Dr. Yu is a Professor in the Department of Forensic Science at Sam Houston State University. He is an analytical chemist specializing in forensic science. He obtained his BS and MS degrees both in Forensic Science from Central Police University in Taiwan. From 1994 to 2002, he worked as a forensic scientist at the Forensic Science Center in Taipei, Taiwan. Dr. Yu completed his PhD in Chemistry from Carleton University, Ottawa, Canada, in 2006.

Dr. Yu was promoted to Fellow with the American Academy of Forensic Sciences in 2014. He also holds a forensic certificate (Diplomat-ABC) with the American Board of Criminalistics in the certification area of comprehensive criminalistics. His research interest is in the areas of trace evidence examination and crime scene reconstruction. The ultimate goal in his research laboratory is to develop investigative intelligence by chemical forensics.

Research Interests:

Dr. Yu's research interests include topics in Forensic Chemistry such as the Chemical Profiling of Marijuana and the Application of Headspace Solid Phase Microextraction for Chemical Analysis of Trace Evidence. Chemical information association with marijuana may offer critical investigative intelligence in criminal investigation. Our research interest focuses on the development of reliable analytical platforms that will meet the standards of forensic science. The use of headspace solid phase microextraction to sample headspace chemicals from trace evidence is a nearly non-destructive sampling process to extract signature compounds from the evidence. It is our research interest to expand this analytical platform for chemical forensics. In addition, Dr. Yu is interested in Trace Evidence and Crime Scene Management, specifically toolmark examination of 3D printed metallic materials. 3D printing, also known as additive manufacturing, is a process of making solid objects from a digital file. With popularity of this technology, 3D metal printers can now produce weapons. Our interest is to examine toolmarks produced from 3D printed metallic products. With the paradigm shift of trace evidence, integrating physical evidence within the context of the crime scene is becoming one of the major focuses of this discipline. One of our research interests is to develop a system or a model that can promote the use of trace evidence for high quality crime scene investigation.
