Yu, Seok-Ho

Staff Scientist

Yu, Seok-Ho

Dr. Yu joined Greenwood Genetic Center’s Division of Research in August 2018. His research is focused on the development and application of chemical biology technologies that are used to label and track glycoproteins in cells and tissues. This work is uncovering new molecular mechanisms underlying several genetic disorders. Before he joined Greenwood Genetic Center, he held the position of Assistant Research Scientist (non-tenure track faculty member) at the Complex Carbohydrate Research Center in University Georgia. Dr. Yu leverages his broad skills in biochemistry and chemistry towards the investigation of lysosomal storage disorders and CDGs, and other disorders of interest at GGC.

Meet Jeremiah

Play peek-a-boo with 9 month-old Jeremiah Licorish of Florence, and you'll be rewarded with a huge grin that lights up both his and his mother's faces. But this family has been through the unthinkable over the past few months, with very few reasons to smile. At first things were going well. Jeremiah was a happy, healthy newborn, doted on by his mother, Aneesa, and his three big brothers. But when Jeremiah was around 5 months old, Aneesa noticed ...
