In the Philo of Alexandria Seminar of the Nov. 1995 annual meeting of Society of Biblical Literature Katie Evans had a paper on Alexander the Alabarch; Roman and Jew. The full text of the paper was later published in SBL Seminar Papers, 1995, p. 576-594.

However, she also made a webpage on Alexander; this has now been moved as a subpage to her homepage. See also here. She also states that she plans a page on Philo of Alexandria, on Alexanders Egypt, and on Alexanders Palestine. But so far, none of these are avialable.

So still, you have to direct you browser here, to find more info about Philo. :-)
