I would be really surprised if Hopkins didn't participate in the commuter incentive program through MDOT. Here's the general webpage on MDOT's website: Commuter Choice Maryland

Also, here's more literature in PDF form, but it's a bit old (2019), if you find out they don't participate and want to advocate for them to do it. https://www.mdot.maryland.gov/OPCP/MDOT%20Employer%20Benefits%20Toolkit.pdf
