroups students and postdoc is held every spring in Montreal, and provide a unique networking opportunity to participants and enhance the visibility and awareness of local contributions in mass spectrometry.
