Mateus Maria100pxMaria J. Mateus, has a BA in psychology from the University of Texas and MA in astrology from Kepler College.

Maria believes the key to understanding all of astrology, is to understand the manner in which language and mind reflect the world we live in. In 2002, her desire to demystify the relationship between inner emotional states and outer world manifestations led her to embark on an investigation that culminated in the development of the LINCOS grammatical approach to astrology.

Maria has been a student of astrology since she was a teen. She's open to all astrological schools, but maintains  a particular interest in research, history, language, and ancient techniques.

Maria has lectured at conferences and workshops around the world and taught at the International Academy of Astrology and Kepler College. She's written for several astrological publications, translated a modern introduction to traditional techniques (On The Heavenly Spheres), and is currently translating its sequel, as well as working on her own work on grammatical astrology.

Kepler Instructors are chosen for their expertise in academic and astrological knowledge and for their ability to effectively teach what they know to others in an online environment.

They must be able to produce quality instructional materials that enhance learning by using multiple strategies and approaches. They need to understand how to work with students remotely, and to develop the trust and respect of their students and colleagues.

They also need to stay up-to-date on new developments and examine the interplay of the new and old. And they must be willing acknowledge their own biases so they can present their students with multiple perspectives.
