There, she was given access to documentation on an agent of Soviet-backed toxin warfare known as "yellow rain", which ultimately became the subject of her doctoral dissertation carried out under the mentorship of Burton Singer.

[1] Her thesis, entitled Yellow rain revisited: Lessons learned for the investigation of chemical and biological weapons allegations evaluated yellow rain as a case study in chemical and biological weapons allegations, as well as for evaluating the protocols used to mitigate proliferation of such warfare.
