Regrettably, Jadzia did not survive, and while Ezri Dax likely had many of those scientific skills to draw on, her difficulties in adjustment and the demands of circumstance kept her from displaying them much in the episodes.
Agreed. Though I did enjoy the "Seige of Ar-558" where Ezri calls upon Jadzia and Tobin's memory to deal with mines. And that Sisko assigned her to that Sisko because she was still Dax.
The other episode (Field of Fire) went overboard though.
