Dr. Srihari Radhakrishnan

  • Former Graduate Student
I completed my Ph.D. in 2015 in the Bioinformatics and Computational Biology graduate program at Iowa State University. For my dissertation I worked in the transcriptomic and epigenetic basis of gonadal development in turtles and the consequences of sex-linkage in molecular evolution. My work was funded in part by Sigma Xi and by the National Science Foundation (MCB 1244355 and IOS 0743284) to Dr. Valenzuela.

I am now a Bioinformatics Scientist at Arc Bio, LLC.
