Donna Falk

 

Donna Falk’s professional journey has been quite diverse, transitioning from her role as a Scientist to becoming a dedicated Middle School Science Teacher and now Instructional Design Expert. Holding a degree in Microbiology from Rutgers University, she initially worked as a scientist, testing orange juice from tanker ships, developing preservatives for various materials, writing technical documents, and contributing to Rutgers University’s Department of Marine and Coastal Sciences.

 

When her children reached middle school, Donna pursued her science teaching certification. With more than 17 years of experience in teaching middle school science, she spent the first 14 years designing and instructing a unique course called Forensic Science. This innovative class linked scientific concepts to crime-solving techniques, engaging every 8th-grade student — over 600 students annually. Through this extensive teaching exposure, she honed her ability to tailor lessons to diverse learning levels and situations.

 

When the pandemic emerged, Donna volunteered to instruct the core 8th grade science curriculum in a fully virtual setting. This undertaking required her to grasp new subject matter and seamlessly adapt it into digital lessons. Despite the challenges, she found immense satisfaction in devising hands-on lab activities that students could perform using minimal supplies, from the comfort of their homes.

 

Donna states that her motivation for becoming a middle school science teacher stemmed from her desire to help students in this age group who might approach science with trepidation. Her greatest joy lies in winning over these hesitant students and demonstrating that science is not only enjoyable and captivating, but also relevant and interconnected with their daily lives.

 

Residing by the sea in Belmar, NJ, Donna shares her home with her husband, Jon, and their mini labradoodle, Ruby.

The University of Miami (UM) welcomed her as she continued her research in multiple fields….Genetics, Cell Biology and Neuroscience at The Miami Project to Cure Paralysis.

In 2007, Irene accepted a position with Dr. J. Hare in The Stem Cell Research Institute at UM.  The labs were focused on translational cardiology and stem cell biology. Here, she was responsible for coordinating all aspects of running the lab. Irene provided technical and administrative guidance and support to the physicians, postdocs and students in the lab. 

 

As a researcher, Irene continued to do experiments to understand the biology of cardiac stem cells in vitro. Each year, as Director of the Stem Cell Summer Volunteer program she had the opportunity to introduce undergraduate students into hands on research.

 

Irene retired from the University in May of 2020.  Retirement has provided the opportunity to study oil painting, read historical fiction, plant a butterfly garden and think about science for the joy of doing so.
