Techers take over our Instagram account

The Caltech Alumni Association asked Techers to take over our Instagram account (@caltechalumni) and share their experiences and perspectives after graduation. From pursuing a passion for medical research to chasing nature photos while foraging for food along the way, alumni are showing us the diversity of their experiences in their lives after Caltech.

We invite you to share a glimpse of your life with us, your fellow alumni, and current students by using the hashtag #LifeAfterCaltech on social media. 



After Caltech, Jen Yu(@jenyuphoto and @userealbutter) worked at the Jet Propulsion Laboratory, earned a doctorate in geology, returned to work at Caltech in GPS, and eventually settled in the Rocky Mountains of Colorado with fellow Techer Jeremy Darling (BS ’96). After her breast cancer diagnosis in 2007, Jen left science and became a freelance photographer and food blogger.

I share my love of wild things and wild places through my nature and landscape photography. Most of my work involves the American West, but the past few years I have remained close to home in the Colorado mountains.
Foraging bridges the gap between my nature photography and food photography. Not all of the recipes I test, photograph, and blog involve wild foods, but I do enjoy incorporating them into my work.


After Caltech, Andrew Freddo (@amf913) pursued a passion for medical research and is now a first-year resident at the University of Colorado in the combined Internal Medicine-Pediatrics program. After residency, he plans a career combining both research and patient care, possibly in adult congenital cardiology.

One of the biggest surprises and joys in my life after graduating Tech was finding the love of my life! He makes me laugh every single day, keeps me humble, and always is ready for new adventures. And now we’re engaged … wedding date TBD!


After Caltech, Adrianne Yang (@adrianne.yang) became an environmental engineer, honing her skills in site remediation, water quality monitoring, civil design, and mining water management. She is a registered professional engineer in the state of Washington and currently works at Jacobs Engineering as a water management modeler. She is also married to fellow alumnus Yifan Yang (BS ’00) and mom of two kids, Sam and Rae.

In my job, I need to be conversant with geochemists, engineers, statisticians, regulators, and my clients. My education at Caltech gave me the basis for succeeding at this aspect of my job. This LEGO mini figure sits on my desk to remind me of my roots.


After Caltech, Lily Chang (@cryptgirl) became a bridge construction engineer for the California Department of Transportation. Currently on a loan assignment in Sacramento, Lily is enjoying the local food, art, and culture until her return to Los Angeles to continue field work.
