Group Leader

Jun. Prof. Dr. Cosimo Posth

Cosimo Posth focuses his research on the genetic reconstruction and dispersal history of archaic and modern humans through the DNA analysis of ancient human remains. After studying Natural and Anthropological Sciences in Florence (Italy), Cosimo Posth received his doctorate from the University of Tübingen in 2016. In his doctoral thesis he was able to show that early modern humans and Neanderthals admixed more than 200,000 years ago. He also revealed population expansions and contractions of European hunter-gatherers during the last Ice Age. Subsequently, he started his post-doctoral research activity at the Max Planck Institute for the Science of Human History in Jena (Germany) where, in 2019, he became leader of the Human Paleogenomics group. Since April 2020, he is appointed Junior Professor for Archaeo- and Palaeogenetics at the University of Tübingen and Senckenberg Centre for Human Evolution and Palaeoenvironment in Tübingen (Germany) ...see more

Postdoctoral Researchers

Dr. Maria A. Spyrou

Postdoctoral Researcher

I am a postdoctoral researcher broadly interested in the evolution and history of infectious diseases as well as on how past epidemics/pandemics have shaped human societies. I approach these topics through genetics, and specifically through the investigation of pathogen DNA traces in ancient human remains as well as through the reconstruction and evolutionary analysis of whole ancient pathogen genomes from various archaeological contexts. Among a number of topics, my work has largely focused on tracing the history of the plague pathogen, Yersinia pestis, from as far back as the Late Neolithic and Bronze Age periods, as well as from its infamous historical eruptions during the First and Second Plague Pandemics. ...see more

Dr. Michal Feldman

I am a postdoctoral researcher with a main interest in the study of past human populations by the reconstruction and comparative analysis of genomic data. Genetic material isolated from archaeological skeletal remains can teach us many things about the evolution, mobility, health and behavior of prehistoric and historic people. This way of recording the past is especially useful when written records are not available. Mostly, my work has focused on the prehistoric Near East, from as early as the Mesolithic and up until the late Iron Age. More recently, I have been involved in the study of mobility and social structure in context of the first populations of the southwest Pacific islands. ...see more

PhD Students

Kim-Louise Krettek, M.Sc., B.Sc.

After finishing my master’s in biological Anthropology with a focus on osteology, I joined the Archeo- and Paleogenetics group as a PhD student. My project focuses on the population history of South America assessed through the lenses of ancient DNA, which gives us the unique opportunity to study the demography of ancient populations . With my research I hope to shed light not only on how, when and by whom the southern American sub-continent was populated, but also on human interaction with the encountered environments.

Arianna Weingarten, M.Sc.

I received my undergraduate degrees from the University of California Santa Cruz, where I double majored in Biology and Anthropology/Earth Sciences. Following this I completed my Masters in Archaeological Sciences, specializing in paleogenetics, at the University of Tübingen, where I am currently a PhD student. Recent developments in ancient DNA technology have provided the opportunity for us to study a growing number of genomes from the Middle Pleistocene. The fossil record demonstrates that this was not only a pivotal period in human evolution but also that many modern-day mammals became established then. My research focuses on employing aDNA and ZooMS analysis to gain a novel perspective on speciation, hominin subsistence and paleoenvironment during the Middle Pleistocene in Europe.

Orhan Efe Yavuz, M.A.

I did my undergraduate in Physics at the University of Pennsylvania, in the US, and finished my Masters in Archaeology at Koç University in Istanbul. I am interested in how genomic data and other biological material can reveal us about who we are and who we were. A long-run goal of mine is to integrate general human biology of both present and the past into today’s solutions. In the past, I worked on the genomic data from Iron Age Anatolia and I am currently working on ancient DNA data across the broader Mediterranean.

Student Research Assistants

Charoula Maria Fotiadou, M.Sc., B.A.

I completed my Bachelor of Arts in History and Archaeology at the University of Ioannina, Greece. During my Master in Archeological Sciences here in Tübingen I focused on Paleoanthropology and the connection with Paleogenetics, with a special interest on Neanderthals. I am currently working on the demographic history of Neanderthals using mitochondrial DNA data. As part of the Paleogenetics team and a HIWI (research assistant), I am responsible for data processing and analysis, as well as the sampling of ancient DNA from teeth and petrous bones of both human and animal material.

Kelsey N. Moreland, B.Sc.

I received my Bachelor's in Genetics and Genomics from the University of Texas at Austin in 2020 where my two research theses were on the population genetics of the Common Redshank across its range (research performed at the National University of Singapore) and on the population genetics of the giant starlet coral, Siderastrea siderea, in the Belize Barrier Reef system. Broadly speaking, I am interested in interdisciplinary evolutionary genetics research with a particular interest in extinction dynamics and hominin impact on their environment. In my MSc thesis here in Tübingen, I hope to contribute to the body of knowledge for woolly mammoth ancient genetic research. As a research assistant (HiWi), I am responsible for performing molecular labwork and for the team’s media and data storage systems.

Laboratory Staff

Ella Reiter

After my training as a medical-technical laboratory assistant, I worked in the central laboratory of the Tübingen University Hospital for over two and a half years. I have been part of the Archeo- and Paleogenetics working group since 2014 and I am responsible for several aspects such as laboratory organization, equipment maintenance, technical implementation of protocols, assistance in laboratory courses for students and work on projects in the clean room as well as in the molecular biology lab. In parallel to my job, I am currently studying molecular and technical medicine at the Hochschule Furtwangen and would like to focus my bachelor thesis on optimizing laboratory methods for ancient DNA research. ...see more
