About Me

Here's where you can find me. ̌


Discoverer in training.

I'm currently a PhD student in Dr. Kevin Ochsner's Social Cognitive & Affective Neuroscience Lab at Columbia University, where I began in fall 2017. While I'm not working on research (and often while I am), I'm probably drinking from a very large cup of tea. I also co-manage an informal R users club in the department, and help to organize bi-weekly meetings/workshops to enrich our collective R experience.


In 2013 I started working as a research assistant on a media multitasking & cognition project with Dr. Melina Uncapher, then a research associate in Dr. Anthony Wagner's Memory Lab, during my freshman year at Stanford University. She couldn't get rid of me, and I continued working with her in the lab throughout undergrad, earning two undergraduate summer fellowships through Stanford (PsychSummer and Bio-X) so I would literally never have to leave. I completed my bachelor's degree in three years, serving as an undergraduate Teaching Fellow for Psych One, Stanford's introductory psychology course, during my third year, while also completing an honors thesis under Drs. Uncapher and Wagner.

After graduation in 2015, I transitioned into a full-time lab manager + research assistant position in the Memory Lab. As lab manager/RA, I served as a jack-of-most-trades, handling various arms of data collection and analysis for our healthy aging study, maintaining lab needs both tangible (office supplies, copies, uncomfortable amounts of coffee) and intangible (IRB protocols, software licenses, moral support), and defusing tense meetings with horrible jokes. I also spent some time assisting Dr. Uncapher with data processing and statistics for her educational neuroscience projects with the Neuroscape group at UC San Francisco.
