Sean Rasmussen
S. Rasmussen

I completed my BSc in psychology at Mount Allison University before joining the MD/PhD program at McMaster. Under the supervision of Dr. Michael Mazurek, I am investigating strategies to predict long-term treatment outcomes in response to antipsychotic medications. Recent evidence suggests that poor response to antipsychotic drugs can be predicted within the first 1-2 weeks of treatment. If physicians can identify non-responders early in treatment, then these patients could be quickly switched to another antipsychotic, minimizing the time that they are treated with ineffective medications. For this work, I have been awarded a CIHR Master’s Award and an Ontario Mental Health Foundation Studentship

Derek Chan

Derek ChanHaving just completed my undergraduate degree at McMaster, I am returning again to begin my MD/PhD studies in September 2012, conducting research in hematopoietic and leukemic stem cell biology under the supervision of Dr. Kristin Hope in the Stem Cell and Cancer Research Institute. My primary research aims are to dually investigate the molecular regulation of HSC self-renewal and identify processes that lead to leukemia transformation and progression in order to find novel treatments for such hematopoietic malignancies. In addition to conducting basic science research, my interests also broadly span the fields of paediatric oncology, global health and medical humanities.

Branavan Manoranjan

B. ManoranjanMy longstanding interest in brain tumour research stems from a high school co-operative education placement during which I explored factors that contributed to the neurosurgical management and quality-of-life of brain tumour patients. Throughout my undergraduate career in McMaster University's Bachelor of Health Sciences (Honours) program I had the opportunity to expand my research interests from a clinical to basic science model by studying the role of aberrantly activated developmental signaling pathways in brain tumorigenesis. I am now excited to pursue the next stage of my training through the MD/PhD program, and thereby bridge the internationally-renowned clinical training at the Michael G. DeGroote School of Medicine with the high-impact, novel research conducted at the McMaster Stem Cell & Cancer Research Institute.

As brain tumours represent the leading cause of childhood cancer mortality, my current doctoral work in Dr. Sheila Singh's laboratory is focused on medulloblastoma (MB), the most frequent malignant pediatric brain tumour. The identification of cancer stem cells, termed brain tumour-initiating cells (BTICs), in MB has provided novel cellular targets for the study of developmental signaling pathways. My project is interested in elucidating the role of these pathways in MB BTICs. I have been fortunate enough to be awarded a CIHR Vanier Canada Graduate Scholarship for carrying out this research. My future ambition is to merge clinical and research interests in neurosurgery and neuro-oncology, respectively, through collaborative initiatives with all those involved in the treatment and care of pediatric and adult brain tumour patients as a way to bridge the gap between the laboratory bench, patient bedside, and society as a whole. In addition to conducting basic science research, my interests also relate to quality-of-life in neurosurgical patients, evidence-based neurosurgery, and surgical innovations for resource-limited regions.

Siddharth Nath
S Nath

I completed my undergraduate studies in the Honours Biochemistry program at McMaster University in June 2013 and joined the MD/PhD program in September 2013. Under the expert supervision of Dr. Ray Truant in the Department of Biochemistry and Biomedical Sciences, my research is focused on investigating the basic cellular biology and biochemistry underlying genetic neurodegenerative disorders such as Huntington’s disease and the spinocerebellar ataxias. Understanding how these devastating disorders manifest at the cellular and molecular level may ultimately lead to the development of better therapies, while providing insight into basic cellular processes relevant to a wide array of other human diseases. My work has been generously funded through awards from the Canadian Institutes of Health Research, the Huntington Society of Canada, and various institutional scholarships.

