Cottrell Lectureship Seminar with Prof. Shahir Rizk, Indiana University, School of Medicine
Biosensor Design and the Power of Stories in Science Communication
The Department of Chemistry is pleased to present Prof. Shahir Rizk, a Cottrell Lectureship Seminar
The recent progress in protein structure determination has led to a revolution in the field of protein engineering. In my lab, we use protein engineering strategies to develop biosensors for an array of small molecules. Our central components are engineered protein receptors that produce a change in fluorescence upon binding to a ligand of interest. We show that multiple receptors can be combined to function in parallel to simultaneously detect the presence of several analytes in a complex environment such as bacterial cultures. We also expand the utility of our engineered proteins by developing low-cost miniature fluorescence devices for field-deployable applications.
We also believe that science is not done until it is communicated. This is why my work emphasizes the use of art and storytelling to train scientists on how to become more effective communicators, especially in the face of misinformation. By bridging protein engineering with science communication, my work highlights how innovation in the laboratory and thoughtful storytelling can work together to expand both the reach and the impact of science.
BIO
Shahir Rizk is an associate professor of chemistry and biochemistry at Indiana University South Bend and the IU School of Medicine. His research uses protein engineering to develop biosensors for detection of pollutants, and pathogens, and to monitor bacterial communication in culture. Shahir is a writer, artist, and science communicator. He is the co-author of the award-winning popular science book: “The color of north: the molecular language of proteins and the future of life” (Harvard University Press). He is also the co-host of the Rust Belt Science podcast.
Please note that while most of our seminars are on Friday, this seminar will be on Thursday.
Cottrell Lectureship is supported by the Research Corporation for Science Advancement. RCSA is America’s first foundation devoted solely to the advancement of science, founded in 1912 by Federick Gardner Cottrell.
