Monalisa presently holds various leadership positions in the government and private sectors. She is Chairperson of the Philippine National Renewable Energy Board (NREB) since her appointment by the Philippine President on 28 March 2019. In this post, she steers the performance by the Board in its mandate of monitoring the implementation of programs established under the Philippine Renewable Energy Act of 2008 or the RE Act (Republic Act No. 9513) and in formulating recommendations for new programs and policies to the Department of Energy (DOE) towards achieving the renewable energy targets of the country.

Monalisa is also a Senior Partner in PJS Law, a full-service law firm she joined in August 2001. Until her assumption of office as NREB Chair, she was leading the Energy Group of the Firm. While her government post permits continued practice of profession, it precludes her from representing clients in the energy space. Thus, she continues to support the Firm in the training of junior lawyers in practice and leads the Firm’s programs on innovation in legal services. One of such innovation projects has led to the creation of UNAWA Asia, an inclusive startup company formed as a result of collaboration between PJS Law and Talino Venture Labs SG. UNAWA provides digital solutions to medium, small and micro enterprises (MSMEs) for compliance with corporate and regulatory, including data privacy, requirements. Since the establishment of the company in November 2019, Monalisa sits as its President and CEO.

She is also a professor at the Ateneo de Manila Law School teaching Energy Law, Global Legal Practice, and Negotiable Instruments Law. This September 2020, she is also pursuing further studies as she enters the National University of Singapore (NUS) Lee Kuan Yew School of Public Policy for the Senior Fellowship Programme for Public Policy.
