Opinion

*389Motion to Exclude Plaintiffs' Experts

Defendants move to exclude the reports, opinions, and testimony of five of Plaintiffs' disclosed expert witnesses: David Carpenter, M.D. ("Dr. Carpenter"), Jeanne Hubbuch, M.D. ("Dr. Hubbuch"), Martha Herbert, M.D. ("Dr. Herbert"), Karl Maret, M.D., Ph.D. ("Dr. Maret"), and Robert Bowdoin ("Mr. Bowdoin").

Per Federal Rule of Evidence 702, a witness who is qualified as an expert may testify in the form of an opinion or otherwise provided that

(a) the expert's scientific, technical, or other specialized knowledge will help the trier of fact to understand the evidence or to determine a fact in issue;
(b) the testimony is based on sufficient facts or data;
(c) the testimony is the product of reliable principles and methods; and
(d) the expert has reliably applied the principles and methods to the facts of the case.

Fed. R. Evid. 702. In applying Rule 702, the court qualifies expert testimony by "ensuring that [it] ... both rests on a reliable foundation and is relevant to the task at hand." Daubert v. Merrell Dow Pharm. , 509 U.S. 579, 597, 113 S.Ct. 2786, 125 L.Ed.2d 469 (1993). In seeking to introduce expert testimony, the plaintiff has the burden of establishing its reliability. See U.S. ex rel. Loughren v. UnumProvident Corp. , 604 F.Supp.2d 259, 264 (D. Mass. 2009).

A. David Carpenter, M.D.

Plaintiffs provided the expert testimony of Dr. Carpenter to prove general causation-that EHS is a real, albeit rare, phenomenon. Dr. Carpenter received his medical degrees from Harvard Medical School, is the Director of the Institute for Health and the Environment at the University of Albany, and a Professor of Environmental Health Sciences within the School of Public Health. He is a researcher and educator on the subject of environmental causes of human disease, and his education and experience support his opinions as set forth in his expert Statement. Docket No. 59-3.

Dr. Carpenter generally opines that exposure to electromagnetic fields ("EMFs") can, in some people, cause EHS, the symptoms of which are consistent with those reported by G. Dr. Carpenter also suggests that it is biologically plausible that the symptoms described could be caused by the known biological effects of EMFs. Defendants move to exclude Dr. Carpenter's testimony on the grounds that his opinions are not based on reliable methods of assessing scientific evidence, and are outside the consensus of the relevant scientific community.

If an expert's testimony is within "the range where experts might reasonably differ," the jury, not the trial court, should be the one to "decide among the conflicting views of different experts." United States v. Zolot , 968 F.Supp.2d 411, 417 (D. Mass. 2013). As the First Circuit instructed in Ruiz-Troche v. Pepsi Cola of Puerto Rico Bottling Co. , 161 F.3d 77, 85 (1st Cir. 1998),

Daubert does not require that a party who proffers expert testimony carry the burden of proving to the judge that the expert's assessment of the situation is correct. As long as an expert's scientific testimony rests upon 'good grounds, based on what is known,' it should be tested by the adversary process-competing expert testimony and active cross-examination-rather than excluded from jurors' scrutiny for fear that they will not grasp its complexities or satisfactorily weigh its inadequacies. In short, Daubert neither requires nor empowers trial courts to determine which of several competing scientific theories has the best provenance. It demands *390only that the proponent of the evidence show that the expert's conclusion has been arrived at in a scientifically sound and methodologically reliable fashion.

Ruiz-Troche , 161 F.3d at 85 (citing Daubert , 509 U.S. at 590, 596, 113 S.Ct. 2786 ; Kannankeril v. Terminix Int'l, Inc. , 128 F.3d 802, 806 (3d Cir.1997) ; In re Paoli R.R. Yard PCB Litig. , 35 F.3d 717, 744 (3d Cir.1994) ).

The Defendants most pointed attack on the admissibility of Dr. Carpenter's opinion is that it is not based on reliable methods of scientific evidence. Defendants note that Dr. Carpenter credits studies and parts of studies that support the hypothesis that EHS exists, and discards or rejects studies or parts of studies that do not confirm this. Defendants refer to this as "cherry picking," and evidence that Dr. Carpenter lacks objectivity, and is merely an advocate or "hired gun." However, if the Court looks at the heart of Dr. Carpenter's opinion-EHS is a rare but real phenomenon-then the fact that a few studies confirm that some individuals manifest EHS while most studies do not, is entirely consistent with his opinion. Rather than "cherry picking," Dr. Carpenter offers detailed methodological criticism of certain studies by providing an expert opinion as to why they might be unable to detect EHS. Such differences of opinion between experts need to be weighed by fact finders.

Regarding Defendants' arguments that Dr. Carpenter's opinions are outside the consensus of the relevant scientific community, the Court notes that it does not exclude a minority view merely because it is a minority view. To the extent Defendants argue that Dr. Carpenter's opinion concerning "no safe threshold" cannot be validated, the "no safe threshold" argument is not essential to the testimony that he offers. Dr. Carpenter's education and Considering Dr.
