Dr. Pablo Joaquin Alonso-Muruaga

Assistant Researcher for the National Research Council of Argentina (IGEBA-CONICET); Assistant Professor for the University of Buenos Aires (UBA).

Alumni_ProfilePic_PJoaquin.pngI was introduced to Ichnology by my former professor of Historical Geology Dr. M. Gabriela Mángano, and by my undergraduate supervisor Dr. Luis Buatois at the University of Tucumán, Argentina. This prompted me to pursue the Ph.D. supervised by Dr. Buatois and Dr. Limarino from the University of Buenos Aires.

My research field is related to sedimentology, ichnology and stratigraphy, mainly involving process based sedimentology, trace fossil studies, and its integration into sedimentary facies analysis, in order to reconstruct ancient depositional environments and interpret their possible sequence stratigraphic framework.

Dr. Patricio Desjardins

Regional Geologist, Shell Exploration & Production Company (Texas, U.S.A)


I am a sedimentologist and stratigrapher by background and that is where my passion in geology has been able to flourish. I have a wide experience in clastic and mixed carbonate-siliciclastic systems including a wide range of sedimentary environments, from fluvial to deep water, and everything in between. I strongly believe that subsurface studies need to be anchored to rocks, thus I include to most of in my work packages core and outcrop studies. I specialize in the recognition and understanding of geologic controls on hydrocarbon accumulations and well performance enabling high quality business decisions. I can successfully integrate multiple disciplines across multiple asset and support organizations. I tailor specialist studies to business needs and steer projects toward asset value drivers.

Dr. Javier Dorador

Postdoctoral researcher in the Department of Earth Sciences at the Royal Holloway University of London (UK)

ProfilePics_JDoradorI received my Bachelor degree in Geology and Master in Applied Geology, both of them in the University of Granada (Spain). Then, in 2017 I finished my PhD by the University of Granada (Spain), supervised by Prof. Francisco J. Rodríguez-Tovar. It dealt with the palaeoenvironmental analysis along the Quaternary based on the ichnological analysis of cores from marine sediments. During this period I conducted various stays, including MARUM, (Germany); University of Saskatchewan (Canada); Institut für Geologie und Paläontologie (Basel, Switzerland) and Statoil ASA (Norway) for training.

After that, I was worked for six months as a post-doctoral researcher in the Department of Stratigraphy and Palaeontology from the University of Granada, but nowadays, I am a postdoctoral researcher in the Department of Earth Sciences from the Royal Holloway University of London (United Kingdom). My position is funded by a Newton International Fellowship by The Royal Society and a Marie Skłodowska-Curie Actions Individual Fellowship by the European Commission.

My research line is focused on the ichnological analysis in cores to analyze palaeoenvironmental changes and reservoir properties, with a special interest in contourite deposits.

During my career, I have published 21 research papers, most of them in highly ranked journals, and I have presented my research in more than 20 scientific meetings. I have been also involved as an educator for degrees of Geology and Biology, Master in Geology, and I have supervised one master thesis. I have been also involved in outreach activities, participating in workshops and activities for the general society. Finally, I would like to add that I was awarded by the Jordi de Gibert Award (International Ichnological Association) and the Early Career Research Grant (Spanish Palaeontological Association).

Dr. Richard Hofmann

Postdoctoral researcher

Alumni_ProfilePic_RHofmann.pngI got interested in marine palaeoecology as an undergraduate at Freiberg University (Germany). My later M.Sc. supervisor Dr. Olaf Elicki encouraged me to join a field trip to Jordan in March 2006 where I met Dr. Mángano, and we investigated animal-substrate interactions in Cambrian shallow marine siliciclastics. In spring 2007 I was lucky to join the Lab of Dr. Mángano and Dr. Buatois as a visiting student. Dr. Elicki and Dr. Mángano then supervised my thesis on said Cambrian trace fossils from Jordan which was completed in summer of 2008. In early 2009, I became a PhD-Student in the Lab of Prof. Hugo Bucher and Dr. Michael Hautmann working on Early Triassic marine macrofossils to better understand the recovery from the end-Permian mass extinction. After attaining the degree in late 2013, and staying for a postdoc on Permian benthic communities, I am currently studying diversification patterns of Early and Middle Ordovician benthic communities with projects at the Museum für Naturkunde Berlin (Germany) since 2015. Although ichnology, unfortunately, has never been a main interest ever since the time in Saskatoon, this fascinating field never left me. The ichnological tools developed under the tutelage of Gabriela and Luis are always in my backpack, which enabled me to publish a number of papers along the way.

