How in the heck do I find a good postdoc?!

I am a PhD candidate in Pharmacology and Toxicology, specializing in environmental toxicology (specifically xenobiotic metabolism, disposition, and toxicokinetics). Ultimately, I would love to stay in academia, but if I needed to I want to be marketable as a research toxicologist as well. Is there some magic way to find people who take postdocs in my discipline? Or, is there something better than finding faculty who do research I am interested in and emailing them? Any info is greatly appreciated.

you can search job postings on message boards, companies and govt. agencies.

most academic post docs are obtained by cold-emailing your CV, research summary etc., networking through your PI, at your current institution or meeting professors at conferences.

make a list of papers youve liked and research areas and who does that work, talk with your current boss and email them. email about 3-4 each round. theyll say no really fast if they dont have space, money or interest. then keep going til someone responds!
you can look at their websites and see how many people they have and you can also search grant databases to see if they have active grants.
