I had been accepted at University of Iowa & LSU , Baton rogue . I am an international student and never had a chance to visit any of this university. My interests are in biological chemistry/ chemical biology / Medicinal Chemistry . I think university of Iowa has a strong program and my research interests overlaps quite nicely with few labs. University of iowa is offering around 18,000$ as TA and LSU is offering 22,500 $ as TA. I would like to have your suggestions and throw some light on making a choice, I am getting more inclines towards U of Iowa.
