The opinion of the court was delivered by: Herndon, Chief Judge:
Now before the Court is plaintiff's motion in limine ("Daubert" motion) relating to exclude opinions of IASB's expert, Dr. Lars Bjork (Doc. 104). Plaintiff argues that Bjork is not qualified to render the opinions in his report, that his methodology is not scientifically valid and that his opinions will not assist the tier of fact and that they are irrelevant. Defendant opposes the motion (Doc. 113). Based on the following, the Court denies the motion.
This is an age discrimination and retaliation case against IASB and Highland Community Unit School District No. 5 brought pursuant to the Age Discrimination in Employment Act ("ADEA") and the Illinois Human Rights Act ("IHRA"). In his complaint, plaintiff alleges defendant IASB is an employment agency which was seeking applicants on behalf of defendant Highland for the position of Superintendent. Plaintiff alleges that he contacted defendant IASB about potentially applying for that position and that Larry Dirks, an employee of defendant IASB, told him that Highland was looking for someone younger for the Superintendent position. Plaintiff claims that he nonetheless submitted an application for the Highland position to defendant IASB and that defendant IASB did not forward his name to defendant Highland. Defendant Highland eventually hired someone younger than plaintiff for the position.
Federal Rule of Evidence 702 and in particular Daubert, govern the admissibility of expert testimony. The Daubert standard applies to all expert testimony, whether based on scientific competence or other specialized or technical expertise. Smith v. Ford Motor Co., 215 F.3d 713, 719 (7th Cir. 2000) (citing Kumho Tire Co., Ltd. v. Carmichael, 526 U.S. 137, 141 (1999)); Tyus v. Urban Search Mgmt., 102 F.3d 256, 263 (7th Cir.1996) ( Daubert' s "framework for assessing expert testimony is applicable to social science experts, just as it applies to experts in the hard sciences."). Rule 702 provides:
If scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education, may testify thereto in the form of an opinion or otherwise, if (1) the testimony is based upon sufficient facts or data, (2) the testimony is the product of reliable principles and methods, and (3) the witness has applied the principles and methods reliably to the facts of the case.
Daubert clarified that Rule 702 charges the district court with the task of ensuring expert testimony is both relevant and reliable. Daubert, 509 U.S. at 589. Courts in the Seventh Circuit conduct a three-step analysis. Ervin v. Johnson & Johnson, Inc., 492 F.3d 901, 904 (7th Cir. 2007).*fn1 First, the district court must determine whether the person whose testimony is offered is in fact an expert, as codified in Rule 702 through "knowledge, skill, experience, training or education." Id. (citing FED. R. EVID. 702). Notably, although "extensive academic and practical expertise" sufficiently qualify a potential witness as an expert, Bryant v. City of Chi., 200 F.3d 1092, 1098 (7th Cir. 2000), "Rule 702 specifically contemplates the admission of testimony by experts whose knowledge is based on experience," Walker v. Soo Line R.R. Co., 208 F.3d 581, 591 (7th Cir. 2000); see Smith, 215 F.3d at 718 ("[N]o one denies that an expert might draw a conclusion from a set of observations based on extensive and specialized experience.") (citing Kumho, 526 U.S. at 156)).
Secondly, the district court must determine whether the expert's reasoning or methodology is reliable. Ervin, 492 F.3d at 904; see Mihailovich v. Laatsch, 359 F.3d 892, 918 (7th Cir. 2004) (citing Kumho, 526 U.S. at 147). Specifically, the testimony must have a reliable basis in the knowledge and experience of the relevant discipline, Kumho, 526 U.S. at 149 (internal quotations removed), consisting in more than subjective belief or unsupported speculation. Chapman, 297 F.3d at 687; Daubert, 509 U.S. at 590.
Further, as to reliability, Daubert provided the following non-exhaustive list of relevant factors: "(1) whether the scientific theory can be or has been tested; (2) whether the theory has been subjected to peer review and publication; (3) whether the theory has been generally accepted in the scientific community." Ervin, 492 F.3d 901, 904 (7th Cir. 2007) (citing Daubert, 509 U.S. at 593-94). However, there is no requirement that courts rely on each factor, as the gatekeeping inquiry is flexible and must be "tied to the facts" of the particular case. Kumho, 526 U.S. at 150 (quoting Daubert, 509 U.S. at 591); see also Chapman, 297 F.3d at 687. Thus, "the role of the court is to determine whether the expert is qualified in the relevant field and to examine the methodology the expert has used in reaching his [or her] conclusions." Smith, 215 F.3d at 718 (citing Kumho, 526 U.S. at 153).
The district court possesses "great latitude in determining not only how to measure the reliability of the proposed expert testimony but also whether the testimony is, in fact, reliable." United States v. Pansier, 576 F.3d 726, 737 (7th Cir. 2009) (citing Jenkins v. Bartlett, 487 F.3d 482, 489 (7th Cir. 2007)). Accordingly, the court's gatekeeping function requires focus on the expert's methodology, i.e., the "[s]oundness of the factual underpinnings of the expert's analysis and the correctness of the expert's conclusions based on that analysis are factual matters to be determined by the trier of fact." Smith, 215 F.3d at 718 (citing Daubert, 509 U.S. at 595; Walker, 208 F.3d at 587). However, an expert must explain the methodologies and principles that support his or her opinion; he or she cannot simply assert a "bottom line" or ipse dixit conclusion. Metavante Corp. v. Emigrant Sav. Bank, 619 F.3d 748, 761 (7th Cir. 2010) (quoting Minix v. Canarecci, 597 F.3d 824, 835 (7th Cir. 2010)).
Lastly, the district court must consider whether the proposed testimony will assist the trier of fact in its analysis of any issue relevant to the dispute. See Smith, 215 F.3d at 718; Chapman, 297 F.3d at 687; Daubert, 509 U.S. at 592. It is crucial that the expert "testify to something more than what is 'obvious to the layperson' in order to be of any particular assistance to the jury.'" Dhillon v. Crown Controls Corp., 269 F.3d 865, 871 (7th Cir. 2001) (quoting Ancho v. Pentek Corp., 157 F.3d 512, 519 (7th Cir. 1998)). However, the expert need not ...
