Research Interests:

The story of life on Earth is likely to be a story of cold.  The first organic molecules
and cells may have arisen on Earth in icy conditions, providing an evolutionary
“cold start” to life. As recently as 500 million years ago, all life has had to survive
through global glaciations.  Even today, Earth’s biosphere is largely cold, with as
much as 80% having an average temperature of less than 5oC.  Clearly, understanding
how organisms adapt to cold temperature is important for a variety of disciplines,
from the evolution of life to the ecology of arctic environments to cellular biology
and physiology. However, surprisingly large gaps exist in our exploration of the
biology of cold adaptation.  Most notably, investigations of cold adaptation are
nearly non-existent in fungi, one of the five classical kingdoms of life.  In addition,
the roles of sterol metabolism in cold adaptation in any organism are similarly
unexplored. Current research in my lab focuses on laying the foundations for deep
exploration of the genetics, molecular and cellular biology, and physiology of cold
adaptation in yeast, a unicellular fungus.  It is likely that results of these studies will
have relevance to other fungi, and perhaps to other kingdoms of life.

In a search for genes required for ER biogenesis in the yeast Saccharomyces
cerevisiae,
the Wright lab discovered that mutations in a subset of genes involved
in ER-associated degradation (ERAD) result in cold sensitivity.  In collaboration
with co-PI Martin Bard (IUPUI), they also discovered that these genes are required
for proper regulation of sterol metabolism. These observations lead to the foundational
hypothesis that they explore:  ERAD regulates key aspects of sterol metabolism in yeast
and this regulation is required for cold adaptation.  To test this hypothesis, they use
genetic, biochemical, and cell biological approaches to determine both the molecular
mechanisms by which ERAD regulates sterol metabolism and also whether this regulation
underlies the role of ERAD itself in cold adaptation.  To examine the ecological and
evolutionary relevance of sterol metabolism in cold adaptation, experiments in S. cerevisiae
will be coordinated with analyses of sterols in psychrophilic yeast species isolated in
Antarctic environments.  In addition, the genes in S. cerevisiae that are necessary for
cold adaptation have been identified using global genetic screens and are being analyzed
using genomics approaches.  The results of these studies will provide specific insights into
the role of sterol metabolism and ERAD in cold adaptation, as well as create a framework
for long-term investigations of cold adaptation in yeast. 


Education Interests


At the core, I see myself as both a teacher and a researcher.  Consistent with this vision, undergraduate education is inextricably woven into essentially all of my activities.  For example, all of my research has involved undergraduates, some of whom presented their work national meetings and/or co-authored research papers.  In addition, I spend considerable effort on activities that promote innovation and improvement of undergraduate education.  Based on experiences in the classroom, national discussions, and workshops, what I do in the classroom has been transformed over the years from a traditional teacher-centered model of “lecture-and-test” to a learner-centered model that promotes building of life-long skills.  This transformation has been accompanied by the realization that sharing teaching innovations and solutions is important.  As a result, I have participated in a variety of workshops and seminars and published several papers that deal with teaching issues.  Students interested in gaining significant teaching experiences and learning how to effectively integrate teaching and research would be very welcome in my lab.
