Maybe you can have one column as 'area of specialities'. you can put all of your skills there.
Also I think in the research exprience, you can decribe what kind of work you have done / or achievement you got. That should be enough to include all of techniques you have used, at least in my field.
For research interests, my understand is to list what you want to do. I will make it match my career goal or what the job wants you to do.
But I just started to look for a job. Correct me if I am wrong. Thanks.
