Jin is a former Graduate student and Post-doc of Bob's, rejoining us for his sabbatical year from his Faculty position at Seoul National University in Korea. Here, Jin is pictured with a Biorad protein purifyer from 1852. It was discovered in the cold room in Koshland Hall, and Jin has resurrected it to full working order, cleaning many layers of cold-tolerant fungus from its many surfaces. Welcome back Jin, we are very happy to have you.