Currently, I have a research position at the Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET) and a Teaching position at Universidad de Buenos Aires, Argentina. I met Gabriela Mángano and Luis Buatois in 2001 when I was an undergraduate student at the University of Tucumán (Argentina).  Their enthusiasm made me interested on ichnology. Gabriela Mángano and Claudia Marsicano were my PhD. advisers at Univerdidad de Buenos Aires, Argentina and I spent three terms (2007, 2009, 2013) as a PhD student and postdoc at University of Saskatchewan.

I am interested in the interrelationship between animals and their environments, and particularly in how ecosystems and its functions have changed through time in response to major events in the history of the Earth. I use animal-sediment interactions as a proxy for investigating such questions. My projects are currently focused on: (1)  The role of tetrapod footprints on continental ichnofacies models and paleoenvironmental reconstruction; (2)  Implication of tetrapod ichnology in the reconstruction of arid-semiarid environments and ancient ecosystems; and (3) the ichnological evidence of evolution of South American mammals.

Dr. Nic MinterAlumni_ProfilePic_NMinter

Senior Lecturer at the University of Portsmouth

I am interested in co-evolution between life and the planet. My research is at the interface among palaeontology, sedimentology and behavioural ecology; focusing on organism-sediment interactions, both when they were alive (trace fossils) and dead (taphonomy), and what they can tell us about ecosystems through time and their responses to major events in the history of life on Earth. These include evolutionary radiations, colonization events and mass extinctions. My research involves field, laboratory, collections, and database studies; studying organism-sediment interactions ranging from half a billion years old through to conducting actualistic experiments and observations with modern animals, and across deep marine to desert environments. I have been lucky enough to work on world-renowned geological localities, including the Cambrian Burgess Shale of British Columbia, Carboniferous of Atlantic Canada, Permian Robledo Mountains of New Mexico, Triassic Petrified Forest National Park of Arizona, and Cretaceous Dinosaur Coast of Korea.

I graduated from the University of Bristol with a BSc in Geology and Biology in 2003 before going on to complete a PhD on continental ichnology in 2007 from the same institution. I undertook postdoctoral research at the University of Bristol from 2009-2010 and then the University of Saskatchewan from 2010-2012. After my postdoctoral research at the University of Saskatchewan, I took up a permanent lectureship at the University of Portsmouth in 2013 where I am now a Senior Lecturer in Geoscience in the School of the Environment, Geography and Geosciences Portsmouth.

My research at the University of Saskatchewan was funded by a Government of Canada Post-doctoral Research Fellowship under the Canadian Commonwealth Scholarship Programme, and then an NSERC Engage Grant. I worked with Luis and Gabriela on the trace fossil record of the colonization of land and developed methods for quantifying ecospace occupation and ecosystem engineering using trace fossils. We continue to work together on a number of projects, including applying these methods to other important events in the history of life on Earth; as well as experimental work on the effects of transport on the preservation of soft-bodied organisms and allochthonous trace-producers.

Dr. Alina Shchepetkina


Freelance Scientific Editor at Cactus Communications

I am a trilingual (English, Spanish and Russian), field- and laboratory-based sedimentologist and ichnologist. I completed my BSc and MSc in Petroleum Geology and Lithology at the Gubkin State University of Oil and Gas (Moscow, Russia). My MSc thesis helped refine the paleoenvironments of deposition and spatial distribution of reservoir rocks by petrographic characterization and detailed facies analysis of Jurassic and Cretaceous deltaic successions in the Caspian Basin. I also lead and contributed to a diverse array of clastic and carbonate sedimentological projects for various basins of the Russian Federation.

