I went to the Clarion library database and did a search on articles by john Dabiri in the Academic Search Complete database. There are quite a few interesting articles written and co-written by him. I found the one on, "The 'upstream wake' of swimming and flying animals and its correlation with propulsive efficiency, particularly interesting. He co-wrote it with Jifeng Peng, one of his graduate students. If you want to read one of the many interesting articles he wrote take a look at the Clarion databases.
