Anselm Dannecker
German by birth, accent and weird mannerisms; currently based in Somerville, MA with my wife.
I am a Fellow at the Negotiation and Conflict Resolution Collaboratory at HKS currently focussing on climate negotiations. Negotiation consulting and trainings on the side.
Interested in changing my interests about every other week: Currently, I cannot get enough of the history of negotiation (esp. sovereign debt negotiations) and behavioral neurosciences.
I am fascinated by hearing about the pathways of people especially when they are very far away from “home.” Love talking about Vanagons, remote life and cooking; hate talking about visa issues but tend to do it a lot. Since this year, I identify as a climber in the hope that I will keep at it if I truly believe in being one.
Elise J. Willer
Currently residing in the Green Mountains of Vermont… increasingly eager though to travel again.
Trained mediator, working as a consultant in negotiation, conflict and having tough conversations (with ourselves and with others).
Interested in building an intentionally diverse work portfolio both in activity (training, facilitating, mediating, coaching, etc.) and type of client (non-profit, for-profit domestic, int’l, gov’t, etc).
Intrigued by cultural difference and its impact on our behavior in moments of tension and conflict and yet regularly reminded (and amused) by how similar we actually are.
I love learning about people, particularly their passions and listening to them reflect on their raison d’être.
Stacy Lennon
I live in Carlisle, MA with spouse Dan, kids Gus (9) and Aoife (7), and pandemic puppy Pepper (1.75)
Currently I’m a lecturer on conflict resolution and leadership at Tufts University in graduate-level entrepreneurship programs
I’ve worked on international peacebuilding efforts (US-Iran) and led negotiation and difficult conversations sessions for NGOs/INGOs/IOs.
My degrees are in architecture & urban planning (MIT) and international relations (Fletcher)
After many years as a road warrior doing corporate workshops (including myriad Zoom sessions during Covid), I’m pausing much of my work to reassess what I’m doing and why
I love architectural design and CAD; decluttering & organizing hacks; dog rescue videos; personal finance; rowing on my ergometer; local politics
Joe Bubman
I live in Los Angeles with my wife Molly and 1-year-old daughter Coralai
I’m founder and Executive Director of Urban Rural Action, a national grassroots movement that brings together Americans across divides to tackle our country’s most urgent challenges.
Interested in U.S. peacebuilding and bridge-building leaders and organizations
Enjoys talking about dialogue, negotiation, and peacebuilding
Loves fun, friendly individual and team competition!

Billy Ford
I'm on the Burma team at the U.S. Institute of Peace. I've worked on various elements of Burma's development for the past 10 years. At USIP, my work focuses on all sorts of peacebuilding-ish stuff - it really depends on what Burma is wrestling with at any particular moment, which is a lot right now.
My current work focuses on supporting various elements of the anti-coup resistance movement, including to local governance structures in liberated areas, various educational initiatives, and to this interesting new nation-building platform that also functions as a mechanism for building opposition unity.
Before USIP, I worked with Freedom House, The Asia Foundation, and a few other Burmese organizations. I lived in Burma for two years as Freedom House’s Country Representative and did stints in Vietnam and Malaysia before that.
I did a Master's in Public Policy at UC Berkeley (where my partner is about to start her PhD!), and my undergrad in Religious Studies from Hamilton College.
My non-Burma interests tend to meander, but I'm currently kinda interested in various elements of existential risk and the related policy challenges (highly recommend the 80,000 Hours Podcast!).
