Prof. Grant Allen

  • Bioprocessing engieering for:
  • waste water treatment;
  • maximization fo value from industrial waste streams;
  • and microalgae production from waste CO2 and waste water.
Dr. Allen’s research focuses on the interdisciplinary field of bioprocess engineering, with particular application to the treatment of aqueous and gaseous emissions and the utilization of wastes for energy and chemical production. This work often involves collaborations among engineers, microbiologists, biologists, and chemists. One of his main areas of activity is in biological wastewater treatment, particularly as it relates to the pulp and paper industry. Much of his earlier work was on understanding and optimizing the biological treatment of chlorinated organic compounds and other bioactive compounds from kraft pulp mills, as well as understanding and managing the impact of process disturbances (e.g. temperature, feed, oxygen) on treatment systems. Dr. Allen’s group’s more recent work has been on biologically producing value-added products (e.g. energy, biopolymers) from wastes, such as converting wastewater biomass into adhesives and biosurfactants, and enhancing biosludge dewatering. He has also researches the development of biofilm photobioreactors and processes to grow microalgae for fuels/chemicals from waste carbon dioxide, sunlight, and wastewater. Biological treatment of waste gas streams is another area of interest, including projects on bed design, kinetics, microbiology and modeling.

Dr. Allen is a Professor in the Dept. of Chemical Engineering and Applied Chemistry and is the Chair of the Department of Chemical Engineering and Applied Chemistry. Among his many professional accomplishments, he is a Fellow of the Chemical Institute of Canada, the Engineering Institute of Canada, the Canadian Academy of Engineering, and the American Association for the Advancement of Science.

Prof. Alison McGuigan

  • Understanding cellular interactions, orientation, and growth by:
  • modeling tissue orginization and architecture;
  • and tissue engineering.
The objective of the McGuigan lab is to develop experimental systems to understand and control cellular morphogenesis tissue engineering applications.

Through tissue engineering the McGuigan lab is addressing the central question “How do cells make and coordinate architectural decisions in response to combinations of signaling cues?” Answering this question will fundamentally improve our understanding of embryo morphogenesis and other morphogenetic process such as wound healing, tissue regeneration, tissue integration, and tissue disorganization in disease. Applying this fundamental information will provide new therapeutic strategies for addressing problems in regenerative medicine such as engineering artificial tissues from stem cells, developing treatments for developmental diseases that result from incorrect tissue formation, and developing in vitro drug screening culture models to develop therapies for diseases like cancer or heart disease.

Tissue engineering seeks to develop advanced health technologies to regenerate and model normal and diseased tissues. During natural tissue assembly and regeneration processes, cells are recruited and re-organized into a specific architecture. For example, during wound healing or regeneration replacement cells, often stem cells, are recruited and re-organized into a specific arrangement to generate new tissue. The functionality of the tissue depends critically on correct incorporation and re-organization of the cells during the regenerative process. Understanding how cell re-organization (termed morphogenesis) is regulated and how it can be controlled is a central problem in tissue engineering. In contrast, in diseases, such as cancer, cells in the tissue re-organize incorrectly as the disease spreads. Understanding cell re-organization therefore could also provide a basis for identifying novel disease therapies.

Dr. McGuigan is an Assistant Professor and Director of the McGuigan Lab for Tissue Morphogenesis Engineering. Her research focuses on engineering functional artificial tissues as an important emerging strategy for treating patients who suffer from organ failure. Dr. McGuigan was awarded the Wake Forest Institute for Regenerative Medicine Young Investigator Award in 2006, and an NSERC Discovery Accelerator grant in 2009.