Randa Stringer

Randa StringerI completed my undergraduate degree studying genetics and biological anthropology at the University of Western Ontario in 2013.  During that time my research focused primarily on the epigenetics of fetal alcohol spectrum disorders (FASD), with a summer spent studying dyslipidemias.
In the fall of 2013 I entered the MD/PhD program here at McMaster University, where I have continued my research in epigenetics.  Under the supervision of Dr. Guillaume Paré and Dr. Sonia Anand I am using genetic data from several large birth cohorts to investigate the effects of maternal exposures, particularly dietary patterns, on the epigenome of the offspring.  In utero exposures such as these can have profound implications on the long-term health of the child, including his/her predisposition to chronic conditions in later life like cardiovascular disease and diabetes.  By working to elucidate the role of epigenetics in programming these changes, we hope to gain a better understanding of
the interaction between fetal genetics and the maternal environment, and provide better guidelines for maternal nutrition during pregnancy.

Alexander Oberc

A. ObercI started my MD at McMaster in September 2013 and I transferred into the MD/PhD program the following year. I previously graduated with an Honors BMSc at Western University in 2013. I am currently working in the lab of Dr. Brian Coombes studying the relationship between gut microorganisms and Crohn's disease. Crohn's disease is an immune-mediated intestinal illness and Canada has one of the highest rates of Crohn's in the world. The pathophysiology of Crohn's disease is currently not well understood. My research focuses on one particular bacteria associated with ileal Crohn's disease known as adherent-invasive E. coli. I am investigating how this bacterium interacts with other known genetic and environmental risk factors for Crohn's. I've been awarded the CGS-Master's award to support my research. I am clinically interested in inflammatory bowel disease as well as infectious diseases.

Aadil Bharwani

A. BharwaniUpon completing my Honours B.Sc. in Biology & Psychology at McMaster, I entered the MD/PhD stream in 2015. Under the tutelage of Dr. John Bienenstock and Dr. Paul Forsythe, I am investigating the functional relationship between the intestinal microbiome and stress-induced changes in brain and behaviour. There is a body of work demonstrating the systemic role of the microbial community in influencing neural development and function. My project endeavours to assess the effect of modulating the composition and function of the gut microbiota on stress-induced disruptions, and unravel the mechanistic pathways—such as the vagus and immune system—that underlie this relationship.

Madelaine Leung

M. LeungI graduated from Queen’s University in 2014 with a BScH in Biochemistry, and started an MSc in Chemical Biology at McMaster University.  The following year I transferred into the MD/PhD program.  My research is in medicinal chemistry and drug discovery, under Dr. Fred Capretta.  I am focusing on the synthesis of chemical libraries, with the purpose of discovering and developing inhibitors of aminoglycoside nucleotidyltransferases and other aminoglycoside modifying enzymes.  As aminoglycoside modifying enzymes are a key mechanism of bacterial resistance, inhibition of these enzymes should rescue the activity of obsolete drugs, allowing them to be effective again.


Derek Chu

Derek ChuAfter completing my BHSc at McMaster in 2008, I joined the MD/PhD program to study mechanisms of allergic sensitization to food, particularly to peanut under the superperb mentorship of Dr. Manel Jordana. Peanut allergy affects ~1-2% of the North American population and is a severe food hypersensitivity in that, unlike many others, it is highly associated with anaphylaxis and typically not outgrown. My projects have taken me to work on how epithelia instruct for Th2 responses in in house-dust mite-induced allergic asthma and peanut allergy, for which I've been fortunate enough to be awarded a Vanier doctoral award from CIHR. Clinically, I have an interest in diseases involving the immune system, and look forward to my clerkship experience. I am actively involved in immunology curriculum development for the MD program.

I graduated from the Honours BSc Biology program at St. Francis Xavier University in 2005. I entered the Master of Science medical sciences program at McMaster later that fall, transferred one year later to the PhD program and again a year later to the newly formed MD/PhD program at McMaster University. I am presently enrolled in year 6 of the MD/PhD program and have just recently completed my PhD thesis entitled: “Regulation of brain serotonergic and dopaminergic neurons: the modulatory effects of selective serotonin reuptake inhibitors, atypical neuroleptics and environmental enrichment.” Though I am continuing to publish my work, I have re-entered medical clerkship and will graduate with both degrees in May, 2012.
