When introducing yourself in a professional setting I would recommend giving the person an "elevator pitch". An elevator pitch is meant to be a very quick summary of who you are and how it relates to the person you are talking to. I can't really speak about being a marine biologist, but here is an example of what I would say:

I've recently had the opportunity to help my client navigate new accounting guidance that required me to research the proper literature and how it applied to their company. I was able to help transition the accounting department by clearly showing the client the difference between what they were currently doing and highlighting the impact of this change on their financial numbers. Not only did I really enjoy developing my problem solving and researching skills, but also helping my client.
Joseph recommends the following next steps:
- Research about the company/person you are talking to, so you know the most relevant things to say to them.
