DCAIP Intern

May 2021 - December 2021 Quantico, VA
“I liked that I was a government employee learning about the ins-and-outs of the government. I learned about contracting which is something I didn't even know existed before this internship. I was also given advice, tips, and guidance on my resume, interviewing skills, and my options when it came to my future. ”

Forensic Analyst Intern

July 2021 - August 2021 Fort Gillem, GA
“I had the chance to learn from the country's premier forensic analysts working for the Department of Defense. I was introduced to a ton of forensic analysis techniques and got to see how a case is solved from proper sample collection to proper analysis after it's sent to the lab. We discussed some case studies which exposed me to the reality of the forensic field and crime as a whole in our society, and more specifically in our military. ”
