Meditation Mob – A Drop-in Mindfulness Meditation Group

Meditation Mob logo

Who We Are and What We Do

The Meditation Mob is a weekly drop-in mindfulness meditation group open to all graduate and undergraduate students.  We meet on Tuesdays from 12:00 - 12:50 on the 9th floor (top floor) of Millikan Library.  It's the tallest building on campus - you can't miss us!  We're in the study room to your left as soon as you step off the elevator.

What is mindfulness?  It's paying attention to your present moment experiences with openness, curiosity, and a willingness to be with what is.  It's a great way to boost your concentration, to feel more engaged in your life, and to manage stressful experiences more easily.  The group is taught from a secular, evidence-based perspective and incorporates relevant research whenever possible.  The facilitator, Dr. Lee Coleman, is a Certified Mindfulness Facilitator through the Semel Institute for Neuroscience and Human Behavior, University of California, Los Angeles.

Each week, we'll have a short introduction to that day's topic, time for Q&A, and then we'll have half an hour of guided meditation.  Whether you're brand new to meditation or already have an established meditation practice, we'd love to have you.  All Caltech students are welcome – come as you are!

The mindfulness meditation exercises taught in this group and hosted below are not a form of psychotherapy and are not intended as any form of psychological treatment.

Mailing List

Join the Meditation Mob e-mail list for weekly reminders about group meetings and occasional updates on mindfulness-related research.


Our new home is on the 9th floor of Millikan Library.  We'll meet there every Tuesday from 12:00 - 12:50 in the study room just to your left when you step off the elevator.  Just's the top floor of the tallest building on campus.

• As of the end of Fall term 2017, we've had over 1,000 attendees since the group's inception.  There are currently 117 subscribers to the weekly mailing list.

• Sit in style!  We have 20 high-quality meditation cushion sets available to anyone who wishes to use them during the group.  Here are some basic instructions on how to find a comfortable sitting posture on a meditation cushion or even in a regular chair.  (294.4 KB PDF, IMSS login required) 

Research Spotlight

Wondering how mindfulness meditation works, what it helps with, and what it doesn't help with?  Here's a great review from a conceptual and neural perspective (322.4 KB PDF), and a 2014 meta-analysis from JAMA (407.6 KB PDF) that shows what mindfulness practice seems to help with.
