First of all I will take "involved in research" to pretty much mean waffling around in grad school before finding your way to industry and making the Big Bucks. Then I would say learn another language if you like learning languages. Or if you plan on ordering a bride from oversees or something. I work as a computer engineer for a large tech company with global reach and I see no reason to know anything other than English. Sure, learning things is nice but as far as what increases your marketability or productivity, you're better off spending your time elsewhere. These are the languages you should know as a computer engineer, at least if you're doing chip design:

• English
• Tcl
• Perl
• Verilog

In no particular order.
