I'm in college and I'm also in a profession that requires a lot of research. This means that I constantly use highlighters. After trying several different brands, I finally found the perfect highlighter.
Sharpie Liquid Highlighters truly glide across the page. They are the smoothest highlighter I have ever use. Also, these highlighters don't dry out as badly as marker-style highlighters. Plus, they come in a large variety of colors, making it easy to highlight information for different uses.
The only downsides to Sharpie Liquid Highlighters are that the liquid is used up quickly and they sometimes soak through the page, if you aren't careful. Other than those two things, these highlighters are amazing and the only brand I'll buy.
