I would remodel it thus:
Recently I read an article about Jeremy England, a physicist who has his own lab at MIT and who has derived a mathematical formula that he believes explains the living things.
A relative clause tends to be perceived to be referring to the closest acceptable referent. I guess the reader will anyway percieve the second who as referring to "physicist", not directly to "Jeremy England".
Another possible way to remodel it is thus:
Recently I read an article about Jeremy England, a physicist with his own lab at MIT, who has derived a mathematical formula that he believes explains the living things.
I'm not sure if with is the best choice but my idea here it to turn the second part of the sentence into a phrase, not clause. This way, who will refer to Jeremy England, IMHO. At least in the text-based form. In an audio form, the listener might fail to "hear" the comma and so might lump the last two parts into one.
As an aside, I would also get rid of "just", it clashes a bit with "recently". And, per TRomano's suggestion below, of the Present Perfect: "recently I read", not "recently I've read".
