DESCRIPTION:The use of magnetic-field-induced Feshbach resonances between 
 collisions of ultracold atoms has revolutionized the field of quantum dege
 nerate gases\, permitting both the exquisite control of the atomic interac
 tions and the coupling of free atoms into weakly bound molecular states. I
 n two different Bose-Einstein condensation experiments\, we explore these 
 complementary avenues of research. The first experiment uses a quantum deg
 enerate mixture of Rb and Cs with the goal of creating ultracold heteronuc
 lear molecules. The second experiment focuses on the formation of bright m
 atter wave solitons using a condensate with attractive interactions and ai
 ms to use such solitons to probe the weak forces between an atom and a sur
 face. This talk will give an overview of both of these projects highlighti
 ng our recent results.\n\n
