hello, ucsd cog sci! 👋


geisel library

I’m super excited to be starting as Assistant Teaching Professor 👩🏻‍🏫 in the Department of Cognitive Science at UCSD!

For the 2025-2026 academic year, I will be teaching:

In the future, I plan to also teach COGS 182: Introduction to Reinforcement Learning, as well as two new courses, one about AI and one about the cognitive science of beliefs (see below).

If you’re a current UCSD student wondering who I am or whether you should take one of the above courses with me, you’re in the right place 😊 As a student, I remember feeling hesitant about taking a course with a brand new professor— How would I know if they’re any good at teaching? So now that I’m the new professor, I want to introduce myself and let you know what you can expect from me as an instructor.

recent teaching evaluations 🔗

It’s one thing to hear about my teaching from me, but it’s often more helpful to hear from students who’ve taken my classes! If you want to skip the rest of this page and go straight to the receipts 🧾, here are some recent teaching evaluations from my former students:

who am I? 🎓

I earned my Ph.D. in Neuroscience from Harvard in 2024, where I worked on developing computational theories of learning and decision making. Before that, I got my B.A. in Cognitive Science from Rice University. I was born in New England ☃️, but mainly grew up in Texas 🤠.

As an Assistant Teaching Professor 1, I focus on designing and teaching high-quality courses that will equip you with fundamental knowledge and skills across several subfields of cognitive science. My research and teaching background spans neuroscience, psychology, psychiatry, machine learning, and behavioral economics. I’m especially passionate about inclusive and innovative pedagogy, active learning, and using AI to augment (but not replace!) how we learn.

my teaching philosophy 👩🏻‍🏫

I’ve been teaching in college classrooms for the last 10 years, and have spent a lot of time thinking about what it means to be a good teacher, what effective learning looks like, and what kind of classroom environment I want to build. Here’s what you can expect if you take a course with me:

FAQs

Are you going to be designing any new courses?

Yes! I’m currently in the process of designing two new COGS courses:

Course Description
COGS 19: Living and Learning with AI Advancements in artificial intelligence (AI) are transforming the way we live, work, and learn. How can we leverage AI’s potential while preserving human ingenuity and intellectual agency? This course equips students to critically engage with and creatively utilize AI through hands-on experimentation. Students will evaluate AI’s capabilities and limitations, examine its impact on work, education, and creativity, and develop strategies for its responsible use.
COGS 113: Cognitive Science of Belief Beliefs motivate our behaviors: they influence who we vote for, whether we take action against climate change, and what we think happens when we die. How do beliefs form, and how are they influenced by social and cognitive factors? Why do some beliefs persist despite conflicting evidence, while others change? This course explores the mechanisms of belief formation and change through experimental and theoretical perspectives.

I expect these courses to be offered for the first time starting in the 2026-2027 academic year.

Do you require attendence?

I don’t require lecture attendence in my courses (it’s often extra credit), but I strive to make class a valuable use of your time. I put effort into designing interactive, engaging lectures that promote active learning (there is a plethora of scientific evidence showing how this approach is more effective for retaining and understanding material). Attending lecture will help you stay on top of the course and reduce the need to play catch-up later. That said, I also value flexibility, so all lectures will be recorded and podcasted!

Can I do research with you?

Not yet—but hopefully soon! During my first year at UCSD, I’ll be focused on developing and teaching several courses for the first time, and I want to make sure they are well-prepped and high-quality. As a result, I will not be recruiting research assistants for the 2025–2026 academic year (but stay tuned in case that changes!).

I am a PhD student, can you be my main supervisor?

As a teaching-focused faculty member, my first priority is providing high-quality undergraduate instruction. That said, I do maintain an active research agenda working on computational models of learning, decision making, and belief change (you can read more about my research here). While I will be focusing my first year at UCSD on teaching, I’m open to advising or co-advising a very limited number of Ph.D. students in the future through the Cognitive Science Ph.D. Program. I’m also happy to serve on dissertation committees where there’s a good research fit.
