Dr. Matthew Peros

Director of Laboratory

I am a broadly trained physical geographer working at the interface between the climatological, ecological, and archaeological sciences. My research seeks to answer fundamental questions within two broad areas: (1) what have been the driving forces behind climate and landscape change during the Late Quaternary? and (2), how has the natural environment constrained/provided opportunities for cultural and biological change? To address questions in these areas, I use a field- and laboratory-based approach, integrating information derived from geological (e.g., sedimentological, geochemical) and paleoecological (e.g., palynological) investigations with archaeological and paleontological data. At present, my regional specializations include eastern Canada and the Caribbean, although I have also worked in high-latitude (northern) environments.

Sydney Moser

Sydney Moser

MSc candidate, Geography, Environment and Geomatics, University of Ottawa (co-supervised with Dr. André Viau).

My master’s research focuses on reconstructing Holocene climate dynamics in the Caribbean, especially as it relates to understanding interactions between hurricane activity and droughts. I will be doing this as part of a collaborative project with the Wood’s Hole Oceanographic Institution, analyzing a sediment core collected from offshore Haiti, using a multi-proxy approach of grain size analysis, XRF core-scanning, and other indicators.

Martin Saint-Michel, P.Eng

Martin Saint-Michel, P.Eng

MSc candidate, Physics and Astronomy Department, Bishop’s University (co-supervised with Dr. Lorne Nelson, Physics and Astronomy Department)

Cycles and patterns in climate are my main interests. My perspective on the study of climate comes from the principles of physics and I like to study how the laws of nature interact to create what we observe in the real world. I am particularly interested in nature’s capacity to generate rapid radical changes in the climate. The self-similar patterns produced by pollen and other proxies and their relation to biodiversity trigger my curiosity.

Mercedes Liedtke

Mercedes Liedtke

MSc candidate, Geography, Environment and Geomatics, University of Ottawa (co-supervised with Dr. André Viau)

Currently, my master’s research is focusing on the investigation of climate impacts in the Caribbean during the Holocene. The specific project that I am undertaking involves the stable isotopic analysis of a speleothem from Western Cuba. With these results, a long-term precipitation record for Cuba will be constructed.

Felipe Matos Pupo

PhD candidate, Bishop’s University
Auxiliary Professor, University of Ciego de Avila, and Research Scientist, CIEC, Cuba

My research goals regarding climate change are to: (1) seek answers regarding the drivers that trigger climatic changes, focusing on the contribution of both anthropogenic and natural phenomena; (2) assess the connection between biological and sociocultural variations and environmental changes in the corresponding historical context, particularly the paleo-aboriginal one; (3) study the relations between climate change and meteorological hazards.

Claire O’Neill Sanger

Claire O’Neill Sanger

MSc candidate, Geography, Planning and Environment, Concordia University (co-supervised with Dr. Jeannine-Marie St-Jacques).

My core research interests are forest dynamics in Canada as well as environmental management and philosophy. My master’s research, under the co-supervision of Dr. Peros and Dr. St-Jacques, involves studying pollen from lake sediment cores in order to reconstruct forest changes over the past millennium in southern Québec. With the resulting paleo-environmental records we will attempt to determine if recent environmental variability is caused by global warming.

Zachary Masson

Zachary Masson

MSc candidate, Geography, Planning and Environment, Concordia University (co-supervised with Dr. Jeannine-Marie St-Jacques).

My research interests involve studying prehistoric extinctions in the Neotropics, climate change, and pollen analysis. For my master’s thesis I will be examining microfossil indicators of extinct herbivores, such as sloths, from an underwater cave in Cuba, and relating the timing of this to evidence for past climate variability and human occupation to test hypotheses concerning ancient extinctions.

Joao Gabriel Martínez López

My main research interest concerns the taphonomic interpretation of deposits of fossil vertebrates and ancient humans. I use Taphonomy as a basic principle to study the natural and anthropic factors (mechanisms of taphonomic alteration) that influence the origin and formation of deposits, and the state of conservation of bone remains, and obtain data that can correlate certain paleoenvironmental factors that could be responsible for it.

Anna Agosta G'meiner, MSc

Anna Agosta G'meiner, MSc

My research interests focus on the impacts of Quaternary climate change, particularly on vegetation, sea level rise, and human activity. Using palynology, and other paleoecological indicators, I reconstruct past environments and examine environmental changes through long timescales. Currently, I support the lab in various projects, including developing a macro charcoal record of a site in northern Cuba.

Postdoctoral Fellows

Dr. Leeli Amon-Veskimeister, winter 2017

Leeli’s research focuses on vegetation dynamics, in particular, the functional and phylogenetic diversity of sedimentary pollen and plant macrofossil data. This is done by evaluating the methods and associations with past climate and human impact. She received a PhD from Tallinn University of Technology and Tartu University, and an MSc from Tartu University. At Bishop’s, Leeli worked on understanding the late Glacial vegetation and climate history of southern Quebec through plant macrofossil analysis.

Dr. Shawn Collins, 2015

Shawn’s research focuses on karst topography and the sedimentary sequences recorded in anchialine caves and cenotes. Harsh limnological conditions promote conformable sedimentary records which can be utilized as a proxy for a number of geoscience and archaeological applications. His research focused on interpreting the ancient sedimentary record by studying the external forcing mechanisms which control sedimentation in these unique environments. He received a PhD and MSc degree from McMaster University. While a member of the PerosLab, Shawn worked on the geochemical analysis of a sediment core from Cenote Jennifer, Cuba, using XRF core-scanning data.

Completed Ph.D. and M.Sc. Students

Frank Oliva, PhD
University of Ottawa (co-supervised by Dr. André Viau)

My PhD research was on paleotempestology, the study of past tropical cyclones using geological proxy techniques, which is a growing discipline that utilizes data from a broad range of sources. I pushed the boundaries of paleotempestology in Nova Scotia by going beyond “established proxies”, such as grain-size analysis, loss-on-ignition, and micropaleontological indicators. During my PhD, I applied more advanced geochemical analyses, such as X-ray fluorescence (XRF) core scanning and stable isotopic geochemistry to generate new paleotempestological records from Atlantic Canada.

Anna Agosta G’meiner, MSc
McGill University (co-supervised by Dr. Gail Chmura)

My master’s research focused on investigating climate change impacts in the Caribbean region during the Holocene. A sediment core from a flooded sinkhole on Cayo Coco, Cuba was extracted and provided records of vegetation change, climate change, storm impacts, prehistoric human impacts on the environment, and sea level changes. Pollen analysis was the primary proxy developed to identify past changes in regional vegetation and to examine to what extent the Little Ice Age, the Medieval Warm Period, and human impacts recorded in other Caribbean locations are detectable in the pollen record.

Benjamin Marquis, MSc
Université de Sherbrooke (co-supervised by Dr. Mark Vellend)

The fundamental question that was the focus of my master’s research was: are species more sensitive to climate change at their distributional range limits than in the “center” of their ranges? To assess this question, I used dendroecological techniques (tree rings) to determine climate-growth relationships of sugar maple and birch trees along an altitudinal gradient at Mont Mégantic, southern Québec. As well, I tested whether tree growth increased in recent decades as a result of changes in climate. This research project will allow a quantitative test of the hypothesis that species at their distribution range limits are more sensitive to climate.
