What is the name of the forensic analyst and Dexter's colleague?

Vince Masuka is the forensic analyst and Dexter Morgan’s colleague in Dexter. He serves as Miami Metro’s lead forensic science investigator, working with Dexter in the laboratory and at crime scenes.

Masuka is recognized for his technical expertise, especially in forensic examination, but he is also known for inappropriate jokes and exaggerated sexual humor. Beneath that comic role, he is a loyal member of the department and an experienced investigator whose scientific work helps advance many cases.

C. S. Lee portrays Masuka in the original television series. The character is sometimes confused with Angel Batista or James Doakes, who are also Miami Metro colleagues, while Tom Matthews is a lieutenant and administrator. Dexter himself is a blood-spatter analyst, but the character specifically identified as the department’s lead forensic investigator working alongside him is Masuka.
