Mentors: Jane Hill, PhD and James O'Malley, PhD

Education: University of Guelph - Applied Mathematics and Statistics with a Co-op Option, Certificate in Business, University of Guelph - MSc Applied Mathematics

While studying applied mathematics and statistics at the University of Guelph, I quickly realized that mathematical thinking provides important insight in a variety of disciplines, but particularly in the realm of biomedical science. Ever since I've been passionate about data-driven approaches to research in human health, particularly in the realm of infectious disease. When I'm not thinking about science (do we ever really stop thinking about science?) you can usually find me hanging out with my dog, throwing spontaneous dinner parties, or dragging my peers out to various different adventures throughout the New England area.

Mentor: Michael Whitfield

Education: University of California Irvine - Biology

My research interests include genomics, biostatistics, rare diseases, and the human microbiome- interests that I have combined in my work with Dr. Michael Whitfield. The Whitfield lab studies Scleroderma, a rare autoimmune disease characterized by fibrosis and heightened immune response in various organ systems of the body. In his lab, I am currently exploring the potential associations of the epithelial microbiome with the host immune response presented in patients with Scleroderma (SSc). This is part of an investigative effort to elucidate the potential environmentally-driven etiology of SSc. As a 2016-2017 Burroughs Wellcome Scholar, I was given the opportunity to explore the possibility of a hybrid PhD, one that includes laboratory science and data science training. These opportunities only became available to me through the encouragement of cross-training in the multidisciplinary space that QBS offers. Outside of school, I can be found socializing with friends or exploring the New England area.

Education: Smith College - Biochemistry and Neuroscience

My research interests are cancer immuno-genomics. The Amos lab in genomic medicine was a perfect fit for me given my interests in genomics. Dr. Amos and my co-mentor Dr. Robert Frost have been excellent mentors. Working in the Amos lab, I was able to mesh my biochemistry and medical background to design a project focused on the application of immunotherapy in various types of cancer. Specifically, I am examining the interaction of immune cells in the tumor microenvironment with neoplastic cells using sequencing data and determining the impact of immune cells on driving cancer pathophysiology�specifically identifying unique immune signatures indicative of metastasis. In the Amos lab, I am able to collaborate with clinicians, immunologists, surgeons, and bioinformaticians, and am challenged to use a variety of tools to tackle key questions in cancer immunology.

My main research interest is integrating epigenetic (DNA methylation) and proteo-genomic data sets for cancer subgroup identification and downstream characterization using machine learning and statistical approaches. My most recent research projects are related to identifying somatic alteration biomarkers in homologous recombination DNA repair-deficient cancers. My ongoing work includes profiling DNA methylation and proteomics in triple negative breast cancer and integrating multiple tumor molecular profiles for predictive analytics. Through the Burroughs-Wellcome Big Data in Life Sciences training program, I also had the opportunity of collecting primary data from patient tumor and cell line biospecimens for subsequent data analytics.

Craig MacKenzie, BS, MS

Mentor: Gevorg Grigoryan, PhD

Education: University of New Hampshire Durham - Mathematics • University of Illinois - MS Mathematics

My research involves mining massive amounts existing data on proteins for the purpose of computationally designing novel proteins. More specifically, we have determined a small set of structural motifs capable of describing almost all structural interactions found in proteins (with known structures). We are now using sequence-structure relationships from these motifs to design novel proteins. Beyond this I'm interested in computationally designing proteins (and other molecules) for use in synthetic biology, nanomaterials and therapeutics. I have a bachelor's degree in Mathematics from the University of New Hampshire. The interesting and diverse research conducted by QBS faculty drew me to the program which I joined in 2012. When I joined the program I did not plan on working in the field of protein design, but got hooked after doing rotations in the labs of Chris Bailey-Kellogg and Gevorg Grigoryan my first year.
