(´15) both at New York University. Besides teaching Criminal Law, Professor Lorca also teaches a seminar on Punishment and Poverty, Law and Literature, and a thesis seminar both for the Master in Criminal Law and the Doctoral Program of Universidad de Chile´s School of Law.

    Professor Lorca´s research focuses on the relationship between criminal justice and other spheres of justice such as economic justice, political justice and principles of the Rule of Law. During her dissertation she studied the relationship between criminal and economic justice by trying to make sense of the intuition that our practice of holding people responsible through criminal law is not fully warranted when it comes to victims of severe economic injustice. The findings of this investigation have been partially published in articles in both English and Spanish.

    During her visit at UCLA she will work on an investigation about the idea of impunity, its meanings and importance. She will try to answer the following questions: What do we mean when we talk about impunity as a political or institutional failure in the context of international criminal law? What should be the ends and limits of the quest against impunity? Why we care so much about it? What is the normative issue with impunity? And, is the international criminal court suited to fight against it?

A primary focus of the organization is to help law students volunteer with agencies that provide free or low-cost legal services for low-income immigrants. Students who volunteer with the VAWA Clinic work with attorneys at the Central American Resource Center (CARECEN) to prepare declarations for victims of serious crimes, including domestic violence, in order to apply for U-Visas and VAWA. Students also volunteer with the Youth Deportation Defense Clinic, in conjunction with the Esperanza Immigrant Rights Project, by conducting legal screenings for minors to help the family identify potential defenses to deportation and connect the child with free or low-cost representation.

  • Foreign Legal Study and Exchange Program

    Through its Foreign Legal Study and Exchange Program, UCLA School of Law offers various opportunities for its students, and for law students in other countries, to gain exposure to international law and the legal systems and cultures of other nations.

    UCLA School of Law has partnered with many leading academic institutions in Europe, Asia, Israel, Australia and South America to establish the Foreign Legal Study and Exchange Program (FLSEP). Under exchange agreements with these partner schools, UCLA School of Law will host the most highly qualified students from its partner schools, while similarly talented and committed UCLA law students may sample the intellectual and cultural riches that partner schools offer.

    The program is highly selective - each semester, each partner school may normally nominate only up to two students to attend UCLA School of Law for a semester, and UCLA School of Law may normally nominate only up to two students to attend each partner school for a similar academic term. Well-qualified candidates are strongly encouraged to apply.
