    Mini-symposium for young investigators in memory of Dr. Robert Marquis to be held March 10, 2015

    Robert Marquis Mini-Symposium for Young Investigators

    Hynes Convention Center, Boston, MA

    About Robert Marquis

    Dr. Robert Marquis

    Dr. Robert E. Marquis, PhD, was chair of the Department of Microbiology and Immunology at the University of Rochester School of Medicine and Dentistry, and a beloved teacher to many students who trained at the medical school and at the university’s College of Arts and Sciences. He died in January 2014 at the age of 80. Originally from Ontario, Canada, “Bob” earned his M.S. and PhD degrees from the University of Michigan in Ann Arbor. He spent two years as a post-doctoral fellow at the University of Edinburgh in Scotland, where he studied under the guise of Peter Mitchell, a British biochemist who was awarded the 1978 Nobel Prize in Chemistry.

    Bob began his career at the University of Rochester in 1963 as a senior instructor in Microbiology and was continuously funded by the National Institutes of Health until his retirement as a professor in 2012. During his early years at the medical school, he studied energy transduction – how cells and bacteria develop energy from food. From the 1970s until the end of his career he focused on oral streptococci, a type of bacteria present in the mouth that are major contributors to tooth decay. He had a secondary appointment in the Center for Oral Biology and his work on the effects of fluoride on cavity-producing bacteria earned him international recognition and the 2006 Distinguished Scientist Award for Research in Dental Caries from the International Association for Dental Research.

    As passionate as Bob was about his research, he was equally, if not more passionate about the colleagues, trainees, and students he worked with every day. He influenced the lives of many graduate students who considered him to be a remarkable colleague, mentor and friend. It is not surprising then that many of Bob’s graduate students went on to assume distinguished careers in academia, industry, or public health service.

    Bob's influence also included undergraduate students on the University of Rochester’s River Campus, where he was a founding director of the Undergraduate Program in Biology and Medicine. This program combines the College of Arts and Sciences and the School of Medicine and Dentistry to provide courses for undergraduate students with lectures, laboratory work, specialty seminars and research experiences. Bob helped start the program in the early 1980’s and it led to the creation of the Bachelor’s of Science degrees in Biological Sciences, which includes tracks in Biochemistry, Cell and Developmental Biology, Ecology and Evolutionary Biology, Microbiology, Molecular Genetics, and Neuroscience. Thanks to Bob’s work, the program is a major conduit for undergraduate students into research labs at the medical school.

    Outside of the University, Bob loved the Rochester Philharmonic Orchestra and was a huge fan of theater, traveling annually to the Shaw Festival in Niagara-on-the-Lake and the Shakespeare Festival in Stratford, Ontario. He was also known to fly to London with his wife on a regular basis to catch plays in London’s West End. Another hobby was custom brewing, an art that he shared and passed on to many.

    Purpose

    This mini-symposium honors the memory of the late Robert E. Marquis and the knowledge he eagerly shared with students, trainees and early career faculty members. Its main objective is to promote information exchange among scientists who engage in oral microbiology and immunology research and clinical studies pertaining to oral health and disease, and to provide a forum through which new investigators entering the field can network with established investigators and so create contacts that can help nurture their research progress and productivity.

    UR Tests HIV Vaccine Pill

    Researchers at the University of Rochester Medical Center are testing a new oral vaccine to prevent infection with HIV, the virus that causes AIDS. The vaccine is unique because it is given as a pill, unlike most HIV vaccines tested to date that have been given as shots

    The study is funded and designed by Beth Israel Deaconess Medical Center (BIDMC), which received support for a Collaboration for AIDS Vaccine Discovery grant from the Bill & Melinda Gates Foundation. The URMC team and BIDMC are collaborating with the International AIDS Vaccine Initiative, which is helping to organize the study through its Vaccine Product Development Center to provide services to BIDMC grantees. This is one of the first studies to benefit from this partnership and URMC is the only center in the world testing this vaccine.

    New Study Probes Link Between HIV Drugs and Vascular Disease

    A new $3.8 million grant will bring together clinical and bench researchers to better understand why individuals who receive anti-retroviral treatment for HIV are at greater risk for heart disease and stroke.

    The good news is that the drugs being used to fight HIV are increasing life expectancy to normal levels, said University of Rochester neurologist Giovanni Schifitto, M.D., one of the co-leaders of the study. However, one of the long-term complications is that these treatments, the infection itself, or a combination of the two are increasing risk for cardiovascular and cerebrovascular disease in this population.
