Welcome to my webpage, I look forward to having a wonderful year!
Parents- please take some time to fill out our questionnaire! Mrs. Landry's Parent Survey
I began my education in North East ISD as a first grader at Jackson Keller Elementary School, and Nimitz Middle School.  I graduated from Lee High School and then went on to graduate from Trinity University with a bachelor's degree in Biology and a Mathematics minor. After college I worked in a genetic counseling office and cytogenetic laboratory.  I was involved in tissue culture, microscopy, chromosomal analysis, photography and basic laboratory practices. 

After realizing, that was not the career for me, I returned to Trinity and recieved  my Master of Arts in Teaching. I began teaching  at Lee. I joined the initial team of teachers to found ISA.  I have been committed to ISA since then.   I have taught Biology I, Chemistry I, AP Biology, Anatomy and Physiology, Neurobiology, and AP Environmental Science in my teaching career.  I have mentored Trinity interns and new teachers.  I have attended numerous AP Summer Institute.  I enjoy teaching students scientific thinking and doing experiments.

My life outside of school is filled with my family.  My husband Jeff, and three daughters, Kristin, Erin and Sarah. 
 Here is a short introduction to Dr. Embry, my student teacher for the 2020-2021 academic year.

Hello and welcome to some Advanced Science courses!

My name is Addie Embry. I am a native Texan and happy to call San Antonio my forever home. As you can tell from the “Dr.” in front of my name and my age, I’m a little bit of a different sort of ISA student teaching intern. 

I grew up in San Angelo, TX and went to San Angelo Central High School where I had some amazing science teachers. I developed a desire to study genetics and attended Texas A&M in College Station for undergrad where I graduated with a B.S. in Genetics. After college, I worked in a research lab in Houston, TX and from there decided to go to graduate school to pursue a Ph.D. in Microbiology. I was (and still am) really into pathogens, especially viruses. I ended up working on my doctorate in a poxvirus lab at UTHSCSA here in San Antonio and earned my Ph.D. in Microbiology and Immunology in 2011. From there, I worked as a research scientist in several different places and on several different projects. I have worked on projects in vaccine immunology, virus morphogenesis, kidney disease, cancer immunotherapies, and pre-mRNA splicing, and have published several papers along the way.

My last research stop was at Trinity University where I studied RNA. At Trinity, I discovered a love of teaching through working in the lab with undergraduate student researchers and teaching Biology labs. Last year, I decided to join the Trinity Masters in the Art of Teaching (MAT) program to really learn how to teach. I love working with high school and college students! I hope that my love of science is infectious and that you learn and have fun in the AP courses you are taking this year with Mrs. Landry and me.

I currently live with my husband and fur family in San Antonio. We are the proud owners of one dog (Marley) and three cats (Leif, Ziffy, and Isis (aka Pickle)). I am happy to show you pictures if you’d like to see them.

See you in class!

  • Here is the link to my Bitmoji classroom.  Go here to find LOTS more information about my classes.

  • I believe students are capable of higher level thinking and planning this is a daily activity.  Students deserve a chance to work on challenging materials and labs and I want to encourage students to challenge themselves.  I believe in making class fun and engaging for the students.  I try to plan so that every student has an opportunity to learn in their preferred manner.  I think discussions, both small and large groups can lead to impactful learning.  I want students who can think and analyze data as scientists. Who will be productive and active community members.
