The man, whose name was not reported, allegedly attacked his wife over his suspicion that she had been unfaithful, Swedish news agency TT reported Wednesday.
"It was honor related. He doesn't seem to regret a thing; he believes she insulted him," said an unidentified source with knowledge of the case told Aftonbladet newspaper.
During a remand hearing, a court ruled the researcher be charged with aggravated assault and ordered him held on remand until formal charges are filed.
Ingela Hessius Ekman, the victim's lawyer, told Aftonbladet that the woman suffered both physical and emotional injuries from the attack.
"She has very serious injuries; the doctors can't yet say whether or not she can be healed," Ekman said.
