Behind First Light Fusion is a team of over 100 talented scientists, engineers, technicians and business experts. Our team come from a range of backgrounds but are all united by a passion for realising fusion energy at scale.

In the latest installment of our ‘Meet the Team’ series, we hear from Mo Sasi, a former First Light Engineer who now supports our fundraising efforts as an Investment Manager. Find out why Mo thinks fusion energy could hold the key to the world's future energy security and
why every day is a school day at First Light HQ, below.

1. What is your role at First Light Fusion?


I joined First Light in January 2021 as a Pulsed Power Engineer. I was responsible for operating our in-house pulsed power drivers, as well as designing the next generation drivers. Pulsed Power uses electrical energy to drive high velocity projectiles for use in inertial confinement fusion experiments. Whilst working on a future driver, Machine 4, my role developed into project coordination and managing interfaces for the different components whilst integrating the driver into a world-class scientific facility. I’ve since moved into a new role as Investment Manager, where my responsibilities will focus on securing fundraising to help drive our technology forward.


2. What did you do before FLF and why did you want to join the First Light team?


Before joining First Light, I completed a master’s degree in engineering physics in which I gained a broad understanding of physics, engineering, and material science, with a particular focus on renewable energies. My interest in renewable energies and passion for science then led me to First Light. Fusion was something I had been hearing about for a while, and the opportunity to help tackle the fusion challenge and be involved in something that could really make a difference was one I couldn't pass up.


3. What most excites you about the future of fusion energy?


The thing that excites me most about the future of fusion is how it could be implemented in different environments, regardless of whether the wind is blowing or the sun shining. I think that energy generation should be diverse and needs to cater to these different environments and climates. As demand grows and the world advances, stable energy sources are undeniably important for moving forward into the future. I believe that fusion energy is a part of the solution.


4. What advice to do you have for someone interested in working in fusion or physics?


There are endless amounts of learning opportunities in physics. If you’re curious and enjoy solving problems, it’s definitely the field to be in. I’ve learnt so much already, and constantly feel inspired to keep learning. Fusion in particular is growing in momentum, it’s a great place to learn a lot quickly, and there’s multiple facets to get involved with and contribute to the bigger picture.


5. When you’re not at work, what do you enjoy doing?


I enjoy keeping fit through weightlifting and running. I’m enthusiastic about learning, and constantly looking to broaden my knowledge, particularly in technology, geography, history, as well as prioritising self-development. I enjoy cooking and hosting get-togethers, and in my spare time, I also love playing video games with friends.


6. What is your favourite thing about working at First Light?


The thing I enjoy most about working at First Light is being surrounded by talented and inquisitive people who are excited to share knowledge and discuss ideas. Joining as a graduate was exciting as well as a bit daunting, but I always felt that I was part of the conversation, and my opinions and suggestions were listened to and appreciated. Learning and developing is a big part of the culture at First Light, and I’ve received incredible support when exploring different roles and responsibilities.
