Meet the founding partners
Factor Space Forensics was founded by Emily Prokesch and Joseph Cavise on a shared conviction: effective forensic litigation requires more than good scientists, it requires attorneys who have spent their careers at the intersection of courtroom advocacy and forensic evidence. Together, Joey and Emily bring more than 20 years of courtroom experience challenging unreliable forensic evidence in serious criminal cases. They deliver deep expertise that works alongside yours in every engagement to achieve the best results for clients.
Emily Prokesch
Founding Partner
Emily Prokesch is a trial lawyer, forensic consultant, and Lecturer in Law at Columbia Law School, where she teaches Forensic Evidence. Nationally recognized for her work challenging unreliable forensic disciplines and litigating complex scientific evidence, Emily has spent more than a decade representing clients facing serious criminal charges and leading cutting-edge forensic litigation. Emily served as lead counsel in People v. Ross/A.M., the first admissibility hearing in New York State on firearms and toolmark comparison evidence, which resulted in the exclusion of evidence beyond class characteristics as not generally accepted as reliable by the relevant scientific community.

Founding Partner
Joey spent more than a decade as a trial lawyer and leading member of the Law Office of the Cook County Public Defender's Forensic Science Division, where he developed expertise in challenging the reliability and admissibility of forensic evidence. His experience includes challenging methods, techniques, and conclusions in serology, DNA analysis, statistical reporting, pattern-matching evidence, digital surveillance technology, and more. Litigating dozens of homicides, sex assaults, and other serious cases placed him at the forefront of some of the most consequential forensic litigation in the state. He was part of the team in People v. Winfield — the first firearms and toolmark admissibility hearing in Cook County history — and the ground-breaking litigation against the substandard latent print work by the Chicago Police Department's fingerprint unit.
