NanoMorphosis by Marla L. Anderson

Faced with a lethal climate, a man-made plague and hostile aliens, Earth is in trouble. Daniel Walker, the sole survivor of first contact, and his supporters launch a mission to find a new world. Although prepared to face the aliens again, Daniel never anticipates that a far greater challenge will come from an embittered nanotechnologist bent on re-engineering humanity itself. When this man threatens to destroy all that Daniel holds dear, he must face his inner demons and re-evaluate the very definition of what it means to be human.
