Throughout my undergraduate degree at Brock University I was actively involved in experimental research
with Dr. Maureen Reedyk. I modified a Raman spectrometer for research, created superconducting materials,
and made low temperature measurements. I found academia interesting and decided to pursue a Master's degree.
I was able to continue research as a Master's student but was also given more opportunities to teach.
Teaching physics at Brock University was the most rewarding experience in my Master's and is one of the most
rewarding experiences in my life.
Following my Master's in 2010 I began working as a data analyst for the Pressure Pipe Inspection Company (now owned
by Pure Technologies Inc.) The company uses Remote Field Eddy Current/Transformer Coupling (RFEC/TC) to determine
damages to pre-stressed concrete cylinder pipes which transport water and wastewater underground. The technology
uses the simple concept of electromagnetic induction. The pipes are produced by spinning large steel cylinders
in a centrifuge and coating the inside and outside with concrete. The concrete (which is stronger under compression
than tension) needs to be reinforced, and so the outside is wrapped with steel wires. This means the strength of the
pipe lies in a large steel coil. In RFEC/TC technology a tool which generates an alternating magnetic field is sent
through the pipe. This induces a current in the coil, the strength of which can be measured by a detector. As
wires in the pipe break, the current will decrease at the point in the pipeline where the wires are broken. The
pipe can then be repaired in order to avoid watermain explosions or leaks, which can destroy entire roadways or
buildings and cost millions of dollars to repair.
The theoretical knowledge of electromagnetism that I gained from a physics degree at Brock University
immediately set me ahead. I had a deep understanding of the concepts and was able to quickly contribute to
the team and help develop new analysis ideas and methods. Furthermore I was able to use the hands-on experience
I gained from working in the labs at Brock University to work on RFEC/TC equipment. In less than a year I was
flying all over North and Central America using the RFEC/TC equipment to inspect watermains. (Puerto Rico was the
best!)
In the end, I can't thank everyone enough for the experience at Brock University. I frequently return and talk to
the faculty. A physics degree and hands-on experience from Brock University has left me very well prepared to work
in the engineering industry. I have also gained skills as a teacher from the physics department that cannot be
found in teachers college. I hope in the future to become a secondary school physics teacher. I also gained a great
deal of insight into the research world as a Master's student. I feel much more knowledgeable about the academic
world and am confident that if I would like to purse a PhD, the Physics Department at Brock University has given
me the skills I need to sucessfully achieve this goal.
