Biography: 

Sridhar Hannenhalli is a professor in the Department of Cell Biology and Molecular Genetics and holds joint appointments in the Center for Bioinformatics and Computational Biology (CBCB) and UMIACS. He also holds an affiliate position in the university's Department of Computer Science and the Department of Genetics at the University of Pennsylvania.

Hannenhalli served as the interim director of CBCB in 2013. He has previously held research positions at GlaxoSmithKline, Celera Genomics, and as assistant and then associate professor in the Department of Genetics at the University of Pennsylvania.

Hannenhalli's current research focuses on comparative genomics, transcriptional regulation, and evolution.

He has served on program committee for numerous bioinformatics conferences and chaired Workshop on Algorithms in Bioinformatics (WABI) and Research in Computational Molecular Biology (RECOMB) conferences. Hannenhalli has also served on several national and international grant review panels and as academic editor for PLOS ONE and BMC Genomics. He has co-authored more than 75 papers in computer science and bioinformatics.

Hannenhalli received his doctorate in computer science from Pennsylvania State University in 1996, where he developed combinatorial algorithms for genome rearrangement problems.
