Fenja Brodo, Ph.D.

Research Associate, Zoology
Work is underway on the Inventory of the Crane Flies (Diptera: Tipulidae, Limoniidae and Cylindrotomidae) of Churchill, Manitoba, in collaboration with Chen Young, Ph.D., (Carnegie Institute, Pittsburgh, PA). A project started years ago, a monograph on the subgenus Tipula (Arctotipula), is also now in progress, as is another on the genus Angatoripula. My participation in local BioBlitzes, especially night-time collecting, has increased the number of crane flies found within the Ottawa district.

Jarmila Kukalovà-Peck, Ph.D.

Research Associate, Zoology
Research will continue on the evolution and diversification of insect wings and other structures, at the level of taxonomic order. The approach is to deliver objective and easily verifiable evidence on concrete wing characters to resolve the much disputed phylogenetic tree of winged insects (Pterygota). Results will be published in an atlas of detailed characters of the wing structure of modern orders.

Jean Lauriault, B.Sc., C.S.E.

Museum Associate
Jean Lauriault is an environmental specialist and the author of the Identification Guide to the Trees of Canada. For the past 20 years, he has been travelling to Mexico on a regular basis for the conservation of the monarch butterfly. He participated in the development of the North American Monarch Conservation Plan. He produced videos on his work with the monarchs for the media.

Through ecotourism in Mexico and Canada, he reached a large number of people and sensitized them to the importance of conservation of the monarch.

In addition, Lauriault is a professor-trainer for the conservation of the monarch biology, as well as the preservation of trees. In collaboration with the Agence de la Francophonie and the Université de Montréal, he has provided biodiversity training in Morocco, Tunisia, Guinea, Mali, Burkina Faso, Chad, Gabon, Togo, Benin, Ivory Coast and Vietnam.

Stewart Peck, Ph.D.

Research Associate, Zoology
Peck will continue research on systematics of beetles and other arthropods, with emphasis on cave dwellers, Leiodid beetles (small carrion and fungus beetles), and beetle of the West Indies. Present research is on the taxonomy of the small carrion beetle genus Dissochaetus from Mexico and Central America. In this geographic region, about 20 species have been described, but each is presently known only from very few specimens and localities. Now, collections of about 15 000 specimens from hundreds of localities will contribute greatly to understanding the species and their distributions.

Claude Renaud, Ph.D.

Research Associate, Zoology
Renaud is an ichthyologist and was a Research Scientist at the Canadian Museum of Nature for almost 30 years. His area of expertise and research are lamprey (order Petromyzontiformes) taxonomy and systematics, as well as lamprey biology in general.

His programme of research involves fossil and living snakes and lizards (squamates), and takes place in the field and the laboratory. The goal of his research is to learn everything possible about the palaeontology, origins and evolution of squamates, as well as extinct marine reptiles such as ichthyosaurs and plesiosaurs. His study techniques provide data about anatomy, morphology and, in some cases, molecular genetics from specimens collected all over the world.

Steve Cumbaa, Ph.D.

Research Emeritus, Research Associate, Palaeobiology
Cumbaa is a vertebrate palaeontologist whose research is primarily on fossil marine-vertebrate faunas, palaeoenvironments and palaeoecology in western and Arctic Canada. Current projects include

  • the description and analysis of fish, marine reptile and bird fossils recovered from 90 to 100 million-year-old deposits of the Late Cretaceous Western Interior Seaway in eastern Saskatchewan and western Manitoba
  • the description and analysis of 400 million-year-old Early Devonian fossil fishes from deposits along the Anderson River in the Northwest Territories
  • a description of the unique anatomy of a specimen of the giant Late Devonian arthrodire Dundleosteus.

Steve is also an Adjunct Research Professor in Earth Sciences at Carleton University.

Sean P.A. Desjardins, Ph.D

Research Associate, Palaeobiology

Sanja Hinić-Frlog, Ph.D.

Research Associate, Palaeobiology

She has been involved in several, ongoing research projects at the Canadian Museum of Nature since 2009, and is teaming with museum research scientist Natalia Rybczynski, Ph.D., to study the specializations of the skeletons of aquatic birds, considering what is known about their systematics and ecology. She is also working with fellow research associate Steve. Cumbaa, Ph.D., on the systematics of bird-fossil material from Saskatchewan.

Robert Holmes, Ph.D.

Research Associate, Palaeobiology
Holmes is co-supervising a master's student at Carleton University who is working on species of the genus Chasmosaurus; many of the relevant specimens are in the museum's collections. This work will help clarify future work on the stratigraphic occurrence of the chasmosaurine specimens held in the museum's collections and assess how all of the Chasmosaurus specimens in the museum's collections fit into this new taxonomic framework.

Holmes, in collaboration with fellow research associate Michael Ryan, Ph.D., will study ceratopsid specimen CMN8804, identified by Sternberg as Brachyceratops because of its small size. It is possible that this specimen represents a new, primitive, previously unknown subgroup of ceratopsid, and will hopefully expand our knowledge of this important group of dinosaur.

Work continues on a nearly completed description of the postcranial skeleton of Vagaceratops irvinensis that is currently on display. 

Hillary Maddin, Ph.D.

Research Associate, Palaeobiology
Maddin is a palaeontologist and Professor at Carleton University. She studies the origin of the diversity of animals over large time scales, with a special interest in the development and function of the skull, and the evolution of its shape and size. Her work involves the study of both living and fossil species, with a special interest in amphibians.

Michael Ryan, Ph.D.

Research Associate, Palaeobiology
Ryan has an active research program that involves the palaeontology and osteology collections at the Canadian Museum of Nature, with interests in birds, fishes and dinosaurs. He is working with museum research scientist Jordan Mallon, Ph.D., to describe a new ceratopsid dinosaur that was collected by former museum curator Wann Langston, from Alberta. Ryan is working with fellow research associate Steve Cumbaa, Ph.D., in the description of placoderm fishes. Ryan involves several students from Carleton University in his research.

Natalia Rybczynski, Ph.D.

Research Associate, Palaeobiology
Rybczynski is a palaeobiologist who specializes in fossil mammals from the Neogene (~23 to 3 million years ago) High Arctic. Today, the High Arctic landscape of North America is tundra and polar desert. However, the Neogene fossil record preserves evidence of ancient polar forests, and in rare cases, fossil mammals. Her current research collaborations focus on uncovering the evolutionary history and biology of these mammal lineages, many of which are related to modern mammals (e.g., beavers, camels, seals, bears). In addition, she contributes to paleo-environmental research studies which investigate climate and landscape change in the Neogene High Arctic (e.g., PoLAR-FIT: Pliocene Landscapes and Arctic Remains—Frozen in Time).

Robert Gault

Research Associate, Mineralogy
Research will continue on the mineralogy of Mont Saint-Hilaire, Quebec, contributing to a complete re-write of a publication from 1990; since then, the number of mineral species from this world-famous site has doubled to approximately 420. Mont Saint-Hilaire is the type locality of 60 of these species. This collaborative effort will describe each species in detail, including compositional data when possible. The next step is to complete the history, regional geology and the geology of the Mont Saint-Hilaire pluton, to complete maps and various tables and to choose appropriate photographs and SEM images; completion is anticipated in 2017. This publication will be a complete reference for both amateur and professional mineralogists. This project complements Piilonen's Evolution of Alkaline Environments project.

Curatorial assistance continues with the museum's mineral, rock and gem collections in cataloguing the backlog of material, preparing for the eventual transfer of the Geological Survey of Canada's mineral collections to the museum's collection, and in choosing specimens for the new travelling exhibition.
