Our research group specializes in environmental fluid mechanics research, with specific interests in coastal processes, wave mechanics, stratified flows, and turbulent mixing.  A full publication list, with pdf downloads, is available as part of my c.v.  Summaries of several active lines of research are provided below.  Questions, requests for data, or consulting inquiries should be directed to dfh4 @ psu . edu.
