Marta is a member of the board in MiMer. 

Marta is a modality independent Equine Assisted Learning facilitator, a long time advocate for equine welfare and ethics in equine assisted activities. Marta has over 20 years of experience as teacher and educator and her work now is dedicated to developing education programmes for EAL practitioners and facilitators that are informed as far as equine ethics, welfare and also horse and human trauma.

Her path with horses started unexpectedly after her totally non-horsey family acquired an ex-racing arabian stallion. She’s been living with a small herd of horses since then, learning and growing both as a horsewoman and a human being. Having tried to understand the horse world as an adult she tried many traditional ways of interacting with horses. Her numerous disappointments and unrelenting fascination with horses pushed her to redefine concepts like leadership, freedom and partnership to get to have life with horses. She neither rides nor trains horses.

Marta is also a mediator working in Non-Violent Communication (NVC) approach. Due to her strong connection to children and dedication to her role as a parent she mostly counsels parents, couples, families and teachers. Marta offers supervision to EAL facilitators and practitioners.

She believes in combining horse and human welfare education thus creating a lens of understanding, cooperation and exchange between the two species. She’s created a NGO dedicated to promoting this very idea ( She loves to teach restoration and stress relief together with horses. She’s a great enthusiast of somatic approach to healing and growth.

Emily Kieson

Emily Kieson

Emily Kieson PhD, M.S., PgDip, ESMHL,  (USA)

Emily is a former member of the Board in MiMer. She served as MiMer Centre's Research Director from 2019- august 2022.

Emily has a PhD in Comparative Psychology from Oklahoma State University, a MS in Psychology from Oklahoma State University, a B.S. in Ecology and Evolution from Rutgers University and a Post Graduate Diploma in Equine Science from the University of Edinburgh. She teaches and develops courses at Post University and Unity College and serves on the Equine Welfare Committee of the Professional Association of Therapeutic Horsemanship. Her passion is researching equine behavioral psychology in the context of horse-human interactions with specific focuses on affiliative strategies, social bonding, and positive welfare.

Emily has spent almost 20 years as a multi-disciplinary trainer and instructor in both Texas and Oklahoma and became interested in equine-assisted activities and therapies about ten years ago. She has been trained and certified in a half-dozen models of EAAT and continues to learn about the field. It was during these trainings that she discovered the lack of research in horse-human interactions and became interested (honestly, obsessed) with developing the science in this field. Specifically, Emily is interested in understanding how horses interact with humans in ways that mimic social bonding to help develop better models of equine-assisted psychotherapy that use equine interactions to parallel interpersonal relationships. She also has ambitions of using this to help individuals create better relationships with their horses at home and create more centralized educational resources for horse owners and equine practitioners.

Sonja Lairila, Equine ethics and -relationship consultant & yoga instructor (Finland, Germany)

By being close to horses that had suffered lead her to study equines, and equine-human interaction intensively from different perspectives.

Besides horses, Sonja is a Dynamic Mindfulness yoga instructor, and her passion for movement and mindfulness reaches over to the equine world as well. She is curious about mindful movement experiences, and how that connects to the relationships/interactions with horses. She believes in the power of just being and observing in order to understand, both ourselves, and our equine partners better.

Sonja’s interdisciplinary approach aims to bring a wider understanding and better welfare to the world of equines. Her aim is to help people improve their relationships with their equine partners through mutual understanding and to improve the general welfare and wellbeing of equines (and humans) by education.
