Kateřina Ronovská (born on 9 June 1974 in Brno) graduated from the Faculty of Law of Masaryk University in Brno, which is her home to this day. She decided to stay in academia. Therefore, she went to complete a postgraduate study programme at the same faculty and later worked in various academic positions. She headed the Department of Civil Law there from 2019 until her appointment as a Justice of the Constitutional Court. Masaryk University awarded her the title of professor of civil law in 2021.

She has completed several long-term study and research stays abroad in the Netherlands (Vrije Universiteit, Amsterdam, 2001), Switzerland (Institute Suisse Droit Comparé, Lausanne, 2001), Germany (Max Planck Institute für ausländisches und internationales Privatrecht, Hamburg, 2012, 2017, 2018) and also went to Israel as a visiting professor (IDC Herzlyia, 2020).

She mainly specialises on private law, especially personal law in the legal sense, association law, and foundation and trust law in the context of international comparison. In recent years, she has also focused on the administration of the property of others (family). Although she is a career academic, she has never been "detached" from practice of law. As an expert, she has cooperated with a number of law firms and non-profit organisations in finding solutions to complex interpretive problems, and she regularly lectures to judges, attorneys, notaries, and tax advisors. In 2016–2017, she was a member of an arbitral panel of the ICC International Court of Arbitration in Paris.

Kateřina Ronovská is the author of monographs, textbooks and commentaries, and co-researcher of several international comparative projects. She regularly publishes in both Czech and foreign scientific journals. She is an active participant in discussions on the state and development of (new) private law and on the issues of higher education, science and research. She is a member of the scientific councils of the Masaryk University in Brno and the Palacký University in Olomouc. From 2022 to 2023 she was a member of the Council for Research, Development and Innovation, which is an advisory body to the Government of the Czech Republic.

In her activities to help build an appropriate legal environment for the functioning of foundations, endowment funds and associations and to develop philanthropy in the Czech Republic and Europe, she was a long-standing member of the Committee on Funding and Legislation of the Government Council for Non-Governmental Non-Profit Organisations. She has also served on the boards of several Czech foundations and endowment funds.

In 2014, she was awarded a Medal of Gratitude by the Czech Scouting Organisation.

She like to spend her free time with family, travelling and engaging in sports.

The President of the Czech Republic appointed her a Justice and Vice-President of the Constitutional Court on 4 August 2023.
