It's probably best to use a multi-step process. Search engines can point you in the direction of papers with keywords or title words which you may be interested in. Then use those papers and look at the bibliographies of those papers.
The bibliographics references will lead you to a set of authors who publish in that field. Now search for further articles by these authors, and for their academic or work-related web-sites. Their own bibliographies on their web page may help you to find other papers and other researchers working in that field, and also lead you to conference presentations which they may have done.
The most "cutting-edge" work is going to be the work recently presented at conferences, working groups, and SIGs (special interest groups, such as the subgroups of IEEE, e.g. SIGGRAPHSIGGRAPH: special interest group in graphics, which has a yearly convention in Los Angeles). Once you've found a listing of conferences, you can look for the collection of conference proceedings or talk title, and figure out the research groups and individuals involved in working in the topics of your interest.
I hope this helps you.
