Opinion

STEELE, Chief Justice:

In this action, a group of Texas plaintiffs allege that a corporation exposed two employees to chemicals that caused two of the employees’ children to suffer from birth defects. On appeal, the plaintiffs challenge a Superior Court judge’s application of Texas substantive law and the resulting exclusion of expert testimony. Under Delaware law, which incorporates the United States Supreme Court’s holding in Daubert v. Merrell Dow Pharmaceuticals, Inc.,1 admissible expert testimony must be both relevant and reliable. The Superior Court judge excluded the expert testimony as irrelevant under Delaware law because it would be insufficient as a matter of Texas law. The judge did not reach the testimony’s reliability under Delaware law. Because the plaintiffs waived their argument that California or Delaware substantive law applies, we AFFIRM the Superior Court judge’s ruling that Texas substantive law applies. Before we address whether a judge may consider substantive sufficiency when analyzing procedural admissibility, a question on which other jurisdictions disagree, we REMAND so that the Superior Court judge may determine in the first instance whether the testimony at issue is excludable on reliability grounds.

I. FACTUAL AND PROCEDURAL HISTORY2

Defendant-Appellee Advanced Micro Devices, Inc., (AMD) is a Delaware corpo[986]*986ration headquartered in California. AMD employed Plaintiff-Appellant Wendolyn Tumlinson and Plaintiff-Appellant Paris Ontiveros’s father, Anthony Ontiveros, in two of its Texas semiconductor manufacturing facilities. Wendolyn3 worked in a San Antonio photolithography department; Anthony worked in an Austin etching department. Plaintiff-Appellants Wendolyn Tumlinson, Jake Tumlinson, Jillveh On-tiveros, and Paris Ontiveros (collectively, Tumlinson)4 contend that Wendolyn’s and Anthony’s exposure to workplace chemicals caused Jake and Paris to suffer from birth defects. On July 11, 2008, Tumlin-son sued AMD in Superior Court for negligence, premises liability, strict liability, abnormally dangerous ultrahazardous activity, and willful and wanton misconduct.

On March 16, 2010, AMD filed a Motion to Apply Texas Law to Issues of Liability and Damages.5 The Superior Court judge granted AMD’s motion and ruled that Texas substantive tort law, Delaware eviden-tiary law, and Delaware procedural law apply.6

Tumlinson intended to offer Dr. Linda Frazier’s expert opinion that Wendolyn’s and Anthony’s exposure to chemicals while they were AMD employees caused Jake’s and Paris’s birth defects.7 On December 15, 2010, AMD moved to exclude Frazier’s opinion,8 arguing that it was (1) irrelevant and (2) unreliable.9 After a four-day evi-dentiary hearing, the Superior Court judge granted AMD’s motion to exclude Frazier’s testimony.10 Tumlinson sought an interlocutory appeal, but we refused her petition.11 The parties stipulated to final judgment in AMD’s favor so that Tumlin-son could appeal the Superior Court judge’s decisions applying Texas law and excluding Frazier’s testimony.12

II. STANDARD OF REVIEW

Choice of law is a legal question that we review de novo.13 We review a [987]*987trial judge’s decision to admit or exclude expert testimony for abuse of discretion.14 We also grant a trial judge “broad latitude to determine whether” expert testimony contains “reasonable measures of reliability in a particular case” and accordingly review a judge’s ruling on the reliability of an expert’s methodology or ultimate conclusion for abuse of discretion.15

III. ANALYSIS

A. Choice of Law

Before deciding whether the expert testimony is admissible, we must determine which state’s law governs the analysis. The Superior Court judge ruled that Texas substantive law and Delaware procedural law (including evidentiary law) apply.16 Because we hold that Tumlinson waived her arguments that California or Delaware substantive law apply,17 we affirm the Superior Court judge’s opinion to the extent that he concluded that Delaware procedural and Texas substantive law apply.

“As a general rule, the law of the forum governs procedural matters,”18 in-eluding whether evidence is admissible.19 Therefore, the Superior Court judge properly concluded that Delaware law governs the procedural matters in this case. To determine which jurisdiction’s substantive law applies in a tort suit, we follow the Restatement (Second) of Conflict of Laws approach.20 Section 145(1) states that we apply the law of the state that has the “most significant relationship to the occurrence and the parties under the principles stated in [Section] 6.”21 Additionally, Section 145(2) lists several additional factors we must examine when evaluating which state has the most significant relationship to the case: (1) “where the injury occurred,” (2) “where the conduct causing the injury occurred,” (8) the parties’ “dom-icil, residence, nationality, place of incorporation and place of business,” and (4) where the parties’ relationship is centered.22 Finally, Section 146 creates a strong presumption that the “law of the state where the injury occurred” governs unless another state “has a more significant relationship.”23

[988]*988Tumlinson argues in her Opening Briefs summary section that choice-of-law rules require us to apply Delaware or California law.24 She also notes in a footnote in her argument section that it was error for the Superior Court judge to even address the choice-of-law question because no conflict existed,25 which could be construed as an assertion that Delaware substantive law should apply.26 Even assuming that these scattered assertions are an argument that Delaware substantive law, rather than procedural law, should apply, Tumlinson has waived the argument.

Our case law clearly states that an appellant’s opening brief must “fully state the grounds for appeal, as well as the arguments and supporting authorities on each issue or claim of reversible error.”27 An appellant who raises an issue in her opening briefs summary section must pursue it in the argument section or the issue will be deemed waived.28 Similarly, an appellant may not preserve issues by raising them in footnotes.29 “If an appellant fails to comply with these requirements on a particular issue, the appellant has abandoned that issue on appeal irrespective of how well the issue was preserved at trial.” 30
