Finding patents filed in the name of a specific individual or an applicant/assignee may help in identifying the work being done by the applicant/assignee.
The patent databases have options for conducting inventor and assignee/applicant based search (this is where to find company information) searching:
Espacenet - Advanced Search --- Input: Applicants and Inventors
Google Patents - Advanced Search --- Input: Applicants and Inventors
From the U.S. Patent and Trademark Office, for both granted and applications files --- Input: Applicants and Inventors (in the pull-down menu)
