While at the ACLU, I also conducted data analysis for litigation and advocacy, and I continue to consult occasionally on data-related issues. Most recently, I contributed analysis in support of the ACLU's intervention opposing Texas's challenge to the Biden administration's moratorium on interior deportations. Under the Trump Administration, I submitted data-related declarations in cases challenging extreme delays in bringing detained noncitizens before an immigration judge, prolonged detention without a bond hearing, ICE's removal of the bond and release options from its risk classification software, and the Trump Administration's decision to deny asylum seekers bond hearings. I also deposed officials from ICE and the immigration courts to obtain information about immigration enforcement data in our case challenging unaffordable bonds.
