Dr Sandra Healy PhD
|My research interests over
the past 15 years have been primarily in the field of cancer research. After completing
my PhD I moved to the UK where I studied the mechanisms regulating cell
division and the response to DNA damage in research institutes (Cancer research
UK, Clare Hall laboratories) and universities (Cambridge University) and then
continued this work at the University of Milan, Italy. Following my postdoctoral studies I worked as
a research scientist in industry where I contributed to the development of
novel cancer chemotherapeutic agents (Pharmacia/ Pfizer/ Nerviano Medical Sciences).
In Industry I set up and ran a Microarray laboratory where we studied late stage compounds
that the company had approved for phase 1 clinical studies. I analysed the
effects of these compounds on the gene expression profile of cells to further
characterise their mechanism of action and to develop biomarkers that would
allow us to follow the activity of these compounds in clinical studies.
On returning to Ireland in 2007 I worked for two years as a research manager/scientific reviewer in Prof. Afshin Samali’s group at NUIG and contributed significantly to writing research and review articles, grant proposals and reports. More recently I am working as University Teacher which involves teaching Biochemistry to Medical students and Nursing students. I plan and coordinate the delivery of courses which involves lecturing, running practical laboratories and tutorials and coordinating staff, timetables, exams etc. At the same time I am integrated into research activities of the laboratories of both Prof. Afshin Samali and Prof. Corrado Santocanale (working on apoptosis and DNA replication) where I contribute to writing papers and reviews, participate in lab meetings and student supervision and contribute to writing grant applications.
My research activities are primarily in the field of cancer research. I am interested in understanding basic biological mechanisms related to cellular stress responses and how we can target these mechanisms to selectively kill cancer cells.
Cells are continually exposed to stress - this stress can originate from inside the cell (e.g. errors made in protein folding or errors made in replicating DNA) or it may originate from the external environment (e.g. UV irradiation, drugs or a lack of oxygen). Stressed cells initially attempt to overcome the stress and promote survival by selectively producing or activating proteins to repair the damage. However if the stress is overwhelming and cannot be repaired cells initiate the apoptotic cell death pathway. Cancer cells proliferate rapidly and hence they have a huge demand on DNA replication and protein and lipid production as well as being frequently exposed to hypoxia and nutrient starvation. To cope with these stresses cancer cells frequently activate the survival arm of the stress response while inactivating the apoptosis induction arm of the stress response by mutating key death inducing proteins.
My research is focused on understanding these stress responses and identifying proteins in the response pathways that could be targeted to selectively kill cancer cells while leaving normal cells unharmed.

| I taught Biochemistry to Medical students and Nursing students at NUIG for three years. I coordinated and taught foundation level Biochemistry courses for both 1st and 2nd year medical students and 1st year nursing students which included module design, delivery, assessment and evaluation as well as liaising with colleagues in the Schools of Medicine and of Nursing to ensure the smooth running and integration of the courses and participation in regular meetings relating to student performance, assessment, curriculum design and resource needs.
I lectured, ran practical lab classes, gave tutorials and organised grouped students projects. I am interested in using knowledge from pedagogical research on student learning and curriculum design to improve my teaching practice.
