Tereza Tewelde Paulos, a native and citizen of Eritrea, petitions this court for review of a decision by the Board of Immigration Appeals summarily affirming the Immigration Judge’s denial of Paulos’s application for asylum, withholding of removal, and relief under the Convention Against Torture (“CAT”). 1

To demonstrate that she is a refugee, Paulos needed to make a showing of “persecution or a well-founded fear of persecution on account of race, religion, nationality, membership in a particular social group, or political opinion.” 2 An applicant “may qualify as a refugee either because ... she has suffered past persecution or because ... she has a well-founded fear of future persecution.” 3 A finding of past persecution gives rise to a presumption of a well-founded fear of future persecution; however, that presumption may be rebutted if a preponderance of the evidence demonstrates that conditions have changed. 4 The IJ determined that Paulos’s assertions of past persecution on account of a protected ground were not credible.

Paulos has failed to address the IJ’s adverse credibility determination in her petition for review and, thus, any challenge to this determination is waived. 5 Even had Paulos challenged the IJ’s credibility findings, the record does not compel a contrary conclusion. 6 Consequently, we need not consider the IJ’s alternative determination that the government had rebutted any presumption that had been raised as to a well-founded fear of persecution.

Paulos concedes that she is not eligible for voluntary departure. Paulos also concedes that as the standards for withholding of removal and relief under the CAT are higher than the standard required to obtain asylum, if she fails in her request for asylum, her requests for withholding of *1001 removal and relief under the CAT likewise fail.

Accordingly, Paulos’s petition for review is DENIED.
