Alexander P. Wolfe, BSc (Western Ontario), PhD (Queen's):

Ryan McKellar, Ph.D. 2011, MSc, BSc (Hons. Paleo.), University of Alberta; NSERC postdoctoral Fellow, Universities of Kansas (Division of Entomology) and Alberta;
1) Stratigraphy and systematics of Ordovician phacopid trilobites;
2) Arthropod taphonomy;
3) Amber and fossil insects, especially parasitic micro-Hymenoptera of Cretaceous and Paleogene age;
4) Stable isotopes of modern and fossil conifer resins, history and fate of plant exudates, and chemotaxonomy.

Dr. McKellar defended his PhD thesis on September 2, 2011
. His dissertation, entitled "Paleobiology of Canadian amber: an exceptional record of Late Cretaceous Hymenoptera, with contributions to other taxa and the study of amber", was well received and aptly defended. Most of the thesis is published (see paper titles here), culminating with a paper in Science that has earned him notoriety for his contribution to fossil feathers and to the Late Cretaceous vertebrate fauna of southern Alberta. The whole feather team was tickled upon learning that the paper would fly, largely because publishing on amber can be a sticky issue. Ryan was also awarded the Dean's award for top Ph.D. dissertation in the Faculty of Science for 2011.


Emma Jones
, M.Sc. 2013, BSc Geology, Mary Washington University:
Spectroscopic analyses of sediment charcoal for reconstructing fire history from lake sediments. Emma successfully defended April 15, showing that (a) counting charcoal the old-fashioned way can be supplanted by spectroradiometry and (b) the Yellowstone 1988 fires were the largest since the mid-Holocene.

Heather Mosher, BSc Biology and Earth Science, St. Francis Xavier University, MSc 2012:
Heather defended November 19, 2012: through the eyes of a tree.
Dendrochemical records of atmospheric pollution and recent climate change in western North America

Nathan Ballard, MSc 2011, BSc Geology, Alberta:
Internal phosphorus generation from lake sediments in Alberta prairie lakes; measuring and modeling porewater bioinorganic chemistry; organic matter diagenesis; eutrophic lake diatoms; First Nations environmental issues
Band: Millionaire seeks lady
Nathan successfully defended his M.Sc. April 17, 2011. The thesis was entitled "Mechanisms and algal ecology of internal phosphorus loading in alkaline lakes". Nathan did an admirable job of tracking P, Fe, S, Mn, N in lakes that are both warming and eutrophying fast (can you say Microcystis?), always retaining his stoichiometric balance.

Colin A. Cooke, PhD 2010, MSc Pittsburgh (Earth & Planetary Science), BA Alberta (Anthropology). Colin is presently an Interdisciplinary postdoc at Pittsburgh ( Colin's focus has been the archaeometallurgy of the Andes; sediment metal records; prehispanic mercury use, and avoiding lab work. Now, he is also interested in the carbon cycle, raising children, and avoiding lab work. Colin obtained his Ph.D. April 6, 2010 for a thesis entitled Reconsidering the preindustrial mercury cycle using lake sediment archives. This was a well-conceived and well-received effort that failed to put the committee asleep. You can peruse Colin's details here.

Will O. Hobbs, PhD 2008 (BSc British Columbia, MSc Trinity Dublin).
Currently assistant research scientist at the St.Croix Research Station, Science Museum of Minnnesota; Marine on St.Croix;;
Paleolimnology of alpine lakes, salmon-derived nutrients, climate change, hot-spring diatoms, dissoluton kinetics, reconstructing the limnological consequences of Irish potato famines, drought history, making negative results look better with fancy stats and graphs. Cool publication: Hobbs, W.O. et al, 2010. Quantifying recent ecological changes in remote lakes of North America and Greenland using sediment diatom assemblages. PLoS ONE 5: e10026. PDF
