Past members of Dave Rogers' group in the Carleton Laboratory for Radiotherapy Physics
Lesley
Buckley, Ph.D. 2005 Lesley graduated with a Ph.D. in July 2005. Her research
involved the use of Monte Carlo techniques to study a variety of correction
factors used in current dosimetry protocols. This included the development
of a new user-code for the EGSnrc system, CSnrc, that improves the
efficiency of certain calculations. She obtained a B.Sc. in physics from
McGill University (1999) and an M.Sc. in medical physics from the
University of Wisconsin - Madison (2001). After a residency at the Ottawa
Hospital Regional Cancer Centre, she became a clinical medical physicist at
the same institution in Jan 2007.
Dan La Russa, Ph.D. 2009 Dan's Ph.D. investigated various
fundamentals of ion chamber dosimetry via a combination
of computational and experimental techniques. One of his
projects involved investigating problems with the use
of the standard temperature-pressure correction factor
with low-energy x-rays and one of the resulting papers
won the AAPM's Farrington Daniels award for the best
dosimetry paper of the year. His work also testing the
limits of Spencer-Attix cavity theory. He obtained a
degree in chemistry at Lakehead University in 2004. After
sumbitting his PhD thesis he entered the Physics Residency
program at the Ottawa Hospitasl Regional Cancer Clinic.
T. Palani Selvam, PDF 2004-2006 Palani was a visiting scientist from the Bhabha Atomic
Research Centre (BARC) in Mumbai, India. He was a
Postdoctoral Fellow here at Carleton from April 2004 to Mar. 2006.
His projects included
Monte Carlo modelling of the response to
the NRC 90Sr/90Y primary
beta standard using BEAMnrc/EGSnrc code system
(Development of an efficient MC model to benchmark
the experimental response)
Evaluation of various correction factors
for the primary beta standard using the above
model. This included development of a Bragg-Gray
stopping-power ratio option in the SPRRZnrc code.
Randy Taylor, MSc 2006 and Research Assistant 2006-2008 Randy completed a H.B.Sc. degree in physics in 2004 at the
University of Waterloo. During that time he worked in various
Co-op placements doing everything from navigating satellites
for Telesat in Ottawa to modelling the EM properties of MRI
head coils at Robarts Research Institute in London, ON. He
completed his M.Sc. degree in medical physics at Carleton in
2006 and continued to work for the group remotely from his
home in Waterloo until Sept 2008. His research focused
primarily on topics
related to his M.Sc. thesis, which includes Monte Carlo
simulations of brachytherapy treatments.
Rowan Thomson, PDF 2007 - 2009
After receiving her PhD in string theory from Waterloo
University while working at the Perimeter Institute,
Rowan joined the group in 2007. Her work focused on
applying the prototype BrachyDose code to applications
related to eye-plaque therapy, developing the code further and on some fundamental
dosimetry problems. In Sept 2010 she joined the Faculty
of Carleton University.
Lilie Wang PhD 2009 Lilie was a Ph.D. student whose project was to study
the ion chamber correction factors in dosimetry protocols
by Monte Carlo simulation. The research involved the
improvements of an EGSnrc user code specially developed
for the correction factor calculations. He obtained
an M.Sc. in medical physics from Laurentian University
in 2005. He took up a PDF at M D Anderson Cancer Center in
2009
Zdenko Sego, M.Sc. 2006 Zdenko obtained an M.Sc. in the medical physics
program after his thesis defence in April 2006 of his
project on the Monte Carlo modelling of medical linear
accelerators. He obtained his B.Sc. degree from the
University of Sarajevo in Yugoslavia, and worked in
Canada as a software designer in the automation and
telecommunication industries for 11 years. Currently,
he is working at Bubble Technolgy Industries in Deep River,
Ontario.
Gultekin Yegin, PDF 2004, 2005-2006 Gultekin works at Celal Bayar University in Manisa,
Turkey. He worked with the group at Carleton from Dec
2003 to March 2004, for two weeks in July 2004, and for a
one year visit that ended in September, 2006.
Collaboration with him continues. His major
research interests included
Further development of his Multi-geometry
package for the EGSnrc system
Application of this package to dose
calculations for brachytherapy treatment of
prostate cancer.
Guoming Xiong PDF 2006-2007 Guoming was a visiting research fellow in the lab. He
obtained his Ph.D degree in physics at Nanjing University
in China and worked in the area of computaional physics and
chemistry. He worked in several universities in the US and
Germany, doing simulations on the structures of proteins and
nanomaterials before working here at Carleton University. He
worked on Monte Carlo simulations and dosimetry in flattening
filter free linac beams. He is currently a PDF in Munich.
The following are Carleton University graduate students supervised by
D W O Rogers while he was at NRC, Ottawa.
