Is it possible to Reduce/Correct Bias through EM algorithm?

I am dealing with few overdispersed count models and using mixed Poisson distributions to deal with overdispsered data. I've used MLE technique to estimate the paramters, however ML estimates are lower biased. I am trying to correct the bias using advanced technquies. I have started to read about few "bias correction" techniques and hope to apply them in later.

My question is, Does Expectation–maximization algorithm correct the bias? What's the use of EM algorithm in general?

Thank you.
