I am interested in a part-time or short-term undergraduate research assistantship

Summer Research Experience for Undergraduates (REU) 

Undergraduates apply to the Harvard SEAS REU Program and indicate interest in several choices among a large number of positions. I usually post one or more positions each year.

Other research opportunities for Harvard College students 

Harvard College undergraduates obtain support for summer or term-time research under the supervision of a faculty member such as myself under any of several programs, including

Harvard U. Center for the Environment Undergrad Summer Research Fund (Summer); 

Harvard College Program for Research in Science and Engineering (Summer); 

Harvard College Research Program (Summer or term-time)  

Research Experience for Course Credit

Of course there are non-job opportunities for guided research for course credit. Many departments offer a course such as Engineering Sciences 91r for students enrolled in Harvard College and I would be happy to discuss such opportunities with you before or at the beginning of the semester.
