Eric Johnson-Chavarria was named a finalist in the School of Chemical Sciences’ (SCS) 2012 Science Image Challenge. The Challenge is designed to recognize computer-assisted or traditional scientific images that inform, educate, and inspire.
“The judging panel was very impressed by all images submitted by SCS undergraduate, graduate, and postdoctoral researchers for this year’s Challenge, but Johnson-Chavarria’s image stood out for its visual impact, communication, and originality,” said SCS Director Jonathan Sweedler.
Johnson-Chavarria’s image is a single cell trapping and analysis of Escherichia coli in a free solution using a novel hydrodynamic trap. The trapping (bottom panel) occurs in phase contrast (left panel) and fluorescence (right panel) is observed induced by on-demand nutrient exchange.
Johnson-Chavarria received his Bachelor of Science in Physics from the University of Texas at San Antonio. He is a graduate student in Professor Charles Schroder’s group where he is working to develop a novel microfluidic device for single cell manipulation and sorting.
