Dr. Graziano’s research focuses on various factors that impact police-community relations, particularly community policing, the role of race-ethnicity in shaping public perceptions of police, and the impact of media coverage on perceptions of police.  Currently she is working on a project examining race and the Los Angeles Police Department in terms of the evolution of both LAPD relations with communities of colors and diversity within the LAPD itself.


Denise Herz

Professor; Ph.D., University of Maryland-College Park


Dr. Herz is an expert on applied research, particularly building partnerships between research and practice in areas of juvenile justice. Her interest also includes the following areas: substance abuse, mental health, crime and justice system policy, and crossover youth (i.e., maltreated youth who engage in delinquency).


Donald Johnson

Professor of Criminalistics; M.Sc., UCLA


Before joining the faculty in 2003, Johnson was a forensic science practitioner and gained extensive experience in forensic biology, forensic pathology, and crime scene investigation and reconstruction.  Johnson is active in forensic science education, in-service training, and research.  Johnson currently investigates new technologies and novel approaches to advance forensic science.  Johnson recently published on a novel method to further characterize non-specific bloodstain patterns by use of microRNA profiling.


Katherine A. Roberts

Professor; Ph.D., John Jay College, New York


Dr. Roberts is the director of the M.S. program in criminalistics and her research interest focuses primarily on trace evidence. She is currently the P.I. for a National Science Foundation grant to establish the Center for Interdisciplinary Forensic Science Research as a research site within the NSF Industry-University Cooperative Research Center program. She also collaborates with private industry on projects that encompass the detection of adulterants in morphine sulfate solutions, microspectroscopy to differentiate printing inks and bullet damage.

Dr. Vargas is a forensic chemist by training with broad research interests in all areas of forensic chemical analysis, toxicology, and pharmacology. Dr. Vargas has special interests in the development of new analytical techniques for controlled substance analysis, and in the development of animal models for use in determining the adverse effect profile of drugs and toxins. Finally, Dr. Vargas has extensive training in neuroscience and the cellular changes that occur to central nervous system tissue in response to drug exposure and in neurological disorders.
