Doing a PhD while being unable to travel due to disability I’m starting a PhD but I’m disabled and can’t travel. This means I won’t be able to present my work at conferences. Has anyone had experience this? Will it negatively impact on my research? 

My tutor is aware but I’ve already had a sponsorship declined because I can’t travel to training courses.
(I agree that the rejection is unlawful but as I'm only just starting out I cannot risk offence.)

My intention is to publish work. I can never travel far from where I live. I'm aiming to work either in my local university or local industry. Networking and conferences just isn't possible. They would have to come to me. It's a shame because I'd love that aspect but I'm working within my limitations and trying to change my life.
Conferences can be useful, both for presenting your work but also for networking.

Some conference organisers will be willing to let you present by videoconference, if you explain the reason. Others will not want to do that - perhaps for good reasons, perhaps for really bad ones which may or may not be legal. You can also have your paper presented by a co-author, which means that you can certainly get your work included at conferences and into proceedings - but if you don't do it yourself, you don't gain much recognition.

The networking side is much harder, as you can't do that by videoconference - at least, unless you or a funder invested in a telepresence robot or similar. Not being able to network effectively is certainly a disadvantage for your future career, but should not be an insurmountable obstacle, and should certainly not prevent you from doing a PhD.

You don't mention where you live, but in many jurisdictions having a sponsorship declined because of disability (where the disability does not prevent you from studying at PhD level) might be illegal. It certainly sounds deeply unethical to me.
