She has been the Treasurer for the British Fertility Society from 2020 to date.

Dr Jansa Perez is interested in all aspects of gamete function and embryo development, mostly for clinical application but also for research. She has led several very successful embryology laboratories and as such has a wealth of knowledge in best practice, quality management systems and legal requirements. She focusses her and her teams practice on constant improvement and patient centered evidence-based care.

Dr Jansa Perez is interested in embryo culture and cryopreservation and as such her laboratory participated in the e-freeze trial. She has been involved in research on gene expression in granulosa cells as well as the use of Kisspeptin to induce ovulation whilst reducing the risk of ovarian hyperstimulation syndrome. She is currently doing some research comparing different AI systems to optimise the selection of embryos for transfer.

Dr Jansa Perez is an Honorary Senior Lecturer at Imperial College London, where she teaches and supervises students and embryology trainees in the STP scheme. She has trained laboratory practitioners and embryologists under the ACE scheme and participated in educational sessions for GPs and other healthcare professionals. She regularly teaches at BFS Study Week and STEM events, and has conducted educational sessions on research, embryology, and QMS, as well as courses abroad at the Universitat Autonoma de Barcelona, in India, and in clinics in Nigeria.
