  • My name is Valeria and I am originally from Puerto Rico, where I majored in psychology at the University of Puerto Rico and received my degree this year.  During my undergraduate studies, I had several jobs such as being a Youth Advisor for the Puerto Rico Department of Health and completed the SEO Law Fellowship before starting at Columbia.  At Columbia, I am a 1L staffer for the Journal of Gender and Law, participant in the LaLSA Asylum and Refugee Law Moot Court, and a 1L Events Representative for ACLU-CLS.  Although I am interested in litigation and civil rights, I do keep an open mind as to potential areas of interest as I navigate law school.  I also am a photographer and enjoy exercising and exploring NYC's restaurant scene.

  • Josceline is a 1L with an Associate's degree in Business Administration from Miami-Dade College and a BA in Accounting from the University of Miami. Prior to law school, I worked in Assurance and Advisory at a regional public accounting firm in South Florida. I obtained my Certified Public Accountant License from the Florida Board of Accountancy in 2020. I'm committed to criminal legal reform but am also interested in prison litigation and the development of human rights. For several years I worked with a non-profit reentry organization that assists in finding employment opportunities for formerly incarcerated persons. My responsibilities varied but were usually related to mitigating the socio-economic strain of a criminal record post-incarceration. In my very limited off-time, I enjoy watching Turkish drama series, and exploring nearby sights. 

  • Henry Goldberg is a 1L from Dallas, Texas. Before coming to Columbia Law School, he attended Vanderbilt University, graduating in May 2020, where he picked up a passion for voting rights as well as immigration policy, focusing in particular on refugee law. As a first-year student there in Fall 2016, frustrated with the school’s ineffective voter registration efforts, he researched state laws to create a spreadsheet to help his fellow students register to vote and request their absentee ballots. The online resource racked up hundreds of views, and he used it in-person to help over fifty people. Also during college, he took multiple classes on refugee law and performed research on it, earning a spot in the acknowledgments section of a forthcoming journal article. At Columbia Law, in addition to his work with ACLU-CLS, he is excited to be a part of the LaLSA Moot Court and the SIRR Presidential Team and to be helping with refugee casework through IRAP.
