Justice, Equity, Diversity, and Inclusion (JEDI)

At Mammoth, we are committed to maintaining a supportive community for all employees. Our Employee Resource Groups (ERGs) provide allyship, enhance career development, and contribute to employees’ personal growth. They are a vital tool in our efforts to make JEDI a key component of Mammoth’s success. With over 150 employees, we have highly motivated groups (highlighted below) tasked with providing resources to individuals from different teams, with different interests, and with different identities. As we continue to expand, we will encourage collaboration and synergy between these groups to support a diversity of initiatives that celebrate, teach, and implement JEDI principles.

  • Team Unity, Socials and Culture (TUSC)

    Driving team unity and culture

    The Team Unity, Socials and Culture (TUSC) groups at Mammoth aim to foster a collaborative cross-functional community and to support personal and professional growth for employees.

  • Womxn and Allies at Mammoth (WAM)

    Empowering womxn at Mammoth

    WAM leads efforts to empower womxn and allies and elevate them to their full potential at Mammoth and beyond.

  • Diversity as a driving force at Mammoth

    The core of our team

    Diversity powers everything we do at Mammoth. Our technology’s strength lies in the diversity of CRISPR systems, and our team’s strength lies in the diverse people and perspectives that guide us. Our ERGs, TUSC, and WAM are designed to ensure diverse people and perspectives shine.


Hear from team members

“I joined WAM to celebrate how lucky I am to work with amazing womxn and allies on scientific advancements and far-reaching ideas. At WAM events and meetings, I have been able to grow by listening to my colleagues, learning about their experiences, exchanging ideas, sharing who I am, and giving back.”

Clare Fasching

Senior Manager, Clinical and Assay R&D

“I joined WAM to help empower and elevate women to their fullest potential at Mammoth and beyond. In my field (patent law), recent statistics show that women continue to be underrepresented as inventors and these disparities are compounded for racially diverse minorities.”

Rachel Herder

VP of Intellectual Property and Associate General Counsel

“I joined TUSC because I wanted to be involved in fostering a fun and collaborative work environment within my team and to help plan environmental conservation related activities. After joining TUSC, I am proud to have been involved in spearheading a relationship with local zoos and planning team volunteering days to help maintain animal enclosures and zoo grounds.”

Ymer Bjornson

Research Associate

“I am fortunate to get to work with many brilliant, talented, and kind womxn and allies. I joined WAM for the opportunity to find a community of colleagues who share a passion for equity at Mammoth and beyond. Being a part of WAM allows me to show up as myself in a safe and welcoming space, and connect with these colleagues on a deeper level than I can in the day-to-day.”

Jenny Speer

Senior Director of People

“WAM embodies a vital aspect of work culture that is very close to my heart – giving a voice to and a supportive tribe for the many passionate, creative, and aspirational womxn who are so often invisible. WAM has a vibrant, diverse, and comforting vibe. It’s an absolute treat to be a part of this community!”

Subhadra Jayaraman


“We started WAM to acknowledge and combat the workplace challenges that uniquely or disproportionately impact womxn and, through my involvement, I hope I’ve helped sow the seeds for a community that will benefit Mammoth and all womxn in science far into the future.”

Julie Choe

Project Manager

“I love being part of TUSC Dx because it gives me a platform to meet and connect with my coworkers across the diagnostics division at Mammoth. The TUSC group is passionate about fostering collaboration between our diagnostic teammates, and provides the resources needed to support that goal.”

Sadie Eicher

Product Manager

“I joined TUSC to have an opportunity to collaborate with my colleagues outside of work in a fun and meaningful way! It’s extremely rewarding to be able to participate in and organize activities that help support our community both within and outside of Mammoth.”

Sonal Jain

Associate Scientist

“As a part of the Mammoth family, there is so much more than just getting the job done. Joining TUSC gave me the opportunity to appreciate, contribute to, and promote a happy working environment.”

Celebrating diverse scientists

When we recently moved into our new space in Brisbane, CA, we were faced with a large number of blank walls. Rather than fill these with corporate artwork, we commissioned local artists to create portraits of historical and contemporary scientists from underrepresented backgrounds. Our conference rooms are now filled with these portraits!

Community outreach

Mammoth regularly engages with the local community through outreach activities including fundraisers, volunteer opportunities, and workshops. The WAM committee recently worked with the San Francisco nonprofit, “La Casa De Las Madres” to raise awareness of domestic violence and healthy relationships. Mammoth team members raised thousands of dollars for the nonprofit and made bracelets that La Casa uses as teaching tools in their efforts to educate teens about teen dating violence.

Movember at Mammoth

For Movember 2021, the JEDI and TUSC committees organized an event where Mammoth team members could safely discuss men’s mental health and mental health awareness. We plan to hold this event annually in recognition of this ongoing issue.
