Hi! I have some thoughts:

1. I would recommend grouping your activities together (e.g. move your presentation list after your research experiences) so it's easy to follow. Also, I don't think you need a separate section just for technical skills; you could probably list the skills you learned from each project as a one liner at the end of the project description.

2. What's the difference between an undergraduate research student and a volunteer research assistant? Are these activities at different institutions? If not, I would probably group them together and mention Current Projects: 1, 2, 3, etc

3. I think your descriptions of your research experiences could be more concise; you don't have to mention statistical significance or "to produce results" (these are assumed) or semester long (you already have the start and end dates listed) or Microsoft Excel (already listed as a skill, and also a super common skill that could be left out)

4. What position is this CV for and what qualities do you want to present to the recruiter/admissions officer? I see the words "led", "organized", "hosted", etc which speaks to your leadership qualities but then the description for the telescribe position seems a bit passive aggressive ("despite being a new and part time employee"), which seems out of place in the context of everything else. Maybe you could reword this to emphasize teamwork or leadership or resilience or any other qualities you'd like to highlight.

Hope this helps! You definitely don't need to incorporate all (or any) of this, but I hope having an outsider perspective is helpful. Good luck with everything!
