Karla Zambrano González is an Assistant Professor of Private International Law in the "Adolfo Miaja de la Muela" Department of International Law at the University of Valencia. Her doctoral thesis was entitled “The Challenge of Climate Change in International and European Law” and received the highest grade: Summa Cum Laude and International Mention.

She has held a pre-doctoral and post-doctoral fellowship from the Ministry of Science and Universities and currently maintains an interest in different lines of research related to her thesis topic. One of these lines is the study of European public policy scenarios in the field of energy in collaboration with the Polytechnic University of Valencia (ECHO). Another of these areas focuses on mechanisms for adaptation to climate change and protection of the marine environment. This gave her the oppotunity of being granted a second postdoctoral fellowship, CIAPOS/2023/181, funded by the Generalitat Valenciana, in the AGUDEMA research group at the University of Zaragoza. Recently, following her appointment as Assistant Professor, she has embarked on three new lines of research: (i) the sustainability of non-state actors, (ii) the individual transition to resilient agri-food diets and the reasons for the settlement of migrants in rural areas at risk of depopulation, and (iii) the circular economy, entrepreneurship, and migrant women.

She actively collaborates in legal research as an external expert in the ICTvsCC Group of the Institute of Information and Communication Technologies (ITACA) at the Polytechnic University of Valencia (UPV) and was named Juan de la Cierva Researcher in the 2023 Call for Applications, but declined the position due to incompatibility with her current academic status.

For more than six years, she has focused on university teaching. She has been a Lecturer of Public International Law and International Environmental Law at the University of Valencia, where she taught these subjects in Spanish, Valencian, and English. She has also been Lecturer at the International University of La Rioja (UNIR), where she has been in charge of the following subjects: Citizenship and Human Rights: Borders and Migration; and Human Rights, New Technologies, and Biolaw, both part of the Master's Degree in Human Rights: Protection Systems. In addition, she has supervised numerous Master's Theses for the Master's Degree in Law and Advocacy, the Master's Degree in Environmental Law, and the Master's Degree in Human Rights. Thanks to her experience in the legal field and international commercial operations, he has also taught the subject of Commercial Law in the Bachelor's Degree in Labor Relations at UNIR.

As part of her teacher training, she has taken several courses and seminars on Educational innovation and has completed her Master's Degree in Secondary Education Teaching at the University of Valencia, with an outstanding grade point average, thus obtaining pedagogical skills and extensive knowledge in terms of teaching innovation and new methodologies applied to the European education framework.

In terms of her development as a researcher, she stands out as an active member of the UV's own research group: “Sustainable Development, Global and Regional Governance, Contemporary International and European Order - DSGMROIEC.” She is also recognized for her research activity at the Polytechnic University of Valencia, as a member of the Institute of Information and Communication Technologies (ITACA-UPV), under the direction of Dr. Javier Urchueguía Schözel, and at the International University of La Rioja, in the DESONT group: Law, Sustainability, and New Technologies. She has been a visiting researcher at the following research centers: the Cambridge Centre for Environment, Energy and Natural Resources Governance (CEENRG) at the University of Cambridge, the Institut de recherche en droit international et européen de la Sorbonne (IREDIES) at the University of Paris 1 Panthéon-Sorbonne, the Centre for International Law and Governance (CILG) at the University of Copenhagen, the Institute of Political Science and Administration at the University of Opole (Poland), and the University of Chicago (Regenstein Library).

As a result of her research activity, she is recognized for her participation in various national and international conferences and seminars, as well as her various publications on the legal treatment of climate change, migration, and human rights. She has been awarded the “Tomás y Valiente” prize from the University of Valencia for the best legal research of 2021 and the “Fernando Sapiña 2022” prize from the same institution for the development of teaching materials in English for the subject of International Environmental Law.