In 2011, I emigrated to Canada to earn a PhD in the fields of sedimentology and ichnology at the University of Alberta (Edmonton, AB), working with S. George Pemberton and Murray K. Gingras. I conducted research in modern coastal sedimentary environments (Petitcodiac River estuary in New Brunswick, Bay of Fundy in Nova Scotia, Netarts Bay in Oregon, and Ogeechee River estuary in Georgia) and ancient rock record (Cretaceous McMurray Fm., Bluesky and Gething Fm.). My work efforts have been recognized internationally and resulted in a number of peer-reviewed publications. In 2017, I secured a position in a competitive Postdoctoral Research Fellowship program (CONICET, Argentina), and moved to the Instituto de Investigación en Paleobiología y Geología (General Roca, Rio Negro) to build a geological model of the continental to marginal-marine Cretaceous Centenario Fm., Neuquén Basin. During the postdoctoral fellowship, I was invited for a 3-month internship to the University of Saskatchewan to work in collaboration with Gabriela Mángano and Luis Buatois.

I also have energy experience, having conducted several internships with the leading Russian and international companies (e.g., TNK-BP, Gazpromneft-NTC, SNGEO, Shell Canada), working as a part-time sedimentologist at the Petroleum Lithology Department (Gubkin State University), as an MWD D&M engineer at Schlumberger, and a scientific consultant for YPF. My research interests span the fields of clastic sedimentology, neo- and paleoichnology, petroleum geology, sequence stratigraphy and petrography.

Dr. Romain Vaucher

Postdoctoral fellow


I am a fieldwork sedimentologist specialized in shallow-marine clastic environments working on both modern and ancient sedimentary systems. My research interests in sedimentology include, but not limited to, paleoenvironments, processes, paleontology, and paleoclimate.

After graduating from the University of Geneva, where I obtained both my BSc (2010) and MSc (2012) degrees, I completed my PhD (2013-10 to 2017-03) at University Claude Bernard Lyon 1 (France). My PhD research involved describing and quantifying the combined influence of waves and tides on siliciclastic sedimentary environments in ancient and modern systems to provide keys to reconstruct these oceanographic processes from ancient sedimentary sequences. Following my PhD, I did my first postdoctoral fellowship (2017-2019) at the National University of Córdoba (Argentina) in collaboration with the University of Saskatchewan (Canada). During this research position, I worked on the tectonic controls on deposition in the Early Paleozoic period of the proto-Andean basin in northwest Argentina. In 2019 (May), I started a second postdoctoral fellowship funded by the Swiss National Science Foundation to work at Simon Fraser University (Canada), in collaboration with National Taiwan University (Taiwan). Since then, my research focuses on climate and extreme weather event impacts on the Western Foreland Basin’s sedimentation in Taiwan.

Dr. Lijun Zhang

Postdoctoral fellow, Associate Professor

ProfilePics_LZhangDuring my bachelor’s (2002-2006) at China University of Geosciences (Wuhan), I was introduced to Devonian trace fossils and marginal marine by my undergraduate supervisor, Dr. Yiming Gong. Over that time, I became interested with the complex and enigmatic Zoophycos, which can provide information about evolution, behavior, and response to the substrate change. This prompted me to finish a Ph.D. at the China University of Geosciences (Wuhan, China) with Dr. Yiming Gong and Deakin University (Melbourne, Australia) with Dr. Guang Shi from 2006-2011. Currently, I am working at Henan Polytechnic University, mainly in trace fossils and their response to the biotic event, e.g. End-Permian mass extinction, Cambrian explosion. I am very proud to join the ichnogroup of Dr.’s Buatois and Mángano as a postdoc from 2016 to 2018.

Ph.D thesis (completed): Geobiology of the trace fossil Zoophycos
