The IBS Discrete Mathematics Group welcomes Dr. Yaobin Chen and Dr. Simón Piga, new research fellows at the IBS Extremal Combinatorics and Probability Group, starting July 1, 2026.
Yaobin Chen received his Ph.D. from Fudan University under the supervision of Prof. Hehui Wu. He is interested in extremal graph theory and combinatorics.
Simón Piga received his Ph.D. from the University of Hamburg under the supervision of Prof. Mathias Schacht. Until recently, he was a postdoctoral researcher at the Czech Academy of Sciences. He is interested in extremal and probabilistic combinatorics.
