International Work

I pursue solutions that innovate postsecondary STEM teaching and help people overcome science denial. 


In particular, I am motivated when challenges in my local context in the United States run parallel to those of other places in the world. Together as a team, we can work to change our university institutions, better educate the public and future STEM leaders, and ultimately change the world.

Since 2018, I have been involved with the STESSA project (supported by USAID) in Egypt. We work with Egyptian faculty to develop unique postsecondary courses that help future STEM teachers (our university students) solve Egypt's Grand Challenges. 

Our work includes a complete professional development plan for faculty from 5 universities to grow in their skills to facilitate active learning and inquiry-based labs.


I have done faculty development workshops in collaboration with CESPU -  Cooperativa de Ensino Superior Politécnico e Universitário in Gandra, Portugal as the faculty began to implement active learning in all of their STEM courses in Fall 2022.

Language Skills

Dr. Walter speaks and understands most Spanish and is working to learn Arabic and Portuguese.

I also know some American Sign Language. 

I am flexible in working with a translator and enjoy working in contexts with norms and technologies different than the United States. 

Hablo y entiendo Español y estoy aprendiendo a Arabe y Portugués. Tambien yo se un poco lengua de signos Americana. Soy flexible cuando estoy trabajando con un traductor y me gusta contextos con normas y tecnología diferente de los Estados Unidos.
