Meghan Foster assists college faculty with all travel reimbursements.
She asks you to use the travel reimbursement information page (TRIP) form (pdf) to decrease the number of emails that you have to exchange to get your reimbursement processed. The TRIP form was designed to be all electronic, eliminating the use of campus mail and/or the need to walk to her office.
Please provide the form, along with scanned copies of your travel receipts, to her via email for processing of your reimbursements.
Of course, if you enjoy the walk to Milam, she always accept visitors :-)
Oregon State University has a comprehensive list of travel resources such as travel rates, policies, references and what to do once you get back.
