张彪研究方向为组合数学,主要从事组合数学中单峰型理论和对称函数理论的研究工作。2015年6月博士毕业于南开大学,2018年8月至2019年8月到美国宾夕法尼亚大学访问。在《J.Comb.Theory Ser. A》、《Adv. Appl. Math.》、《SIAM J. Discrete Math.》、《Bull. Lond. Math. Soc.》、《Proc. Amer. Math. Soc.》等期刊发表学术论文三十余篇,主持国家自然科学基金3项、天津市自然科学基金1项。解决了John Stembridge、Francesco Brenti、Christos Athanasiadis、叶永南等人提出的多个猜想;关于实根多项式的结果被Tom Braden和Nicholas Proudfoot 在他们的国际数学家大会邀请报告中列为拟阵Kazhdan-Lusztig多项式实根性猜想的"重要证据(significant evidence)";与合作者定义的多项式被Luis Ferroni等人(Adv. Math., 2024)称为“Haglund-Zhang多项式”,并部分验证了Fields奖得主June Huh提出的拟阵增广周环Hilbert级数的实根性猜想在均匀拟阵上的情况。担任天津市数学会理事、天津市工业与应用数学学会理事、中国运筹学会图论组合分会青年理事。
