Biography

Xiuyun Tian received her PhD degree in Biochemistry and Molecular Microbiology under the supervision of Dr. Keqian Yang from the Institute of Microbiology, Chinese Academy of Sciences (CAS). During her Ph.D. years, she mainly focused on the biological significance of the interaction between physiologically active small molecules and regulatory proteins. She also applied structural biology and biochemistry to rationally mutagenize enzymes of commercial significance. As a Ph.D. candidate, she was awarded Director Scholarship of IMCAS, “Procter & Gamble” Scholarship and Graduate University of CAS Excellent Students Awards. Now she is working on the communication between nucleus and mitochondrion during development and differentiation in Cryptococcus neoformans.
