United States Court of Appeals FOR THE DISTRICT OF COLUMBIA CIRCUIT

XUNXIAN LIU, APPELLANT

v.

GEORGETOWN UNIVERSITY, APPELLEE

Appeal from the United States District Court for the District of Columbia (No. 1:22-cv-00157)

Before: MILLETT, WILKINS, and GARCIA, Circuit Judges.

JUDGMENT

The cause came to be heard on the record on appeal from the United States District Court for the District of Columbia and on the briefs of the parties. The panel has accorded these issues full consideration and decided that they do not warrant a published opinion. See D.C. CIR. R. 36(d). For the reasons stated below, it is hereby

ORDERED and ADJUDGED that the judgment of the United States District Court for the District of Columbia be AFFIRMED.

* * *

Dr. Xunxian Liu, a biomedical researcher formerly employed by Georgetown University (the “University”), brought an action against the University alleging discrimination and retaliation in violation of Title VII of the Civil Rights Act of 1964 (“Title VII”), the Age Discrimination in Employment Act (“ADEA”), 42 U.S.C. § 1981 (“Section 1981”), and the District of Columbia Human Rights Act (“DCHRA”), as well as related constitutional claims arising from his employment in Dr. Alexander Kroemer’s laboratory. The District Court granted the University’s motion for judgment on the pleadings and dismissed all the claims against the University. Dr. Liu filed a motion for reconsideration, which the District Court denied.

At the judgment on the pleadings stage, we must view the allegations in the light most 2

favorable to Dr. Liu as the non-moving party, granting him all reasonable inferences. See Schuchart v. La Taberna Del Alabardero, Inc., 365 F.3d 33, 34 (D.C. Cir. 2004). We hold that the District Court erred in conducting its comparator analysis for the claims of national-origin discrimination when it held Dr. Liu to the stricter standard that applies at the summary-judgment stage, rather than the pleading standard that applies at the motion-to-dismiss stage. See Joyner v. Morrison & Foerster LLP, 140 F.4th 523, 530–31 (D.C. Cir. 2025). Nonetheless, we conclude that, applying the proper standard, Dr. Liu has failed to state a claim that the University unlawfully discriminated and retaliated against him based on his national origin. Dr. Liu’s remaining claims also fail for reasons of inadequate pleading, lack of exhaustion, or lack of redressability. We therefore affirm the District Court’s dismissal of all Dr. Liu’s claims. We further hold that the District Court did not abuse its discretion in denying Dr. Liu’s motion for reconsideration.

I.

A.

The Court draws the following facts from Dr. Liu’s Second Amended Complaint, which are accepted as true for purposes of this appeal. See Bell Atl. Corp. v. Twombly, 550 U.S. 544, 555 (2007). This Court will also consider documents that are referred to in the Complaint and his filings as “integral” to Plaintiff’s claims. See Banneker Ventures, LLC v. Graham, 798 F.3d 1119, 1133 (D.C. Cir. 2015) (quoting Kaempe v. Myers, 367 F.3d 958, 965 (D.C. Cir. 2004)); see, e.g., Brown v. Whole Foods Mkt. Grp., Inc., 789 F.3d 146, 152 (D.C. Cir. 2015) (“We have previously held that a district court errs in failing to consider a pro se litigant’s complaint “in light of” all filings, including filings responsive to a motion to dismiss.”) (internal citations omitted).

Dr. Xunxian Liu is a Chinese-born biomedical sciences researcher who came to the United States at age 36 to pursue a Ph.D. in biomedical sciences. Dr. Liu began working at Georgetown University in January 2017 as a temporary Research Specialist, in the lab of Dr. Alexander Kroemer, M.D., a transplant surgeon and the Scientific Director of the Center for Translational Transplant Medicine. He was hired as a Research Associate in April 2019, a term position under the supervision and research funding of Dr. Kroemer. His position was at-will and subject to a three-month probationary period.

In the laboratory, Dr. Liu worked alongside two other employees, Dr. Katrina Loh, M.D. and Dr. Jiman Kang, Ph.D. Dr. Loh is a female medical fellow from Malaysia, roughly 33 years old whose fellowship was funded by the Children’s Medical Center Hospital. Dr. Loh was hired in July 2018, a little under a year prior to Dr. Liu being hired into a term position. Dr. Kang is a male research assistant from South Korea who was “not [yet] 40” years old, whose position was also funded by Dr. Kroemer’s research funding. He was hired in April 2017, around two years prior to Dr. Liu being hired into a term position.

There are four incidents that are central to Dr. Liu’s discrimination and retaliation claims: (i) Dr. Loh’s alleged first authorship of a study and her presentation of Dr. Liu’s data at two conferences, (ii) Dr. Kroemer’s failure to seek Dr. Liu’s permission for Dr. Loh to present his data, 3

(iii) Dr. Liu’s termination, and (iv) his post-employment efforts to obtain research data from the University. First, Dr. Liu claims that in 2019 Dr. Loh presented an abstract and a poster containing “[his]-produced data” and that “[his] ideas [were a] major contribution[] to the presentation[.]” JA0109. He alleges that Dr. Loh’s presentations “seriously damage[d] [his] rights/privileges associated with [his] position in the lab” because he should have presented the data and been listed as the first author based on his individual contributions. JA0109. Dr. Liu alleges that selecting Dr. Loh to present was discriminatory in nature because Dr. Kroemer “chose the first author based on one’s spoken English level, not one’s contributions to the research[.]” JA0109. According to Dr. Liu, the selection is also discriminatory because Dr. Kroemer selected Dr. Loh “to foster” her as a “young woman[.]” JA0109. Together, the selection of Dr. Loh as the first author and her presentation of the data led to discrimination based on “age, national origin and sex.” JA0111. Dr. Liu also alleges that Dr. Kroemer’s conduct reflected racial discrimination, since Dr. Kroemer had previously granted first authorship to unnamed, white researchers who played similar roles in other projects. JA0110–11. No further information was ever provided about the white researchers.

With regard to the second incident, Dr. Liu alleges that Dr. Kroemer did not seek his permission before allowing Dr. Loh to present the data, which resulted in “discrimination in age and national origin[.]” JA0111. In the Complaint, Dr. Liu also alleges that this decision may also be sex discrimination. See JA0109. To support his claim, Dr. Liu compares his treatment to that of his colleague, Dr. Kang. Dr. Liu alleges that Dr. Kroemer asked Dr. Kang to allow Dr. Loh to take first authorship on “Kang’s study,” but Dr. Kang refused, saying he felt “uncomfortable.” JA0109. Dr. Liu contends that Dr. Kroemer’s decision to consult Dr. Kang but not him amounted to “triple age/national origin discrimination.” JA0110. Finally, Dr. Liu concludes that this differential treatment reflected the University’s preference for younger, non- Chinese researchers and demonstrated the University’s broader pattern of discriminatory favoritism within Dr. Kroemer’s lab. Appellant’s Br. 1–4.

As for the third incident, Dr. Liu contends that his termination was both discriminatory and retaliatory for raising his concerns regarding the instances highlighted above.
