Here's one link:

http://www.thyroid%2Dinfo.com/articles/soydangers.htm

If you read down you'll see it mentions the research of Dr. Mike Fitzpatrick, an environmental scientist and phytoestrogen researcher who has conducted in-depth studies on soy.

"Dr. Fitzpatrick makes it clear that soy products can have a detrminental affect on both adults and infants. In particular, he firmly believe that soy formula manufacturers should remove the isoflavones -- that part of the soy products that act as anti-thyroid agents -- from their products."

Furthermore:

"Researchers have identified that the isoflavones act as potent anti-thyroid agents, and are capable of suppressing thyroid function, and causing or worsening hypothyroidism. Soy is a phytoestrogen, and therefore acts in the body much like a hormone, so it's no surprise that it interacts with the delicate balance of the thyroid's hormonal systems. High consumption of soy products are also proven to cause goiter, (Anti-thyroid isoflavones from soybean: isolation, characterization, and mechanisms of action, Divi RL; Chang HC; Doerge DR, National Center for Toxicological Research, Jefferson, AR 72079, USA, Biochem Pharmacol, 1997 Nov, 54:10, 1087-96)"

Another good research is the Soy Online Service:

It has links to studies as well.
