Quick help transliterating name

[bigtops]

Well, this might look like an easy question but sitting with my handy-dandy Oxford dictionary and then a belabored trip to Zhongwen.com, I still am not confident I've got the pinyin for this name correctly. I've got Shu4 fu4 shi4 lu2 but Something's telling me that isn't it.

Many thanks!

My guess would be lai4 shi4 zuo4, although that assumes that the second stroke in the right half of the first character is missing and that they are traditional form.

赖世伦 - seems to be the name of a doctor or medical researcher. You have the surname in tradition, I've typed it in simplified.

Lord have mercy, that's gotta be it. Maaaaaaaaaan, thank you both. I've been having a heck of a time trying to track this guy down.

A further question... Perhaps I am going blind but while I figured that first character was a single hanzi and not two side by side, I could not figure out what the radical was in the dictionary. Did I make a mistake or overlook something? I was using both Zhongwen.com and a concise Oxford dictionary, looking up by radical.
