Classification systems help parse life's diversity, and this tutorial examines the three domains framework. Viewers learn how archaea, bacteria and eukarya each exhibit unique traits forming the basis for their domains. Clear examples highlight definitive characteristics like cell structure and genetic mechanisms within representative phyla. The three domains model brings taxonomy to life, helping life science students visualize evolutionary distinctions across nature's full spectrum at a foundational level. With its visual aid and comparative approach, this video consolidates core concepts in microbiology and beyond.

Biology

I have a passion for helping students develop a strong foundation in the biological sciences. I graduated summa cum laude from Harvard University with a bachelor's degree in Molecular and Cell Biology and currently work as a research associate at a biotech firm.

In my lessons, I focus on clearly explaining concepts and equipping students with effective study skills. I understand these subjects can be challenging, so I take a patient approach and empower students to ask questions. My goal is to make biology and chemistry engaging and applicable to students' everyday lives.

In addition to tutoring experience in high schools, I was a teaching assistant for undergraduate biology labs and courses. I have worked with students from middle school through graduate level on topics ranging from cell structures to genetics to biochemistry.

Outside of work, I enjoy running, film photography, and keeping tropical fish. I'm always seeking out new research and hope to share my curiosity for scientific discovery with students. I look forward to helping your understanding grow so you can achieve success in these fascinating topics.
