Nathan Ackroyd, PhD - Associate Professor
My wet-lab research is mostly in the area of multi-step synthesis of potentially useful organic or organo-metallic compounds. With Susan Morante, I am beginning to work on the identification of bee hair pigments. Students with a background of CHEM 3103 and/or 3201 may look for a project using their spectroscopy or synthesis skills.
Students who are interested in working, either as a volunteer or for CHEM 5201 during Fall or Winter semesters are welcome to set an appointment to discuss more specifics. Email me at firstname.lastname@example.org.John Chik, B.Sc., PhD - Associate ProfessorMy personal research interests crosses the boundaries between chemistry, physics and biology. I am particularly interested in how the cellular solution environment shape protein structure and function. My main focus is on how osmotic stress/crowding could potentially modulate protein conformation. The primary tool for this research is hydrogen/deuterium-exchange mass spectrometry using Mount Royal’s newly acquired LTQ XL mass spectrometer coupled with the Accela UPLC. I am also interested in using this powerful instrumentation to conduct proteomic, metabolomic and other biochemical research. Although I focus on using mass spectrometry methods, I am open to using any and all technologies that can result in novel insights into an interesting question or problem.Karen Ho, B.Sc., M.Sc. - Senior Laboratory Instructor
Research Interests: My research interest is to develop a series of lab experiments for our undergrad Chemistry labs which varies from first year to final year. In addition, I am interested in chemistry education that will enhance student learning in labs. Currently, I am working on a project that involves with the Effectiveness of Videos on Student Retention.
List of Projects: I am looking for either a volunteer or CHEM 5201/5202 student, to work on chemical education or bench chemistry.

Research Interests: Many chemical reactions that cannot be easily performed in the lab can be modeled with a computer. In other cases, a model can add in the understanding of the detailed bonding or energy of a chemical process. My current projects involve the computational study on modeling metals in liquid helium, along with side projects on modeling transition metal complexes. I am also interested in the use of technology to teach undergraduate chemistry, particularly as it relates to so-called “dry” chemistry labs.
List of Projects: I am looking to accept CHEM 5201 students for projects involving chemical education or chemical modeling. Knowledge of quantum mechanics is not required; a hard worker who is willing to learn is what I am looking for.

Brett McCollum, PhD - Professor
Research Interests: My research interests focus on chemical education, specifically (1) effective uses of technology for the teaching and learning of chemistry and related fields, and (2) the benefits and challenges of interdisciplinary teaching. I also have extensive experience with identifying chemical reaction mechanisms through the use of muonium (as a radioactive probe of chemical reactivity) and molecular modeling software.
List of Projects: I am currently looking for undergraduate research assistants for a project measuring the impact of iPads on students’ learning of molecular geometries and properties. Paid, volunteer, and course credit options are available. Additionally, students with a wider interest in chemical education should contact me regarding possibilities for a CHEM 5201 project. You can email me at email@example.com .

Susan Morante, B.Sc., M.Sc. - Associate ProfessorBumblebees are notoriously difficult to identify from morphology alone. This has led to the development of more accurate techniques for species identification, including DNA analysis and mapping of the wing venation. The original scope of my research was to use chemical extraction to identify the pigments present in various colours of bee hair as a means of identifying different species. We then found that Raman spectroscopy provided a fast and non-destructive identification method to confirm the types of pigments present in hairs from Bombus moderatus, B. nevadensis, and B. rufocinctus. However this was quickly ruled out as a means of separating the various species, as the natural variation, even within a single hair, was too great for accurate identification. However, interesting observations of the hairs fluorescing under a light microscope led to the investigation of the cause of the fluorescence, including Raman spectroscopy, confocal microscopy, scanning electron microscopy, and chemical extraction. Although the main pigment present in bumblebee hairs is melanin, the cause of the fluorescence is still under investigation.
