The name Jean Piaget appears a lot in bibliographies of this subject. See http://en.wikipedia.org/wiki/List_of_publications_in_psychology#Developmental_psychology
for more information
It would help if you would designate more specifically the area(s) of developmental psychology that interested you. I searched Google under the key words "'recent research' 'developmental psychology'" to get these possible sources:

http://eci.uchicago.edu/faculty/B_Bertenthal.html
http://www.developmentalpsychologyarena.com/books/Infant-Development-isbn9780863774638

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps a little more. Thanks for asking.
