Valerie Foster

Biography
I attended Mt. San Antonio College out of high school and transferred to UC Berkeley where I obtained a BA in Integrative Biology. After taking 1 year off to be a substitute teacher for the Contra Costa Unified School District, I went straight into a Ph.D. program at UC Irvine where I studied the evolution of parental care in zebra finches. I found my passion for teaching during my time as a teaching assistant at UCI and took advantage of every professional development opportunity about teaching that the college offered. I was a first generation college student and had to navigate the higher education system on my own; my successes and failures have greatly influenced my project-based teaching approach. I believe that it is important for students to be able to develop the skills necessary for them to become conscientious citizens and professionals during their college education. Rather than marching through the text-book, I develop projects and activities that are focused on real-life problems and systems that students find engaging. I also use culturally responsive teaching practices and culturally relevant material in my courses and hope to continue to improve their integration in the future so that all students feel confident and can thrive. When I am not working, most of my time is dedicated to raising a strong, happy, and confident daughter. We love to camp, travel, dance, bake, read and create, just to name a few things!

Alexandra Garcia

Where are you from?
1st Gen Mexican American LA native

Biography
I have been teaching at PCC since Fall 2018 and I absolutely love being here! I received both my B.S and M.S degrees in Biology at Cal State LA and I have a soft spot for certain subjects like plant ecology, evolution, and climate change. So far, I have taught General Biology, Human Impact on the Environment, and Physiology while at PCC, but I have experience teaching Life Sciences to future Elementary Teachers and Introductory Biology to science majors as well.

I’m constantly improving my teaching skills to be a strong mentor in my student’s learning process. My mission philosophy is to make the content I am teaching meaningful, whether the individual is a biology major or not. Communicating science effectively is something that our society needs to improve on, and I want to be that individual to make a positive change in scientific literacy!

As for winding down, I LOVE to play soccer and I have just started a new hobby, roller skating. I also enjoy going to music shows, as it’s a whole another level of feelings when experiencing live music!

Nicholas W. Hatch, Ph.D.

Where are you from?
Kentucky

Biography
I don’t believe that my education makes me better than anyone else. It makes me a better me. And your education will make you a better you. Folks get pretty hung up on education and titles, but this human hierarchy gets in the way of knowing each other for who we are. So y’all can call me Nick, because I’m here to serve you, and my title doesn’t change that.

For what it’s worth, my doctorate is in Nutritional Science from the University of Kentucky, where I completed dissertation research entitled “Deficiency of microsomal prostaglandin E synthase-1 attenuates the development of diet-induced obesity.” In other words, I demonstrated that mice missing one specific protein gained less weight than normal mice on a diet of mostly lard.

Although “The sun shines bright on my old Kentucky home” (a line from Kentucky’s state song), I now find myself in much sunnier California. After finishing my doctorate, I completed post-doctoral research at UCLA (much like medical doctors complete a residency after graduating) and then continued on to discover a career at PCC that I never would have imagined for myself. I teach of course, but the work of interrupting systems of advantage in higher education and advocating for formerly incarcerated/system-impacted scholars has given me a greater purpose beyond just teaching my specialty. I hope that as y’all pursue your own careers, you’ll remember that seeking justice is work that everyone should pursue, regardless of their specialty.
