“I collaborated with Marie on four different research projects over the last several years. She has a scientific mind, excellent familiarity with the literature and research process, and develops clinically-relevant and directly applicable proposals. Her dedication to project completion is admirable, as is her ability to mediate the often challenging dynamic of group work. She is readily able to identify and secure the resources required to address research hypotheses. I hope to be able to collaborate with her again someday in the future!”

“Marie assisted us with an experimental procedure that was new to our laboratory, which focuses on canine and feline nutrition. She played an instrumental role in protocol development and approval and the implementation of procedures, training of lab personnel, and care of our canine patients during our recent pilot study.  Marie is not only highly skilled and knowledgeable, but she is a very organized and personable clinical researcher.”
