in your setting its not possible
its known commonly as link aggregation or Port Bonding, Port Teaming, LACP (Link Aggregation Control Protocol) or IEEE 802.1ax and IEEE 802.3ad -
http://en.wikipedia.org/wiki/Link_aggregation
it cannot support wifi and lan only multiple lan interfaces and the switch at the other end needs to support it and be configured for it on your ports
i cant remember if windows supports Port Bonding or not but i do no that Linux and Mac OS support port bonding
if your not restricted to what device can connect to the wifi and lan what you could do is purchase a small format computer that can accept wireless usb adaptors and install a firewall/routing OS such as PFSense
which can do "Multi-WAN routing" this will allow you to balance load over both connections which gives you extra capacity and failover should one connection fail. on the internal side you could just plugin via lan or attach the internal side to a wireless access point for wifi access
however it should be considered not a full solution because a single download connection will not be able to use more than one of the connections simultaneously (unless you use a download manager that makes multiple connections to speed up transfers)
you could set this up as a VM on your current computer but your network configuration would get pretty messy if you move about a lot with that computer (eg laptop) so it may not be worth the effort of doing that
i should point out that you really should read your universities IT policy before you do this - they may have restrictions that make this thing not allowed and they may also throttle traffic from single users anyway and thus you will not actually get any speed increase
