I hope you are having a fantastic Summer!

Welcome to Chem 201! My name is Ligia Zelaya. Most students address me as Professor. Z, or Lee. Please let me know if you have any nicknames you prefer. 
I have been teaching chemistry courses since 2014. In 2016, I completed a Masters in Biochemistry at California State University, Northridge. My dissertation was based on the synthesis of fluorogenic phosphatidylcholine Derivatives, which was used for Kinetic Studies of Phospholipase A2 Enzymes. In addition to being a professor at SCUHS, I have also been a lecturer at the College of the Canyons, Chaffey College, and Los Angeles Valley College.
In addition to being a devoted educator, my other interests include playing with my puppy "Max," Reading romantic fiction books, Bachata and Salsa dancing, cooking, and hiking. 
I look forward to helping each of you succeed in the upcoming semester.
This class is 16 weeks long, and it will be taught 100% online due to the Covid-19 pandemic. I imagine many of you have anxiety and concerns due to the class being online. I will do my best to give you as much information as possible to feel comfortable and prepare for what is ahead. I have outlined the format/plan for our class this semester, hopefully answering questions you may have.You will need a computer and internet access to complete this course.

If you have any additional questions, please feel free to email me. (I typically respond to emails within 24 hrs).
